Indiana Attorney General Todd Rokita is leading a 16-state coalition defending the right of Roncalli High School to uphold church teachings on same-sex marriage in its hiring and firing decisions.

On Tuesday, Rokita filed an amicus brief in support of Roncalli and the Archdiocese of Indianapolis.

Roncalli is a Catholic High School in Indianapolis.

A former guidance counselor in a same-sex marriage filed a lawsuit against Roncalli and the Archdiocese after Roncalli decided to not renew her contract.

In August, a federal district court ruled in Roncalli’s favor.

That former counselor filed an appeal in the 7th U.S. Circuit of Appeals.
