Non-Fatal Offences Against the Person Act 1997
Consent by minor over 16 years to surgical, medical and dental treatment.
23.—(1) The consent of a minor who has attained the age of 16 years to any surgical, medical or dental treatment which, in the absence of consent, would constitute a trespass to his or her person, shall be as effective as it would be if he or she were of full age; and where a minor has by virtue of this section given an effective consent to any treatment it shall not be necessary to obtain any consent for it from his or her parent or guardian.
(2) In this section “surgical, medical or dental treatment” includes any procedure undertaken for the purposes of diagnosis, and this section applies to any procedure (including, in particular, the administration of an anaesthetic) which is ancillary to any treatment as it applies to that treatment.
(3) Nothing in this section shall be construed as making ineffective any consent which would have been effective if this section had not been enacted.
