[1901] UKHL 2; [1901] AC 495

Citation: [1901] UKHL 2; [1901] AC 495
Court: House of Lords (United Kingdom)
Date: 5 August 1901
Bench: Earl of Halsbury L.C.; Lords Macnaghten, Shand, Brampton, Robertson and Lindley

Facts

Leathem operated a butcher’s business in Lisburn and employed several non-union workers.
Quinn and other officials of the Belfast Journeymen Butchers’ Association wanted Leathem to employ only union members.
Leathem was willing to allow his workers to join but would not dismiss employees who refused.
Union officials then pressured persons dealing with Leathem.
They threatened industrial action against Munce, a longstanding customer, unless he stopped purchasing meat from Leathem.
They also induced one of Leathem’s employees to leave and circulated information intended to isolate the business.
Munce ended his commercial dealings with Leathem.
Leathem suffered financial loss and sued the union officials for conspiracy, intimidation and unlawful interference.
A jury found that the defendants’ dominant object was to injure Leathem and awarded damages.
The House of Lords considered whether collective trade-union action could be actionable even where some individual acts might have been lawful if performed by one person.

Whether union officials were liable for collectively interfering with Leathem’s business.
Whether lawful acts become actionable when performed in combination with the predominant purpose of causing injury.
Whether inducing customers or workers to break commercial or employment relations required legal justification.

A person has a legally protected interest in carrying on business and maintaining contractual relations without unjustified interference.
Intentionally inducing breach of contract may be actionable.
A combination of persons acting with the predominant purpose of injuring another may constitute an unlawful conspiracy where damage results.
Collective action undertaken genuinely to protect legitimate trade interests may stand differently from action whose dominant object is personal or commercial injury.
Liability depends upon:
intention;
purpose;
means used;
absence of sufficient justification; and
actual damage.
The judgment pre-dated later legislation granting trade unions wider immunities for acts done in contemplation or furtherance of trade disputes.

The defendants were not merely persuading Leathem’s own workers to join the union.
They deliberately targeted third parties who had longstanding commercial relations with him.
Munce was threatened with industrial disruption in his own business unless he stopped purchasing from Leathem.
The jury found that the dominant object was to punish and injure Leathem for resisting the closed-shop demand.
The House of Lords treated this factual finding as decisive.
The defendants argued that:
Munce was legally free to stop purchasing;
workers were free to leave employment; and
the union was advancing collective labour interests.
The Court held that formal freedom of the immediate actor did not necessarily protect those who intentionally procured the harmful result through concerted pressure.
The pressure was directed beyond ordinary negotiation with the employer and was intended to destroy his business relationships.
No sufficient trade justification displaced the jury’s finding of malicious injury.
The combination, intimidation and inducement therefore produced actionable loss.
From a labour-law perspective, the decision demonstrates the historically narrow judicial protection given to collective action before statutory trade-dispute immunities.
It must consequently be read as a historical authority, not as a complete statement of modern trade-union immunity.

The House of Lords dismissed the union officials’ appeal.
It upheld the finding that they had unlawfully conspired to injure Leathem’s business and had intentionally interfered with his contractual and commercial relations.
Damages remained payable.
Use this case for: historically, concerted union pressure directed mainly at injuring an employer’s business could attract liability for conspiracy and interference, particularly before statutory trade-dispute immunities.
