(a) Where a question or matter of difference arising between the two Governments involving the rights, obligations, or interests of either in relation to the other or to the inhabitants of the other along the common frontier between the United States of America and Canada is to be referred to the Commission under Article IX of the Treaty, the method of brining such question or matter to the attention of the Commission and invoking its action ordinarily will be as set forth in this section.

(b) Where both Governments have agreed to refer such a question or matter to the Commission, each Government will present to the Commission, at the permanent office in its country, a reference in similar or identical terms setting forth as fully as may be necessary for the information of the Commission the question or matter which it is to examine into the report upon and any restrictions or exceptions which may be imposed upon the Commission with respect thereto.

(c) Where one of the Governments, on its own initiative, has decided to refer such a question or matter to the Commission, it will present a reference to the Commission at the permanent office in its country. All such references should conform, as to their contents, to the requirements of paragraph (b) of this section.

(d) Such drawings, plans of survey and maps as may be necessary to illustrate clearly the question or matter referred should accompany the reference when it is presented to the Commission.
