Consent may be a complete or partial defense to assault. In some jurisdictions, most notably England, it is not a defense where the degree of injury is severe, as long as there is no legally recognized good reason for the assault.(RvG ref 6. 1980): see This can have important consequences when dealing with issues such as consensual sadomasochistic sexual activity, the most notable case being the Operation Spanner case. Legally recognized good reasons for consent include surgery, activities within the rules of a game (mixed martial arts, wrestling, boxing, or contact sports), bodily adornment (R v Wilson [1996] Crim LR 573), or horseplay (R v Jones [1987] Crim LR 123). However, any activity outside the rules of the game is not legally recognized as a defense of consent. In Scottish law, consent is not a defense for assault.
