John Marshall,
Vattier v. Hinde — Opinion of the Court
“ In 1802, Vattier purchased the title of Thomas Doyle, the elder, who had no title whatever. Whether he knew that a conveyance had been made to Thomas Doyle, the younger, or not, is immaterial. He could acquire nothing. The principle caveat emptor is completely applicable. The rules respecting a purchaser without notice, are framed for the protection of him who purchases a legal estate and pays the purchase-money, without knowledge of an outstanding equity. They do not protect a person who acquires no semblance of title; they apply fully only to the purchaser of the legal estate. ”
