UK Supreme Court says legal definition is based on sex at birth

The UK's Supreme Court on Wednesday ruled that UK law defines a "woman" as someone born biologically female, upholding an appeal by a Scottish group that challenged the legal recognition of transgender women. The ruling means a transgender person with a certificate recognising them as female should not be considered a woman under equality law. Co-Director of the TLGBTI+ Observatory at Jean Jaures Foundation, Flora Bolter, explains.
