On April 29th, the Court of Appeals for the D.C. Circuit canceled oral arguments scheduled in the National Association of Manufacturer’s (NAM) challenge to the conflict minerals rule. Following the court’s dismissal of the American Petroleum Institute’s case challenging the resource extraction rule, NAM filed a motion on April 30th to transfer its conflict minerals case to district court. The case will be heard first by a trial judge, and then the decision of the district court could be appealed to the court of appeals. Many had hoped for a decision on the legal challenge by the fall, but the decision in American Petroleum Institute and the resulting transfer of NAM v SEC to the district court will undoubtedly delay the resolution of this challenge by many months.
