The UK Supreme Court ruled that a woman is someone born biologically female, excluding transgender people from the legal definition. The ruling brings clarity to a contentious issue that has polarized politics in other countries. Trans rights advocates and LGBTQ groups condemned the judgment, while women's groups celebrated the decision as a major victory in their effort to protect spaces designated for women. The British government welcomed the ruling, stating that single-sex spaces are protected in law and will always be protected by the government.
