On June 7, 2018, the Women's Rights Project, the Program on Freedom of Religion and Belief, the ACLU of New Jersey, and Powell & Román, LLC filed an appeal in the U.S. Court of Appeals for the Third Circuit on behalf of Marie Curto, Steve Lusardi, and Diana Lusardi, who faced fines for using their condominium’s pool contrary to the condominium association’s sex-segregated swimming pool hours. The condominium association’s policy limits when residents may use a communal swimming pool based explicitly and exclusively on the residents’ gender, in violation of the Fair Housing Act. The district court upheld the explicitly sex-segregated schedule. On appeal, the Third Circuit reversed the district court's decision.

In January 2018, WRP and the ACLU of Iowa filed an amicus brief with the Iowa Coalition Against Domestic Violence, the National Housing Law Project, National Law Center on Homelessness & Poverty, National Network to End Domestic Violence, and Shriver Center addressing the proper application of Iowa’s Right to Assistance Law. The law protects people who summon emergency assistance from eviction or other landlord- or city-imposed penalties and preempts local crime nuisance ordinances. It was enacted with the advocacy of the ACLU, Iowa Coalition, and others.
