House of Lords · 3-2: Lords Templeman, Jauncey and Lowry; Lords Mustill and Slynn dissenting
Facts
The appellants, a group of adult men, took part over several years in private, consensual homosexual sadomasochistic encounters involving branding, beating and the infliction of wounds; none of the injuries required medical treatment. They were charged with assault occasioning actual bodily harm (section 47) and unlawful wounding (section 20) under the Offences Against the Person Act 1861. After the trial judge ruled that consent was no defence, they pleaded guilty.
History
After the trial judge ruled that consent afforded no defence, the appellants pleaded guilty. The Court of Appeal (Criminal Division) dismissed their appeals against conviction and certified a point of law of general public importance for the House of Lords.
Issue
Whether the consent of the victim constitutes a valid defence to charges of assault occasioning actual bodily harm and unlawful wounding when the harm is inflicted during private, consensual sadomasochistic activity.
Held
Appeals dismissed. Consent is not a defence to the infliction of actual bodily harm or more serious injury in the context of sadomasochistic acts. Convictions upheld.
Ratio
- A person cannot consent to the infliction of actual bodily harm or wounding except where the act falls within a recognised exception such as properly conducted surgery, lawful sport, ritual circumcision, tattooing, or ear-piercing. Sadomasochistic activity does not fall within any such exception.
The judgments
Lord Templeman (lead)
He held that the infliction of actual bodily harm is unlawful unless justified by a recognised exception. Consent is irrelevant where the harm is more than transient or trifling. The policy of the law is to protect citizens from physical harm, and the exceptions are limited to activities that serve a useful social purpose.
Lord Jauncey (concurring)
He agreed that consent is not a defence to actual bodily harm. He emphasised that the law draws a line at injury that is more than transient or trifling, and that the recognised exceptions are exhaustive. The appellants' activities were not within any exception and were properly criminalised.
Lord Lowry (concurring)
He concurred on the basis that the public interest requires the criminal law to prohibit the intentional infliction of actual bodily harm outside the established exceptions. He declined to extend the exceptions to cover sadomasochistic practices.
Lord Mustill (dissenting)
He argued that the common law should recognise a general defence of consent for private acts between competent adults causing no permanent injury. He viewed the majority's approach as an unjustified intrusion into private morality and would have allowed the appeals.
Lord Slynn (dissenting)
He agreed with Lord Mustill that consent should be a defence where the harm is not serious and the activity is private. He considered that the court should not create new crimes by restricting the defence of consent beyond the existing authorities.
Key reasoning
- The Offences Against the Person Act 1861 creates offences based on the infliction of harm, not on the absence of consent.
- The common law has long recognised that a person cannot consent to serious harm, and the exceptions are narrowly defined by precedent.
- The majority treated the list of exceptions (surgery, sport, tattooing, etc.) as closed, grounded in public policy rather than individual autonomy.
- The dissenters would have developed the common law to recognise a broader defence of consent for private, non-exploitative conduct.
Obiter
- The majority accepted the existing categories in which consent remains a defence despite injury, including properly conducted sports, lawful surgery, tattooing and ear-piercing, and rough horseplay as recognised in R v Jones (1986), but refused to add sadomasochism to them.
Where it fits in the module
Brown is the central case on the limits of consent to non-fatal offences. Later Court of Appeal decisions test its reach: R v Wilson (1997) refused to apply it to a husband branding his wife's buttocks with her consent, likening it to tattooing, while R v Barnes (2004) confined criminal liability for sporting injuries to conduct sufficiently grave to be criminal. The case frames the module's debate between the harm principle and legal moralism, and the choice between a general rule with listed exceptions and a principle of autonomy.
Criticisms
- The closed list of exceptions lacks a principled basis and appears to reflect judicial moral preferences rather than coherent policy.
- The decision criminalises private, consensual conduct between competent adults without demonstrating harm to third parties or public order.
- The distinction between tattooing (lawful) and branding (unlawful) is arbitrary and difficult to justify on the basis of injury severity alone.
- The ruling creates an anomaly: a person may consent to the risk of serious injury in boxing or rugby, but not to controlled injury in a private sexual context.
