It starts out by saying that the joint commission consists of the cabinet level representatives of the parties or their designees; hence, clause 10 makes the Minister of International Trade the “principal representative” of Canada on the commission. It goes on to say in paragraph 2 that the commission shall supervise the implementation of the agreement; review the general functioning of the agreement; assess the outcomes of the application of the agreement; oversee the further elaboration of the agreement; supervise the work of all committees, working groups, and country coordinators established under the agreement; approve model rules of procedure—and that's for dispute settlement; and consider any other matter that may affect the operation of the agreement.
Then it goes on to permit the commission to do additional things, in paragraph 3, including adopting interpretive decisions concerning the agreement that are binding on dispute settlement panels. That's the same function that exists and has been used in NAFTA in the case of chapter 11.
Then, perhaps of interest to you, is that it can seek the advice of non-governmental persons or groups. The commission does have the power to do that. It can also take any other action in the exercise of its functions as the parties may agree.
The powers of the commission are quite broad.
