A British activist lost a legal challenge at the UK's highest court Wednesday to the government's policy of not allowing gender-neutral passports.
Christie Elan-Cane brought the case to the Supreme Court, arguing that the requirement for passport applicants to indicate whether they are male or female breaches human rights laws.
Elan-Cane, who has spent years campaigning for legal and social recognition of Britons who identify as non-binary, said there should be an "X" option for applicants who identify as neither strictly female nor male.
A panel of judges unanimously dismissed the appeal, saying the gender of passport applicants is "a biographical detail which can be used to confirm their identity by checking it against the birth, adoption or gender recognition certificates provided and other official records."
"It is, therefore, the gender recognized for legal purposes and recorded in those documents which is relevant," Supreme Court President Robert Reed said.
