The U.S. Commodity Futures Trading Commission will appeal ajudge's ruling that rejected efforts to curb speculativederivatives trading after the 2008 financial crisis.

The commission filed a notice of appeal today in federal courtin Washington, seeking to ask a three-judge panel to reverse aruling by U.S. District Judge Robert Wilkins that said the CFTCfailed to assess whether limiting the number of contracts a tradercan have in oil, natural gas or other commodities was necessary andappropriate.

“The rule addresses Congress's concern that that no singletrader be permitted to obtain too large a share of the market, andthat derivatives markets remain fair and competitive,” CFTCChairman Gary Gensler said in a statement today. “I believe it iscritically important that these position limits be established asCongress required.”
