4 MEXICAN WATER TREATY based on the contribution of water by each State to the river, and had substituted a doctrine of equitable apportionment. It was said that a principle which is right and proper for the seven American States ought to apply to the Mexican State of Sonora and Territory of Lower California. The argument is implied, if not expressed, that the treaty is founded upon the Santa Fe compact. Ing. Orive Alba (S. Doc. 98; p. 16) says that Mexico's 1,500,000 acre-feet is included in the difference between the 16,000,000 acre-feet allocated by the compact and the 17,850,000 acre-feet which he says comprised the virgin flow of the stream. This inference that the Mexican allocation, although guaranteed, is a part of the surplus or excess of the flow over and above the compact allocations may have considerable importance. 10. COMMITTEE REPORTS On September 27, 1945, the two committees submitted a formal report to the Mexican Senate, reciting and discussing the arguments presented in the round-table proceedings, and recommending ratification of the treaty. On the same day this report was approved the transcript of the round-table proceedings was ordered printed in the Diario de los Debates (the Mexican equivalent of the Congressional Record), and a draft of decree promulgating the treaty was approved by the Senate. (The Diario, however, has not been published since 1942.) The Mexican President signed the instrument of ratification October 16 and exchange of ratifications was ordered. (Note below the interesting omissions in the Mexican resolution of ratification.) 11. FORM OF THE MEXICAN RATIFICATION The resolution of the Mexican Senate on September 27, 1945, which approved the treaty, specifically accepted the American reservations, except that, as to the American reservations (a), (b), and (c), the Mexican resolution of ratification says: The Mexican Senate refrains from considering, because it is not competent to pass judgment upon them, the provisions which relate exclusively to the internal application of the treaty within the United States of America and by its own authorities, and which are included in the understandings set forth "It is understood" and under the letters (b) and (c). (See Treaty Series 994, p. 56.) The rather interesting restriction so placed on reservation (a) results in omitting any agreement by Mexico that the works to be built by the United States are only the eight projects named in reservation (a). The other two reservations singled out, (b) subject American officers to American statutory controls and processes, and alter or control the distribution of water to users within the territorial limits of the United States. In short, Mexico says she doesn't have to agree to those reservations because they are none of her business; but whether they are her business or not, the fact remains that she has not agreed to them and is not bound by them. The American resolution of ratification insisted that- these understandings will be mentioned in the ratification of this treaty as conveying the true meaning of the treaty, and will in effect form a part of the treaty.Epson Perfection 4870 Photo, 400 dpi, 8 bit, 1,616,206 byte
