Raising and Defeating a Laches Defense: A Practitioner's Guide to Delay, Prejudice, and Progressive Encroachment
By Casey Scott McKay ·
This guide runs a laches defense through eleven stages, from the answer that pleads it to the judgment that limits the remedy, and it works both chairs at once because the same facts serve both. It shows the defendant how to build the two prejudice records courts actually credit, and how to avoid the overclaim that discredits everything else in the declaration. It shows the plaintiff how to reset the clock through progressive encroachment, how to plead an encroachment date rather than a use date, and how to attack a prejudice claim by filtering it through the delay window. There is a discovery plan aimed at the plaintiff's watch service and triage files, model pleading and declaration language, a briefing structure for the circuit-specific factor tests, and a remedy section on the tailored injunction that most of these cases actually produce. One invented matter, Ferrous and Fife v. Hearthwyck Provisions, carries the whole sequence.
