The justices typically avoid cases about judicial ethics, but they agreed to review the actions of a West Virginia Supreme Court justice whose vote overturned a $50 million verdict against a company that is run by the most generous backer of his election.

The high court's decision comes amid growing concern over the role of money in electing state judges. Campaign spending on state supreme court elections rose by 25 percent to nearly $20 million from 2006 to 2008, a national justice reform group said.

Don Blankenship, the chief executive of Massey Energy Co., spent more than $3 million to help elect Justice Brent Benjamin to the West Virginia high court. Benjamin twice was part of 3-2 majorities that threw out a verdict in favor of Harman Mining Co. in its coal contract dispute with Massey.

Harman said Benjamin's participation in the case created an appearance of bias strong enough to violate its constitutional rights.

The American Bar Assocation and other legal ethics groups have taken Harman's side.

In earlier cases, the Supreme Court has said that judges must avoid even the appearance of bias.

Benjamin repeatedly rejected calls to recuse himself from the case when it was before the state high court. He has since said that he fairly judged the dispute.

Benjamin issued a lengthy defense of his actions, pointing out that he had no financial interest in the outcome of the case and the campaign money went to an independent group, not his campaign. He had no comment Friday after the court accepted the case for review.

Massey vice president and general counsel Shane Harvey said, "We are confident that the Harman case was properly decided by the West Virginia Supreme Court."

David Fawcett, a Pittsburgh attorney who represents Harman and its founder, Hugh Caperton, said, "The question at issue here is central to the future of our court system." Former Solicitor General Theodore Olson will argue the case for Caperton at the Supreme Court, probably in March or April.

Retired Supreme Court Justice Sandra Day O'Connor has not commented on the West Virginia dispute, but she has bemoaned the role of money in state judicial elections.

"There is too much special interest money and influence in state court elections," O'Connor said recently. "It endangers the public's faith in the justice system. If courts are going to stay impartial, leaders in every state need to get moving on reforms."

Former Colorado Supreme Court Justice Rebecca Love Kourlis, an advocate for ending partisan election of judges, said the case may get "people to pay attention to the problems partisan fundraising creates." Kourlis is executive director of the Institute for the Advancement of the American Legal System at the University of Denver, which provided the figures on spending in judicial elections.

The Supreme Court case stems from a jury verdict in 2002 that concluded Richmond, Va.-based Massey hijacked a coal supply contract from Harman, plunging both it and Caperton into bankruptcy.

Massey contended Harman filed for bankruptcy because of mounting losses at a mining facility and other problems that had nothing to do with Massey.

The case is Caperton v. Massey, 08-22.

In a 6-0 decision, the court said the fees permitted under the 1999 Check Cashers Act were really triple-digit interest rates. The state constitution limits interest rates on loans to 17 percent.

"Because that fee is in reality an amount owed to the lender in return for the use of borrowed money, we must conclude that the fees authorized clearly constitute interest," Justice Paul Danielson wrote.

Through a payday loan in Arkansas, a customer writing a check for $400, for example, typically would receive $350. The lender would keep the check for about two weeks before cashing it.

The customer could buy back the check for $350 during that two-week period, but otherwise would pay the full $400 when the company cashed his check. The $50 charge on a $350 loan for 14 days equates to 371 percent, well above Arkansas' usury limit.

Attorney Todd Turner, who represented the plaintiffs who challenged the Check Cashers Act, said the ruling means it will be impossible for payday lenders to operate in the state.

"It's great for all the Arkansas residents who have been paying 600 percent for these loans," Turner said.

Tom Hardin, attorney for the Arkansas Financial Services Association that sought to preserve the law, did not immediately return a call seeking comment.

Even before Thursday's ruling, the number of payday lenders in the state has dwindled in response to threats of lawsuits from Attorney General Dustin McDaniel. An advocacy group said in a report last month that the number of payday lenders operating in the state has dropped from 237 in March to just 33.

In its 6-0 decision, the court overturned a Pulaski County judge who last year ruled that the 1999 act was constitutional.

The request came at a meeting of Cup contenders Thursday called by Alinghi at its home yacht club in Geneva.

Preparations for the 33rd America's Cup have been stalled for more than a year by legal problems.

The BMW Oracle team based in San Francisco believes Alinghi has acted unfairly in the way it has drawn up rules for the next cup races.

The team is waiting on an appeal ruling from a New York court.

Swiss-owned Alinghi has invited teams from across the world to help it plan for an America's Cup in 2010. On Thursday they united to ask BMW Oracle to join them.

Social issues so volatile that the presidential campaigns sidestepped them will be on the ballots in several states next week, including measures that would criminalize most abortions, outlaw affirmative action and ban same-sex marriage in California, one of only three states that allows it.

In all, there are 153 proposals on ballots in 36 states.

In Washington, voters will decide whether to join Oregon as the only states offering terminally ill people the option of physician-assisted suicide. Massachusetts has three distinctive measures on its ballot — to ban dog racing, ease marijuana laws and scrap the state income tax, a step that could unleash budgetary tumult.

The main presidential rivals, Democrat Barack Obama and Republican John McCain, have rarely made proactive comments during the campaign about same-sex marriage or affirmative action — issues on which the public is deeply divided. Abortion also has seemed like an uncomfortable topic for them at times, although Obama makes clear he supports abortion rights and McCain says he would like to ban most abortions.

But in a half-dozen states, these three issues are front and center.

Because Missouri defines work product in criminal procedure only in regard to the attorney's opinions, theories or conclusions, the Missouri Supreme Court found that because grand jury proceedings do not take place before an indictment is filed, the discovery rules for criminal proceedings do not apply.

"Historically, a lawyer is an officer of the court and is bound to work for the advancement of justice while faithfully protecting the rightful interests of his clients," Judge Patricia Breckenridge wrote. "In performing his various duties, however, it is essential that a lawyer work with a certain degree of privacy, free from unnecessary intrusion by opposing parties and their counsel. Proper preparation of a client's case demands that he assemble information, sift what he considers to be the relevant from the irrelevant facts, prepare his legal theories and plan his strategy without undue and needless interference. ... Were such materials open to opposing counsel on mere demand, much of what is now put down in writing would remain unwritten. An attorney's thoughts, heretofore inviolate, would not be his own. Inefficiency, unfairness and sharp practices would inevitably develop in the giving of legal advice and in the preparation of cases for trial. The effect on the legal profession would be demoralizing. And the interests of the clients and the cause of justice would be poorly served."

Miliband now has a week to decide whether to comply with the order to release of the documents pertaining to Binyam Mohamed's detention. The British government has argued the release of the documents could compromise national security, and it could appeal the court order.

The High Court made the ruling in the case of Mohamed, who was captured in Pakistan in April 2002 and accused of conspiring with al-Qaida leaders to attack civilians. His lawyers say the British government is withholding information about his treatment in U.S. custody which is critical to his hope of receiving a fair trial.

"The information held by the foreign secretary is not merely necessary, but essential, if Binyam Mohamed is to have his case fairly considered," Judge John Thomas wrote in the 75-page judgment.

Mohamed claims he was transferred illegally from Pakistan to Morocco after his arrest and alleges he was tortured during his 18 months in detention. Neither the United States nor Britain has disclosed any information about his time in custody until he arrived at Guantanamo Bay in 2004.
