Court arguments over Oklahoma's ban on same-sex marriage will center on whether voters singled out gay people for unfair treatment when they overwhelmingly defined marriage as a union between one man and one woman.

Judges at a federal appeals court in Denver will hear arguments Thursday from lawyers representing a couple challenging Oklahoma's ban and the Tulsa County clerk who refused to grant them a license. The judges heard a similar case from Utah last week.

Oklahoma voters approved the ban in 2004 by a 3-1 margin. The Tulsa couple tried to obtain a marriage license shortly afterward.

A federal judge overturned the ban in January, saying it violated the equal-protection clause of the U.S. Constitution. Lawyers for the state say voters have a right to set their own laws.

A federal appeals court on Thursday reinstated a shareholders lawsuit filed against BP Alaska in the wake of two oil spills in 2006 on the North Slope that exposed problems with the company's pipeline maintenance program.

A three-judge panel of the 9th U.S. Circuit Court of Appeals reversed the U.S. District Court of Western Washington on several claims.


Shareholders sued BP in 2008, claiming management made misleading statements about the conditions of the company's pipelines, and its maintenance and leak detection program after the first spill of 200,000 gallons onto the North Slope tundra two years earlier. The lawsuit claims BP made the statements knowingly or with deliberate recklessness.

The shareholders claim BP's share price fell 4 percent after the second spill five months later and the subsequent field shutdown for maintenance.

The Associated Press left messages seeking comment for attorneys on both sides of the case.

BP spokeswoman Dawn Patience said in an emailed statement that the company had not had an opportunity to study the decision, so "it would not be appropriate to comment."

BP Exploration Alaska Inc. was fined $20 million in 2007 after pleading guilty to a federal environmental crime for failing to prevent the crude spill, the largest ever at Prudhoe Bay.

The problems became known after the March 2006 spill prompted the FBI and the Environmental Protection Agency to open an investigation into maintenance practices at the 30-year-old field.

They found that thick sludge caked along the bottom of the leaky pipe was protecting colonies of bacteria that produce a corrosive acid. The acid had eaten an almond-sized hole in the steel over the course of several years, and that's where the spill occurred.

A person's legal status in the country can't be used in civil cases by attorneys to intimidate or coerce under a new rule approved by the Washington Supreme Court last week.

Since 2007, advocates have been working to make the change to the Rules of Professional conduct that attorneys licensed in the state must adhere to following. The lobbying began after members of the Latino/a Bar Association of Washington had seen attorneys and, in some cases, judges discuss a person's legal status in the country openly in court to intimidate.

"We thought it was unethical to do," said Lorena Gonzalez, who was president of the attorney association at the time. "We looked at the rules there was silence on the issue."

The rule does not affect criminal cases, but does cover civil matters, such as family disputes, personal injury claims, workplace cases, medical malpractice and other fields.

The Illinois Supreme Court ended a lengthy and emotionally charged legal appeal over an abortion notification law Thursday, clearing the way for the state to begin enforcing a 1995 measure that requires doctors to notify a girl's parents 48 hours before the procedure.

The court ruled unanimously to uphold a circuit court's earlier dismissal of a challenge to the law that was filed by a Granite City women's health clinic and a doctor at the University of Illinois at Chicago.

After court battles that lasted nearly two decades, Illinois now joins 38 other states in requiring some level of parental notification. The law goes into effect in 35 days unless it's appealed to the U.S. Supreme Court, which has found such laws to be constitutional elsewhere.

Opponents of the notification law had argued that it violated privacy and gender equality rights because young women should be able to make their own decisions about their bodies and pregnancies. Supporters of the law, which was defended by the Illinois Attorney General's office, argued that parents would be deprived of basic rights if they were not notified of a daughter's decision to have an abortion.

Anti-abortion activists have long said Illinois was a haven for teens from states with stricter laws on the books seeking abortions.

Gov. Tom Corbett plans to nominate state appeals court Judge Correale Stevens to temporarily fill a vacancy on the state Supreme Court.

Two people familiar with the decision told The Associated Press of Corbett's plans on condition of anonymity, saying the information was part of private conversations.

The decision comes more than a month after the opening was created following the resignation from the bench of Joan Orie Melvin. Melvin was convicted of using public employees to help her political campaigns.

Stevens will require a two-thirds approval by the state Senate to take a seat on the bench.
   
Stevens is a familiar face in state politics and government, and is currently president judge of state Superior Court, which handles criminal and civil appeals. His long career in public service also includes time as Luzerne County's district attorney, a county judge and seven years as a state representative.

Melvin and Stevens are both Republicans, so if he is confirmed the court will return to a four-to-three Republican majority.

A special U.S. Senate election to replace the late Democratic Sen. Frank Lautenberg can be held in October, as it was scheduled by Republican Gov. Chris Christie, a state court ruled Thursday.

The ruling could be appealed. And while it keeps an election on course it does not seem likely to chill criticism of the popular governor for how he chose to replace Lautenberg, the Senate's oldest member, who died last week at age 89.

Four Democrats and two Republicans have filed petitions to run in the Senate race to complete Lautenberg's term, with three early polls showing Democratic Newark Mayor Cory Booker as the front-runner.

Christie scheduled the election for Oct. 16. A group of Democrats sued, saying it should be held Nov. 5, the day voters are going to the polls in the general elections anyway.

Christie's critics have complained that holding the election in October will cost taxpayers unnecessarily. Officials say each election costs the state about $12 million to run.

Judge Jane Grall wrote Thursday that objections to the costs of the election are policy matters that aren't questions for the court.
