A painful precedent? R v Brown, criminality and consent – by Rhiannon Frowde – The Mason Institute Blog (2025)

Who decides where normal ends and perverse begins? The leading case on consent to injury in criminal law,R v Brown, raises questions as to the role of morality inlaw.

In the UK, individualscannot consent to actual or grievous bodily harm, unless the activity falls within an excluded category, such as sport or medical treatment. InBrownthese exceptions werelegitimisedon the basis of ‘public interest’ and ‘good reason’. The case held that consensual sadomasochism occurring between adults in a private setting was not in the public interest, without adequately definingthesetests.

It appears that the distinction between permissible andcriminalisedharms is based onthe judiciary’s moral judgment, rather than coherent principles. This blog explores the ‘public interest’ test, considering itsbasisand how it may be satisfied. The justifications for boxing, a permitted exception, are contrasted with sadomasochism, demonstrating the distinction is based in morality not policy. The adoption of a circumstantial, rather than category-based approach is preferable.

R v Brown[1]

The appellants inBrownwere a group of homosexual men who had over the course of several years engaged in sadomasochistic activities for sexual gratification. A private video recording of the defendant was found during a police investigation, and the men were charged with actual bodily harm and unlawful wounding contrary to Sections47and20of theOffences Against the Person Act 1861respectively.

Almost three decades after its conclusion, this casecontinues to have wide-reaching implications, establishing a presumption against the legality of consensual harm, unless it falls within a predefined excluded category. This was justified on the basis of serving the ‘public interest’.

What is the ‘public interest’?

Preventing harm is a key principleof UK criminal law. The maximvolenti non fit injuriaillustrates the traditional position that where individuals consent, there is no resulting crime.[2]This respectspersonalautonomy,allowing individuals to shape their lives according to their beliefs, even wheretheseare not shared by society at large.[3] State interference in personal autonomy is only in the public interest where one’s actions harm others.[4]The notion of harm,however,is grounded in social standards.

This approach is reflected in the legal permissibility of certain harms, including body adornment, modification, contact sports, and medical treatment, yet illegality of other comparable acts such as sadomasochism.

At the time of the judgement,sadomasochism was regarded as a socially undersirable activity,regarded in the same light as homosexuality andtransvestitism, howeversocial attitudes have since shifted.There is increased importance placed upon bodily autonomy and freedom of sexual expression, reflected in the sensationalist novel,50 Shades of Grey,romanticisingsadomasochism.

Arguably, it is not in the public interest for the state to interfere with individuals’ privacy. Normally occurring privately between consenting adults, sadomasochism is beyond the remit of the law.

Even if the intentional infliction of injury for sexual gratification merits moral sanction, it does not necessarily follow that legal sanctions are required.[3] As withhomosexuality, moral intolerance does not and should not equate to legal intolerance. As such, the judiciary’s morals should not decide the outcome of a case.

Currently, public interest is determined by assessing if there is ‘good reason’ to make the conduct legal. InBrownthe Court of Appeal found it unnecessary to define this, despite their certainty of what conflict did or did not satisfy the test. An uncertain definition will inevitably allow outcomes to be influenced by the decision maker’s morals.[3]

The law of the rings – Boxing vs Sadomasochism

Boxing, body adornment, and medical treatment are among the excluded classes of activity, which implies they can be distinguished from sadomasochism if public interest is indeed the doctrine underlying their validity.

Boxinginvolves the intentional infliction of force for the purpose of sport and entertainment. InBrownit waslegitimisedon the basis of being deeply embedded in British culture. However,society’s increasing recognition of sexual autonomy, as explored earlier, undermines this justification.

Emphasis was also placed on the right of self-expression in sport. However, injuries sustained in boxing may be similar to those in sadomasochism,[3] and it seems wrong tocodemnviolence in sex yet encourage it elsewhere. The intention of the parties may also be questioned – in boxing the aim is to defeat an opponent through the infliction ofactual or grievous bodily harm, whereas in sadomasochism, harm is inflicted for the purpose of mutual sexual gratification.

The majority inBrownalso discussed the corruption of youths. Boxing is also likely to influence youths, being in the public arena, broadcast in graphic detail, and promoted as entertainment. Sadomasochism occurs in private, and is no more likely to influence youths than any other adult activity.

Therefore the reasoning applied to explain the public interest in boxing can equally be applied to sadomasochism, presenting a strong case for legality. It would thus seem that exceptions are based more upon the judiciary’s moral judgements than sound reasoning, such as Lord Templeman’s strong judgement describing sadomasochism as a cult of violence against which society was ‘bound to protect itself’.

Yes means no? The need for reform

Vague principles of ‘public interest’ and ‘good reason’ allow judges excessive discretion, confounding analready complex area of law.The law currently awards greater respect for sporting choices than autonomy in one’s sexual preferences. The application of the principles in a blanket ‘permitted category’ approach undermines autonomy further, failing to consider the individual facts of each case.[5]

Clear articulation of the principlestocategorisenovel forms of consensual violence in the future is necessary. Furthermore it would be beneficial toadopt apresumption of legality in consensual infliction of harm, as advocated by the minority inBrown, and adopted inNew Zealand.This permits a case-by-case assessment,balancing public interest against autonomy, only requiringcriminalisationin certain circumstances, such as where one party has acted maliciously, recklessly, or consent was not genuine.[3][6]
