by John Marshall, Polk's Lessee v. Wendal — Opinion of the Court
“ That every prerequisite has been performed, is an inference properly deducible, and which every man has a right to draw from the existence of the grant itself. It would, therefore, be extremely unreasonable to avoid a grant in any Court for irregularities in the conduct of those who are appointed by the government to supervise the progressive course of a title from its commencement to its consummation in a patent. ”
