Philadelphia ? The city said it will evict a Boy Scout council from its publicly owned headquarters or make the group pay a fair rent price unless it changes its policy on gays.

The Boy Scouts’ Cradle of Liberty Council, the country’s third-largest, has been battling with the city for more than three years over the policy, which like the national Scouts organization forbids gays from being leaders.

City Solicitor Romulo L. Diaz Jr. wrote a letter to William T. Dwyer III, president of the Cradle of Liberty Council, stating that the council’s “discriminatory policies” violate city policy and law, and that city officials have not been assured the group will not discriminate.
