The Ministerial Conference upon the request of the Members parties to a trade agreement, may decide exclusively by consensus to add that agreement to Annex 4. The Ministerial Conference, upon the request of the Members parties to a Plurilateral Trade Agreement, may decide to delete that Agreement from Annex 4.
The Ministerial Conference and the General Council shall have the exclusive authority to adopt interpretations of this Agreement and of the Multilateral Trade Agreements. In the case of an interpretation of a Multilateral Trade Agreement in Annex 1, they shall exercise their authority on the basis of a recommendation by the Council overseeing the functioning of that Agreement. The decision to adopt an interpretation shall be taken by a three-fourths majority of the Members. This paragraph shall not be used in a manner that would undermine the amendment provisions in Article X.
