The Queensland Government has used alternative legal powers to once again ban public clinics from initiating puberty blockers and cross-sex hormones for transgender teens, following its Supreme Court loss on Tuesday.

The original ban began in January amid a government-ordered review of treatment protocols, but a mother whose transgender teenager was unable to access hormone therapy successfully challenged it in court.

Justice Peter Callaghan ruled that Queensland Health director-general Dr David Rosengren had failed to consult with health services before issuing a directive that affected them — as required under section 48 of the Hospital and Health Boards Act 2011.

He overturned the ban and ordered Queensland Health to cover the woman’s legal costs.
