John McLean, United States v. Fremont — Opinion of the Court
“ The district court, having entered the decree as directed, had no jurisdiction to take any further step in the cause. It follows that the executive department must determine for itself whether any law exists authorizing that branch of the government to ascertain and survey the land, and issue a patent for it, by which the title of the United States will be devested, and transferred to the grantee. ”
