Guidance on Enhancing Cross-Border Leniency Cooperation

This guidance is intended to provide practical advice for competition agencies to assist them in engaging with other jurisdictions on matters involving multijurisdictional leniency applicants, with the two parallel aims of first, making international enforcement efforts more effective and second, helping to reduce disincentives for prospective leniency applicants.

This guidance expands on the practices and principles of international cooperation in cartel enforcement contained in other ICN work products. These include the “Good Practices for Incentivising Leniency Applications” report (2019), the “Checklist for Efficient and Effective Leniency Programmes” (2017), and Chapters 2 and 9 of the Anti-Cartel Enforcement Manual, “Drafting and Implementing an Effective
Leniency Policy” (2014) and “International Cooperation and Information Sharing (2013).”
