6.—(1) A person shall not be returned under Part III of this Act, or committed or kept in custody for the purposes of return, if it appears to an appropriate authority—
(a)that the offence of which that person is accused or was convicted is an offence of a political character;
(b)that it is an offence under military law which is not also an offence under the general criminal law;
(c)that the request for his return (though purporting to be made on account of an extradition crime) is in fact made for the purpose of prosecuting or punishing him on account of his race, religion, nationality or political opinions; or
(d)that he might, if returned, be prejudiced at his trial or punished, detained or restricted in his personal liberty by reason of his race, religion, nationality or political opinions.
(3) A person accused of an offence shall not be returned, or committed or kept in custody for the purposes of return, if it appears to an appropriate authority that if charged with that offence in the Territory he would be entitled to be discharged under any rule of law relating to previous acquittal or conviction.
(4) A person shall not be returned to a designated Commonwealth country or to a colony or to the Republic of Ireland, or committed or kept in custody for the purposes of such return, unless provision is made by the relevant law, or by an arrangement made with the relevant Commonwealth country or colony or the Republic of Ireland, for securing that he will not, unless he has first had an opportunity to leave it, be dealt with there for or in respect of any offence committed before his return to it other than—
(a)the offence in respect of which his return is ordered;
(b)an offence, other than an offence excluded by subsection (5) below, which is disclosed by the facts in respect of which his return was ordered; or
