The Fox Chase Jurisprudence

It seems absurd that a landmark ruling on modern property law should hinge on a dead fox, but in 1805, the New York Supreme Court of Judicature found itself grappling with exactly that. Lodowick Post had been actively hunting a wild fox with his hounds, tracking the animal through the open beach. In the middle of the chase, Jesse Pierson intercepted the animal, killed it, and took it away. Post sued for trespass, setting off a legal battle over a remarkably strange question: does merely chasing a wild animal give you a legal right to it?

The court answered with a definitive no. Writing for the majority, Justice Tompkins ruled that hot pursuit alone does not establish property. To claim ownership of a creature of the wild, you have to actually catch it, or at least mortally wound it so that escape is impossible. Merely running after something, no matter how close you are to the finish line, leaves it up for grabs.

The logic behind the decision was practical rather than sentimental. The judges were terrified of opening the floodgates to endless, chaotic disputes. If pursuit alone constituted ownership, where would the law draw the line? Every frustrated hunter in the state would be hauling their rivals into court to argue over the fuzzy boundaries of a chase.

To solve this, the court reached backward across the centuries, drawing on ancient legal treatises by Justinian, Fleta, and Bracton to anchor their decision in classical jurisprudence. They traded the messy reality of human effort for a bright-line rule: possession is nine-tenths of the law, and the other tenth is a corpse.
