Legal Case Summary
Home Office v Dorset Yacht Co Ltd [1970] AC 1004;
[1970] 2 WLR 1140; [1970] 2 All ER 294; [1970] 1 Lloyd’s Rep. 453; (1970) 114 SJ 375
NEGLIGENCE, DUTY OF CARE, BOSTRAL OFFICERS, DUTY OF CARE TO WHOM, PUBLIC POLICY, IMMUNITY FROM ACTION
Facts
Seven boys detained in a borstal – a type of youth detention centre, were working on an island under the supervision of three officers. The borstal boys escaped from the island at night with the plaintiffs’ yacht and damaged it. The plaintiffs brought an action for damages against the Home Office which was in control of the bostrals on grounds that the officers on the island were negligent as they failed to exercise control and supervision over the boys. The Queen’s Bench held that the Home Office owed duty of care to the plaintiffs, which was capable of giving rise to liability in damages. The Court of Appeal dismissed the appeal by the Home Office.
Issue
(1) Does the Home Office owe duty of care to private persons with respect to persons undergoing sentences of bostral training or the manner in which such persons were controlled while undergoing their sentences?
(2) Does public policy require that the supervisors of persons undergoing sentences of bostral training are immune from action and liability for the damages caused by such persons?
Decision/Outcome
The appeal by the Home Office was dismissed.
(1) The borstal officers owe a duty to take such care as was reasonable in all the circumstances with the view of preventing the persons under their control from causing damage if there is a manifest risk if this duty is neglected.
(2) Public policy does not require that there should be immunity from action for borstal officers.

This case summary accurately reflects the decision in Home Office v Dorset Yacht Co Ltd [1970] AC 1004. The case remains good law and is still frequently cited as a foundational authority on the duty of care in negligence, particularly in relation to liability for the acts of third parties and the limits of public policy immunity.
Readers should note, however, that the broader legal framework for establishing a duty of care has developed considerably since 1970. The neighbour principle from Donoghue v Stevenson [1932], which the House of Lords drew upon here, was subsequently refined by the three-stage test in Caparo Industries plc v Dickman [1990] 2 AC 605 (foreseeability, proximity, and whether it is fair, just and reasonable to impose a duty). More recently, the Supreme Court in Robinson v Chief Constable of West Yorkshire Police [2018] UKSC 4 reaffirmed that duty of care should be determined by reference to established categories and precedent rather than a general test applied afresh in every case. Dorset Yacht itself was cited with approval in Robinson. Students should read this case in conjunction with that wider modern framework.
The borstal system referred to in the case no longer exists; it was abolished by the Criminal Justice Act 1982. This does not affect the legal principles established by the decision.
