51B.— (1) On application made in accordance with section 51(1) or 51A(2) and without prejudice to section 3, the High Court shall refuse to make a confiscation co-operation order in respect of an external confiscation order, or shall make an order refusing the execution of an external confiscation order made by or on behalf of a court in a designated state that is a member state, as the case may be, if—

(a) subject to subsection (4), the conduct which resulted in the making of the external confiscation order is not an offence to which the relevant international instrument relates,

(b) F42[where the designated state concerned is a state other than the United Kingdom, there is immunity or privilege] under the law of the State which makes it impossible to make the confiscation co-operation order or execute the external confiscation order, as the case may be,

(c) it is immediately clear from the information provided in a certificate that compliance with the external confiscation order in relation to the offence that resulted in the making of that order would infringe the ne bis in idem principle,

(d) the defendant did not appear in person at the trial resulting in the external confiscation order, unless the certificate from the court in the designated state concerned states that—

(i) he or she was notified of the time when, and place at which, the proceedings were to take place, or he or she was otherwise aware of the scheduled proceedings, and he or she was informed that an external confiscation order could be made even if he or she did not appear,

(ii) he or she was aware of the proceedings concerned and was represented at those proceedings by a lawyer whom he or she has appointed,

(iii) after having been served with the external confiscation order and expressly informed of his or her right to a retrial or an appeal in which he or she would have been able to participate and which could have led to the original decision being reversed, he or she—

(I) expressly stated that he or she did not contest the external confiscation order, or

(II) did not request the retrial or appeal within the time limit for exercising that right,

or

(iv) in a case where he or she was not personally served with the external confiscation order, an undertaking has been given by the designated state concerned that he or she will be personally served with the external confiscation order without delay and will be expressly informed of his or her right to a retrial or an appeal in which he or she will be able to participate and which could lead to a reversal of the order, and of the time limit for exercising that right,

(e) F42[where the designated state concerned is a state other than the United Kingdom, the criminal conduct concerned] was either committed outside the territory of the designated state concerned or committed wholly or partly in the State, or

(f) the enforcement of the confiscation co-operation order, or the execution of the external confiscation order, as the case may be, is statute barred.

(2) Where the copy of the external confiscation order is not accompanied by the documents required under section 50(2), or is incomplete or does not correspond to the external confiscation order, the High Court—

(a) may permit the certified copy of the order, or a completed or corrected certified copy of the order, to be produced by or on behalf of the court concerned in accordance with a specified deadline, or

(b) shall refuse to make a confiscation co-operation order or, as the case may be, to execute the external confiscation order, unless it is satisfied, by the production of an equivalent document or otherwise, that the information provided by or on behalf of the court concerned is sufficient.

(3) F42[Where the designated state concerned is a state other than the United Kingdom, the High Court] shall not make a confiscation co-operation order or, as the case may be, shall make an order refusing the execution of the external confiscation order if it is satisfied that the rights of any person holding an interest in the property the subject of the external confiscation order concerned make it impossible to execute that order.

(4) Where an external confiscation order is transmitted by or on behalf of a court in a designated state that is a member state, and the offence that resulted in the making of the order is an offence referred to in Article 6(1) of the 2006 Framework Decision punishable in that designated state by a maximum term of imprisonment of not less than 3 years, the High Court shall not make an order refusing the execution of the external confiscation order solely on the ground that the conduct constituting the offence that resulted in the making of that external confiscation order does not constitute an offence under the law of the State.]
