Professional notice



Our Competition & Antitrust Practice, co-headed by Daren Shiau, BBM, PBM, and Elsa Chen, is the largest and most experienced dedicated practice in Singapore and South-east Asia. Uniquely, our unparalleled practice is made up of lawyers and economists dedicated to antitrust law full-time, who have the expertise, experience, and bandwidth to handle the most complex of antitrust cases for clients. The in-house competition economics team is also the only one of its scale in the region, and amongst the few law firms globally with such capabilities.

We frequently assist clients in cross-border merger assessments, gun-jumping and technical filings, and have unsurpassed experience in complex cartel and monopoly investigations. We are also regularly commissioned by governments to draft competition legislation, codes and policies, including in the aviation, energy, media, postal, telecommunications sectors and are trainers for the ASEAN Experts Group on Competition.

Our Practice is the top Singapore merger control adviser on deal flows with total combined values exceeding US$700 billion, including the acquisition of Refinitiv Holdings Limited by London Stock Exchange Group, the proposed merger between Analog Devices, Inc. and Maxim Integrated Products, Inc and every other of the 12 mergers publicly reviewed in 2021.

To-date, we have acted on three out of every for four mergers publicly reviewed by the Competition and Consumer Commission of Singapore (“CCCS”) to-date in Singapore, including the majority of Phase 2 reviews by the CCS, and negotiating and clearing second requests.

We are also the first and only firm to have successfully overturned a provisional infringement decision by the CCCS, in both antitrust and merger control. Our team also secured the first merger notification cleared by the CCCS based on the “failing firm defence” as well as secured the first conditional clearance by the CCCS subject to local commitments.

In addition, our Firm defended clients in 100% of all the CCCS’ international cartel decisions to-date, including acting for the successful amnesty applicant of Singapore’s first global cartel decision (freight forwarding), and the successful leniency applicants of the second (ball bearings) and third (aluminium electrolyte capacitors) decisions. We have also been involved in landmark abuse of dominance and unilateral effects cases.

Notably, we recently represented the largest appellant in a watershed Competition Appeal Board matter where the CCCS was adjudged to have failed to establish liability in an issued Infringement Decision.

The strength of the Practice is augmented by our Partner, Scott Clements, who is a Singapore-qualified competition law specialist with over 16 years of experience in Singapore, and Senior Adviser, Mr Lam Chuan Leong, who has held key positions across a broad range of government agencies. Most notably, he was the first Chairman of CCCS, a position he held for a decade, since its inception in 2005.
