Australian judges have ruled that people do not have to be registered as a man or a woman on the register of births, deaths and marriages.
The New South Wales Court of Appeal overturned an earlier decision that a person’s sex could not be listed as “non-specific” under Australian law.
The court ruled that sex does not bear a binary meaning of “male” or “female”.
