WASHINGTON (AP) -- The Supreme Court ruled Monday that Halliburton Co. shareholders can pursue a class-action lawsuit claiming the oil services company inflated its stock price.
The high court overturned a lower court ruling against the shareholders, who want to represent all investors who bought Halliburton stock between June 1999 and December 2001.
The lawsuit argues that Halliburton deliberately understated the company's liability in asbestos litigation, inflated how much money its construction and engineering units would bring in and overstated the benefits of a merger with Dresser Industries. When Halliburton made corrective disclosures, it made the stock price drop and caused investors to lose money, the lawsuit said.
The 5th U.S. Circuit Court of Appeals in New Orleans refused to let the lawsuit go forward as a class-action, saying to get class-action certification, the shareholders needed to prove "loss causation, i.e., that the corrected truth of the former falsehoods actually caused the stock price to fall and resulted in the losses."
But the Supreme Court said that ruling was incorrect.
"The Court of Appeals erred by requiring EPJ Fund to show loss causation as a condition of obtaining class certification," Chief Justice John Roberts wrote in the court's unanimous opinion.
The case now goes back to the lower court.
The case is Erica P. John Fund Inc., v. Halliburton Co., 09-1403.
