The court will hear arguments in the fall in the case of Cesar Sarausad II. He was convicted for his role as the driver in the shooting in which Melissa Fernandes, 16, was killed and Brent Mason, 17, was wounded outside a Seattle high school on March 23, 1994.

The 9th U.S. Circuit Court of Appeals in San Francisco overturned the conviction because of faulty jury instructions.

In his instructions to the jury, Judge Larry A. Jordan said Sarausad could be convicted of murder regardless of whether he knew of any plan for a killing. The appeals panel ruled that the jury should have been told Sarausad could be convicted of murder only if he knew what was being planned.

The state of Washington asked the Supreme Court to reinstate the conviction, which had been upheld by state appeals courts.

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.
