"Where two adult persons consent to participate in sexual activity in private not intended to cause any physical injury but which does in fact cause or risk actual bodily harm, the potential for such harm being foreseen by both parties, does consent to such activity constitute a defence to an allegation of assault occasioning actual bodily harm contrary tosection 47 of the Offences Against the Person Act 1861 ."
"I just pulled it off straight away, I didn't realise how far the bag had gone."
"It was accepted by all the appellants that a line had to be drawn somewhere between those injuries to which a person could consent to an infliction upon himself and those which were so serious that consent was immaterial. They all agreed that assaults occasioning actual bodily harm should be below the line, but there was disagreement as to whether all offences against section 20 of the Act of 1861 should be above the line or only those resulting in grievous bodily harm."
"I prefer the reasoning of Cave J in Coney and of the Court of Appeal in the later three English cases which I consider to have been correctly decided. In my view, the line properly falls to be drawn between assault at common law and the offence of assault occasioning actual bodily harm created bysection 47 of the Offence Against the Person Act 1961 , with the result that consent of the victim is no answer to anyone charged with the latter offence or with a contravention of section 20 unless the circumstances fall within one of the well-known exceptions such as organised sporting contest and games, parental chatisement or reasonable surgery."
"The dangers involved in administering violence must have been appreciated by the appellant because, so it was said by their counsel, each victim was given a code word which he could pronounce when excessive harm or pain was caused. The efficiency of this precaution, when taken, depends on the circumstances and on the personalities involved. No one can feel the pain of another. The charges against the appellants were based on genital torture and violence to the buttocks, anus, penis, testicles and nipples. The victims were degraded and humiliated, sometimes beaten sometimes wounded with instruments and sometimes branded... There were obvious dangers of serious personal injury and blood infection."
"It is fortunate that there were no permanent injuries to a victim though no one knows the extent of harm inflicted in other cases."
"I am not prepared to invent a defence of consent for sado-masochistic encounters which breed and glorify cruelty and result in offences under section 47 and 20 of the Act of 1861."
"The answer to this question, in our judgment, is that it is not in the public interest that people should try to cause or should cause each other actual bodily harm for no good reason. Minor struggles are another matter. So, in our judgment, it is immaterial whether the act occurs in private or public; it is an assault if actual bodily harm is intended and/or caused. This mean that most fights will be unlawful regardless of consent.
"We are abundantly satisfied that there is no factual comparison to be made between the instant case and the facts of either Donovan or Brown: Mrs Wilson not only consented to that which the appellant did, she instigated it. There was no aggressive intent on the part of the appellant. On the contrary, far from wishing to cause injury to his wife, the appellant's desire was to assist her in what she regard as the acquisition of a desirable personal adornment, perhaps in this day and age no less understandable that the piercing of nostrils or even tongues for the purposes of inserting decorative jewellery.
"For our part, we cannot detect any logical difference between what the appellant did and what he might have done in the way of tattooing. The latter activity apparently requires no state authorisation, and the appellant was as free to engage in it as anyone else.
"In this case, the degree of actual and potential harm was such and also the degree of unpredictability as to injury was such as to make it a proper cause from the criminal law to intervene. This was not tattooing, it was not something which absented pain or dangerousness and the agreed medical evidence is in each case, certainly on the first occasion, there was a very considerable degree of danger to life; on the second, there was a degree of injury to the body."
"It is not clear to me that the activities of the appellants were exercises of rights in respect of private and family life. But assuming that the appellants are claiming to exercise those rights I do not consider that Article 8 invalidates a law which forbids violence which is intentionally harmful to body and mind.
"The attempts to rely on this article is another example of the appellants' reversal of the onus of proof of legality, which disregards the effect of sections 20 and 47. I would only say, in the first place, that article 8 is not part of our law. Secondly, there has been no legislation which, being post-Convention and ambiguous, falls to be construed so as to conform with the Convention rather than to contradict it. And thirdly, if one is looking at article 8.2, no public authority can be said to have interfered with a right (to indulge in sado-masochism) by enforcing the provisions of the 1861 Act. If, as appears to be the fact, sado-masochistic acts inevitably involve the occasioning of at least actual bodily harm, there cannot be a right under our law to indulge in them."
