WILMINGTON, Del. — A Delaware judge has refused to fast-track a trial on billionaire investor Carl Icahn’s claims that Dell Inc. directors have breached their fiduciary duties in scheduling a vote on founder and CEO Michael Dell’s bid to take the embattled computer maker private.

Dell’s board has scheduled a shareholder vote on Michael Dell’s $24.8 billion buyout offer for Sept. 12, followed by an overdue annual meeting on Oct. 17. Icahn wanted the merger vote and annual meeting held the same day.
