An activist named Christine Elan-Cane has been fighting for a non-gender specific passport for 25 years, and an appeal has been set in motion after a high court turned down the request. Lord Justice Bean said there were some reasons for the appeal to be heard.

Elan-Cane, who uses the pronoun per, has been fighting the government for a gender-neutral passport for over a quarter century, and now she’ll be returning to court. The goal is to have a passport with an “X” gender—Australia, Malta, Pakistan are just a few that already do this.

The case is expected to go to court again, and Elan-Cane is expected to argue that the HM Passport Office’s current policy doesn’t.

“Legitimate identity is a fundamental human right but non-gendered people are often treated as though we have no rights,” said Elan-Cane in a statement. “The UK’s passport application process requires applicants to declare whether they are male or female. It is inappropriate and wrong that someone who defines as neither should be forced to make that declaration.”
