William Strong, De Treville v. Smalls — Opinion of the Court
“ Now, the act of Congress makes a certificate of sale by the commissioners evidence that the title acquired by the purchaser under the sale was a valid one, assailable only by proof of one or the other of three things. It is not the certificate of an assessment or of an advertisement of a sale, followed by an actual sale, to which such an effect is given, but a certificate of sale alone. We are not at liberty to interpolate in the statutes requisites for the certificate which the statute does not demand. ”
