NEW YORK — Peter K. Leisure, a federal judge in Manhattan who oversaw high-profile business disputes, trials of Mafia chieftains and political controversies in 26 years on the bench, died on Tuesday in Manhattan. He was 84.
The cause was complications of pneumonia, according to his longtime judicial assistant, Gloria Rider.
In 1986, Judge Leisure oversaw the antitrust jury trial pitting the upstart United States Football League against the National Football League. The USFL, which claimed that the NFL had established a monopoly and persuaded television networks not to broadcast USFL games, won a partial victory but was awarded only $1 in damages.
He also presided over the 1993 racketeering and drug trial that led to the convictions of three members of the Gambino crime family. Full story for BostonGlobe.com subscribers.
