About the Section

The Antitrust Section provides an international forum for thought leadership with respect to antitrust law developments and the profession through submissions to competition agencies, training programs/missions, developing the law through our conferences, publications, and interaction with antitrust enforcement authorities and the profession.

In addition, there is a strong commitment to bring together international practitioners to facilitate closer working relationships. The Section is increasingly relied upon by government officials and members of the private sector for its expertise and practical input into antitrust developments, including through its Working Group submissions.

Working Groups and policy submissions

The Antitrust Section has formed a number of working groups to study major international competition policy issues and to submit comments to regulators on proposed new and reformed legislation.

The IBA Unilateral Conduct and Behavioural Issues Working Group has 15 members representing a large number of jurisdictions covering Europe, Asia, Australia, Africa and the Americas. The Group is responsible for monitoring and commenting on a range of competition issues that arise, inter alia, from unilateral conduct and abuse of dominance or misuse of market power as well as cooperative/horizontal (non-cartel) and vertical agreements.

It aims to encourage best practice in the ongoing development of international laws in these areas by commenting on consultations on proposed new and reformed legislation. This includes reviewing and commenting on proposed new legislation and legislative changes; engaging in discussions about the nature of conduct that should be proscribed by competition law; reviewing and commenting on regulatory responses to anti-competitive conduct including investigations and prosecutions; and commenting on guidelines associated with compliance initiatives designed to raise awareness of competition issues in relation to unilateral conduct, cooperative agreements and vertical agreements.

The reactions of competition authorities to the Covid-19 pandemic

The pandemic caused by Covid-19 has also affected the antitrust universe. In a way never imagined, in a very short period of time, the authorities have had to adapt themselves to a new world in which lawyers, economists and companies work from home, face-to-face meetings are not possible and resources are limited.

Information Exchange and Related Risks: A Jurisdictional Guide

Published in September 2022 by Concurrences

ISBN: 9781954750029

The prohibition on exchanging commercially sensitive information among competitors is one of the most fundamental antitrust rules. Companies and individuals may face potential exposure for anticompetitive information exchange, not only in their day-to-day business due to the applicable conduct and behavioral rules, but also in the context of M&A deals due to applicable gun jumping regulations. The Cartels Working Group of the Antitrust Section of the International Bar Association has formulated a comparative guide across 28 jurisdictions, encompassing all global regions, to provide a compendium of best practices and key insights about leading cases, laws and regulations, as well as enforcement trends. Contributed by distinguished practitioners, each chapter provides an overview of the national competition rules and principles that guide information sharing in that jurisdiction, followed by the types of information sharing that may be caught, the enforcement policies and practices of the competition authority and applicable sanctions for parties that are found guilty of an illegal exchange of information. The book also provides a high level overview by the editors outlining trends observed across jurisdictions, to provide insight to the international business community, their advisors as well as to competition authorities.

The jurisdictions covered include Argentina, Australia, Brazil, Canada, Chile, China, Colombia, European Union, Finland, France, Germany, India, Israel, Italy, Japan, Mexico, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, The Netherlands, Turkey, Ukraine, United Kingdom, and the United States.
