In a landmark decision, the United Kingdom’s Supreme Court has determined that the legal definition of a woman is based on biological sex.

The unanimous ruling follows a long-standing legal challenge by activists who argued that legislation introduced in Scotland posed a risk of discrimination against women.

The court’s ruling is expected to have significant ramifications throughout British society, especially in areas such as healthcare and sports. In response, the U.K. government has reiterated its commitment to protect single-sex spaces, asserting that they are enshrined in law and will remain safeguarded.

However, the ruling has ignited concerns among transgender rights activists, who fear it could undermine protections for trans individuals. The Supreme Court, in its judgment, affirmed that existing U.K. equality legislation does offer protections for transgender individuals.

Prominent author J.K. Rowling praised the campaigners who fought for this legal clarity, describing them as “extraordinary, tenacious Scottish women." She added, "In winning, they've protected the rights of women and girls across the U.K."
