The Supreme Court has ruled against the estate of Anna Nicole Smith in its quest to capture some of the $1.6 billion estate left behind by her late Texas billionaire husband.

The high court on Thursday ruled that a bankruptcy court's decision to give the now-deceased Playmate $475 million from the estate of oil tycoon J. Howard Marshall was decided incorrectly.

Smith and Marshall were wed in 1994, and he died the next year.

His will left his estate to his son, E. Pierce Marshall, and nothing to Smith. A California bankruptcy court awarded Smith part of the estate, but the 9th U.S. Circuit Court of Appeal said that a bankruptcy court could not make a decision on an issue outside of bankruptcy law.

A $188 million class-action verdict against Wal-Mart Stores Inc. and Sam's Club over payment to employees for rest breaks and off-the-clock work was upheld Friday by a Pennsylvania appeals court.

A three-judge Superior Court panel said there was sufficient evidence at trial to conclude there had been a breach of contract, unjust enrichment and violations of state labor laws.

The judges also ruled in a 211-page opinion that the presiding Philadelphia judge erred in determining some of the plaintiffs' legal fees, and sent that part of the case back for recalculation.

The 2006 trial, which lasted 32 days, resulted in a finding that Wal-Mart did not pay employees for all the work they performed and did not let them take their paid, mandatory rest breaks, the judges wrote. The court awarded $46 million in attorneys' fees.

Wal-Mart spokesman Greg Rossiter said the retail giant believes the court decision was wrong in a number of respects and looks forward to additional review in the courts.

Southwest Virginia landowners have reached a $3.4 million tentative settlement in a class-action lawsuit over coalbed methane rights.

The Bristol Herald Courier reports Wednesday's settlement would be split among 1,850 landowners.

The federal lawsuit alleged that Chesapeake Energy Corp. subsidiary Chesapeake Appalachia underpaid royalties to landowners for decades.

The settlement will be made final at a hearing Oct. 4.

Other similar class-action lawsuits are pending in federal court in southwest Virginia involving CNX Gas Co. and EQT Production Co.

The Supreme Court has refused to get involved in a long-running dispute on the continued existence of the Yankton Sioux Tribe and the extent of its lands in South Dakota.

The justices on Monday let stand several rulings involving the tribe, including an appeals court decision saying the reservation covers more than 30,000 acres, which is mostly land the federal government holds in trust for the tribe and individual tribal members.

The high court also rejected an appeal from the tribe to block the transfer of two federal recreation areas along the Missouri River to the state of South Dakota.

The cases are Daugaard v. Yankton Sioux Tribe, 10-929; Southern Missouri Recycling v. Yankton Sioux Tribe, 10-931; Hein v. Yankton Sioux Tribe, 10-932; and Yankton Sioux Tribe v. Daugaard, 10-1058.

The Supreme Court on Monday blocked a massive sex discrimination lawsuit against Wal-Mart on behalf of women who work there.

The court ruled unanimously that the lawsuit against Wal-Mart Stores Inc. cannot proceed as a class action, reversing a decision by the 9th U.S. Circuit Court of Appeals in San Francisco. The lawsuit could have involved up to 1.6 million women, with Wal-Mart facing potentially billions of dollars in damages.

Now, the handful of women who brought the lawsuit may pursue their claims on their own, with much less money at stake and less pressure on Wal-Mart to settle.

The justices divided 5-4 on another aspect of the ruling that could make it much harder to mount similar class-action discrimination lawsuits against large employers.

Justice Antonin Scalia's opinion for the court's conservative majority said there needs to be common elements tying together "literally millions of employment decisions at once."

But Scalia said that in the lawsuit against the nation's largest private employer, "That is entirely absent here."

Justice Ruth Bader Ginsburg, writing for the court's four liberal justices, said there was more than enough uniting the claims. "Wal-Mart's delegation of discretion over pay and promotions is a policy uniform throughout all stores," Ginsburg said.

Business interests lined up with Wal-Mart while civil rights, women's and consumer groups have sided with the women plaintiffs.

William Chandler III never realized his young man's dream of becoming a university professor, yet he has managed to pass on plenty of lessons to students of American law and business.

Chandler, 60, is retiring this week as head of Delaware's Court of Chancery, which rules over corporate law in a state that is the legal home to more than half of all publicly traded U.S. companies, including about two-thirds of the Fortune 500.

Chandler's decision to join a Silicon Valley-based law firm, where he will focus on advising corporate clients and working behind the scenes on litigation strategy, comes after 26 years on the bench, including eight years as a vice chancellor on the five-member court and 14 as chancellor.

But Chandler, who also served as a Superior Court judge before being appointed a vice chancellor, never envisioned himself wearing a black robe.

After obtaining his law degree from the University of South Carolina and clerking for a federal judge in Wilmington, Chandler went to Yale University law school with his eye on a master's degree and a dream of becoming a professor.
