The trustee suing Mets principal owner Fred Wilpon and his family in an attempt to recover alleged profits from Bernard Madoff's Ponzi scheme scored a victory this week. U.S. District Court Judge Jed S. Rakoff granted trustee Irving Picard's request to have the trial, which is set for March 19, heard before a jury. The ruling can be viewed as a victory for Picard from the perspective that a jury might respond differently -- and more unpredictably -- to courtroom arguments than a judge faced with identical circumstances. The Wilpon family previously won a much larger courtroom decision, which reduced their potential liability from $1 billion to $386 million -- and very possibly to $83 million or less.
