Dec 15 (Reuters) - The trustee handling the liquidation ofthe brokerage unit of Lehman Brothers Holdings Inc filed apetition with the U.S. Supreme Court on Monday seeking review ofthe business's cash assets awarded to Barclays Plc.
Lehman, once Wall Street's fourth-largest investment bank,had $639 billion of assets when it filed for Chapter 11protection in September 2008. The British bank won courtapproval to buy much of Lehman's brokerage business.
Trustee James Giddens, who has been seeking to recoup moneyfor the brokerage's creditors, said lower court rulings grantingmargin assets to Barclays breached bankruptcy rules.
Barclays declined to comment. The bank's shares closed down3 percent on the London Stock Exchange on Monday.
A federal appeals court ruled in August that Barclays wasentitled to about $6 billion of disputed assets.
These include $4 billion of margin assets held by thirdparties to support a Lehman exchange-traded derivativesbusiness, and $1.9 billion of so-called clearance box assetsused to process securities trades.
U.S. Bankruptcy Judge James Peck said in 2011 that Barclayswas entitled to the clearance box assets, but not the marginassets. District Judge Katherine Forrest, however, said in 2012that Barclays deserved both. (Reporting by Amrutha Gayathri in Bengaluru; Editing by JoyjeetDas)
