The US Supreme Court has decided not to review a ruling that agribusiness giants Archer Daniels Midland and Cargill can be sued for allegedly conspiring to fix the price of high fructose corn syrup. The court rejected appeals by ADM, Cargill and AE Staley Manufacturing, a unit of UK-based Tate & Lyle, that a 1995 class-action lawsuit should have been dismissed because it presented only "ambiguous" evidence of a conspiracy, reported Reuters.
