Such acts are illegal, even between consenting adults, and these laws are enforced (R v Brown being the leading case). R v Brown dismissed the defence of consent, meaning that the men charged of sexual offences could not defend their actions. It has been pointed out that people can consent to activities such as boxing and body piercing, which also result in pain, but apparently cannot consent to BDSM. This leads to the situation that, while Great Britain and especially London are world centers of the closely related fetish scene, there are only very private events for the BDSM scene which are in no way comparable to the German "Play party" scene. Operation Spanner was the name of an operation carried out by police in the United Kingdom city of Manchester in 1987, as a result of which a group of homosexual men were convicted of assault occasioning actual bodily harm for their involvement in consensual sadomasochism over a ten-year period. The resulting House of Lords case ("R v Brown", colloquially known as "the Spanner case") ruled that consent was not a valid legal defence for wounding and actual bodily harm in the UK, except as a foreseeable incident of a lawful activity in which the person injured was participating, e.g. surgery. Following Operation Spanner the European Court of Human Rights ruled in January 1999 in Laskey, Jaggard and Brown v. United Kingdom that no violation of Article 8 occurred because the amount of physical or psychological harm that the law allows between any two people, even consenting adults, is to be determined by the jurisdiction the individuals live in, as it is the State's responsibility to balance the concerns of public health and well-being with the amount of control a State should be allowed to exercise over its citizens. In the Criminal Justice and Immigration Bill 2007, the British Government cited the Spanner case as justification for criminalizing images of consensual acts, as part of its proposed criminalization of possession of ""extreme pornography"". Following the Audiovisual Media Services Regulations 2014 the video distribution of some BDSM practices has become illegal. The United States Federal law does not list a specific criminal determination for consensual BDSM acts. Some states specifically address the idea of "consent to BDSM acts" within their assault laws, such as the state of New Jersey, which defines "simple assault" to be "a disorderly persons offense unless committed in a fight or scuffle "entered into by mutual consent", in which case it is a petty disorderly persons offense". The Defendant, Identified as Samuels, was convicted in 1967 on the counts of conspiracy to produce and distribute obscene matter, two accounts of assault by means of force, and a final count of sodomy.
