A person's extradition to a category 2 territory is barred by reason of hostage-taking considerations if (and only if) the territory is a party to the Hostage-taking Convention and it appears that—
if extradited he might be prejudiced at his trial because communication between him and the appropriate authorities would not be possible, and
the act or omission constituting the extradition offence also constitutes an offence under section 1 of the Taking of Hostages Act 1982 (c. 28) or an attempt to commit such an offence.
The appropriate authorities are the authorities of the territory which are entitled to exercise rights of protection in relation to him.
A certificate issued by the Secretary of State that a territory is a party to the Hostage-taking Convention is conclusive evidence of that fact for the purposes of subsection (1).
The Hostage-taking Convention is the International Convention against the Taking of Hostages opened for signature at New York on 18 December 1979.
