Paragraph 11 Evidence.
In any proceedings under this Act, including proceedings on an application for habeas corpus in respect of a person in custody thereunder—
a document, duly authenticated, which purports to set out evidence given on oath in the United Kingdom or a designated Commonwealth country or the Republic of Ireland or a United Kingdom dependency (other than Anguilla) shall be admissible as evidence of the matters stated therein;
a document, duly authenticated, which purports to have been received in evidence, or to be a copy of a document so received, in any proceeding in any such country or dependency shall be admissible in evidence;
a document, duly authenticated, which certifies that a person was convicted on a date specified in the document of an offence against the law of, or of a part of, any such country or dependency shall be admissible as evidence of the fact and date of the conviction.
A document shall be deemed to be duly authenticated for the purposes of this section—
in the case of a document purporting to set out evidence given as aforesaid, if the document purports to be certified by a judge or magistrate or officer in or of the country or dependency in question to be the original document containing or recording that evidence or a true copy of such a document;
in the case of a document which purports to have been received in evidence as aforesaid or to be a copy of a document so received, if the document purports to be certified as aforesaid to have been, or to be a true copy of a document which has been, so received;
in the case of a document which certifies that a person was convicted as aforesaid, if the document purports to be certified as aforesaid,
and in any such case the document is authenticated either by the oath of a witness or by the official seal of the Secretary of State or of a Minister of the designated Commonwealth country or of the Republic of Ireland or of the Governor or a Minister, secretary or other officer administering a department of the Government of the dependency, as the case may be.
In this section “oath” includes affirmation or declaration; and nothing in this section shall prejudice the admission in evidence of any document which is admissible in evidence apart from this section.
