Facts and Trial
R v Wilson is a significant Court of Appeal decision concerning the limits of consent as a defence to charges of assault occasioning actual bodily harm (ABH) under section 47 of the Offences Against the Person Act 1861.
At his wife’s instigation and request, the appellant branded his initials (“A” and “W”) onto her buttocks using a heated knife. He claimed it was done “for love” as a form of personal adornment because he did not know how to perform a traditional tattoo. The wife did not complain; the police discovered the marks during a medical examination for unrelated matters.
At trial, the judge felt bound by the House of Lords’ decision in R v Brown to rule that the wife’s consent was immaterial, directing the jury to convict.
Judgment
The Court of Appeal quashed the conviction, distinguishing it from prior authorities based on the following reasons:
- Lack of Aggressive Intent: Unlike cases involving sexual gratification through violence, there was no “aggressive intent” on the part of the husband.
- Analogy to Tattooing: The court found no logical difference between branding and tattooing, which is a recognised exception where an adult’s consent is a valid defence to a section 47 charge.
- Privacy of the Matrimonial Home: The court held that consensual activity between a husband and wife in the privacy of their home is not normally a proper matter for criminal investigation or prosecution.
Wider Context and Legal Authority
Wilson represents a crucial counterpoint to the restrictive approach toward consent established in R v Brown. While Brown held that consent is generally not a defence to harm at the level of ABH or above, Wilson demonstrates that the courts will occasionally recognise new or analogous exceptions based on public policy and “public interest”.
The case suggests that the “exceptional categories” where consent is valid (such as surgery, sport, or body adornment) are not a closed list but should develop on a case-by-case basis. However, its authority has been carefully circumscribed:
- Distinction from Sadomasochism: The court explicitly distinguished Wilson from sadomasochistic activities involving “torture” or “blood infection”.
- Limitation in Subsequent Case Law: In R v Emmett, the court refused to apply Wilson to a situation involving more significant harm (igniting lighter fuel on breasts and using ligatures), despite the parties being in a consensual relationship.
- Social Benefit vs. Unreasonableness: More recent analysis in cases like BM (“Dr Evil”) suggests that the Wilson exception might be underpinned by the fact that it would be “unreasonable” for the common law to criminalise such private acts, even if they lack a “discernible social benefit”.
