WASHINGTON (AP) — Another case related to President Barack Obama's health care law is before the Supreme Court this week.

At issue is whether the religious rights of employers trump the rights of women to the birth control of their choice.

The court is hearing arguments tomorrow in a religion-based challenge from family-owned companies that object to covering certain contraceptives as part of the law's preventive care requirement.

The companies are willing to cover most methods of contraception, as long as they can exclude drugs or devices that the government says may work after an egg has been fertilized.

The largest company among them, Hobby Lobby Stores Inc., and the Green family that owns it, say their religious beliefs forbid them to sell such contraceptives.

The administration says a victory for the companies would prevent women from making decisions about birth control based on what's best for their health.
