The Supreme Court is poised to deliver its verdict in a case that weighs the religious rights of employers and the right of women to the birth control of their choice.

The court meets for a final time Monday to release decisions in its two remaining cases before the justices take off for the summer.

The cases involve birth control coverage under President Barack Obama's health law and fees paid to labor unions representing government employees by workers who object to being affiliated with a union.

Two years after Chief Justice John Roberts cast the pivotal vote that saved the health care law in the midst of Obama's campaign for re-election, the justices are considering a sliver of the law.

Employers must cover contraception for women at no extra charge among a range of preventive benefits in employee health plans.

Dozens of companies, including the Oklahoma City-based arts and crafts chain Hobby Lobby, claim religious objections to covering some or all contraceptives.

The court reinstated the class-action lawsuit against Grain Processing Corp., which operates a plant that turns corn kernels into products ranging from corn syrup to ethyl alcohol. The plaintiffs' claims of nuisance, negligence and trespass are not barred by the federal Clean Air Act or state rules governing air emissions, Justice Brent Appel wrote in a 6-0 decision that was applauded by environmentalists but criticized by business interests.

A regional economic force, the company buys $400 million in corn from farmers annually and is one of the area's largest employers.

But Muscatine residents have complained for years that it spews harmful chemicals into the environment that get blown onto their homes, yards and cars. The lawsuit, filed on behalf of up to 17,000 residents who live within a 3-mile radius of the plant, contends the pollution undermines their ability to enjoy their property and causes metals in everything from swing sets to air conditioning systems to corrode.
