David Josiah Brewer,
Halstead v. Grinnan — Opinion of the Court
“ It is an equitable defense, controlled by equitable considerations, and the lapse of time must be so great, and the relations of the defendant to the rights such, that it would be inequitable to permit the plaintiff to now assert them. There must, of course, have been knowledge on the part of the plaintiff of the existence of the rights, for there can be no laches in failing to assert rights of which a party is wholly ignorant, and whose existence he had no reason to apprehend. ”
