U.S. Chamber files amicus brief

August 25, 2006

NCLC filed an amicus brief urging the Supreme Court to reject lower standards for allowing antitrust lawsuits to proceed through the judicial process. In the case, the Second Circuit overturned a district court’s dismissal of a complaint filed against four major telecommunication providers. The complaint alleged that the companies’ failure to compete in each other’s markets constituted a conspiracy sufficient to establish an agreement to restrain trade. NCLC pointed out in its brief that businesses are often engaged in parallel activities, and without having an evidentiary requirement to prove a conspiracy, any business might find itself unfairly targeted for antitrust allegations.
