South Wales Miners’ Federation v Glamorgan Coal Company: HL 1905

The union was accused of unlawful interference in contractual relations, and replied that their intention in calling a strike (inducing miners to break their contracts of employment) was to restrict production of coal and thereby raise its price.
Held: When considering the tort of unlawful interference in contractual relations, the motive of the alleged tortfeasor is irrelevant. Malice, in the form of ill-will, was not required for this tort. It was enough that the defendants knowingly and intentionally procured a violation of the plaintiffs’ legal rights. Lord Macnaghten said it was no defence that ‘if the masters had only known their own interest they would have welcomed the interference of the federation’.
