WASHINGTON - The Supreme Court appeared troubled Monday by the selection of the jury that convicted former Enron CEO Jeffrey Skilling as well as the use of a federal fraud law against him. Several justices appeared receptive to arguments by Skilling's lawyer that he did not have a fair trial in Houston, Enron's hometown, following the energy company's 2001 collapse that cost thousands of jobs and billions of dollars. Amid concern that the trial judge spent too little time questioning prospective jurors, Justice Stephen Breyer said, "I'm worried about a fair trial in this instance." Skilling was convicted in 2006 on 19 counts of conspiracy, securities fraud, insider trading and lying to auditors. His lawyers are hoping for a new trial. The court is expected to issue an opinion by late June.
