Jurisdiction

Jurisdiction (from Latin 'law' and 'speech' or 'declaration') is the legal term for the legal authority held by a legal entity to enact justice. Jurisdiction is rarely claimed to be complete: rather it is limited for example by geography, subject matter, or other factor. It is only within the scope (inside the limits) of such jurisdiction that, for example, the parties to a dispute have standing to bring the matter (a legal question) before a judge, who has power (or 'jurisdiction') to decide it authoritatively.

A "jurisdiction" can also be understood as a category name for any separate polity legally constituted as such — for any government with legislative and other legal power over a particular territory, whether that area is a nation state or some smaller region. Thus, Australia, Arizona, North Yorkshire and New York City are each "a jurisdiction". In federations like the United States, jurisdiction in this polity sense applies at multiple levels (e.g., local, state, and national/federal).

Jurisdiction draws its substance from international law, conflict of laws, constitutional law, and is often thought to include the powers of the executive and legislative branches of government to pursue policies and allocate resources so as to best serve the needs of society. Provided by Wikipedia
