A German federal court has ruled that a person with a genetic abnormality who identifies as neither woman nor man can't be entered in the country's birth register under a label such as "inter" or "diverse."

The plaintiff was identified by advocacy group Dritte Option only as Vanja — born in 1989 and registered as a girl.

The Federal Court of Justice said Thursday it rejected the request to switch the entry to "inter" or "diverse." It said German family law recognizes only male or female and, although a revision in 2013 does allow people not to be registered as being of either gender, "it did not create a further sex."

Dritte Option, which was involved in preparing the case, said the plaintiff plans to go to Germany's highest court.
