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.

Irish Supreme Court confirms witnesses must speak up about cartels or risk prosecution

Canada: competition update

Peter Flynn and Victoria Turner report on a few significant developments in Canadian competition law, including: the Competition Tribunal’s decision in the Vancouver Airport Authority case; a public call-out for information by the Bureau regarding anti-competitive conduct in the digital economy; and significant policy developments and international cooperation at the Bureau.

China: new framework for resale price maintenance analysis

In the last week of June 2019, a copy of a ground-breaking court ruling emerged on social media in China: the order by the Supreme People's Court in the case between Yutai Technology Feed and the Hainan Price Bureau. The order provides a direct answer to the question of whether or not the Chinese antitrust authorities bear the burden of proving the anti-competitive effects of companies' resale price maintenance conduct. China's highest court found that they do not.

The reactions of competition authorities to the Covid-19 pandemic
