The first couple to be issued a same-sex marriage license in Florida sued the state, saying the Bureau of Vital Statistics still won’t allow hospitals to list both same-sex parents on birth certificates.

Cathy Pareto and Karla Arguello of Miami filed the lawsuit in federal court in Tallahassee on Thursday. Pareto and Arguello had twins on Aug. 6. Two other married, same-sex couples also are part of the lawsuit.
