Summary of the judgement (GROK generated)
Leonardo (the employer) won completely – all of Maria Kelly’s claims were dismissed.
The judge accepted that “sex” in the Equality Act and the Workplace Regulations now means biological sex only (thanks to For Women Scotland 2025).
BUT the judge said the company’s policy of letting people use toilets according to their gender identity is still lawful because:
there were proper cubicles + single-occupancy options,
no actual incidents or complaints from anyone else,
the claimant’s fear was treated as “ideological” rather than a real detriment to her personally.
In short: biological sex is the law, but employers can still let trans-identified staff use opposite-sex toilets if they think it’s “proportionate” and provide some alternatives.
Massive blow for workplace single-sex spaces – basically says self-ID is still okay in private companies as long as they’ve got a cubicle and say they’re being inclusive.
Expect an appeal to the EAT, but for now this is being treated as the current position in England & Wales (Scotland may differ).
