THE UK’s Equality and Human Rights Commission (EHRC) has issued legal guidance on the implications of the Supreme Court’s gender ruling, saying it is “compulsory” for workplaces to offer single-sex toilets and changing facilities.
It comes after the UK Supreme Court sided with the campaign group For Women Scotland, saying that a gender recognition certificate does not entitle a trans person to be considered their acquired sex under the 2010 Equality Act. In the act, the court ruled, sex is biological.
Earlier this week, the Scottish Government delivered its response to the ruling and called on the EHRC to issue updated guidance on the impact of the court's decision.
On Friday evening, the commission did so, publishing an “interim update on the practical implications of the UK Supreme Court judgment”.

The EHRC said: “We know that many people have questions about the judgment and what it means for them. Our updated guidance will provide further clarity. While this work is ongoing, this update is intended to highlight the main consequences of the judgment.
“Employers and other duty-bearers must follow the law and should take appropriate specialist legal advice where necessary.”
The EHRC said that the ruling means that in UK law “a trans woman is a biological man” and a “trans man is a biological woman”.
It went on: “In workplaces, it is compulsory to provide sufficient single-sex toilets, as well as sufficient single-sex changing and washing facilities where these facilities are needed.
“It is not compulsory for services that are open to the public to be provided on a single-sex basis or to have single-sex facilities such as toilets.
“These can be single-sex if it is a proportionate means of achieving a legitimate aim and they meet other conditions in the act. However, it could be indirect sex discrimination against women if the only provision is mixed-sex.”
The EHRC went on: “In workplaces and services that are open to the public: trans women (biological men) should not be permitted to use the women’s facilities and trans men (biological women) should not be permitted to use the men’s facilities, as this will mean that they are no longer single-sex facilities and must be open to all users of the opposite sex.
“In some circumstances the law also allows trans women (biological men) not to be permitted to use the men’s facilities, and trans men (biological woman) not to be permitted to use the women’s facilities.
“However where facilities are available to both men and women, trans people should not be put in a position where there are no facilities for them to use.
“Where possible, mixed-sex toilet, washing or changing facilities in addition to sufficient single-sex facilities should be provided.
“Where toilet, washing or changing facilities are in lockable rooms (not cubicles) which are intended for the use of one person at a time, they can be used by either women or men.”
It said schools “must provide separate single-sex toilets for boys and girls over the age of 8”, adding: “It is also compulsory for them to provide single-sex changing facilities for boys and girls over the age of 11.”
The EHRC further said: “Membership of an association of 25 or more people can be limited to men only or women only and can be limited to people who each have two protected characteristics. It can be, for example, for gay men only or lesbian women only.
“A women-only or lesbian-only association should not admit trans women (biological men), and a men-only or gay men-only association should not admit trans men (biological women).”
It added: “There are rules about when competitive sports can be single-sex, which we intend to address separately in due course.”
