ARTICLE IV
Whereas it was stipulated by the second article in the treaty of peace of one thousand seven hundred and eighty-three, between His Britannic Majesty and the United States of America, that the boundary of the United States should comprehend all islands within twenty leagues of any part of the shores of the United States, and lying between lines to be drawn due east from the points where the aforesaid boundaries, between Nova Scotia on the one part, and East Florida on the other, shall respectively touch the Bay of Fundy and the Atlantic Ocean, excepting such islands as now are, or heretofore have been, within the limits of Nova Scotia; and whereas the several islands in the Bay of Passamaquoddy, which is part of the Bay of Fundy, and the Island of Grand Menan, in the said Bay of Fundy, are claimed by the United States as being comprehended within their aforesaid boundaries, which said islands are claimed as belonging to His Britannic Majesty, as having been, at the time of and previous to the aforesaid treaty of one thousand seven hundred and eighty-three, within the limits of the Province of Nova Scotia. In order, therefore, finally to decide upon these claims, it is agreed that they shall be referred to two Commissioners to be appointed in the following manner, viz: One Commissioner shall be appointed by His Britannic Majesty, and one by the President of the United States, by and with the advice and consent of the Senate thereof; and the said two Commissioners so appointed shall be sworn impartially to examine and decide upon the said claims according to such evidence as shall be laid before them on the part of His Britannic Majesty and of the United States respectively. The said Commissioners shall meet at St. Andrews, in the Province of New Brunswick, and shall have power to adjourn to such other place or places as they shall think fit. The said Commissioners shall, by a declaration or report under their hands and seals, decide to which of the two contracting parties the several islands aforesaid do respectively belong, in conformity with the true intent of the said treaty of peace of one thousand seven hundred and eighty-three. And if the said Commissioners shall agree in their decision, both parties shall consider such decision as final and conclusive. It is further agreed that, in the event of the two Commissioners differing upon all or any of the matters so referred to them, or in the event of both or either of the said Commissioners refusing, or declining or wilfully omitting to act as such, they shall make, jointly or separately, a report or reports, as well to the Government of His Britannic Majesty as to that of the United States, stating in detail the points on which they differ, and the grounds upon which their respective opinions have been formed, or the grounds upon which they, or either of them, have so refused, declined, or omitted to act. And His Britannic Majesty and the Government of the United States hereby agree to refer the report or reports of the said Commissioners to some friendly sovereign or State, to be then named for that purpose, and who shall be requested to decide on the differences which may be stated in the said report or reports, or upon the report of one Commissioner, together with the grounds upon which the other Commissioner shall have refused, declined, or omitted to act, as the case may be. And if the Commissioner so refusing, declining, or omitting to act, shall also wilfully omit to state the grounds upon which he has so done, in such manner that the said statement may be referred to such friendly sovereign or State, together with the report of such other Commissioner, then such sovereign or State shall decide ex parte upon the said report alone. And His Britannic Majesty and the Government of the United States engage to consider the decision of such friendly sovereign or State to be final and conclusive on all the matters so referred.
