The following procedure has been formulated pursuant to Article 8 of the Montreal Protocol. It shall apply without prejudice to the operation of the settlement of disputes procedure laid down in Article 11 of the Vienna Convention.

1. If one or more Parties have reservations regarding another Party's implementation of its obligations under the Protocol, those concerns may be addressed in writing to the Secretariat. Such a submission shall be supported by corroborating information.

2. The Secretariat shall, within two weeks of its receiving a submission, send a copy of that submission to the Party whose implementation of a particular provision of the Protocol is at issue. Any reply and information in support thereof are to be submitted to the Secretariat and to the Parties involved within three months of the date of the despatch or such longer period as the circumstances of any particular case may require. If the Secretariat has not received a reply from the Party three months after sending it the original submission, the Secretariat shall send a reminder to the Party that it has yet to provide its reply. The Secretariat shall, as soon as the reply and information from the Party are available, but not later than six months after receiving the submission, transmit the submission, the reply and the information, if any, provided by the Parties to the Implementation Committee referred to in paragraph 5, which shall consider the matter as soon as practicable.
