U.S. Supreme Court Will Not Hear CA Contract Case

LCG, June 3, 2002-California lost its appeal over seized electricity contracts on Monday.

California governor Gray Davis California seized Power Exchange (CalPX) forward contracts during the California electricity crisis. A San Francisco lower court ruled that Davis could not seize the contracts, and the U.S. Supreme Court denied his appeal without providing comment.

Governor Davis took control of contracts made during the crisis on behalf of electricity consumers who faced blackouts. Duke Energy Corporation sued Davis last year, saying that the contracts were seized illegally. The 9th U.S. Circuit Court of Appeals ruled 2-1 in favor of Duke in Davis v. Duke Energy Trading and Marketing.

The governor argued that the seizure was acceptable under California's sovereign immunity, whereas Duke Energy argued that it was a violation of the Constitution's Supremacy Clause.
