What is the issue the SCOTUS will decide in Burwell v. Hobby Lobby (June 30, 2014)?

from SCOTUS BLOG page: Issue: Whether the Religious Freedom Restoration Act of 1993 (RFRA), 42 U.S.C. §§ 2000bb et seq., which provides that the government “shall not substantially burden a person’s exercise of religion” unless that burden is the least restrictive means to further a compelling governmental interest, allows a for-profit corporation to deny its employees the health coverage of contraceptives to which the employees are otherwise entitled by federal law, based on the religious objections of the corporation’s owners. http://www.scotusblog.com/case-files/cases/sebelius-v-hobby-lobby-stores-inc/
