landmark court case threatened to take this progress away.The High Court has ruled that it would be ‘highly unlikely that a child aged 13 or under would be competent to give consent to the administration of puberty blockers’ and ‘very doubtful’ that a 14 or 15-year-old would be, so it would be ‘appropriate that the court should determine whether it is in the child’s best interests’ to take the medication where necessary.This takes the immediate decision about which children are given puberty blockers out of the hands of medical professionals – namely those at the Gender Identity Development Service (GIDS) run by the Tavistock and Portman NHS Trust, against which the legal action was brought.
