Updated from 1:10 p.m. ESTThe judge hearing larceny and fraud charges against former Tyco ( TYC) executives Dennis Kozlowski and Mark Swartz declared a mistrial Friday, as controversy surrounding a holdout juror made it impossible to carry on. The decision, announced Friday by judge Michael Obus in New York state Supreme Court in Manhattan, brought a circus conclusion to the case and the second high-profile mistrial for prosecutors trying to clean up white-collar crime on Wall Street. In October 2003, the obstruction of justice trial of former Credit Suisse First Boston banker Frank Quattrone also ended in a hung jury. "I've been doing this 40 years," said Charles Stillman, Swartz's lawyer. "If I piled up all the experiences top to bottom, I ain't seen anything like this yet." Kozlowski and Swartz were accused of pocketing $600 million through unauthorized bonsues and illegal stock sales. Kozlowsi, along with WorldCom's Bernard Ebbers and Enron's Kenneth Lay and Jeffrey Skilling, became a symbol for the excess that went along with a string of corporate scandals that came to light on Wall Street over the last three years. Legal observers said the mistrial proved the adage that defense lawyers don't necessarily have to win, just not lose. "That's a great victory for the defendants and their attorneys," said Stephen Ryan, a former federal prosecutor, now a partner at Manatt, Phelps & Phillips in Washington. "This trial is a win for the defense, there's just no doubt about that. If you're not going to jail, it's that simple." Defense attorneys appealed to Obus on Monday for a mistrial after newspapers printed the name of a female juror believed to be the one holdout against conviction. She was identified after appearing to flash an "OK" hand signal toward the defendants during a courtroom meeting last week. Published reports Friday afternoon said the juror subsequently received a threat, and quoted the judge saying that while he found the hand gesture "equivocal," he had no choice but to end the six-month-old proceeding. "It appears a great misservice has been done to her and her family," he was quoted saying about the juror. While lawyers commenting on the case said any number of factors could contribute to a mistrial, they agreed the level of media scrutiny directed at the apparent holdout juror was without recent precedent.
