The mandate of the Cartel Working Group is to address the challenges of anti-cartel enforcement, including the prevention, detection, investigation and punishment of cartel conduct cross the range of ICN members with differing levels of experience and resources. At the heart of antitrust enforcement is the battle against hard core cartels directed at price fixing, bid rigging, market allocation and output restriction.

The Cartel Working Group is co-chaired by the Netherlands Authority for Consumers and Markets, the South African Competition Commission, and the Colombian Superintendencia de Industria y Comercio.

The Cartel Working Group consists of two subgroups:

Subgroup 1: Legal Framework (SG1) addresses the legal and conceptual challenges of anti-cartel enforcement.  The focus of the subgroup is examining policy-level issues of the institutional and investigative framework for the detection and punishment of hard core cartels.


Subgroup 2: Enforcement Techniques (SG2) aims to improve the effectiveness of anti-cartel enforcement by identifying and sharing specific investigative techniques and advancing the education and information sharing agenda of the Cartel Working Group.
