U.S. District Judge Lawrence Zatkoff ruled Sunday in favor of Tom Monaghan and his Domino's Farms Corp., near Ann Arbor. Monaghan, a devout Roman Catholic, said contraception isn't health care but a "gravely immoral" practice.
Zatkoff granted Monaghan's emergency motion for a temporary restraining order until a final decision is made in the case. The mandate would have taken effect Tuesday.
The government said the contraception mandate benefits women's health and removes financial barriers. There are about a dozen similar lawsuits pending nationwide.
Monaghan sold most of his controlling stake in Domino's Pizza in 1998 to private equity company Bain Capital.
