Section 67: Meaning of “United Kingdom national”, “UK resident” and “person subject to UK service jurisdiction”
108.Subsection (3) defines a “person subject to UK Service jurisdiction” by reference to the various Service Discipline Acts. Such persons are within the jurisdiction of Service courts and may be tried for offences under Service law, wherever they may be in the world at the time the offence is committed. This mainly involves Service personnel but may also, in the circumstances specified in the Service Discipline Acts, include certain categories of civilians, such as families and certain civilians who carry out support facilities for the Armed Forces.
