The

U.S. Supreme Court

left the

Microsoft

(MSFT) - Get Report

case for another day, giving no indication in an order list released Friday whether it will hear the company's appeal of an historic antitrust verdict and breakup order.

The court, which reconvenes on Oct. 2, could issue an order any time it chooses. In its third and final summer order list, released Friday, the court granted one petition but left the Microsoft

case untouched. Last year, the court granted a few petitions in its final summer list.

The next order list is scheduled to be released Oct. 2. The court's next private conference is Sept. 25. It can release miscellaneous orders whenever it chooses.

Microsoft is trying to steer its appeal to the

U.S. Circuit Court of Appeals for the District of Columbia

, but federal prosecutors have invoked an obscure 1974 law known as the

Expediting Act

to send the company's appeal directly to the Supreme Court. A three-judge panel of the court of appeals, in a related case, issued an important ruling in Microsoft's favor two years ago.

The court could decide at any time whether to hear the appeal or remand it to the lower court, which has indicated it is ready to quickly review the case as a full panel, rather than as a three-judge panel.

A federal district judge ruled on June 7 that the company illegally used its monopoly position to compete unfairly and ordered it split in two.

Microsoft finished Friday regular trading down 75 cents, or 1%, at $69.31.
