Setting up another constitutional showdown over the Affordable Care Act, the Supreme Court announced Tuesday it will hear two cases challenging, on religious grounds, the requirement that most employers provide health insurance coverage for contraception including so-called “morning after” methods.

The court will likely hear arguments in the consolidated cases Sebelius v. Hobby Lobby Stores and Conestoga Wood Specialties v. Sebelius in late March, with a decision by the end of June. They are among dozens of cases filed around the country by employers who say their free exercise of religion is violated by the requirement.
