"Australia’s highest court found that the 1995 Births, Deaths and Marriages Registration Act (New South Wales) recognized that a person’s sex might be ambiguous and “does not require that people who, having undergone a sex affirmation procedure, remain of indeterminate sex — that is, neither male nor female — must be registered, inaccurately, as one or the other. The Act itself recognises that a person may be other than male or female and therefore may be taken to permit the registration sought, as ‘nonspecific.’ ”
