Residents of Puerto Rico who say they are “nonbinary” will now be permitted to have an identifier on their birth certificates.

The Supreme Court of Puerto Rico ruled on May 30 that nonbinary people have a right to differentiate themselves from “binary” people and could now choose “X” for their gender on their birth certificates. The decision stemmed from a lawsuit filed by six people in Puerto Rico seeking to change their birth certificates’ genders because they believed it did not align with their gender identities, according to Fox News.
