A fundamental legal principle determining that the law of the jurisdiction where an event occurs (e.g., a contract is made, property is located, or a tort is committed) governs the legal consequences of that event. Often used in conflict of laws (private international law) to resolve which jurisdiction's law should apply to a case.
