Laches

Negligence, consisting in the omission of something which a party might do, and might reasonably he expected to do, towards the vindication or enforcement of his rights. The word is generally the syno-nym of “remissness,” “dilatoriness," “un-reasonable or unexcused delay,” the opposite of “vigilance,” and means a want of activity and diligence in making a claim or moving for the enforcement of a right (particularly in equity) which will afford ground for presuming against it, or for refusing re-lief, where that is discretionary with the court.
