Q1: What area of law does Trimarco v. Klein primarily address?
Torts
Q2: What was the central legal issue in Trimarco v. Klein?
Whether proof of a well-defined and widely accepted custom to use safety glazing in bathtub enclosures, together with evidence that the landlord failed to follow that custom, is admissible and sufficient to support a finding that the landlord breached the duty of reasonable care and had constructive notice of the hazard posed by ordinary plate glass.
Q3: What rule did the court apply?
In negligence actions, evidence of industry custom and usage is admissible as probative of reasonable care. When a customary practice is well established and general in the relevant community, a jury may infer negligence from a defendant's deviation from that practice, provided the jury also finds the custom itself to be reasonable under the circumstances. Compliance with custom does not automatically establish due care, and noncompliance is not conclusive of negligence. In premises liability, a landlord may be liable for a dangerous condition on the premises if the landlord created it or had actual or constructive notice of it; widespread custom, and the recognition it reflects of a known hazard and feasible safety measures, can support constructive notice. Statutes or codes adopted after an installation are not retroactive mandates but may be considered as some evidence bearing on the existence and reasonableness of the practice and the recognition of the hazard.
Q4: What was the court's holding?
The Court of Appeals reversed the Appellate Division and held that the plaintiff's evidence of a long-standing, general custom to use safety glazing in bathtub enclosures, and the landlord's failure to adhere to that practice, was properly admitted and sufficient to create a jury question on negligence and constructive notice. The dismissal of the complaint was error.
Q5: Why is Trimarco v. Klein significant?
Trimarco clarifies that custom and usage are potent, but not definitive, tools in negligence litigation. It teaches students how to marshal custom evidence to define reasonable care, to argue constructive notice in premises cases, and to situate later-enacted statutes as corroborative rather than retroactive mandates. The case also balances deference to industry practice with the central torts principle that the jury ultimately decides what reasonable care requires.
