Laches

In James v Scudamore [2023] EWHC 996 (Ch), HHJ Paul Matthews reviewed the doctrine at length, confirming that laches is an equitable doctrine, under which delay can bar a claim to equitable relief. The judgment sets out Lord Selborne's classic 19th-century formulation from Lindsay Petroleum Co v Hurd, which asks whether it would be practically unjust to give a remedy because of the claimant's own conduct, and directs the court to consider the length of the delay and the nature of the acts done during the interval, which might affect either party and cause a balance of justice or injustice in taking the one course or the other. Citing Lord Neuberger in Fisher v Brooker, the judgment also notes that some sort of detrimental reliance is usually an essential ingredient of laches — it is not simply the passage of time that matters, but what happened, and to whom, during that time.

The judgment is equally clear about the doctrine's limits: laches only can bar equitable relief, so it cannot be raised as a defence to a claim for a purely legal remedy, such as (in that case) a declaration of a statutory property right. This is what marks laches out from a statutory limitation period, which operates as a fixed time bar regardless of prejudice. Laches instead requires the party relying on it to point to specific detriment or change of position caused by the delay, and its application is discretionary rather than automatic — the court weighs the equities of the particular case rather than mechanically applying a clock.
