A jurisdiction is an area with a set of laws and under the control of a system of courts or government entity that is different from neighbouring areas.
However, certain laws in a federal state are sometimes uniform across the constituent states and enforced by a set of federal courts; with the result that the federal state forms a single jurisdiction for that purpose.
[5][6] Unitary state are usually single jurisdictions, but the United Kingdom is a notable exception since it has three separate jurisdictions because of its three separate legal systems.
Also, China has the separate jurisdictions of Hong Kong and Macao.
