"The High Court... recognises that a person may be neither male nor female, and so permits the registration² of a person's sex as 'non-specific'," it said in a unanimous（全体一致的） judgement, dismissing a New South Wales state appeal to recognise only men or women.

 

The case centred on a person called Norrie -- who does not identify as either male or female -- who fought a legal battle for a new gender-neutral category.

 

Norrie, who uses only a single name, was born male and underwent gender reassignment surgery in 1989 to become a woman.

 

But the surgery failed to resolve Scottish-born Norrie's ambiguity³ about their sexual identity, prompting a push for the recognition of a new, non-traditional gender.

 

The campaigner made global headlines in February 2010 when an application to the NSW Department of Births, Deaths and Marriages accepted that "sex non-specific" could be accepted for Norrie's records.

 

But soon afterwards the office revoked⁴ its decision, saying the certificate was invalid⁵ and had been issued in error. At the time, Norrie said the decision felt like being "socially assassinated⁶".

 

That sparked a series of appeals which resulted in the NSW Court of Appeal recognising Norrie as gender neutral last year, a decision which the High Court backed on Wednesday.

 

Norrie's lawyers argued in court that the activist⁷ was "being forced to live a lie" every time their client filled out a document that listed only two options for gender.

 

"Norrie's sex remained ambiguous so that it would be to record misinformation in the register to classify her as male or female," the judgment⁸ said.

 

Norrie told AFP last year that most people did not have a problem accepting a non-specific sex category.

 

"People seem to be able to accommodate the truth," the Sydney resident said.

 

"I'm not the first person like this in society, I'm the one that happened to put my hand up for this particular case -- I stand on the shoulders of giants."

 

The Intersex International Australia organisation⁹ welcomed the High Court ruling.

 

"We hope that the media will respect the difference between intersex and transgender identities, and identify Norrie's gender as 'non-specific'," it said.
