Jurisdiction, p. 101ff. The power of a state to exercise jurisdiction is not unlimited. National jurisdiction is divided into legislative jurisdiction, also called prescriptive; adjudicative; or executive (the latter two are sometimes called enforcement jurisdiction).
The state may assert jurisdiction over a person or entity on the basis of nationality, even if the person or entity happens to be outside the state of citizenship.
If you are a US citizen, which US laws apply to you, because you are a US citizen, even when you are outside the US? If you are citizen of another country, which laws of your country apply to you even when you are outside your own country?
These judges thought the Court should have ruled on the legitimacy of Belgium’s jurisdiction before considering the issue of immunity and noted that the arrest warrant must have been based on universal jurisdiction as the Belgian legislation permits the assertion of universal jurisdiction for serious violations of international humanitarian law (the laws of war) without any connection to Belgium. Other states’ legislation for prosecuting war crimes requires some connection with the forum or indicates which treaty must have been violated. Case law also requires a connection with the forum or a treaty violation. The Geneva Conventions require prosecution or extradition of persons found within their territory accused of grave violations of the Conventions.
