The mandate of the Cartel Working Group (CWG) is to address the challenges of anti-cartel enforcement, including the prevention, detection, investigation and punishment of cartel conduct. At the heart of antitrust enforcement is the battle against hard core cartels directed at price fixing, bid rigging, market allocation and output restriction.
