As the U.S. Supreme Court considers whether to hear a challenge to the Affordable Care Act’s contraception mandate, religious groups and employers are blanketing courts with suits that claim the provision is unconstitutional.

The groups argue the mandate violates their religious beliefs by requiring them to provide their employees with health insurance plans that pay for birth control. Religious charities, universities, Christian-owned businesses and others have filed 75 suits across the country against the U.S. Department of Health and Human Services challenging the requirement, according to the Becket Fund for Religious Liberty. The organization represents plaintiffs in 10 cases.
