of the US judiciary and executive. Under this doctrine, US courts exercise restraint in not
questioning the validity of the taking of property abroad by a foreign state, even if it may have been
done in breach of international law, unless there is a treaty with the foreign state governing the
matter.

The approach is similar to that of non-justiciability.

In 2002, the European Court of Human Rights ruled that in the present state of international law
state immunity is not incompatible with human rights.

Sources of the law on state immunity
It may be some time before the UN Convention enters into force. It is not clear to what extent parts
of it reflect customary international law or represent progressive development. Nevertheless, the
Convention, being the only universal treaty on the subject, represents a good basis from which to
examine what the customary law is or, at least, may be. The Convention will therefore be the focus
of the following pages, even though in parts it is rather lacking in clarity and certainty, and the law
of state immunity will vary from state to state.
The Convention will be discussed along with the only other treaty on the subject, the European
Convention on State Immunity 1972 (in this chapter, the ‘European Convention’),
14
since Article 26
of the UN Convention provides that nothing in it shall affect rights and obligations under existing
treaties on state immunity. Although the European Convention is much concerned with reciprocal
enforcement of judgments by the parties to it (only eight), it has been influential in the formulation
of legislation by other states. Two leading pieces of legislation will examined: the State Immunity
Act 1978 (in this chapter, the ‘UK Act’),
15
which largely follows the European Convention, and the
Foreign Sovereign Immunities

has been modelled on the Act, and the UN Convention has borrowed several of its provisions. The Act
does not apply to visiting forces (s. 16(2)) to which only the common law applies: see Holland v. Lampen-
