The Supreme Court on Tuesday rejected the appeal of a Massachusetts student who was barred from wearing a T-shirt to school proclaiming there are only two genders. The court should have heard the case, Alito wrote, noting that “the school permitted and indeed encouraged student expression endorsing the view that there are many genders,” but censored an opposing view.

There appeared for a moment to be some kind of sea change in the approach to trans issues after the UK Supreme Court ruled in April that a woman is a woman. But this could be at risk now that officials are working to delay new legal guidance, apparently in the hope that more liberal figures can alter it in their favour first. Indeed, ‘Sex Matters’ representative Helen Joyce noted that guidance or no guidance, the Supreme Court ruling is already easy to interpret, and “those claiming that the judgment is hard to understand, or that organisations should wait for further guidance, are simply trying to sow confusion where there is none.”

Amid a national controversy involving a trans athlete competing in the girls’ category, the California Interscholastic Federation (CIF) announced a series of sweeping rule changes in the days leading up to the event to accommodate female competitors. But now multiple families of girls who have already been displaced by a trans athlete at previous meets have spoken out against the federation, expressing dissatisfaction with the changes.
