- Appellants: Brown (Anthony), Lucas, Jaggard, Laskey and Carter • Prosecution: The Crown
Facts
The five appellants were convicted on various counts of assault occasioning actual bodily harm and unlawful wounding under the Offences Against the Person Act 18611 (OAPA), after it was revealed that the injuries had been inflicted during consensual homosexual sadomasochistic activities, many of which had been filmed and later obtained by the police; although all of the acts were committed in private with the full consent of adult participants, evidence showed that one of the appellants had introduced a participant to these practices when he was only 15 years old, and at trial the judge ruled that the victims’ consent could not provide a defence in law, leading the appellants to plead guilty and pursue an appeal, where the Court of Appeal upheld the convictions but certified a point of law of general public importance for further consideration.
Issues Raised
The central legal issue in this case concerns the interpretation of sections 20 and 47 OAPA2. Section 20 criminalises the act of wounding or inflicting grievous bodily harm, while section 47 deals with assault occasioning actual bodily harm.
- The first question is whether, in prosecutions under these provisions where the injuries arise in the course of consensual sadomasochistic encounters, the prosecution must demonstrate that the injured party did not in fact consent to the acts in question.
- The second question regards whether consent can be given lawfully Thto the intentional infliction of actual bodily harm or grievous bodily harm, where the sole purpose of the conduct is the pursuit of private sexual gratification.
Arguments of the Parties
Appellants:
- The appellants put forward the contention that consent should operate as a complete and absolute defence to charges under sections 20 and 47. Their argument is grounded in the principle of individual autonomy: every person has the right to decide what may be done with his or her own body, particularly in intimate or sexual contexts. If two adults willingly agree to engage in certain practices, even if those practices involve the infliction of injury, the state should not intervene by criminalising their conduct.
- At the very least, the appellants argued, the law of consent should only fail when the conduct in question intends to cause, or in fact does cause, grievous bodily harm. In such extreme cases, consent could be deemed invalid. However, for cases involving actual bodily harm or non-serious wounds, the defence of consent should remain open to defendants. This would allow the law to distinguish between trivial injuries willingly sustained in private sexual activity and truly serious harms that may warrant state intervention.
- The appellants further submitted that the criminal law has no place in regulating private, victimless conduct between consenting adults. They relied heavily on Articles 7 and 8 of the European Convention on Human Rights3(ECHR), which protect individuals against retrospective criminalisation and safeguard the right to respect for private life. In their view, consensual sadomasochistic activity falls squarely within the sphere of private life and autonomy protected by these provisions, meaning that state interference would be disproportionate and unjustifiable.
- Finally, the appellants contended that the use of the OAPA was inappropriate in these circumstances. They argued that Parliament had already created specific sexual-offence statutes which would apply if criminalisation of such conduct was intended. To prosecute under the general provisions of the 1861 Act amounted to an abuse of process and represented an overreach of the criminal law beyond what was contemplated by the legislature.pr
Prosecution:
- The Director of Public Prosecutions, representing the state, took the opposite stance. They relied on long-standing common law principles and statutory authorities to assert that consent is not, and never has been, a valid defence where the conduct inflicts more than what the courts describe as a “transient or trifling4” injury. In other words, once the injury crosses the threshold of seriousness—such as actual bodily harm or more serious injuries—the defence of consent is automatically excluded.
- The DPP further emphasised that sadomasochistic violence is inherently harmful and carries with it serious medical, psychological, and social risks. Such risks, they argued, exist regardless of whether the acts occur in private or with the full agreement of the parties involved. Because of this, the state has a legitimate and compelling interest in prohibiting such practices through the criminal law, in order to protect both individuals and society at large. The public interest, in their view, decisively outweighs any claim to privacy or autonomy in such cases.
- The DPP also rejected the appellants’ reliance on human rights provisions. They argued that the certified question before the court is one of domestic criminal law, not of European human rights law. While Articles 7 and 8 protect privacy and prevent retroactive offences, they do not obligate the United Kingdom to tolerate intentionally harmful conduct. In the view of the prosecution, consensual sadomasochistic violence falls outside the scope of protected private life because it involves intentional physical harm, and therefore it can legitimately be subject to prohibition under national law.
Judgment
In delivering its judgment, the House of Lords held by a majority that the defence of consent cannot be relied upon in prosecutions under sections 47 and 20 of the OAPA where the injuries result from sadomasochistic activities. The court emphasised that society has a legitimate interest in protecting individuals from physical harm, even in cases where the injured party voluntarily consented to the acts.
Lord Templeman, writing in strong terms, declared that society is both entitled and bound to defend itself against what he described as a “cult of violence5,” stressing that deriving pleasure from inflicting pain is an “evil thing6” and that cruelty of this nature cannot be tolerated under the law.
Similarly, Lord Lowry rejected the notion that the appellants’ activities could be shielded by consent7, highlighting that sadomasochistic violence, particularly within the context of homosexual relationships, could not be regarded as contributing to family life or the welfare of society. In his view, exempting such conduct from criminal liability would effectively legitimise practices rooted in cruelty, encourage harmful behaviour, and undermine the very purpose of the statutory provisions designed to prevent and punish the deliberate infliction of bodily harm.
Legal Reasoning / Ratio Decidendi
The ratio decidendi of the case rests on the principle that consent cannot serve as a valid defence to charges under sections 47 and 20 of the OAPA when the conduct involves the deliberate infliction of actual or grievous bodily harm, even where such harm arises in the context of private, consensual sadomasochistic activity.
The reasoning of the majority was that the statutory provisions were enacted specifically to criminalise and punish the very type of injury caused in this case, and allowing consent to operate as a defence would undermine the protective function of the law. This approach was consistent with earlier authorities such as R v Donovan [1934]8, where it was held that consent is not a defence if the injury caused is more than “transient or trifling9,” and Attorney-General’s Reference (No. 6 of 1980) [1981]10, which confirmed that intentional bodily harm cannot be legitimised through mutual agreement.
Against this backdrop of authority, the House of Lords in Brown reaffirmed that the criminal law does not usually interfere with matters of purely private morality; however, once physical injury surpasses the level of the trivial, it becomes a matter of public concern and falls squarely within the scope of criminal liability.
The binding rule established by the case is that in English criminal law, consent does not extend to the intentional infliction of bodily harm at the level prohibited by sections 20 and 47, thereby limiting the defence of consent to cases involving injuries that are trivial, fleeting, or otherwise outside the scope of serious violence.
Dissent
Lord Mustill’s dissent offered a fundamentally different perspective, shifting the focus from morality to legality. He argued that the central issue was not whether the appellants’ behaviour was morally acceptable, but whether it was correctly prosecuted under the OAPA. For Mustill, the law’s role was not to enforce society’s moral disapproval of unconventional sexual practices but to determine whether the statutory framework properly captured such conduct. He was careful to emphasise that his reasoning did not amount to an endorsement of sadomasochism or to a libertarian rejection of all moral standards; instead, he framed the matter as one of private morality, to be governed by individual conscience or the ethical standards of religious and social communities, rather than by the criminal courts. In his view, the state should interfere with individual autonomy only when it is necessary to protect the wider interests of society, and the appellants’ consensual activities did not cross that threshold.
Conclusion
In conclusion, R v Brown [1993] remains a landmark decision that illustrates the tension between individual autonomy and the protective function of the criminal law. The majority of the House of Lords reinforced the principle that consent cannot legitimise the deliberate infliction of actual or grievous bodily harm, grounding their reasoning in long-standing precedents, and affirming that society has an interest in preventing cruelty even in private settings. The binding rule to emerge is clear: under English law, the defence of consent is strictly limited, and it cannot be invoked to excuse intentional infliction of serious injury. Yet the vigorous dissent ensures that Brown continues to provoke debate, not only in criminal law but across fields such as human rights and contract law, where the boundaries of personal freedom and state intervention are constantly tested.
