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 is entering a $40 million dispute between an energy company and Montana that could turn on the experiences of the Lewis and Clark expedition.

The justices said Monday they will hear an appeal from PPL Montana of a state court decision ordering the company to pay $40 million in rent for placing its hydroelectric dams in riverbeds owned by the state.

The ownership of the waterways turns on whether they were navigable when Montana became a state in 1889. Both the company and the state base part of their argument on the journey of Meriwether Lewis and William Clark more than 200 years ago.

The Supreme Court will let two West Virginia residents revive a lawsuit against Bayer AG over its anti-cholesterol drug Baycol, which was withdrawn from the market in 2001 after reports of a severe and sometimes fatal muscle disorder.

The high court on Thursday unanimously agreed to let Kevin Smith and Shirley Sperlazza's class-action lawsuit against Bayer go forward.

The 8th U.S. Court of Appeals had thrown out their lawsuit out after a federal judge overseeing multistate litigation against Bayer refused to let other West Virginians file a similar class-action lawsuit against the corporation.

The high court said that decision was incorrect.

The second trial to result from a massive investigation into insider trading at hedge funds ended Monday with the conviction of a trio of Wall Street traders on charges they paid hefty bribes to coax confidential information out of shady lawyers.

A jury reached the verdict against stock trader Zvi Goffer and two others in federal court in Manhattan after deliberating five days since June 2. It came a month after the conviction of Raj Rajaratnam, the one-time billionaire who founded the Galleon Group of hedge funds and who was once Goffer's boss.

Goffer, his brother Emanuel and Michael Kimelman were convicted of conspiracy to break securities laws. The men were permitted to remain free on bail pending sentencing, set for the fall.

The defendants, who had insisted they based trades only on public information, remained calm during the verdict. Zvi Goffer's wife and mother left the courtroom in tears.

The Supreme Court has rejected an appeal from investment funds seeking repayment of their losses in a $3.7 billion Ponzi scheme operated by Minnesota businessman Thomas Petters.

The funds together lost $165 million and challenged a federal judge's order denying restitution to any of Petters' victims. Among other things, the court said the victims would have other ways of recouping some of their money.

The justices on Monday refused to disturb the ruling.

A federal law generally requires a court to order restitution as part of a defendant's sentence, but allows for some exceptions. The judge in this case said that restitution would be too complex, take too long and result in the payment of less than a penny for each dollar victims lost.

A Yemeni detainee ordered to be freed from Guantanamo Bay has to stay now that a U.S. appeals court has overturned his release.

The U.S Court of Appeals in Washington says circumstantial evidence of terrorist ties can be enough to keep a prisoner like Hussain Salem Mohammad Almerfedi at the U.S. naval prison in Cuba.

Almerfedi was captured in Iran after the Sept. 11, 2001 attacks and eventually transferred to U.S. authorities through Afghanistan. Government attorneys argue he was staying at an al-Qaida-affiliated guesthouse, based on the testimony of another Guantanamo detainee. Almerfedi denied it, and a lower court judge found the testimony against him unreliable and ordered him released.

But the appeals court said the judge erred in finding the testimony unreliable and found it was likely Almerfedi was part of al-Qaida.
