11. Consent and offences against the person

This chapter examines the controversial question of whether and, if so, when a sane adult should be permitted to consent to harm to himself or to the risk of harm to himself. It considers the threshold of harm—should V be permitted to consent to any level of harm or only to minor harms; whether a person should be permitted to consent to different levels of harm in certain activities: surgery, boxing, horseplay, etc; whether the transmission or risk of transmission of diseases or infections can be consented to; and what constitutes ‘true’ consent.
