Article 1
Coverage and Application
2.The rules and procedures of this Understanding shall apply subject to such special or additional rules and procedures on dispute settlement contained in the covered agreements as are identified in Appendix 2 to this Understanding. To the extent that there is a difference between the rules and procedures of this Understanding and the special or additional rules and procedures set forth in Appendix 2, the special or additional rules and procedures in Appendix 2 shall prevail. In disputes involving rules and procedures under more than one covered agreement, if there is a conflict between special or additional rules and procedures of such agreements under review, and where the parties to the dispute cannot agree on rules and procedures within 20 days of the establishment of the panel, the Chairman of the Dispute Settlement Body provided for in paragraph 1 of Article 2 （referred to in this Understanding as the “DSB”）, in consultation with the parties to the dispute, shall determine the rules and procedures to be followed within 10 days after a request by either Member. The Chairman shall be guided by the principle that special or additional rules and procedures should be used where possible, and the rules and procedures set out in this Understanding should be used to the extent necessary to avoid conflict.
