Under Article 5 of the Framework Decision, entitled ‘Guarantees to be given by the issuing Member State in particular cases’: ‘The execution of the European arrest warrant by the executing judicial authority may, by the law of the executing Member State, be subject to the following conditions: … (2) if the offence on the basis of which the European arrest warrant has been issued is punishable by custodial life sentence or life-time detention order, the execution of the said arrest warrant may be subject to the condition that the issuing Member State has provisions in its legal system for a review of the penalty or measure imposed, on request or at the latest after 20 years, or for the application of measures of clemency to which the person is entitled to apply for under the law or practice of the issuing Member State, aiming at a non-execution of such penalty or measure; (3) where a person who is the subject of a European arrest warrant for the purposes of prosecution is a national or resident of the executing Member State, surrender may be subject to the condition that the person, after being heard, is returned to the executing Member State in order to serve there the custodial sentence or detention order passed against him in the issuing Member State.’ 12 Article 6 of the Framework Decision, entitled ‘Determination of the competent judicial authorities’, provides in paragraph 1: ‘The issuing judicial authority shall be the judicial authority of the issuing Member State which is competent to issue a European arrest warrant by virtue of the law of that State.’ 13 Article 7 of the Framework Decision, entitled ‘Recourse to the central authority’, provides in paragraph 1: ‘Each Member State may designate a central authority or, when its legal system so provides, more than one central authority to assist the competent judicial authorities.’ 14 Article 15 of the Framework Decision, ‘Surrender decision’, reads as follows: ‘1.
