Pierson v Post- (Supreme Court of Judicature of New York, 1805)

Biggs Darklighter is flying his T-16 down Beggar's Canyon, an unowned plot of land on Tatooine. Biggs locates and begins pursuing a wild womp rat. Just as he is about to corner the womp rat in a corner of the canyon and fire upon it, Luke Skywalker bullseyes the womp rat from his T-16 and makes off with it. Biggs files suit, claiming that Luke stole his womp rat. Looking to the logic of earlier authors, the council rules that even though Biggs was in pursuit, intent to possess and pursuit alone are not enough to convert the womp rat into property. Luke's intention of possession was made real by the act of mortally wounding the womp rat, sufficiently converting the womp rat into his property.
