She Was Told She Wasn’t a Woman. Australia’s Highest Court Just Ended the Fight

Australia’s High Court has refused the final attempt to appeal the landmark Tickle v Giggle transgender discrimination case, leaving one of the country’s most important gender identity rulings standing.

The long-running legal battle between transgender woman Roxanne Tickle and women-only social platform Giggle for Girls has reached what appears to be its final Australian courtroom.

On 10 September, the High Court of Australia refused Giggle for Girls and founder Sall Grover special leave to appeal.

In wonderfully unambiguous legal language, the country’s highest court said there was no reason to doubt the Full Federal Court’s interpretation of the relevant provisions of Australia’s Sex Discrimination Act — and that an appeal based on challenging that interpretation had insufficient prospects of success.

Special leave was therefore refused.

With costs.

And after years of litigation, that is a rather significant full stop.

How did Tickle v Giggle begin?

Roxanne Tickle joined Giggle for Girls, a social networking app marketed as a women-only space, in 2021.

The app initially accepted her after facial-recognition software assessed her selfie. Her access was later restricted following a manual review.

Tickle subsequently brought a discrimination complaint.

In 2024, the Federal Court found that she had experienced unlawful gender identity discrimination. The original decision awarded her A$10,000 compensation.

Giggle and Grover appealed.

Tickle also cross-appealed, arguing that what happened amounted to direct, rather than indirect, discrimination and seeking increased compensation.

Then came another significant ruling.

In May this year, the Full Federal Court unanimously upheld the essential outcome of the case and found two acts of direct gender identity discrimination. Tickle’s compensation was increased to A$20,000, plus limited legal costs.

Giggle then attempted to take the matter to Australia’s highest court.

That attempt has now failed.

What exactly did the High Court decide?

This distinction matters.

The High Court did not conduct another full trial and issue a sweeping new judgment defining transgender identity.

Instead, Giggle and Grover needed the High Court’s permission — known as special leave — to appeal the Full Federal Court decision.

They didn’t get it.

Six High Court justices said there was no reason to doubt the lower appeal court’s interpretation of sections 7D(1) and 7D(2) of the Sex Discrimination Act and concluded that an appeal relying on establishing an error in that interpretation did not have sufficient prospects of success.

The application was rejected, with costs.

That leaves the Full Federal Court judgment intact.

Why the ruling matters for trans Australians

The case became much bigger than one person and one app.

Australia added gender identity protections to the federal Sex Discrimination Act in 2013. Tickle v Giggle became the first Federal Court case to test those protections in this way.

The Full Federal Court’s judgment provided important clarification: protections against discrimination based on gender identity cannot simply be sidestepped by arguing that excluding trans women benefits another group.

The Australian Human Rights Commission described the May judgment as providing important clarity on gender identity discrimination protections.

That does not mean every question involving sex, gender, women’s spaces or exemptions under Australian law has suddenly been answered.

Courts decide the particular legal questions placed before them.

But this particular fight has produced an unmistakable result.

Roxanne Tickle was protected by Australia’s anti-discrimination law.

She was unlawfully discriminated against.

And the country’s highest court has now declined to reopen the battle.

Some arguments simply reach the end of the road

There will undoubtedly continue to be political disagreement around the case.

Grover and supporters of her position argue that female-only spaces should be permitted to exclude transgender women on the basis of sex. Others view the judgment as an essential confirmation that transgender Australians cannot be excluded from services simply because somebody refuses to recognise their gender identity.

That broader debate will continue.

But courts are not comment sections.

After a trial, an appeal, a cross-appeal and now an application to Australia’s highest court, the legal outcome is what it is.

For Roxanne Tickle, who first made her discrimination complaint in 2021, that means a case which has consumed years of her life may finally be over.

And for transgender Australians, a landmark discrimination judgment remains standing.

Sometimes justice arrives with a dramatic declaration.

Sometimes it arrives in three short paragraphs from the High Court.

Either way, this one matters.
