The appeals court upheld Vang's convictions for six counts of first-degree intentional homicide and three counts of attempted first-degree intentional homicide, agreeing with his attorneys that there was no merit to an appeal.

The fatal shootings occurred in November 2004 after a group of deer hunters in Sawyer County confronted Vang, 38, of St. Paul, Minn., over trespassing in a tree stand.

Vang, a Hmong immigrant and experienced hunter, testified during his trial that he shot the six white hunters and wounded two more in self-defense, claiming one of them fired a shot in his direction after they shouted racial epithets and cursed at him.

The two survivors testified that Vang had begun walking away from the confrontation when he turned and opened fire.

Prosecutors convinced a jury that Vang reacted in an angry outburst, feeling disrespected by the hunters, and then tried to kill everyone so there would be no eyewitnesses.

Vang, who came to the United States from Laos more than 20 years ago, was sentenced to six consecutive life terms plus 165 years in prison. He is being in kept in an undisclosed prison outside of Wisconsin, according to the state Department of Corrections.

The US Supreme Court refused to review the decision of the US Court of Appeals for the DC Circuit.

A 2005 law, however, allows the detainees to ask the appeals court to check whether the Combatant Status Review Tribunal, created by the Defense Department in 2004, had followed procedures.

During the review tribunals, handcuffed detainees appear without an attorney before three military judges.

Only one person, called a recorder, has access to all elements of a case and presents the documents and witnesses that he or she deems pertinent for the review.

The detainee, meanwhile, can request under certain conditions documents and witnesses, but under such limitations most requests have been rejected.

The government argues that the appeals court can only have access to minutes of the review board hearings and documents presented to the panel.

But detainee attorneys want the court to be able to determine whether the recorder indeed presented all relevant documents for a case and if the military judges were right to reject certain witnesses or documents requested by the detainee.

President George W. Bush's administration has argued that unlawful enemy combatants captured in the "war on terror" do not have the same rights as US criminals or prisoners of war, arguing the detainees are not associated with conventional armies.

Security plans implemented since February by the Multi-National Force - Iraq (MNF-I) have contributed to overcrowding in Iraqi prisons, the Washington Post reported Tuesday. A UN report released in April estimated 20,000 detainees were held in Iraq-run facilities during the month of March, indicating an increase of over 3,500 detainees from the end of January.

Estimates of the number of detainees held in Iraqi-operated facilities are difficult to verify because various ministries operate multiple facilities with little coordination. Deputy Justice Minister Pusho Ibrahim Ali Daza Yei told the Washington Post that the Justice Ministry, which operates prisons for convicted criminals, have provided detention space for untried detainees under the custody of the Iraqi Army and that the military detainees account for over 15 percent of the Justice Ministry's prison population.

An anonymous source told the Washington Post that the "tidal wave of cases" generated by the security plans have overwhelmed the Iraqi justice system, which is mandated by Article 19 of the Iraq Constitution to submit preliminary investigations to "a competent judge in a period not to exceed twenty-four hours from the time the arrest has occurred."

Allegations of detainee abuse, particularly by the Interior Ministry, have also increased as officials have struggled to deal with the influx of detainees. The security plans, formally known as "Operation Law and Order" and commonly referred to as the "troop surge," are intended to increase security and stability in Baghdad and Al Anbar province, and were instituted shortly after Gen. David H. Petraeus assumed command of MNF-I.

Investigators have said the problem comes from tainted wheat gluten imported from China.

The lawsuit, filed in U.S. District Court for the Southern District of Florida on behalf of three cat and dog owners in Michigan and Florida, names 15 food companies and retailers as defendants, including Menu Foods, P&G and Wal-Mart Stores Inc.

In a press release, the law firm said the companies have spent $300 million a year in marketing campaigns that misrepresent the contents of their pet foods.

According to court documents, the 34-year-old Rock told police she shot 36-year-old Kenneth Walkinshaw at their home in March after he complained about how bad his life was.
