Yet another lawsuit by a for-profit small business challenging the Affordable Care Act contraceptive coverage mandate was filed Monday-- this time by a Missouri-based plumbing products corporation and its Catholic owners. The complaint (full text) in Sioux Chief Mfg. Co., Inc. v . Sebelius, (WD MO, filed 1/14/2013), contends that the mandate violates plaintiffs' rights under the 1st and 5th Amendments, the Religious Freedom Restoration Act, and the Administrative Procedure Act. Alliance Defending Freedom issued a press release announcing the filing of the case.
