David Josiah Brewer,
United States v. California O. Land Company…
“ If he can defend himself by any of them at law, his adversary will have no help in equity to set these incumbrances aside; for equity will not disarm such a purchaser, but will act upon the wise policy of the common law, to protect and quiet lawful possessions, and strengthen such titles.' And the reason of this is given in Boon v. Chiles, 10 Pet. 177, 210, as follows: 'This leads to the reason for protecting an innocent purchaser, holding the legal title, against one who has the prior equity. A court of equity can act only on the conscience of a party. ”
