Britain is mired in yet another constitutional row this week after the United Kingdom government took the unprecedented step of vetoing Scottish legislation that sought to reform gender identity laws. The Gender Recognition Reform Bill was passed by the semi-autonomous Scottish Parliament in December last year, and intended to make it easier for transgender people to legally change their gender identity. Under the devolution arrangement which grants Scotland some degree of political autonomy, gender recognition falls under the exclusive competence of the Scottish Parliament to legislate on. The British government can technically choose to veto any Scottish legislation if it fails to comply with existing U.K.-wide laws, though this step has never been taken before.
