Hill v CA Parsons Ltd [1972] Ch. 305
Contract law – Breach of contract – Injunctions – Employment
Facts
The defendant, an engineering company, agreed with a trade union that after 12 months, their technical staff would become members of the trade union. The plaintiff was an employee, who had worked for the engineering company for over 30 years and had recently joined a professional engineer union. The defendants gave him one month’s notice to join their trade union, which he did not do. The plaintiff was 63 years of age. Shortly afterward, the company terminated the employment of the plaintiff and thirty-seven others, with one month’s notice. The plaintiff claimed for an injunction to prevent the defendants from terminating his employment. The trial judge held that he did not have the power to grant this to the plaintiff. The plaintiff subsequently appealed the decision.
Issue
The key issue for the court was to understand whether the plaintiff could impose an injunction upon the defendant’s termination of employment. This was an important decision for the court as if the plaintiff could not use this, it is likely that his employment would be terminated early and at 63 years of age, this might have given him difficulty. He would also only have damages available to him if this action failed.
Decision/Outcome
The court allowed the plaintiff’s appeal. The plaintiff was owed at least six months’ notice with regards to the termination of his employment. Further to this, damages were not considered to be an adequate remedy and therefore the plaintiff was entitled to be able to rely on an injunction to prevent the defendant’s actions.

This article accurately summarises the facts, issue, and outcome of Hill v CA Parsons Ltd [1972] Ch 305, and the legal principles described remain good law. The case is still regularly cited as authority for the proposition that, in exceptional circumstances, a court may grant an injunction to restrain a wrongful dismissal rather than confining a claimant to damages — particularly where damages would be inadequate and mutual trust and confidence between employer and employee remains intact.
Readers should note one important contextual development: the Industrial Relations Act 1971, which formed part of the backdrop to the decision (the dismissal was connected to pressure to join a closed-shop union arrangement under that Act), was subsequently repealed by the Trade Union and Labour Relations Act 1974. Closed-shop arrangements and compulsory union membership of the kind at issue in this case are now unlawful under the Trade Union and Labour Relations (Consolidation) Act 1992. The case therefore has limited direct relevance to modern industrial relations law, but retains significant doctrinal importance in the law of contract and equitable remedies, particularly regarding the availability of injunctions in employment disputes. The broader principle — that an injunction may exceptionally be granted to prevent termination of employment — has been developed and refined in later cases such as Powell v Brent London Borough Council [1988] ICR 176 and Irani v Southampton and South West Hampshire Health Authority [1985] ICR 590, which students should read alongside this case.
