[F1Article 12 U.K.

1. In exceptional circumstances, where duly justified by an appropriate analysis by the Commission and in order to avoid a serious and unacceptable threat to maritime safety or incompatibility with Union maritime legislation, the Commission is empowered to adopt delegated acts in accordance with Article 12a, amending this Directive in order not to apply, for the purposes of this Directive, an amendment to the international instruments referred to in Article 2.

2. Those delegated acts shall be adopted at least 3 months before the expiration of the period established internationally for the tacit acceptance of the amendment concerned or the envisaged date for the entry into force of said amendment. In the period preceding the entry into force of such delegated act, Member States shall refrain from any initiative intended to integrate the amendment in national legislation or to apply the amendment to the international instrument concerned.]
