Lori Drew, 49, a neighbor of the dead teen, was to make an appearance in federal court here Monday, accused of one count of conspiracy and three counts of accessing protected computers without authorization to get information used to inflict emotional distress.

The charges were filed in California where MySpace is based. MySpace is a subsidiary of Beverly Hills-based Fox Interactive Media Inc., which is owned by News Corp.

Drew, of suburban St. Louis, allegedly helped create a fake MySpace account to convince Megan Meier she was chatting with a nonexistent 16-year-old boy named Josh Evans.

Megan Meier hanged herself at home in October 2006, allegedly after receiving a dozen or more cruel messages, including one stating the world would be better off without her. Drew has denied creating the account or sending messages to Meier.

Cavel International Inc. closed its plant in DeKalb, Ill., last year after a federal appeals court upheld the ban. The company urged the justices to step in to allow the facility to reopen. The court did not comment on its order Monday.

The plant was the last horse slaughterhouse in the United States. About 40,000 to 60,000 horses were there annually, and most of the meat was shipped to be eaten by diners overseas.

Two other U.S. plants, both in Texas, also closed in 2007.

The lawsuit was filed by Javaid Iqbal, a Pakistani Muslim who spent nearly six months in solitary confinement in 2002. Iqbal, since deported from the United States, says Ashcroft, Mueller and others implemented a policy of confining detainees in highly restrictive conditions because of their religious beliefs and race.

A federal appeals said the lawsuit could proceed, but the Bush administration says the high-ranking officials should not have to answer for the allegedly discriminatory acts of subordinates.

The court ruled 5-4 Monday that someone who is here illegally may withdraw his voluntarily agreement to depart and continue to try to adjust his status while in the United States.

The case involved two seemingly contradictory provisions of immigration law. One allows people to avoid being deported by agreeing to leave the country voluntarily. The advantage to that course is that the wait to get back to the United States is shorter.

The other provision allows immigrants who are here illegally but whose circumstances have changed to make their case to immigration officials. To do that, however, they must remain in the country.

In a unanimous ruling, the justices said Thursday a lower court was wrong to conclude that a vintage airplane buff could not sue for the same documents that were sought by a fellow lover of antique aircraft.

Brent Taylor is executive director of the Antique Aircraft Association and a mechanic who restores vintage airplanes. He sued the Federal Aviation Administration for the plans for an antique F-45 plane.

Taylor filed his lawsuit less than a month after an appeals court issued its ruling against another member of the same organization who sought the same plans.

Government watchdogs and press freedom groups backed Taylor. They worried that government agencies would try to short-circuit efforts by people who request similar records for different reasons.

Liberty Counsel argued that the high court's May 15 ruling put dozens of state laws addressing marriage into conflict and that the Legislature needs time to address those issues.

Barring any further legal intervention, gay couples will be able to start marrying in California at 5:01 p.m. Monday, when the Supreme Court's decision becomes final. The ruling to legalize gay marriage overturned a decision by the Court of Appeal, which is therefore required to issue an order consistent with the high court's 4-3 opinion.

San Francisco City Attorney Dennis Herrera called Liberty Counsel's filing "absurd."

"I am not aware of a process in American law that enables parties to effectively appeal a higher court ruling to a lower court," Herrera said.

Vik Amar, a professor of constitutional law at the University of California, Davis, said it was unlikely the lower court would go against the will of the state Supreme Court.

"It would be an abuse of discretion to ignore the clear statement made by the Supreme Court when they turned down the stay and grant one now," Amar said.

In its third rebuke of the Bush administration's treatment of prisoners, the court ruled 5-4 that the government is violating the constitutional rights of prisoners being held indefinitely and without charges at the U.S. naval base in Cuba. The court's liberal justices were in the majority.

Justice Anthony Kennedy, writing for the court, said, "The laws and Constitution are designed to survive, and remain in force, in extraordinary times."

Kennedy said federal judges could ultimately order some detainees to be released, but that such orders would depend on security concerns and other circumstances.

President Bush was unhappy with the ruling. "We'll abide by the court's decision. That doesn't mean I have to agree with it," the president said during a press conference in Rome. "It was a deeply divided court, and I strongly agree with those who dissented."

Bush also said he would consider whether to seek new laws in light of the ruling "so we can safely say to the American people, 'We're doing everything we can to protect you.'"

It was not immediately clear whether this ruling, unlike the first two, would lead to prompt hearings for the detainees, some of whom have been held more than 6 years. Roughly 270 men remain at the island prison, classified as enemy combatants and held on suspicion of terrorism or links to al-Qaida and the Taliban.
