In this blog post, Megan Griffiths summarises and analyses the High Court’s recent decision in Bell v Tavistock NHS Trust. This judicial review decision looks at informed consent practices for children and young people with gender dysphoria, whether they can achieve Gillick competence for consenting to puberty blocking treatment, and what such consent processes would require in practice. This decision is likely to impact on guidance specific to gender dysphoria, but the findings on the types of information required for informed consent in young people are also likely to be relevant to other areas of clinical practice.
