Sall Grover vs the Gender Lobby: The Women’s App That Sparked a Legal War (#40)
The Tickle v Giggle case played out in Australian courts, but its implications reach directly into British law. Sall Grover built a women-only app, verified users by sex using facial recognition, and was sued under anti-discrimination legislation by a male-born user. With the UK Supreme Court's 2025 ruling confirming that 'woman' means biological female under the Equality Act, every operator of a single-sex service in Britain should understand what Sall faced — and what it cost her to stand her ground.
Sall Grover spent years working as a screenwriter in Hollywood, where she experienced the kind of sustained sexual harassment that rarely makes headlines but quietly shapes careers. When she returned to Australia, she channelled that experience into building something practical: Giggle, a women-only app designed to help women find flatmates, freelance clients and community, including a space for lesbian dating. To keep the platform genuinely female, she used facial recognition at the point of entry. Apple and Google approved every version without objection. In February 2020, a male-born person who had downloaded the app — later identified as Roxy Tickle — was removed after the facial recognition flagged that the account did not belong to a woman. That decision triggered a five-year legal battle under Australian anti-discrimination law. The case, Tickle v Giggle, became one of the most closely watched sex-versus-gender disputes in the common-law world. Sall faced claims that she had discriminated on the basis of gender identity; she argued she had simply upheld the single-sex purpose of her own platform. The episode is unflinching about the personal cost. Sall describes the anxiety, the financial strain, the harassment she received, and the surreal details of the courtroom itself — including a moment involving a candle and a giggle that illustrated just how far removed proceedings had become from ordinary reality. What emerges is a portrait of what it looks like when an individual, without the backing of a large organisation, refuses to concede a principle she believes is legally and morally sound. For British listeners, the resonance is immediate. The UK Supreme Court ruled in April 2025 that the word 'woman' in the Equality Act 2010 refers to biological sex, not certificated gender. That ruling was welcomed by many who had argued that single-sex services, spaces and associations had become legally precarious under a decade of expansive administrative guidance. But the ruling does not mean the fight is over. It clarifies what the law says; it does not automatically shield every woman-centred organisation from challenge, and it does nothing to deter the kind of targeted pressure campaigns that Sall describes experiencing from the moment her case became public. The Giggle case also raises pointed questions about platforms and technology. Sall's app was approved by the two largest mobile gatekeepers in the world, only for the product's core verification feature to become the subject of litigation. British businesses and charities running women-only services — refuges, sports groups, healthcare providers, social apps — will recognise the bind: design a genuinely single-sex service and risk a legal complaint; dilute the definition and lose the point of the service entirely. Stella, Mia and Bret draw out the wider ideological context, including how Sall encountered the gender-critical community, what the term 'TERF' meant to her when she first heard it, and why she has chosen not to settle or go quiet. Her reasons for continuing — laid out in the episode's final stretch — speak to something that goes beyond one case or one app. They speak to whether individuals can still define the services they build around the reality of biological sex, and what happens to those who try.
