INDIANAPOLIS (AP) — Two lesbian couples are suing Indiana’s health commissioner and local officials, accusing them of violating their constitutional rights by not listing the names of both of the legally married spouses on their children’s birth certificates.

The U.S. Supreme Court legalized gay marriage in June. But the federal lawsuit says Indiana’s birth certificates still treat marriage as between a man and a woman, without giving equal recognition to married same-sex couples.

The lawsuit filed Monday asks a judge to require that both same-sex parents be named on their children’s birth certificates. It says Indiana’s laws deny those children “the same rights accorded to children born to a married man and woman.”

The Indianapolis Star reports the lawsuit is similar to one filed in February against Indiana and county health departments.
