In Champagne Metals v. Ken-Mac Metals, Judge Joe Heaton, US District Court for the Western District of Oklahoma, has found that the plaintiffs have presented sufficient evidence of a conspiracy among aluminum suppliers and mills to justify use of the co-conspiratory hearsay exception. The case alleges that the nations largest aluminum distributors conspired to pressure mills not to deal with the price cutting Champagne. The court rested its holding on a strong economic theory of conspiracy and some direct evidence as well as circumstantial evidence. The case will not proceed to trial.
