A Dutch court on Monday allowed for the first time a person to be registered as neither a man nor a woman but as a "third gender."
The Limburg District Court in Roermond ruled that the unnamed plaintiff can now be recorded in the Dutch birth register as "gender undetermined" as opposed to male or female.
"At birth in 1961, this person's gender could not be determined and the parents decided to register the person as male, to make things easier at the time," the court said in a statement.
In 2001 however, the plaintiff underwent medical treatment and changed gender to female.
"Eventually it also turned out that the female gender did not fit the person, whose personality is experienced as gender-neutral," the court said, "feeling neither like a man nor a woman."
The plaintiff then asked authorities to include a third, gender-neutral entry in the birth register.
A similar request by a different person was turned down in 2007 by the Netherlands' highest court, the High Council.
But due to "social and legal developments, the time is ripe for the recognition of a third gender," the judges said.
"To enable the registration of a third gender "X", a legal amendment is crucial. It's now up to the lawmakers," they added.
Meanwhile "the court rules in favor of changing the person's gender in the birth register to 'gender could not be determined'," the judges said.
