The Becket Fund for Religious Liberty says the Obama administration's most recent modification of its birth control mandate is "more of the same."
The Becket Fund represents eight religious employers in their cases against the mandate.
More than 200 plaintiffs have filed 61 challenges to the portion of the health care law that forces employers to purchase birth control coverage for their employees.
After faith-based groups objected, the administration pledged to compromise. But the Becket Fund said the latest plan is unlikely to satisfy their objections and the cases will have to be resolved in court.
