While the Supreme Court in April backed the biological definition of a woman, it would appear that in Scotland the ruling hasn’t yet been taken into account. Women’s rights campaigners have taken aim at an Edinburgh Fringe venue – Underbelly Bistro Square – for allowing biological men to use women’s toilets. Dear oh dear…

The venue has been accused of breaking the law, after it added a disclaimer below the female bathroom sign – which told attendees to ‘use whichever toilet best fits your identity or expression’. While the men’s toilets featured a similar note, the cubicles themselves were reportedly still labelled ‘gents’. This is despite the Supreme Court ruling prompting new guidance from the Equality and Human Rights Commission, which says that although it is not compulsory for public services to have single-sex facilities, it could be indirect discrimination against women if the only toilets available are mixed sex.

The landmark case was brought to the Supreme Court by women’s rights campaign group For Women Scotland – after its argument (that the definition of women in the Equality Act referred to biological sex) was rejected by two Scottish courts. Susan Smith of the organisation told the Telegraph about the latest Fringe furore: ‘This is plainly unlawful. You can’t have a sign like that. You can either have a mixed sex space or a single sex space. It’s not possible to have both at the same time. It’s either one or the other.’ Helen Joyce of charity Sex Matters added: ‘Organisations that fail to get this right risk enabling sexual harassment and ultimately being sued.’ Oo er.

Will Underbelly push back? Stay tuned…
