- For an article concerning the powers of courts and public authority see, Jurisdiction.
A jurisdiction is an area with a set of laws under the control of a system of courts or government entity which are different to neighbouring areas.
Each state in a federal state such as Australia, Germany and the United States forms a separate jurisdiction. However sometimes certain laws in a federal state are uniform across the constituent states and enforced by a set of federal courts; with a result that the federal state forms a single jurisdiction for that purpose.
Unitary states are usually single jurisdictions, but the United Kingdom is a notable exception; it has three separate jurisdictions due to its three separate legal systems.
