Ms Peggie’s legal team said that work on the appeal is progressing and that the notice of appeal is expected to be submitted to the Employment Appeal Tribunal within the coming week.
On Monday, a tribunal ruled the Royal College of Nursing (RCN) did not discriminate against Ms Peggie because of her gender beliefs.
Ms Peggie accused the union of failing to support her during a row with her employer NHS Fife.
She previously brought a case against NHS Fife after sharing a changing room with transgender medic Dr Beth Upton at Kirkcaldy’s Victoria Hospital in December 2023.
In December 2025, a separate tribunal awarded Ms Peggie a partial victory, upholding claims of harassment against her employer but dismissing allegations of discrimination, indirect discrimination and victimisation.
Her case against the RCN was heard at an employment tribunal in Dundee in September and October this year.
Ms Peggie accused the union of failing to advise her properly when she raised the changing room issue with one of the RCN’s officers.
She alleged that the union had refused her request for legal assistance in relation to her claims against NHS Fife, and said it had failed to seek assurances from NHS Fife on its policies on single-sex spaces.
On Monday, all three of Ms Peggie’s claims against the union were dismissed.
Employment Judge Melanie Sangster said: “The Tribunal concluded that the complaints of direct discrimination, to the extent that they were framed as being because of an asserted belief of the respondent, could not succeed.”
