The Supreme Court on Monday declined to take up a conservative Christian university's challenge to several key parts of President Obama's health care law.

Liberty University had argued the law's employer coverage requirements, individual mandate and contraception coverage requirements are unconstitutional. The high court didn't comment in dismissing the case, thus leaving in place a federal appeals court ruling that also rejected the Lynchburg, Va., university's lawsuit.

It was the second time in two years the Supreme Court rejected a constitutional challenge to the law's requirement that employers provide affordable health insurance for their workers or face a fine.

In a much more highly anticipated Obamacare dispute, the justices last week agreed to consider whether businesses can use religious objections to get out of an Obamacare requirement to offer employees contraception coverage.

Justices will hear two cases regarding the issue filed separately by the Hobby Lobby craft store chain and Conestoga Wood Specialties Corp. The court said the cases will be combined for arguments, which likely take place in March.

The issue has divided the lower courts, as businesses throughout the country have filed about 40 lawsuits challenging the birth control requirement.
