UK Supreme Court rules legal sex is biological, sparking fear and discrimination fears among trans people.

A UK Supreme Court ruling in April 2025 defining legal sex as biological sex has triggered fear and uncertainty among transgender people, with advocates and individuals like Nate Rae reporting increased anxiety, safety concerns, and avoidance of public spaces. The decision, which classifies transgender men as female and transgender women as male, has led to new guidance suggesting trans people be excluded from facilities designated for their lived gender, including women’s shelters and hospital wards. While the Equality and Human Rights Commission maintains the guidance is legally accurate, critics say it enables discrimination and harms mental health. Many trans individuals are now hiding their identities, avoiding public spaces, or considering leaving the UK. The government asserts existing laws protect trans people from discrimination, but many still feel unsafe. A parliamentary review of the EHRC’s guidance is expected by year’s end.
