Members from both congressional parties, women's groups, doctors, scholars, states and religious groups filed 56 amicus briefs, asking the court to rule in favor of Hobby Lobby when it hears the case in March.
Sebelius v. Hobby Lobby will focus on a provision of the healthcare law that says that most employers that provide health insurance have to cover preventive health benefits, such as contraception.
But Hobby Lobby, the Oklahoma City-based chain of arts and crafts stores, has argued that insuring contraception for its employees violates the religious beliefs of its founder and CEO, David Green. Asking to be excluded from this piece of the law, Hobby Lobby won its case in the 10th Circuit Court of Appeals in June. HHS is appealing the ruling, which the Supreme Court will decide on before its term ends in June.
