Commonwealth are serving together; with respect to the attachment of members of one such force to another such force, and with respect to deserters from such forces." During World War II, the Allied Forces Act 1940 enabled visiting Allied forces to conduct courts martial, but did not provide immunity from ordinary criminal law. There was a single exception, as the United States of America (Visiting Forces) Act 1942 gave members of the United States naval and military forces immunity in United Kingdom courts. That remained the position until the aforementioned acts were repealed by the Visiting Forces Act 1952. The Visiting Forces Act 1952 was passed to incorporate the provisions of the NATO Status of Forces Agreement into United Kingdom law. SOFA provides a basis for a mutual and reciprocal system of exemptions, immunities and privileges for visiting forces when exercising or stationed in a host country. A major feature of SOFA, which is implemented by the 1952 Act, is the question of jurisdiction for dealing with offences committed by visiting servicemen, civil servants accompanying a force, dependents and contractors. Its main provision is the agreement that the visiting force will retain jurisdiction for its people, which applies equally to United States personnel based in the United Kingdom and British forces serving in NATO countries, Commonwealth countries and, more recently, those countries that have signed up to the NATO partnership for peace. Usually, the service authorities for the visiting force member alleged to have committed an offence and the United Kingdom authorities will be able to agree which jurisdiction is appropriate to deal with the case. If agreement is not reached the decision as to jurisdiction will be referred to the Crown Prosecution Service. Where United Kingdom jurisdiction is appropriate the visiting forces case will normally be dealt with locally unless other criteria require the case to be dealt with by Crown Prosecution Service headquarters. Section 1 of the Visiting Forces Act 1952 contains a list of countries to which the act applies. Subsection 2 of Section 1, along with Subsection 2 of Section 15 provide the authority and a means for extending this list. Visiting Forces (Designation) Order 1997 and 1998 extended this list by designation additional countries. Anguilla, the Cayman Islands, Montserrat and the Virgin Islands Statutory Instrument 1990 No. 24 extends the provisions of the British Visiting Forces Act 1952 to these territories.
