Fraser Guidance/Gillick Competency
The Gillick ruling in 1985 established a precedent for treating minors in the UK without their parents' consent. The ruling stated that minors of any age who are able to understand what is proposed and have "sufficient discretion to be able to make a wise choice in their best interests" are competent to consent for medical treatment.
The important principles are that a young person of any age can give valid consent to treatment provided that she is considered legally competent to make that decision.
The guidelines set out by Lord Fraser in his judgement of the Gillick case are referred to as the Fraser Guidelines.
What if the young woman cannot consent?
It is your duty as a doctor to act in the young woman's best interests.
