Territorial Principle

Territorial Principle

Definition

The rule that a state has jurisdiction over acts committed entirely outside the state if the actor intended to produce, and did produce, detrimental effects within the state. The Supreme Court established the detrimental-effects test in Strassheim v. Daily, 221 U.S. 280 (1911). Most jurisdictions today have territorial-jurisdiction statutes that apply similar tests focusing on the harm caused within the state.
