Victims of Bernard Madoff's fraud cannot pursue a Florida lawsuit to recover $11 billion from the estate of Jeffry Picower, who they say helped perpetuate the swindler's Ponzi scheme, a Manhattan bankruptcy judge ruled on Wednesday.

U.S. Bankruptcy Judge Stuart Bernstein said the lawsuit by A&G Goldman Partnership and Pamela Goldman, their third effort to sue in Florida, violated an injunction barring Madoff victims from pursuing claims belonging to Irving Picard, the trustee liquidating Bernard L. Madoff Investment Securities LLC.

A spokeswoman for Picard declined to comment. Lawyers for the Goldman parties were not immediately available for comment. Bernstein oversees the Madoff firm's liquidation.

Picard had in December 2010 won a $7.2 billion settlement with the estate of Picower, who died in October 2009.

But a slew of litigation ensued from Madoff customers, including many who say the trustee undervalued their claims, against Picower and other alleged enablers of Madoff.

Picard has estimated that Madoff's victims lost $17.5 billion in the fraud, which was uncovered in December 2008.

In the latest Florida case, the Goldman parties added claims that Picower "propped up" Madoff's fraud with $200 million of loans to fund investor redemptions, and agreed to serve in trading records as a counterparty for many fake options trades.

The Goldman parties sought to hold Picower responsible for "all $18 billion" of Madoff customers' losses, less the $7.2 billion from the 2010 settlement.

Bernstein nevertheless found it "wholly conclusory" to allege that Picower helped Madoff distribute fake statements to customers, and had enough "control" over the swindler to justify separate litigation.

He also said allowing the Florida lawsuit "would carry real risks" to the Madoff firm's bankruptcy estate, encouraging more lawsuits and perhaps undermining the $7.2 billion accord.
