CONSIDERING that the provisions of this Protocol should ensure the proper implementation and application of the relevant provisions of EU law with regard to the basic sovereign territories after the UK`s withdrawal from the EU; In the event of disagreement between the Union and the United Kingdom over the reasonable period of time to comply with the arbitration panel`s decision, the applicant asks in writing to the arbitration panel to establish the duration of the reasonable period of time within forty days of the respondent`s notification in paragraph 1. This request is notified to the respondent at the same time. The arbitration panel notifies the EU and the United Kingdom of its decision on the deadline for compliance within 40 days of filing the application. NOTE that, although EU law is applicable in the United Kingdom and the United Kingdom during the transitional period, it is important for the United Kingdom to take steps to prepare and implement new international agreements; Including in areas under the EU`s exclusive jurisdiction, provided that these agreements do not enter into force or apply during this period, if the Union does not authorise their approval, with the aim of setting the terms of the Uk`s exit from the EU and Euratom taking into account the framework of their future relations, this paragraph applies, unless an agreement within the meaning of Article 184 is replaced by this paragraph or applicable, is set. “custody rights”: custody of children within the meaning of Article 2 of Regulation (EC) No. 2201/2003 (6), including agreement obtained through termination, legal protection or valid agreement. The United Kingdom ensures that all specific obligations arising from Community agreements with third countries or international organisations concerning nuclear equipment, nuclear materials or other nuclear elements present in the United Kingdom at the end of the transition period are fulfilled, or to conclude, by other means, appropriate arrangements in agreement with the third country or an international organisation concerned. The arbitration panel, in agreement with the parties, may decide not to hold a hearing. On an exceptional basis, the Union invites the United Kingdom to participate, in the context of the EU delegation, in meetings or meetings of these bodies, where the Union considers that the UK`s presence is necessary and is in the interests of the Union, particularly for the effective implementation of these agreements during the transitional period; this presence is only permitted if the participation of Member States is authorised by the existing agreements. WITH REGARD TO THE IMPLEMENTATION OF APPROPRIATE MEASURES TO ACHIEVE THE OBJECTIVES OF THE REGIMES UNDER PROTOCOL 3 AFTER THE UK`S WITHDRAWAL FROM THE EU, 2. In the event that the EU and the United Kingdom reach agreement on their future relations in the areas of the common foreign and security policy and the common security and defence policy that comes into force during the transitional period, Chapter V of the TUE and the acts adopted on the basis of these provisions no longer apply to the United Kingdom from the date of implementation of this agreement.
