Study notes for Herrin v. Sutherland: professor notes, cold call prep, exam angles, and memory aids.

Intentionally discharging a firearm so that its blast and shot pass through the airspace above another's land constitutes trespass.
Professor Notes

In Herrin v. Sutherland, the Montana Supreme Court addressed a significant issue in property law regarding the extent of a landowner's rights to the airspace above their land. The court emphasized the importance of the right to exclude others from airspace, which is a critical aspect of possessory interest in property. By holding that the discharge of a shotgun in such a manner that its effects intrude into the airspace of another's land constitutes trespass, the case reinforced the principle that property rights extend not only to the earth but also to the space above it. Additionally, the decision establishes a precedent where intentional actions causing disruption, even without direct physical impact to the land, can result in liability for trespass.

When discussing this case, it is crucial to consider contemporary implications, particularly how it relates to air traffic and the use of drones, where the boundaries of airspace ownership are increasingly blurred. The ruling illustrates how traditional property rights can adapt to modern technologies and changing societal contexts.

Cold Call Prep
  1. 1The court held that Sutherland's actions constituted trespass because they directly invaded Herrin's airspace.
  2. 2The key issue was whether airspace is a protected property interest similar to land itself.
  3. 3The ruling emphasizes the intentionality behind the act of discharging the firearm.
  4. 4Consider how this case contrasts with invasions not directly causing physical damage.
  5. 5Discuss distinctions between airspace claims and those pertaining to physical encroachments.

Distinguish From
CaseDistinction
Smith v. MarylandIn Smith v. Maryland, the court ruled that a mere passing of aircraft through airspace did not amount to trespass, as it did not interfere with the landowner's possessory rights.
U.S. v. CausbyIn U.S. v. Causby, the focus was on the impact of low-flying military aircraft on the use of land rather than a direct invasion, illustrating a different context for airspace rights.
Policy Arguments

For the Rule
