On Jan. 22, 2021, CLINIC, along with the U.S. Conference of Catholic Bishops and Catholic Charities USA, filed an amicus brief with the U.S. Supreme Court, condemning the misnamed "Migrant Protection Protocols," or MPP, as unlawful and contrary to Catholic Social Teaching. The brief, filed in Wolf v. Innovation Law Lab, urges the Court to uphold the Ninth Circuit Court of Appeals decision which found that MPP was not authorized under the Immigration and Nationality Act.
