A local Boy Scouts chapter embroiled in a battle over gay rights is suing the city of Philadelphia to avoid eviction from their headquarters, Delaware Online reports.

The federal lawsuit seeks to stop the city from evicting the Scouts or from charging the group about $200,000 a year in rent. The Scouts currently pay $1 annually for the space.

The city says it cannot keep subsidizing the rent of a private group that discriminates. It gave the Scouts until Saturday to revise their policy or pay rent.

The U.S. Supreme Court ruled in 2000 that the Boy Scouts, as a private group, have a First Amendment right to bar gays.

The Philadelphia chapter adopted a nondiscrimination policy in 2003, but was ordered to revoke it by the National Council.
