Trespass to chattels: The tort of “trespass to chattels” occurs when the defendant intentionally interferes with the plaintiff’s use or possession of a “chattel” (i.e., a piece of personal property, such as a car or a diamond ring).

Loss of possession: The tort occurs when D interferes with the owner’s “possession” of the good, even if it is a brief interference (e.g., an unauthorized “borrowing” of the item, such as taking a neighbor’s lawnmower for 10 minutes, or taking his car for a two-block joy ride).
