Gillick competence

Gillick competence is the test for whether a child under 16 can consent to their own medical treatment.

Summary

  • It comes from a 1985 House of Lords case, Gillick v West Norfolk and Wisbech Area Health Authority.
  • A child is Gillick competent if they have enough understanding and intelligence to fully understand what is proposed.
  • It is judged decision by decision. A child might be able to consent to a vaccination and not to major surgery.
  • The Fraser guidelines are narrower. They come from the same case and deal with giving contraceptive advice to under 16s.
  • Young people aged 16 and 17 are presumed able to consent to their own treatment.
