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.
