LONDON (AFP) - A campaigner seeking gender-neutral passports won the right on Wednesday (Oct 11) to mount a challenge against the British government in the High Court.

Christie Elan-Cane, who does not identify as either male or female, believes Britain's passport application process is inappropriate.

At a hearing in London, High Court judge Andrew Gilbart granted the campaigner permission to bring a judicial review. A date for the challenge hearing has yet to be fixed.

"I am really elated but it is just one stage. There's still lots of work to do. We are not there yet," Elan-Cane said after the hearing.

The campaigner claimed the British government was discriminating against its citizens in recognising gender-neutral passports held by citizens of other countries but not offering them to UK nationals.

Canada recently joined Australia, Denmark, Germany, Malta, Nepal and Pakistan in issuing gender-neutral passports.

Elan-Cane's lawyer Kate Gallafent said her client considered that obtaining a passport would involve making a false declaration of gender identity.

The Passport Office's "refusal to provide for X passports affects not only non-gendered persons such as the claimant, but a broad section of the public", she said.

Those affected included inter-sex people, transgendered individuals and people with gender dysphoria.

"The size of the potentially affected class is substantial; it has been estimated to be as high as one per cent of the population," she said.
