Catholic businesses are challenging the contraceptive rule that requires health care coverage for birth control.
Legatus is a group of Catholic business leaders who have filed the suit in A U.S. District Court in Detroit.
The suit says the law imposes "violations of conscience on Americans who morally object to abortion and contraception."
They are suing the Obama administration to overturn the federal rule included in the president's health care overhaul.
The defendants in the suit are the Departments of Labor, U.S. Treasury, and Health and Human Services.
