Section 9: Detention by Nigerian service authorities of sentenced members of visiting forces

(1) Where any sentence of imprisonment or detention has been passed in Nigeria by a service court of a country to which this section applies upon a person who immediately before the sentence was passed was a member of a visiting force of that country, the Minister, if so requested by the appropriate authority of that country, may issue a warrant in writing authorising any Nigerian service authority to detain that person in custody for such period not exceeding the term of his sentence as may be specified in the warrant.
(2) A person in respect of whom a warrant has been issued under this section may, in accordance therewith, be detained by any Nigerian service authority in like manner as if he were a member of the home forces liable to be detained in custody in pursuance of a corresponding sentence passed by a Nigerian service court.
(3) For the purposes of any proceedings arising out of the foregoing provisions of this section, a certificate issued by or on behalf of the Minister, stating that a request has been made for the issue of a warrant under this section in respect of a person named in the certificate shall be sufficient evidence, unless the contrary is proved, of the facts stated therein.
