"The Scottish Bill tears up the UK’s criteria for awarding a gender recognition certificate based on medical assessment, and allows anyone to get a GRC based on a declaration, with no medical treatments or safeguards. This means there will be many more people able to get a certificate, and organisations will never be able to feel confident excluding someone who is clearly male from female-only spaces and services. A key question for the UK Government is whether they will accept people who have been through the Scottish system but were born in England and Wales to change the sex on their birth certificate. Scotland would in effect act like a 'haven' of light regulation that would then spill out across the UK. For schools there would be huge problems. Single-sex schools are allowed by law, but now schools would face having to admit a child of the opposite sex, and would be threatened with criminal penalties if teachers and staff 'disclose' the child’s actual sex to other staff, pupils or parents. The UK Government does not have to accept this outcome. It should refer the Bill to the Supreme Court and make sure that the Scottish Parliament only legislates within its own domain, and does not ignore women’s rights and child safeguarding."
