(ABCNEWS.GO) — Christian owned and operated Hobby Lobby Stores Inc. filed a lawsuit today in U.S. District Court challenging a mandate in the Obama administration’s health care law that requires most employer health insurance plans to provide coverage for contraception and the morning after pill without requiring a co-pay.

There are about 27 lawsuits challenging the mandate, and Hobby Lobby, which owns about 500 arts and crafts stores across the country, is the largest for-profit business to do so.

Several of the lawsuits filed by nonprofit entities have been dismissed, because the rules governing those entities are undergoing revision and won’t take effect until later next year. But Hobby Lobby as a for-profit enterprise, has to comply with the mandate by January.
