Quinn v Leathem [1901] UKHL 2, is a case on economic tort and is an important case historically for British labour law. It concerns the tort of "conspiracy to injure". The case was a significant departure from previous practices, and was reversed by the Trade Disputes Act 1906. However, the issue of secondary action was later restricted from the Employment Act 1980, and now the Trade Union and Labour Relations (Consolidation) Act 1992. The case was heavily controversial at the time, and generated a large amount of academic discussion, notably by Wesley Newcomb Hohfeld, which continued long after it was overturned.
