On January 7, the Commodity Futures Trading Commission filed with the U.S. Court of Appeals for the District of Columbia Circuit a motion for leave to intervene in an action filed by Amaranth Advisors, L.L.C. and others against the Federal Energy Regulatory Commission (FERC), in which Amaranth challenges FERC’s authority to initiate a proceeding alleging manipulation in the trading of natural gas futures contracts. The CFTC seeks to intervene for the purpose of addressing the scope of the CFTC’s exclusive jurisdiction with respect to the trading of futures on registered futures exchanges.
