Operation Spanner: The Case That Made Consent No Defence

Operation Spanner is the case UK kink communities cite when they want to explain, quickly, why the law is not on their side. The shorthand does a lot of work and gets the details wrong about as often as not, which is a reason to set out what the record shows.

What the police thought they had found

In 1987 the Metropolitan Police came into possession of videotapes made by a group of gay men who had been meeting for sadomasochistic sex over a period of years. Accounts of the investigation say officers initially believed the footage might show murder. It did not. Nobody had died, nobody had been coerced, and nobody had complained. The participants were identified from the tapes they had made themselves.

The investigation ran for around three years and reached men across the country. That in itself shaped the case’s reputation: what the community saw was not a response to a complaint but a police operation that went looking, found a private network, and prosecuted it.

The charge that stuck

The Crown charged assault occasioning actual bodily harm under section 47 of the Offences Against the Person Act 1861, and unlawful wounding under section 20. The 1861 Act was not written with any of this in mind, and the question the charges raised was simple to state and hard to answer: can a person consent to being injured.

The trial judge ruled that they could not, and that consent was therefore no defence. Most of the defendants changed their pleas to guilty once that ruling was made. Sixteen men were convicted at the Central Criminal Court in December 1990, and several received custodial sentences. The Court of Appeal upheld the convictions in February 1992 but reduced some sentences, accepting that the men had not understood that what they were doing was a crime.

R v Brown

The case reached the House of Lords as R v Brown and was decided in March 1993. The certified question was narrow: whether the prosecution had to prove the absence of consent in charges of this kind. By three votes to two, the Lords answered that it did not.

The majority reasoning was not really about the law of assault. It was about where public policy should draw a line, and the judgments discussed the risk of infection, the possibility of escalation, and the corruption of young men. The two dissenting law lords took a different view: that this was private conduct between consenting adults, that criminalising it was a matter for Parliament rather than for judges, and that the majority was in substance creating an offence rather than applying one.

The result left English law with an inconsistent map. Consent operates as a defence to injury in boxing, in surgery, in tattooing and piercing, and in what the judgments called rough horseplay. It does not operate here. Three years later, in R v Wilson, the Court of Appeal quashed the conviction of a man who had branded his initials on his wife’s buttocks at her request, treating it as closer to tattooing than to Brown. The distinction has been criticised in every direction since, and the most common criticism is the plainest one: the two sets of facts are hard to tell apart on any principle the judgments articulate.

Strasbourg

Three of the men took the case to the European Court of Human Rights, arguing that their prosecution had breached Article 8 of the Convention, the right to respect for private life. In Laskey, Jaggard and Brown v United Kingdom, decided in February 1997, the court agreed that Article 8 was engaged, which was itself worth something, and then found no violation. The interference by the United Kingdom was, it held, justified as necessary for the protection of health. Ten years after the first police visit, the convictions were final.

What it left behind

A campaign, first. Organisations formed in the case’s wake, the best known taking its name from the operation, and spent years pressing for reform, briefing lawyers and journalists, and keeping the case in front of people who would otherwise have forgotten it.

A phrase, second. The Spanner case became community shorthand for a specific fear that has nothing to do with getting caught doing something unwanted: the fear that the private, negotiated and wanted can be reclassified as violence by people who were not in the room and would not recognise the difference.

And an unmoved law. R v Brown remains the leading authority in England and Wales. In 2021 Parliament put the principle into statute in section 71 of the Domestic Abuse Act, providing that consent to serious harm for sexual gratification is not a defence. That provision was aimed at defendants claiming a death or injury had occurred during consensual sex, and its effect on the Spanner question was to restate Brown rather than to reopen it.

The vocabulary the courts used through all of this was inherited, not chosen: see how sadism and masochism got their names for where it came from, and the full timeline for where this case sits in the sequence.
