Ledoux v. Black
59 U.S. (18 How.) 473
In the case of an imperfect Spanish title to land in Louisiana, a confirmation by Congress is inoperative unless the title or survey under it will enable the court to ascertain the specific boundaries of the land.
If, before a survey in such a case, an entry is made and a patent taken out for land which conflicts with a subsequent survey of the confirmed concession, the patentee has the better title. chanroblesvirtualawlibrary
