Exchange of letters of January 18 and March 14, 1977 relating to Article 36, paragraph 3, Regulation (EEC) 1408/71 (agreement on reimbursement or waiver of reimbursement of material expenses covered by Title III, Chapter 1, Regulation (EEC) 1408/71. 1408/71) amended by the exchange of letters of 4 May and 23 July 1982 (agreement on reimbursement of costs in accordance with Article 22, paragraph 1, paragraph a), Regulation (EEC) No. 1408/71) The Union and the United Kingdom make efforts in good faith and in full compliance with their respective legal systems; take the necessary steps to quickly negotiate the agreements on their future relations covered in the political declaration of 17 October 2019 and implement the appropriate procedures for the ratification or conclusion of these agreements, to ensure that these agreements apply as much as possible from the end of the transition period. The obligations arising from the Member States acting on their behalf by the Union or the Member States acting jointly, to the extent that they relate to the trade in goods between the Union and third countries, may be amended, rejected or proposed by the House of Commons with regard to the changes made to the lords. If Members accept all amendments, the law can be prepared for royal approval and become law. If there are outstanding areas, these issues must be left to the Lords for further consideration. This process (also known as ping-pong) continues until a full agreement is reached or the law is blocked. Considering that the basic sovereign territories should remain part of the Union`s customs territory after the UK`s withdrawal from the Eu, the Court of Arbitration may decide, in agreement with the contracting parties, not to hold a hearing. The result is the dilemma that British constitutional rights defenders are familiar with and which has been the subject of much discussion during the UK`s lifetime membership of the EU.
