The reply the Deputy refers to from the HSE, sets out the HSE National Consent policy (2022) which is that it adopts a position that the consent of a young person aged 16 and 17 years (who has decision-making capacity) is sufficient (except where the Mental Health Act 2001 applies). This is in line with long established current practice and with the Medical Council, Guide to Professional Conduct and Ethics for Registered Medical Practitioners (2019) as well as with a reasonable interpretation of s. 23 of the Non-Fatal Offences Against the Person Act 1997.
The general issue of consent to certain medical treatments for 16-year-olds is dealt with in the Non-Fatal Offences Against the Person Act, 1997 which I understand is under the remit of the Department of Justice, should the Deputy wish to raise any amendments and request any further information.
