The reliability of crime labs has been questioned in several states and at the federal level in recent years.

State and federal courts have come to different conclusions about whether recent Supreme Court decisions affirming the constitutional right of a defendant to confront his accusers extend to lab reports that are used in many drug and other cases.

The case the justices accepted, and will consider in the fall, comes from Massachusetts. Luis Melendez-Diaz was convicted of trafficking in cocaine partly on the basis of a crime lab analysis that confirmed that cocaine was in plastic bags found in the car in which Melendez-Diaz was riding.

Rather than accept the report, however, Melendez-Diaz objected that he should be allowed to question the person who prepared it about testing methods, how the evidence was preserved and a host of other issues.

Last week the Delaware Chancery Court ruled that CNet's bylaws do not give it the ability to prevent a group of dissident shareholders led by an affiliate of hedge fund Jana Partners LLC from nominating directors to the company's board or proposing an increase to the board's size.

The court's decision "incorrectly calls into question the bylaws of a large number of companies with the same or similar bylaw provisions," CNet said in a release. The company said its stockholder-approved bylaws are "fully applicable" to the hedge fund.

A "costly and disruptive proxy contest" is not in the best interest of stockholders, and Jana should not be able to seek control of CNet without paying a premium, the company said.

In a letter to CNet Chief Executive Neil Ashe issued earlier Monday, Jana managing partner Barry Rosenstein questioned whether an appeal would benefit shareholders. "We believe it is time for fundamental strategic and operational change at CNet, and that the nominees we have proposed... have the collective experience and expertise to successfully implement this change," he wrote.

Jana had about a 10 percent stake in CNET as of Dec. 31.

But the magic that once made the financially troubled entertainer's 2,500-acre paradise in the rolling hills of central California's wine country one of the most talked-about places on Earth seems to have vanished along with its reclusive owner.

Jackson hasn't been seen in this bucolic area of oak-studded hills since he was acquitted in June 2005 of molesting a 13-year-old visitor to his estate, and his absence leaves the future of Neverland, a sort of Hearst Castle for 12-year-olds, in doubt.

"We're all, of course, wondering what's going to happen. We've heard rumors but we don't know anything," said Kim Morrison, one of the administrators of a private school located just across the road from Neverland.

Attorney General Michael B. Mukasey, who spent most of his adult life as a federal prosecutor and a judge, will return to the courtroom later this month to argue a case before the Supreme Court, officials said yesterday.

Mukasey will urge the justices to reinstate a sentence overturned by an appeals court in the case of Ahmed Ressam, an al-Qaeda operative convicted of a plot to blow up Los Angeles International Airport in 1999.

The last attorney general to handle a case before the high court was Janet Reno in 1996, court officials said. William P. Barr and Richard Thornburgh also argued cases while serving as attorneys general in the administration of George H.W. Bush.

Justice Department spokesman Peter A. Carr said there is a custom, not always followed, for attorneys general to argue at least one Supreme Court case during their term. He declined to comment on why Mukasey chose the Ressam case.

Mukasey, 66, is a retired federal judge who oversaw several high-profile terrorism-related trials while on the bench in New York City. He is scheduled to appear for Supreme Court arguments on March 25 and plans to conduct moot-court sessions to prepare, officials said.

Ressam was arrested near the U.S.-Canada border in December 1999 after customs agents found 124 pounds of explosives in the trunk of his car as he disembarked from a ferry in Port Angeles, Wash. He was convicted in 2001 of nine charges in connection with the plot, but after ceasing cooperation with the FBI was sentenced to 22 years in prison in 2005.

The U.S. Court of Appeals for the 9th Circuit threw out the sentence in 2007 after finding that one of the charges was applied improperly. The federal government disagrees and wants the sentence reinstated.
