John Catron,
United States v. Boisdoré, 52 U.S. 63…
“ We have no authority to exercise political jurisdiction and to grant, as the governors of Spain had, and as Congress has. If we were to locate by survey the land claimed at random, in some part of the district of country known as Achoucoupoulous, exercising our discretion as respects the proper place, and to decree on our own survey, and thus divest the United States of title, then we should do what Congress has often done when surveys were ordered of claims founded on settlement, and what a Spanish governor usually did on the return of a survey; we should exercise the granting power ”
