Jurisdiction (from the Latin words jus = law, dictio = statement) is an exercise of judicial or other authority over legal matters, or definition of who falls within its scope and girth.
Under Czech law, in determining which courts hear and decide a particular thing, the terms judicial or official powers and jurisdiction are used.
In international law, the term jurisdiction usually means individual states (based on their sovereignty). In the case of federation it can also be a single province. There are also countries like the United Kingdom, where there are four countries and three different jurisdictions (England and Wales, Scotland, Northern Ireland). In international law, there are two types of jurisdiction, territorial (each is subject to the power of the state where they reside) and personal (citizen subject to the jurisdiction of the home country, even if not exactly in its territory).
The jurisdiction can also be spoken on in case of international organizations (eg the jurisdiction of the International Criminal Court) and multinational organizations (eg the jurisdiction of the European Union).
