1. The Collapsing Scaffold

Intermediate
30 min

Fact Pattern

GreenBuild Construction Company was hired by Prestige Office Park to renovate the exterior facade of a six-story commercial building in downtown Easton. GreenBuild subcontracted the scaffolding installation to QuickRig Scaffolding, Inc., a company with a mixed safety record that had received two OSHA citations in the prior eighteen months. GreenBuild's project manager, Dana, reviewed QuickRig's bid but did not check its safety history before awarding the subcontract. The Easton Municipal Code, Section 14-302, requires that all scaffolding on commercial buildings be inspected by a licensed structural engineer before workers are permitted on the structure. QuickRig erected the scaffolding over a weekend and did not arrange for an inspection. On Monday morning, Tom, a GreenBuild employee, climbed the scaffolding to begin work on the fourth floor. At the same time, Priya, a pedestrian, was walking on the public sidewalk below the building on her way to a nearby coffee shop. A coupling on the scaffolding's northeast corner failed due to metal fatigue that a competent inspection would have detected. The fourth-floor platform buckled, and Tom fell approximately thirty-five feet. His body struck Priya on the sidewalk, and both were seriously injured. Tom suffered a broken pelvis, two fractured vertebrae, and a traumatic brain injury. Priya suffered a shattered collarbone and severe post-traumatic stress disorder. At the hospital, an emergency room physician, Dr. Ellis, negligently misread Tom's CT scan and failed to identify a slow subdural hematoma. Tom's neurological condition worsened over the next twelve hours, resulting in permanent cognitive impairment that competent treatment would have reduced to a temporary condition.

Call of the Question

Analyze all potential tort claims and defenses available to Tom and Priya against GreenBuild, QuickRig, and Dr. Ellis. Discuss the liability of each defendant and any comparative fault issues.

Model Answer

Tom v. QuickRig -- Negligence Issue: Whether QuickRig breached a duty of care to Tom by erecting scaffolding without a required inspection. Rule: A defendant owes a duty of reasonable care to all foreseeable plaintiffs. Under the doctrine of negligence per se, violation of a statute designed to protect a particular class of persons from a particular type of harm establishes both duty and breach as a matter of law. Martin v. Herzog (1920). The Easton Municipal Code Section 14-302 requires inspection of commercial scaffolding by a licensed structural engineer before workers may use the structure. Application: Tom, a construction worker who would climb the scaffolding, falls squarely within the class of persons the ordinance was designed to protect. The harm suffered -- a fall caused by an undetected structural defect -- is precisely the type of harm the inspection requirement was enacted to prevent. QuickRig erected the scaffolding and bore the responsibility for arranging the inspection. Its failure to do so constitutes negligence per se, establishing both duty and breach. Actual cause is satisfied under the but-for test: but for the failure to inspect, the metal fatigue in the coupling would have been discovered and the platform would not have buckled. Proximate cause is also clear, as a worker falling from uninspected scaffolding is a foreseeable consequence of skipping a mandatory safety check. Tom suffered severe physical injuries, satisfying the damages element. Conclusion: Tom has a strong negligence per se claim against QuickRig, and QuickRig will likely be held liable. Tom v. GreenBuild -- Negligent Hiring/Supervision of Subcontractor Issue: Whether GreenBuild is liable for negligently selecting QuickRig as a subcontractor. Rule: A general contractor that hires an independent contractor is generally not vicariously liable for the contractor's negligence under the independent contractor rule. However, a principal has a non-delegable duty to exercise reasonable care in selecting competent contractors. Restatement (Second) of Torts Section 411. Where the work involves a peculiar risk of harm to others, the hiring party may also retain a non-delegable duty of care. Additionally, a party cannot delegate a duty imposed by statute. Restatement (Second) of Torts Section 424. Application: GreenBuild's project manager Dana failed to check QuickRig's safety history before awarding the subcontract. QuickRig had received two OSHA citations in the prior eighteen months -- a red flag that a reasonable general contractor would have discovered through basic due diligence. This failure to investigate supports a claim for negligent hiring. Furthermore, the statutory duty under Section 14-302 to ensure scaffolding inspection is arguably non-delegable. GreenBuild, as the general contractor responsible for the job site, cannot escape liability simply by passing the inspection obligation to a subcontractor. A court would likely find that GreenBuild retained a duty to ensure compliance. But-for GreenBuild's negligent selection of QuickRig, a competent scaffolding company would have arranged the required inspection and the defect would have been caught. Conclusion: GreenBuild is likely liable to Tom under both negligent hiring and the non-delegable duty doctrine. Priya v. QuickRig and GreenBuild -- Negligence Issue: Whether Priya, a pedestrian on a public sidewalk, can recover against QuickRig and GreenBuild. Rule: A defendant owes a duty of care to all foreseeable plaintiffs within the zone of danger created by the defendant's negligent conduct. Palsgraf v. Long Island Railroad Co. (1928) (Cardozo, J.). The negligence per se and negligent hiring analyses above establish breach. The question is whether Priya is a foreseeable plaintiff. Application: A pedestrian walking on the sidewalk below construction scaffolding is clearly within the zone of danger when scaffolding collapses. Falling debris, equipment, and even workers are foreseeable risks to persons below a construction site, which is precisely why inspection requirements exist. Although Section 14-302 is primarily aimed at protecting workers, a court could find that pedestrians in the immediate vicinity are also within the protected class or, alternatively, that general negligence principles independently establish the duty. Priya's injuries -- a shattered collarbone from being struck by Tom's falling body and PTSD from the traumatic event -- are the direct and foreseeable result of the scaffolding failure. Proximate cause is satisfied because harm to pedestrians below collapsing scaffolding is not a remote or unforeseeable consequence. Conclusion: Priya has strong negligence claims against both QuickRig and GreenBuild. Tom v. Dr. Ellis -- Medical Malpractice Issue: Whether Dr. Ellis is liable for the aggravation of Tom's injuries due to the misread CT scan. Rule: A physician owes a duty to exercise the degree of care, skill, and treatment that a reasonably competent physician in the same specialty would provide under similar circumstances. A physician who negligently fails to diagnose a condition is liable for the additional harm caused by the delay in treatment, but not for the original injury. The plaintiff must show, through expert testimony, that the misdiagnosis was the but-for cause of the worsened outcome. Application: Dr. Ellis negligently misread Tom's CT scan and failed to identify a slow subdural hematoma. The facts state that competent treatment would have reduced Tom's condition from permanent cognitive impairment to a temporary condition. This establishes both breach and causation for the enhanced injury. Dr. Ellis is not liable for Tom's initial injuries from the fall -- the broken pelvis and fractured vertebrae -- but is liable for the difference between the permanent cognitive impairment Tom actually suffers and the temporary condition he would have experienced with proper diagnosis. This is sometimes called the "loss of chance" or "enhanced injury" doctrine. Conclusion: Dr. Ellis is liable to Tom for the aggravation of his neurological injury, measured as the difference between his actual condition and the condition he would have been in with timely treatment. Comparative Fault and Apportionment Issue: Whether any comparative fault applies and how damages should be apportioned among defendants. Rule: Under modern comparative fault systems, a jury apportions fault among all parties, including negligent defendants and, where applicable, the plaintiff. Joint tortfeasors whose negligence combines to produce a single indivisible injury are jointly and severally liable in many jurisdictions, with a right of contribution among them. Where injuries are divisible, each defendant is liable only for the harm it caused. Application: Tom does not appear to have been contributorily negligent -- he simply arrived at work and climbed scaffolding he had no reason to believe was uninspected. QuickRig and GreenBuild are joint tortfeasors whose independent negligence combined to produce Tom's fall injuries. They are jointly and severally liable for those injuries. Dr. Ellis is a successive tortfeasor liable only for the enhanced neurological harm. As to Priya, neither she nor any other party appears at fault for her injuries; QuickRig and GreenBuild would be jointly and severally liable for her full damages. A jury would apportion fault between QuickRig and GreenBuild for contribution purposes, likely assigning more fault to QuickRig as the party directly responsible for the scaffolding but significant fault to GreenBuild for failing to vet the subcontractor and for its non-delegable duty. Conclusion: QuickRig and GreenBuild are jointly and severally liable for both Tom's and Priya's injuries from the fall. Dr. Ellis is liable only for the enhanced neurological damage Tom suffered due to the misdiagnosis.

Issues Checklist

  • Negligence per se based on violation of Easton Municipal Code Section 14-302
  • Negligent hiring and selection of an independent contractor
  • Non-delegable duty doctrine
  • Foreseeability of Priya as a bystander plaintiff under Palsgraf
  • Medical malpractice and the enhanced injury doctrine
  • Joint and several liability among concurrent tortfeasors
  • Apportionment of damages between original and successive tortfeasors
  • But-for and proximate causation analysis for each defendant

Key Rules Tested

Negligence per se -- violation of a safety statute establishes duty and breachNon-delegable duty doctrine -- certain duties cannot be delegated to independent contractorsPalsgraf zone of danger test for duty to foreseeable plaintiffsMedical malpractice standard of care and enhanced injury liabilityJoint and several liability for indivisible injuries

Common Mistakes

  • Failing to analyze GreenBuild's independent liability and simply concluding it is vicariously liable for QuickRig's negligence as an employer, when QuickRig is actually an independent contractor
  • Not separating Dr. Ellis's liability to the enhanced injury only, and instead holding the doctor liable for all of Tom's injuries
  • Ignoring the negligence per se framework and analyzing the scaffolding failure under ordinary negligence only
  • Failing to address Priya's standing under the negligence per se statute versus general negligence principles

Grading Notes

This is a relatively straightforward multi-party negligence question designed to test foundational doctrine. An A answer will methodically address each defendant's liability to each plaintiff separately, correctly identify and apply negligence per se, distinguish GreenBuild's liability from vicarious liability by identifying the negligent hiring and non-delegable duty theories, and precisely limit Dr. Ellis's exposure to the enhanced injury. The strongest answers will also analyze whether Priya falls within the protected class of the statute or must rely on general negligence duty analysis. A B answer typically collapses the analysis, treating all defendants as equally liable, or fails to recognize the divisibility of Tom's injuries between the construction defendants and Dr. Ellis. Professors reward students who show they understand that the same injury can involve both concurrent and successive tortfeasors with different liability exposures.

2. The Backyard Bonfire

Intermediate
30 min

Fact Pattern

On the evening of October 18, Carl hosted a bonfire party at his rural property in Jefferson County. Carl had built a large fire pit approximately forty feet from the property line he shares with his neighbor, Helen. Jefferson County Ordinance 7.04 prohibits open fires within fifty feet of any adjoining property line without the written consent of the adjacent landowner. Carl did not obtain Helen's consent. Approximately twenty guests attended the party, and Carl provided substantial quantities of beer and hard liquor at no cost. Around 10 p.m., one of the guests, Marcus, who had consumed seven or eight beers over three hours, decided to impress other guests by attempting to jump over the bonfire. Carl saw Marcus approaching the fire and shouted, "Don't be an idiot, Marcus!" but made no physical effort to stop him. Marcus leaped, caught his foot on a log at the edge of the pit, and fell into the fire. He suffered severe burns to his arms and torso. Several guests, including Nora, rushed to pull Marcus out. In the chaos, a burning log rolled out of the pit and ignited dry brush near the property line. The fire spread onto Helen's property, destroying her garden shed and a collection of antique furniture stored inside, valued at approximately $45,000. Nora, while pulling Marcus from the fire, suffered second-degree burns on both hands. Marcus was airlifted to a regional burn center. During transport, the helicopter pilot, employed by MedFlight Inc., negligently flew into known turbulence despite weather advisories, causing the helicopter to lurch violently. Marcus, already in critical condition, sustained a spinal cord injury from being thrown against the interior of the aircraft. Marcus is now paralyzed from the waist down in addition to his burn injuries. Jefferson County is a modified comparative fault jurisdiction with a 50% bar, meaning a plaintiff whose fault equals or exceeds 50% is completely barred from recovery.

Call of the Question

Discuss all tort claims that Marcus, Nora, and Helen may bring against Carl and any other potentially liable parties. Analyze all applicable defenses, including comparative fault, and predict likely outcomes.

Model Answer

Marcus v. Carl -- Negligence (Social Host Liability and Negligence Per Se) Issue: Whether Carl, as a social host who provided free alcohol, owed and breached a duty of care to Marcus. Rule: At common law, a social host generally owes no duty to prevent intoxicated adult guests from injuring themselves, because voluntary intoxication is considered a superseding cause. However, some jurisdictions have recognized limited social host liability where the host continues to serve alcohol to a visibly intoxicated guest and the host knew or should have known that the guest would engage in dangerous activity. Additionally, a landowner owes a duty of reasonable care to invited guests to maintain the premises in a reasonably safe condition and to warn of or protect against known hazards. Negligence per se may also apply where a host violates a fire safety ordinance. Application: Carl provided large quantities of alcohol and Marcus consumed seven or eight beers over three hours, making him visibly intoxicated. Carl was aware of the danger when Marcus approached the fire -- he shouted a warning but took no physical action to intervene. A strong argument exists that Carl breached his duty as a premises owner by hosting a bonfire (an inherently dangerous condition) and providing unlimited alcohol without taking reasonable precautions such as barriers around the fire pit, designated sober monitors, or physically intervening when Marcus approached. The negligence per se argument based on the fire ordinance is weaker as applied to Marcus's claim because the ordinance (prohibiting fires within fifty feet of a property line) was designed to protect neighboring property from fire spread, not to protect party guests from burning themselves. Marcus is arguably outside the protected class. However, Marcus's own comparative fault is substantial. He was an adult who voluntarily consumed excessive alcohol and made a deliberate, foolish decision to jump over a bonfire. In a modified comparative fault jurisdiction with a 50% bar, if the jury finds Marcus 50% or more at fault, he recovers nothing. A jury could reasonably find Marcus predominantly at fault for his own injuries given the voluntary and reckless nature of his conduct. Conclusion: Carl likely owed a duty as a premises owner, and his failure to take precautions beyond a verbal warning may constitute breach. However, Marcus's recovery is precarious because his comparative fault may equal or exceed 50%, barring his claim entirely under the jurisdiction's modified comparative fault rule. Marcus v. MedFlight Inc. -- Negligence (Vicarious Liability) Issue: Whether MedFlight is vicariously liable for the helicopter pilot's negligence that caused Marcus's spinal cord injury. Rule: Under respondeat superior, an employer is vicariously liable for the tortious acts of its employees committed within the scope of employment. A medical transport company owes the highest degree of care to its patients. A negligent act by a rescuer or medical provider is generally considered a foreseeable intervening cause, not a superseding cause, because the need for rescue was created by the original tortfeasor's negligence. Restatement (Second) of Torts Section 457. Application: The pilot was employed by MedFlight and was acting within the scope of employment while transporting Marcus. The pilot negligently flew into known turbulence despite weather advisories, breaching the duty of care owed to the patient. This negligence was the but-for and proximate cause of Marcus's spinal cord injury, which is a distinct and separable harm from the burn injuries. MedFlight is vicariously liable. Marcus's comparative fault in causing the original accident does not bar a claim against MedFlight for the independent spinal injury because Marcus was a helpless patient at the time of the pilot's negligence and bore no fault for the helicopter incident. Conclusion: Marcus has a strong claim against MedFlight for the spinal cord injury, and his intoxication and bonfire jumping would not constitute comparative fault as to MedFlight's independent negligence. Nora v. Carl -- Rescue Doctrine Issue: Whether Carl is liable for Nora's burn injuries sustained while rescuing Marcus. Rule: Under the rescue doctrine, a tortfeasor whose negligence places a person in peril is also liable to those who are injured while attempting a reasonable rescue. "Danger invites rescue." Wagner v. International Railway Co. (1921) (Cardozo, J.). The rescuer is a foreseeable plaintiff so long as the rescue attempt was not reckless or wanton. Application: Carl's negligence in hosting the bonfire under dangerous conditions and failing to prevent Marcus from jumping created the peril. Nora acted reasonably in rushing to pull Marcus from the fire -- this is exactly the type of rescue attempt the doctrine contemplates. Second-degree burns to her hands are the foreseeable result of pulling someone from a fire. Nora was not reckless; she was responding to an emergency. Carl may argue that Marcus's own voluntary act was a superseding cause, but the rescue doctrine specifically holds that a tortfeasor who creates the peril is liable to rescuers even when the imperiled person was partially at fault. Nora's comparative fault, if any, appears negligible or nonexistent. Conclusion: Nora has a strong claim against Carl under the rescue doctrine and should recover her full damages. Helen v. Carl -- Negligence Per Se and Trespass Issue: Whether Carl is liable for the fire damage to Helen's property. Rule: Negligence per se applies when a defendant violates a statute or ordinance enacted to protect the class of persons to which the plaintiff belongs from the type of harm suffered. Jefferson County Ordinance 7.04 prohibits open fires within fifty feet of an adjoining property line without the neighbor's written consent. Additionally, trespass to land occurs when a defendant intentionally or negligently causes a physical invasion of another's property. Application: Helen is the adjacent landowner -- precisely the class of persons the ordinance was designed to protect. Fire spreading to neighboring property is precisely the type of harm the ordinance was designed to prevent. Carl violated the ordinance by building the fire pit only forty feet from the property line without Helen's written consent. This constitutes negligence per se, establishing both duty and breach. The fire spread from Carl's pit to Helen's property, destroying her shed and antiques, satisfying actual and proximate cause as well as damages. Helen can also assert trespass based on the physical invasion of her land by fire originating from Carl's intentional act of building the bonfire in violation of the setback requirement. Carl has no viable defense -- he cannot argue Helen was comparatively at fault, and Marcus's intervening act of jumping does not break the causal chain because the ordinance existed precisely to prevent fires from spreading regardless of how the fire might get out of control. Conclusion: Helen has an extremely strong negligence per se claim against Carl for the full $45,000 in property damage. She may also recover under trespass. Carl's Potential Cross-Claim Against Marcus Issue: Whether Carl may seek contribution from Marcus. Rule: Among joint tortfeasors, a defendant may seek contribution in proportion to each party's fault. Under comparative fault principles, a jury apportions responsibility among all parties, including the plaintiff. Application: For Helen's claim, Carl may argue that Marcus's reckless act of jumping into the fire was the event that caused the burning log to roll out. However, the ordinance violation and negligent fire placement were independent bases for liability. A jury might apportion some fault to Marcus for Helen's property damage if it finds that the fire would not have spread but for Marcus's jump, but Carl's violation of the setback ordinance provides a strong independent basis for full liability. For Nora's claim, Carl would similarly seek to attribute fault to Marcus, though the rescue doctrine limits this argument. Conclusion: Carl may pursue contribution against Marcus, but his own negligence per se and premises liability exposure will likely result in Carl bearing the majority of fault.

Issues Checklist

  • Social host liability for providing alcohol to an intoxicated guest
  • Premises liability for a dangerous condition on the land
  • Negligence per se under the fire setback ordinance as applied to both Helen and Marcus
  • Rescue doctrine protecting Nora as a foreseeable rescuer
  • Comparative fault analysis under a modified 50% bar system
  • Vicarious liability of MedFlight for pilot's negligence
  • Whether the pilot's negligence is a foreseeable intervening cause or superseding cause
  • Trespass to land from fire spreading to Helen's property

Key Rules Tested

Rescue doctrine -- danger invites rescue and the tortfeasor is liable to reasonable rescuersNegligence per se -- protected class and type of harm analysisModified comparative fault with 50% barRespondeat superior for employer vicarious liabilityForeseeable intervening cause versus superseding cause

Common Mistakes

  • Applying negligence per se to Marcus's claim without analyzing whether he falls within the protected class of the fire setback ordinance, which was designed to protect neighboring property owners
  • Failing to apply the comparative fault bar and concluding Marcus will definitely recover, when his own reckless conduct likely meets or exceeds the 50% threshold
  • Forgetting the rescue doctrine entirely and analyzing Nora's claim as a simple negligence claim without explaining why the tortfeasor owes a duty to rescuers
  • Treating the pilot's negligence as a superseding cause that cuts off Carl's liability for the spinal injury, rather than recognizing it as a foreseeable intervening cause for Carl's liability while also being an independent basis for MedFlight's liability

Grading Notes

This question tests the student's ability to handle multiple plaintiffs with different relationships to the defendant, each requiring a distinct doctrinal framework. The A answer distinguishes itself by recognizing that the fire ordinance protects neighbors (Helen) but likely not party guests (Marcus), applies the comparative fault bar rigorously to Marcus's claim, invokes the rescue doctrine for Nora, and correctly treats MedFlight's liability as independent from Carl's. The best answers will also discuss whether Carl might be liable for Marcus's spinal injury under the foreseeable intervening cause doctrine, since the need for emergency transport was created by Carl's negligence. A B answer tends to apply negligence per se indiscriminately to all plaintiffs without the protected-class analysis, overlooks the rescue doctrine, or fails to work through the comparative fault arithmetic to recognize that Marcus may be barred from recovery.

3. The Autonomous Delivery Bot

Advanced
45 min

Fact Pattern

NovaTech Industries manufactures the PathBot, a semi-autonomous sidewalk delivery robot used by MealDash, a food delivery service. The PathBot uses LIDAR sensors and machine learning algorithms to navigate sidewalks, avoid pedestrians, and deliver food orders. NovaTech's design specifications require the PathBot to yield to all pedestrians and reduce speed to two miles per hour in "high pedestrian density" zones, defined as areas where the sensors detect three or more persons within a fifteen-foot radius. MealDash programs the delivery routes and sets the speed parameters for each delivery zone. To maximize delivery speed in the competitive downtown Millbrook market, MealDash overrode the default speed settings and set the PathBot's maximum speed at eight miles per hour, double the factory default, in all zones including high-density areas. On a Saturday afternoon, the PathBot was completing a delivery on a crowded sidewalk near Millbrook University. Its sensors detected a cluster of pedestrians and initiated the high-density protocol, but because MealDash had overridden the speed settings, the robot decelerated only to six miles per hour instead of the required two. Wanda, a seventy-two-year-old retired professor, was walking with a cane and did not see the PathBot approaching from behind. The PathBot's algorithm classified Wanda as a "slow-moving obstacle" and attempted to navigate around her, but its turning radius at six miles per hour was insufficient to avoid contact. The PathBot struck Wanda's cane, causing her to lose balance and fall. She fractured her hip and struck her head on the concrete, suffering a subdural hematoma. Bystander Kevin, a twenty-eight-year-old personal trainer, immediately knelt to help Wanda. While Kevin was attending to Wanda, a second PathBot, also operated by MealDash, approached on the same sidewalk. This second PathBot's sensors malfunctioned due to a software glitch that NovaTech had identified in internal testing six months earlier but had not yet patched. The second PathBot failed to detect Kevin and Wanda on the ground and struck Kevin in the back, knocking him onto Wanda. Kevin suffered a herniated disc, and Wanda's head injury was significantly aggravated. Millbrook has adopted a municipal ordinance modeled on the Uniform Sidewalk Robot Act, which provides that "operators of autonomous delivery devices shall be strictly liable for any personal injury caused by the device during operation on public sidewalks." The ordinance defines "operator" as "the entity that deploys, controls, or directs the autonomous device in public spaces." NovaTech lobbied against this ordinance and contends it applies only to MealDash as the deploying entity, not to manufacturers.

Call of the Question

Analyze all tort claims available to Wanda and Kevin against NovaTech and MealDash. Address strict liability under both the ordinance and products liability, negligence, and any defenses. Discuss how the two PathBot incidents should be analyzed separately.

Model Answer

Wanda v. MealDash -- Strict Liability Under the Millbrook Ordinance (First PathBot) Issue: Whether MealDash is strictly liable as the "operator" of the first PathBot under the Millbrook ordinance. Rule: The Millbrook ordinance imposes strict liability on the "operator" of an autonomous delivery device for personal injuries caused during operation on public sidewalks. The ordinance defines "operator" as the entity that deploys, controls, or directs the device in public spaces. Strict liability eliminates the need to prove fault; the plaintiff need only show that the device caused injury during operation. Application: MealDash deploys the PathBots on delivery routes, programs the routes, and sets the speed parameters. MealDash exercises direct control over the device's operational behavior in public spaces. It is unambiguously an "operator" under the statutory definition. The first PathBot struck Wanda while operating on a public sidewalk, causing her hip fracture and head injury. Under the ordinance's strict liability framework, MealDash is liable regardless of whether its speed override was negligent -- the mere fact that its device caused injury during sidewalk operation triggers liability. Conclusion: MealDash is strictly liable to Wanda under the Millbrook ordinance for injuries caused by the first PathBot. Wanda v. NovaTech -- Strict Liability Under the Ordinance and Products Liability (First PathBot) Issue: Whether NovaTech qualifies as an "operator" under the ordinance and whether NovaTech is independently liable under products liability. Rule: The ordinance applies to entities that "deploy, control, or direct" autonomous devices. Manufacturers that design and sell devices but do not deploy them may argue they fall outside this definition. However, under traditional strict products liability, a manufacturer is liable for injuries caused by a defective product regardless of fault. Restatement (Third) of Torts: Products Liability Section 2. A product may be defective due to a manufacturing defect, a design defect, or inadequate warnings. A design defect exists when a reasonable alternative design would have reduced the foreseeable risk of harm. A warning defect exists when the manufacturer fails to provide adequate instructions or warnings about foreseeable risks. Application: NovaTech's argument that it is not an "operator" has merit. NovaTech manufactures the PathBot but does not deploy, control, or direct individual units on public sidewalks. MealDash makes those operational decisions. The ordinance's language most naturally reaches the deploying entity, not the upstream manufacturer. However, NovaTech faces products liability exposure. As to the first PathBot, NovaTech's design included an appropriate high-density speed protocol (two miles per hour), and it was MealDash that overrode this setting. NovaTech could argue there was no design defect because the product performed as designed; the danger arose from MealDash's modification. But a plaintiff could counter that a reasonable alternative design would have made the safety speed settings non-overridable, or at least would have required a conspicuous warning that overriding the speed limits in high-density zones would create serious pedestrian safety risks. Whether the design was defective depends on whether a reasonable manufacturer would have hardcoded the safety limits or merely made them defaults. Under risk-utility balancing, the marginal cost of making the safety protocol non-overridable is minimal compared to the foreseeable risk of serious pedestrian injury. NovaTech also had a potential duty to warn MealDash that overriding the high-density speed protocol could result in exactly this type of collision. Conclusion: NovaTech is likely not an "operator" under the ordinance. However, NovaTech faces a viable design defect claim for allowing safety-critical speed limits to be overridden and a failure-to-warn claim for not adequately warning against the dangers of overriding those limits. Wanda and Kevin v. NovaTech -- Strict Products Liability (Second PathBot) Issue: Whether NovaTech is strictly liable for the injuries caused by the second PathBot's sensor malfunction. Rule: A manufacturer is strictly liable for injuries caused by a product with a manufacturing defect (a unit that departs from its intended design) or a design defect (a foreseeable risk that a reasonable alternative design would have avoided). A manufacturer with knowledge of a defect has a post-sale duty to warn or recall. Restatement (Third) of Torts: Products Liability Section 10. Application: The second PathBot's sensor failure was caused by a software glitch that NovaTech had identified in internal testing six months earlier but had not patched. This is a powerful basis for liability on multiple theories. First, a software glitch causing sensors to fail to detect human beings on the ground is a defect rendering the product unreasonably dangerous. The glitch may constitute a manufacturing defect if it resulted from a coding error in particular units, or a design defect if it is a systemic flaw in the software architecture. Second, NovaTech's knowledge of the glitch for six months without issuing a patch or a recall creates liability under the post-sale duty to warn. A manufacturer that knows its product poses a serious risk of physical harm and fails to take reasonable steps to notify users or remedy the defect is liable for resulting injuries. The failure to patch a known sensor malfunction in a robot that operates on crowded public sidewalks is an egregious breach of the post-sale duty. Causation is straightforward: but for the sensor failure, the second PathBot would have detected Kevin and Wanda and stopped or navigated around them. Conclusion: NovaTech is strictly liable for injuries caused by the second PathBot under both defect theories and the post-sale duty to warn. Kevin v. MealDash and NovaTech -- Rescue Doctrine and Separate Analysis of Two Incidents Issue: Whether Kevin can recover for his injuries and how liability should be apportioned between the two PathBot incidents. Rule: Under the rescue doctrine, one who negligently creates a dangerous situation is liable to a person injured while reasonably attempting to rescue the imperiled party. The rescue doctrine applies to strict liability defendants as well where the defendant's activity created the peril. Each defendant is liable only for the injuries its conduct caused. Where two independent acts cause separate injuries, damages must be apportioned; where they cause a single indivisible injury, joint and several liability may apply. Application: Kevin was injured by the second PathBot while kneeling to help Wanda -- a classic rescue scenario. As to MealDash, Kevin's claim rests on the strict liability ordinance (MealDash operated the second PathBot as well) and on the argument that MealDash's deployment of PathBots on crowded sidewalks created the peril that led Kevin to render aid. As to NovaTech, the second PathBot's malfunction was caused by the known unpatched software glitch, making NovaTech liable under products liability. Kevin's herniated disc was caused by the second PathBot, so NovaTech and MealDash are jointly liable for that injury. Wanda's injuries must be separated into two categories. Her initial hip fracture and subdural hematoma were caused by the first PathBot, for which MealDash is primarily liable under the ordinance and NovaTech faces design defect exposure. Her aggravated head injury was caused by the second PathBot pushing Kevin onto her, for which NovaTech bears significant additional liability due to the known software defect. The enhanced injury doctrine applies: NovaTech and MealDash are jointly liable for the aggravation, but only NovaTech is liable for the defective sensor component. Conclusion: Kevin recovers against both MealDash and NovaTech. Wanda recovers against MealDash for all injuries under the ordinance and against NovaTech for the second PathBot injuries under products liability. NovaTech's design defect exposure for the first incident depends on whether the court finds the overridable speed setting constituted a defect. Defenses Issue: Whether any defenses are available to NovaTech or MealDash. Rule: In strict products liability, traditional contributory negligence is not a defense, but unreasonable misuse of a product may be. Assumption of risk may bar recovery if the plaintiff knowingly encountered the specific risk. Product modification by a third party may be a defense if the modification was not foreseeable. Application: NovaTech may argue that MealDash's speed override constituted product misuse or modification that was a superseding cause of Wanda's injuries from the first PathBot. This argument has force: MealDash deliberately doubled the speed and disabled a safety feature. However, if NovaTech made the speed settings easily overridable, such override was foreseeable, weakening the superseding cause argument. NovaTech has no viable misuse defense for the second PathBot, as the sensor glitch was entirely NovaTech's unpatched defect. Neither Wanda nor Kevin assumed any risk -- Wanda was simply walking on a sidewalk, and Kevin was rendering reasonable aid. Comparative fault arguments against the plaintiffs appear nonexistent on these facts. Conclusion: NovaTech has a partial defense of product modification for the first PathBot incident but no meaningful defense for the second. MealDash has no viable defense under the strict liability ordinance.

Issues Checklist

  • Strict liability under the municipal ordinance and interpretation of 'operator'
  • Strict products liability -- design defect in allowing safety overrides
  • Strict products liability -- software defect in the second PathBot's sensors
  • Post-sale duty to warn or recall for a known defect

Grading Notes

This Advanced question tests emerging tort issues involving autonomous technology alongside traditional products liability and strict liability doctrines. The A answer demonstrates sophisticated statutory interpretation of the ordinance's 'operator' definition, separately analyzes the two PathBot incidents with distinct liability theories, identifies the post-sale duty to warn as a critical issue for the second PathBot, and engages in genuine risk-utility balancing for the design defect question rather than conclusory assertions. The key differentiator between A and B answers is the treatment of NovaTech's design decision to make safety speeds overridable -- an A answer recognizes this as a nuanced design defect question requiring analysis of whether the override was foreseeable and whether hardcoding was a reasonable alternative, while a B answer either conclusorily finds a defect or exonerates NovaTech without balancing. Professors also look for precise damage apportionment between the two incidents and proper application of the rescue doctrine to Kevin's claim.

4. The Viral Malpractice Review

Advanced
45 min

Fact Pattern

Dr. Lydia Marsh is a prominent plastic surgeon in the city of Crestview. In January, Vanessa Okafor underwent rhinoplasty performed by Dr. Marsh. The surgery produced a result Vanessa found unsatisfactory -- her nose was slightly asymmetrical, though within the range of outcomes Dr. Marsh had disclosed during the pre-operative consent process. Unhappy with the outcome, Vanessa posted a detailed review on HealthGrade, a popular physician review website, under her real name. The review stated: "Dr. Marsh botched my nose job. She was probably drunk during the surgery -- I could smell something on her breath during the pre-op. She charges top dollar but delivers hack work. Find a real surgeon." Dr. Marsh had not consumed any alcohol before the surgery. She does, however, use a mouthwash containing eucalyptus oil that has a faintly medicinal smell. Dr. Marsh's practice saw a 30% decline in new patient consultations in the two months following the review. A local television reporter, Jake Trimble, saw Vanessa's review and contacted her for an interview. During a live segment on the evening news, Jake asked Vanessa: "So you believe Dr. Marsh was intoxicated during your surgery?" Vanessa responded: "All I know is what I smelled. Draw your own conclusions." Jake then stated on air: "We've also learned that Dr. Marsh is under investigation by the State Medical Board for substance abuse issues." This statement was entirely false -- no such investigation existed. Jake had received an anonymous tip he never verified. Dr. Marsh's former office manager, Ruth, had been terminated six months earlier for embezzlement. Ruth was the source of the anonymous tip to Jake. Ruth also created three fake profiles on HealthGrade, each posting fabricated negative reviews of Dr. Marsh, claiming she had "showed up impaired" to their appointments. HealthGrade's terms of service provide that the platform is not liable for user-generated content and that all disputes must be resolved through binding arbitration. Following the broadcast, Dr. Marsh lost her privileges at Crestview General Hospital pending an internal review, which eventually cleared her of any substance abuse concerns. During the three months her privileges were suspended, she lost approximately $400,000 in surgical revenue. She has also suffered severe anxiety and insomnia.

Call of the Question

Advise Dr. Marsh on all potential tort claims she may pursue against Vanessa, Jake Trimble and his employer, Ruth, and HealthGrade. Analyze the elements, potential defenses, and likely outcomes for each claim. Address any First Amendment or statutory protections that may apply.

Model Answer

Dr. Marsh v. Vanessa -- Defamation Issue: Whether Vanessa's online review constitutes actionable defamation against Dr. Marsh. Rule: Defamation requires (1) a false and defamatory statement of fact, (2) publication to a third party, (3) fault on the part of the defendant, and (4) damages. A statement of opinion is protected and not actionable, but a statement that implies undisclosed defamatory facts may be treated as a statement of fact. The distinction turns on whether a reasonable reader would understand the statement as asserting verifiable facts. Milkovich v. Lorain Journal Co. (1990). Truth is an absolute defense. For a private plaintiff, negligence as to falsity is the minimum fault standard. Application: Vanessa's review contains several distinct statements that must be analyzed separately. The statement that the surgery result was unsatisfactory and constituted "hack work" is likely protected opinion -- subjective dissatisfaction with a cosmetic outcome is the paradigmatic opinion in a consumer review context. The statement "She charges top dollar but delivers hack work" is rhetorical hyperbole. However, the statement "She was probably drunk during the surgery -- I could smell something on her breath during the pre-op" is more problematic. This statement implies a verifiable fact -- that Dr. Marsh was intoxicated while performing surgery. The word "probably" provides some hedging, but a reasonable reader could understand Vanessa as asserting that Dr. Marsh was impaired. Since Dr. Marsh was not intoxicated and the smell was eucalyptus mouthwash, the factual assertion is false. Vanessa's defense would be that she honestly reported what she perceived (the smell) and offered her subjective interpretation. The "probably" qualifier cuts in Vanessa's favor, suggesting she was sharing a suspicion rather than stating a fact. However, the totality of the review -- combined with "botched" and "drunk" -- conveys the defamatory message that Dr. Marsh is an impaired physician. As to fault, Vanessa was at least negligent in jumping from an unusual smell to an accusation of intoxication without further inquiry. Damages are presumed in many jurisdictions for defamation per se (imputing professional incompetence or criminal conduct), and Dr. Marsh can also demonstrate special damages through the 30% decline in consultations. Conclusion: Dr. Marsh has a viable defamation claim against Vanessa for the impairment accusation, though the "probably" qualifier makes the outcome uncertain. The "hack work" and dissatisfaction statements are likely protected opinion. Dr. Marsh v. Jake Trimble and His Employer -- Defamation Issue: Whether Jake's on-air statement about a fictitious Medical Board investigation is actionable defamation. Rule: A statement of fact that is false and defamatory, published to third parties, with the requisite degree of fault, gives rise to a defamation claim. For a private-figure plaintiff on a matter of public concern, the plaintiff must prove at least negligence as to the falsity of the statement. Gertz v. Robert Welch, Inc. (1974). A media defendant has a duty to exercise reasonable care in verifying statements before publication. Under respondeat superior, the employer is vicariously liable for defamatory statements made by employees within the scope of employment. Application: Jake stated on live television that Dr. Marsh was "under investigation by the State Medical Board for substance abuse issues." This is a clear, verifiable statement of fact, and it is entirely false. Jake received an anonymous tip and never verified it -- a clear failure to exercise the reasonable care required of a journalist. This is at minimum negligence, and an argument for actual malice could be made given that Jake broadcast a serious accusation from an anonymous, unverified source. The statement is defamation per se because it directly impugns Dr. Marsh's professional competence and suggests official investigation for substance abuse. Damages are substantial: loss of hospital privileges for three months, $400,000 in lost revenue, and emotional distress. Jake's employer is vicariously liable under respondeat superior because Jake made the statement during a live news broadcast in the course of his employment. The employer may also face direct liability for negligent supervision if it failed to enforce verification protocols. Dr. Marsh's status as a public figure is a threshold question. While she is described as a "prominent" surgeon, she is likely a private figure for defamation purposes because prominence in a profession does not equate to public figure status. Gertz. Even if deemed a limited-purpose public figure due to the controversy surrounding her, Jake's reckless failure to verify an anonymous tip likely satisfies the actual malice standard. Conclusion: Dr. Marsh has an exceptionally strong defamation claim against Jake and his employer. The statement was false, defamatory per se, published to a wide audience, made with at least negligence and arguably actual malice, and caused substantial damages. Dr. Marsh v. Ruth -- Defamation, Tortious Interference, and Civil Conspiracy Issue: Whether Ruth is liable for the anonymous tip and the fabricated reviews. Rule: One who provides false defamatory information to a journalist, knowing or expecting it will be published, is liable as an original publisher or republisher. Additionally, one who intentionally and improperly interferes with another's prospective economic relations through wrongful means is liable for tortious interference. Creating fake reviews under assumed identities to damage a competitor or former employer constitutes fraud and defamation. Application: Ruth, motivated by animus from her termination for embezzlement, fed Jake the false tip about the Medical Board investigation. She is liable as the originator of the defamatory falsehood. Ruth also created three fake profiles on HealthGrade posting fabricated claims that Dr. Marsh "showed up impaired" to appointments. Each fake review is an independent act of defamation -- the statements are false assertions of fact, published to the public, made with actual knowledge of their falsity (actual malice), and contributed to Dr. Marsh's reputational harm. Ruth is also liable for tortious interference with prospective economic advantage. She intentionally used wrongful means (defamation and fraud) to damage Dr. Marsh's practice, causing the loss of patients and hospital privileges. The facts also support a civil conspiracy claim if Ruth coordinated with Vanessa, though the facts do not clearly indicate coordination. Conclusion: Ruth is liable for defamation (both the anonymous tip and the fake reviews), tortious interference with prospective economic relations, and potentially fraud. Dr. Marsh v. HealthGrade -- Section 230 Immunity and Arbitration Issue: Whether HealthGrade is liable for hosting the defamatory reviews and whether the arbitration clause is enforceable. Rule: Section 230 of the Communications Decency Act provides that "no provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider." 47 U.S.C. Section 230(c)(1). This immunity protects platforms from liability for user-generated content so long as the platform did not materially contribute to the creation or development of the defamatory content. Zeran v. America Online, Inc. (4th Cir. 1997). Additionally, contractual arbitration clauses in terms of service are generally enforceable against users who agreed to them. Application: HealthGrade is an interactive computer service that hosts user-generated reviews. Under Section 230, HealthGrade is immune from defamation liability for content posted by Vanessa and Ruth, even if HealthGrade was notified of the false content and failed to remove it. The platform did not create or develop the defamatory statements. Dr. Marsh may argue that HealthGrade lost Section 230 immunity because it knew the reviews were fake (Ruth used fabricated identities) and failed to act, but courts have broadly interpreted Section 230 to protect platforms even in such circumstances. The arbitration clause is potentially enforceable against Vanessa as a user who agreed to the terms of service, but Dr. Marsh is not a party to HealthGrade's terms of service and did not agree to arbitrate. The arbitration clause in the terms binds users, not third-party plaintiffs harmed by the platform's content. Conclusion: HealthGrade is almost certainly immune under Section 230. The arbitration clause does not bind Dr. Marsh as a non-party to the terms of service. Damages Overview Dr. Marsh's recoverable damages include: special damages of approximately $400,000 in lost surgical revenue during the privilege suspension; general damages for reputational harm and the 30% decline in new consultations; emotional distress damages for anxiety and insomnia; and potentially punitive damages against Ruth (for actual malice and egregious conduct) and against Jake and his employer (if actual malice is established). Against Vanessa, punitive damages are less likely given the arguable good-faith basis for her suspicion, but remain possible if the jury finds she acted with reckless disregard for the truth.

Issues Checklist

  • Defamation -- distinguishing statements of fact from protected opinion in Vanessa's review
  • Defamation per se for imputing professional incompetence and substance abuse
  • Actual malice vs. negligence fault standard depending on public/private figure status
  • Section 230 immunity for HealthGrade as a platform hosting user-generated content
  • Republication liability for Ruth as the source of the false tip to Jake
  • Tortious interference with prospective economic advantage by Ruth
  • Respondeat superior liability of Jake's employer for on-air defamation
  • Enforceability of the arbitration clause against a non-party plaintiff

Key Rules Tested

Milkovich v. Lorain Journal -- opinion vs. implied fact distinction in defamationGertz v. Robert Welch -- private figure fault standard for defamationSection 230 of the Communications Decency Act -- platform immunity for user contentDefamation per se categories -- professional incompetence, criminal conductTortious interference with prospective economic advantageRespondeat superior for employer liability

Common Mistakes

  • Treating Vanessa's entire review as either all opinion or all fact, rather than parsing individual statements separately
  • Assuming Dr. Marsh is a public figure merely because she is described as 'prominent,' without applying the Gertz framework properly
  • Failing to address Section 230 immunity for HealthGrade and instead analyzing the platform as a traditional publisher
  • Neglecting to identify Ruth as the source of Jake's false statement and analyzing her liability only for the fake reviews

Grading Notes

This question tests intentional torts (defamation, tortious interference) alongside modern issues of internet platform liability. The A answer will carefully parse Vanessa's review statement by statement, identifying which portions are protected opinion and which assert or imply verifiable defamatory facts. It will correctly analyze the public/private figure question under Gertz rather than assuming the answer. The treatment of Section 230 is a key differentiator -- the best answers demonstrate understanding of its breadth and recognize that HealthGrade's terms of service cannot bind Dr. Marsh as a non-user. Professors particularly reward students who trace the causal chain from Ruth's anonymous tip through Jake's broadcast to the hospital suspension and lost revenue, identifying each link as actionable. A B answer typically treats the entire review as defamatory or entirely protected, fails to address Section 230, or neglects the republication/source liability of Ruth for the television broadcast.

5. The Floodgate and the Chemical Spill

Expert
60 min

Fact Pattern

Consolidated Power & Water (CPW) operates the Morrison Dam and reservoir system in Hayward County under a fifty-year federal license. The dam provides hydroelectric power and flood control for the lower Morrison River valley. In March, after a winter of historically heavy snowfall, CPW's senior hydrologist, Dr. Feng, warned CPW's operations committee that spring melt runoff projections exceeded the reservoir's capacity by fifteen percent, and recommended a controlled release of water beginning April 1 to prevent an uncontrolled overtopping of the dam. CPW's chief financial officer, Garrett, overruled Dr. Feng's recommendation because a controlled release would reduce power generation revenue during the lucrative spring energy market. Garrett directed the operations team to maintain maximum reservoir levels and to rely on the dam's emergency spillway, which had not been tested since 2011 and had a design capacity that Dr. Feng's models showed would be insufficient for the projected runoff. On April 14, the emergency spillway was overwhelmed. Water overtopped the dam and flooded the lower valley. The floodwaters reached Eastbrook, a town of twelve thousand residents approximately eight miles downstream. Among the properties damaged was the Eastbrook Chemical Works (ECW), a chemical manufacturing facility that stored large quantities of industrial solvents, including trichloroethylene (TCE), in ground-level tanks. The floodwaters breached ECW's containment walls, which had been built to withstand a "hundred-year flood" level but not the volume of water released by the dam failure. The TCE contaminated the floodwaters, which then spread through the residential neighborhoods of Eastbrook. Samuel, a homeowner in Eastbrook, suffered property damage from the flooding itself and was subsequently diagnosed with liver damage consistent with TCE exposure. His neighbor, Amara, evacuated before the floodwaters reached her home and suffered no property damage, but she was diagnosed with severe anxiety disorder after learning that TCE had contaminated the groundwater beneath her neighborhood. She fears future cancer. Groundwater testing confirmed TCE levels at three times the EPA maximum contaminant level beneath Amara's property. A class of two hundred Eastbrook homeowners has also filed suit, alleging property damage from the flooding and diminished property values due to groundwater contamination. Hayward County follows the Restatement (Second) of Torts approach to abnormally dangerous activities and applies pure comparative fault. ECW argues that the flood was an act of God that superseded any liability on its part. CPW argues that the chemical contamination was an unforeseeable consequence of the flooding and that ECW is the sole proximate cause of the toxic exposure injuries. Both defendants seek to limit their liability to only the harms directly traceable to their respective conduct.

Call of the Question

Analyze all tort claims the individual plaintiffs (Samuel and Amara) and the class of homeowners may assert against CPW and ECW. Address strict liability for abnormally dangerous activities, negligence, nuisance, proximate cause, the 'act of God' defense, emotional distress claims, and apportionment of damages between CPW and ECW.

Model Answer

Claims Against CPW -- Strict Liability for Abnormally Dangerous Activity Issue: Whether CPW's operation of the Morrison Dam and reservoir constitutes an abnormally dangerous activity subjecting CPW to strict liability for the flooding. Rule: Under the Restatement (Second) of Torts Section 520, an activity is abnormally dangerous when it creates a foreseeable and highly significant risk of harm even with the exercise of reasonable care, and the activity is not a matter of common usage. The six factors include: (a) existence of a high degree of risk, (b) likelihood that the harm will be great, (c) inability to eliminate risk by reasonable care, (d) extent to which the activity is not common, (e) inappropriateness to the location, and (f) extent to which the value to the community is outweighed by its dangerous attributes. Impounding large quantities of water has been treated as an abnormally dangerous activity in several jurisdictions. Rylands v. Fletcher (1868); Cities Service Co. v. State (Fla. 1975). Strict liability for abnormally dangerous activities extends to all harm within the scope of the abnormal risk that makes the activity dangerous. Application: CPW impounds massive quantities of water behind a dam that, if it fails, threatens a populated valley eight miles downstream. The risk of catastrophic flooding is precisely what makes dam operation abnormally dangerous. The spring runoff exceeded design capacity, and the emergency spillway -- the last line of defense -- had not been tested in over a decade and was inadequate. Even with reasonable care, the impoundment of water at this scale carries an irreducible risk of catastrophic release. The activity is not one of common usage; few entities operate large dams. While the dam provides substantial community value (power and flood control), the magnitude of the risk to a populated downstream valley supports classification as abnormally dangerous. However, CPW will argue that dam operation is a government-licensed, socially valuable activity that should not be subject to strict liability, and that the flooding resulted from a specific negligent decision (Garrett overruling Dr. Feng), not from the inherent danger of the activity. This argument has some force -- if the flood was entirely attributable to negligence, strict liability may be unnecessary. But strict liability is an alternative basis for recovery that does not require proving fault, and courts have applied it to dam operations regardless of whether specific negligence also exists. Conclusion: CPW is likely subject to strict liability for abnormally dangerous activity. Flooding of downstream communities is within the scope of the abnormal risk, satisfying the requirement that harm fall within the type of risk that makes the activity abnormally dangerous. Claims Against CPW -- Negligence Issue: Whether CPW was negligent in failing to order a controlled release of water. Rule: Negligence requires a duty of care, breach, actual and proximate causation, and damages. A dam operator owes a duty of care to downstream property owners and residents who foreseeably would be harmed by a dam failure. Breach is measured against the standard of a reasonable dam operator under the circumstances. The Learned Hand formula (B < P x L) provides a framework: liability exists where the burden of precaution is less than the probability of harm multiplied by the gravity of the loss. United States v. Carroll Towing Co. (2d Cir. 1947). Application: CPW's own hydrologist warned that runoff projections exceeded reservoir capacity by fifteen percent and recommended a controlled release beginning April 1. The burden of a controlled release was a reduction in power generation revenue -- a purely financial cost. The probability of an uncontrolled overtopping was high, as Dr. Feng's models showed the emergency spillway would be insufficient. The gravity of the potential loss was catastrophic: flooding of a town of twelve thousand. Under Learned Hand, the economic cost of reduced power revenue is vastly outweighed by the risk of catastrophic flood damage. Garrett's decision to prioritize revenue over safety is a textbook breach of duty. Actual causation is satisfied: but for the failure to conduct the controlled release, the reservoir would not have overtopped. Proximate cause is satisfied: downstream flooding from an overtopped dam is the most foreseeable consequence imaginable. Conclusion: CPW is negligent, and the negligence claim may support punitive damages given Garrett's conscious decision to prioritize profit over known safety risks. Claims Against ECW -- Strict Liability for Abnormally Dangerous Activity Issue: Whether ECW's storage of TCE constitutes an abnormally dangerous activity. Rule: Storage of large quantities of toxic chemicals in proximity to a populated area has been treated as an abnormally dangerous activity. Restatement (Second) of Torts Section 520. The relevant inquiry is whether the storage creates a high risk of serious harm that cannot be eliminated through reasonable care, particularly given the location. The scope-of-risk limitation requires that the harm be of the type that makes the activity abnormally dangerous -- here, toxic contamination. Application: ECW stored large quantities of TCE, a known toxic solvent linked to liver damage and cancer, in ground-level tanks in a town of twelve thousand. TCE contamination of the community is the precise type of harm that makes industrial solvent storage abnormally dangerous. Even with containment walls designed for a hundred-year flood, the risk of toxic release cannot be fully eliminated -- and the hundred-year flood standard proved inadequate. The inappropriateness of the location is significant: a chemical manufacturing facility storing large quantities of toxic solvents in a floodplain downstream of a dam, in proximity to residential neighborhoods, heightens the risk. ECW will argue that its containment met regulatory standards and that the flood was an extraordinary event, but strict liability does not require a showing of fault. The question is whether the activity is abnormally dangerous given the totality of the circumstances. Conclusion: ECW is likely strictly liable for the TCE contamination. The storage of toxic chemicals in a flood-prone area near residential neighborhoods satisfies the Restatement Section 520 factors. ECW's Act of God Defense Issue: Whether the flood constitutes an act of God that relieves ECW of liability. Rule: The act of God defense applies only when the harm is caused exclusively by natural forces that are extraordinary, unforeseeable, and without human contribution. If human negligence contributes to the event, the act of God defense fails. Restatement (Second) of Torts Section 522, Comment a. Application: The flood was not caused by natural forces alone. It resulted from CPW's decision to maintain maximum reservoir levels and its failure to conduct a controlled release, which was a human decision driven by financial considerations. The heavy snowfall was a natural event, but the catastrophic flooding was caused by CPW's negligent management of the dam, not by the snowfall alone. The dam failure converted a natural weather event into a man-made disaster. Because human negligence was a contributing cause of the flood, ECW cannot invoke the act of God defense. Furthermore, even if the flood were considered an act of God, a facility that stores toxic chemicals in a known floodplain arguably assumes the risk of extraordinary flood events. The hundred-year flood design standard implicitly acknowledges that more severe floods are possible. Conclusion: The act of God defense fails because the flood was substantially caused by human negligence. ECW remains liable for the TCE contamination. Proximate Cause and Apportionment Between CPW and ECW Issue: Whether CPW is the proximate cause of the TCE contamination injuries, or whether ECW's chemical release constitutes a superseding cause. Rule: A defendant is the proximate cause of harm that is a foreseeable consequence of the defendant's negligent conduct. An intervening cause is superseding only if it is unforeseeable and extraordinary. Where a defendant's negligence foreseeably brings the plaintiff into contact with a dangerous condition created by a third party, both the original tortfeasor and the third party may be proximate causes of the resulting harm. In re Kinsman Transit Co. (2d Cir. 1964). Apportionment between joint tortfeasors depends on whether the harm is divisible. Application: CPW argues that the chemical contamination was unforeseeable. This argument is weak. A dam operator that negligently floods a populated valley must anticipate that the floodwaters will encounter industrial, commercial, and residential properties and will carry whatever hazardous materials are present. Chemical facilities exist in industrial zones near rivers throughout the country. The presence of a chemical plant downstream of a dam is not extraordinary. CPW's negligent flooding foreseeably brought contaminated water into contact with the plaintiffs. CPW is therefore a proximate cause of both the flood damage and the toxic exposure injuries. ECW's storage of TCE in a flood-vulnerable location is also a proximate cause of the contamination. Both CPW and ECW are proximate causes, and the harm is indivisible -- the plaintiffs cannot separate flood damage from chemical contamination in many instances (particularly for Samuel, whose liver damage resulted from the combination of flooding and TCE exposure). Under joint and several liability principles, both defendants are liable for the full extent of the indivisible harm, with a right of contribution between them. However, some damages are divisible. Pure flood damage (structural damage to homes from water) is attributable to CPW. Chemical contamination injuries (liver damage, groundwater pollution) are attributable to both CPW and ECW. Diminished property values likely reflect both flood risk and contamination, making them indivisible. Conclusion: CPW and ECW are joint tortfeasors for the chemical contamination injuries. CPW is solely liable for pure flood damage. Apportionment of fault between CPW and ECW for the contamination injuries is a jury question. Samuel's Claims Issue: Whether Samuel can recover for both property damage and personal injury (liver damage). Application: Samuel suffered property damage from the flooding itself, for which CPW is liable under both strict liability and negligence. His liver damage from TCE exposure is compensable against both CPW (whose negligence was a proximate cause of the contamination) and ECW (whose storage of TCE is independently subject to strict liability). Samuel has strong claims against both defendants for all of his injuries. Amara's Claims -- Emotional Distress and Fear of Future Disease Issue: Whether Amara, who suffered no physical injury or property damage, can recover for emotional distress and fear of future cancer. Rule: Claims for negligent infliction of emotional distress (NIED) generally require physical impact, physical manifestation of distress, or presence in the zone of danger. A claim for fear of future disease typically requires proof of actual exposure to a toxic substance and a medically reasonable probability (not mere possibility) of developing the disease. Potter v. Firestone Tire & Rubber Co. (Cal. 1993). Some courts also require present physical injury as a predicate. Mere contamination of property, without proof of actual personal exposure and medically supported fear, is generally insufficient. Application: Amara evacuated before the floodwaters arrived and suffered no property damage or physical injury. Her claim is for emotional distress arising from fear of cancer due to groundwater contamination beneath her property. Groundwater testing confirms TCE at three times the EPA maximum contaminant level. Amara must prove actual exposure -- the fact that TCE is beneath her property does not necessarily mean she ingested or inhaled it. If she can establish exposure (through well water consumption, vapor intrusion, or soil contact), she must then present expert medical testimony that her risk of cancer is medically significant, not merely speculative. Her diagnosed anxiety disorder constitutes a severe emotional distress claim, but jurisdictions vary on whether fear of future disease is compensable without present physical injury. In a jurisdiction requiring physical impact or injury, Amara's claim is weak. In a zone-of-danger jurisdiction, she may qualify if she was in the contaminated area. In a jurisdiction following Potter, she must show subclinical exposure plus a reasonable medical probability of disease. Conclusion: Amara's emotional distress claim is viable but uncertain. It depends heavily on whether she can prove actual toxic exposure and whether the jurisdiction requires present physical injury for fear-of-future-disease claims. Class Claims and Nuisance Issue: Whether the class of homeowners can assert private nuisance and public nuisance claims. Rule: A private nuisance is a substantial and unreasonable interference with the use and enjoyment of land. A public nuisance is an unreasonable interference with a right common to the general public. An individual may recover for a public nuisance only by showing special damages different in kind from those suffered by the general public. Application: The class of two hundred homeowners has strong private nuisance claims against both CPW and ECW. The flooding and TCE contamination constitute a substantial and unreasonable interference with the use and enjoyment of their land. Diminished property values reflect the ongoing interference. A public nuisance claim is also viable because the groundwater contamination affects the entire community's water supply and environmental safety. The individual homeowners suffer special damages (property damage, diminished home values) different in kind from the general public's interest in clean groundwater. Both strict liability and negligence claims are also available to the class on the same theories discussed above. The class can recover property damage from flooding against CPW and diminished property values from contamination against both CPW and ECW. Conclusion: The class has strong claims in negligence, strict liability, and nuisance against both CPW and ECW. The primary litigation battleground will be apportionment of damages between flood damage (CPW) and contamination damage (both defendants).

Common Mistakes

  • Accepting CPW's argument that chemical contamination was unforeseeable without analyzing whether industrial facilities in a downstream town are a foreseeable feature of the landscape

  • Failing to distinguish between divisible damages (pure flood damage vs. contamination damage) and indivisible damages when apportioning liability

Grading Notes

This Expert-level question is a complex multi-party environmental tort problem that tests the student's ability to juggle multiple liability theories simultaneously while maintaining analytical precision. The A answer demonstrates mastery of the Restatement Section 520 factors by applying them separately to both the dam and the chemical storage, rather than conclusorily labeling both as abnormally dangerous. It recognizes the act of God defense and dismantles it by identifying the human contribution. The most sophisticated answers will grapple with the proximate cause chain linking CPW's negligence to the chemical contamination -- this is the central analytical challenge of the question, and the best students will cite Kinsman Transit or Wagon Mound to support their analysis of foreseeability. Amara's claim is a deliberate trap: many students will either grant her full recovery or dismiss her claim entirely, when the correct analysis requires careful attention to the actual-exposure requirement and the jurisdiction's approach to fear-of-future-disease claims. Professors also look for precise damage apportionment -- the A answer identifies which damages are divisible (pure flood damage to CPW, pure contamination to both) and which are indivisible (diminished property values reflecting both risks). A B answer typically applies strict liability conclusorily, fails to engage with the act of God defense or proximate cause debate, or treats Amara identically to Samuel without recognizing the distinct doctrinal hurdles she faces.
