Founded in 1976, Rajah & Tann is one of Singapore’s leading full-service firms. The roots of the international arbitration practice go back to 1999, when Sundaresh Menon (later Singapore’s attorney general and now chief justice) and Chong Yee Leong worked on a case in Bangkok. Other cases swiftly followed and the pair worked on cases throughout Asia over the next four years.

The entire group moved laterally to Jones Day in 2003, but returned three years later with new international know-how and experience. At this point Rajah & Tann created a stand-alone arbitration practice, initially led by Yee Leong until he left with a team for Allen & Gledhill in 2013.

Following that, Andre Yeap SC led Rajah & Tann’s practice for the best part of a decade before being succeeded in 2022 by his deputy Kelvin Poon (now also SC). The team includes construction and projects head Soh Lip San, Sim Chee Siong and Avinash Pradhan, the new deputy head of the arbitration practice.

In addition to Yeap, the firm fields seven SCs, including Francis Xavier, who sits as arbitrator. Other names to know include Eri Hertiawan and newly minted partner Simon Barrie Sasmoyo, who jointly lead the firm’s team in Indonesia.

Rajah & Tann reckons it still has the largest stand-alone arbitration practice of any firm in Singapore, with approaching 20 partners working in the area. It claims to have handled over 600 arbitration matters in Asia and elsewhere since 2013. The firm says that not only is it the heaviest user of SIAC, but also it has been involved in almost half the cases brought before the Singapore International Commercial Court (SICC).

It regards its main competitors for high-end and complex arbitration work not as other Singapore firms but rather as international firms in the UK and the US.


Apart from Singapore, the firm has offices in Bangkok, Jakarta, Shanghai, Vientiane and Yangon.

A 2014 tie-up with a Vietnamese firm gave it offices in Ho Chi Minh City and Hanoi. It also has affiliations with firms in Indonesia, the Philippines, Malaysia and Cambodia.

Who uses it?

The firm has advised clients in the energy, chemical and construction and engineering sectors, such as Malakoff, the largest independent power producer in Malaysia; PETRONAS Chemicals Group; Korea’s GS Engineering and Construction and Samsung C&T; Australia’s Thiess; and China Machine New Energy Corporation.

It has also had metals and mining clients such as Sumitomo, Bhushan Power & Steel and Global Steel Philippines; and telecoms company AT&T. Other well-known clients are Kempinski Hotels, Singapore Airlines and AirAsia.

Government users have included Laos, Lesotho, Indonesia, the Philippines, Kazakhstan, the Maldives and Mauritius’s State Trading Corporation. It has also been appointed as legal adviser to the Chinese embassy in Singapore, advising on matters relating to the embassy itself as well as Chinese citizens and companies.

Track record

Some of the firm’s most visible successes have come in the Singaporean courts. It secured the first ever set-aside of an investment treaty award on the merits in Singapore, on behalf of its client Lesotho, in 2017. It also overturned the enforcement of a US$200 million SIAC award against a Laos gaming conglomerate on the basis that the arbitrators wrongly chose Singapore and not Macao as the arbitral seat.

In 2012, Rajah & Tann landed a US$100 million SIAC award against the Philippine National Bank and several other financial institutions, on behalf of companies owned by Indian steel magnate Pramod Mittal. A big chunk of the award was later set aside, however.

A subsidiary Indonesia’s Lippo Group relied on the firm when it won a US$42 million SIAC award arising from a dispute over control of a Chinese hospital.

The firm helped Norwegian oil services company NOV Norway enforce an award against a local conglomerate in Singapore, even though the court found that it was issued in the name of a company that no longer exists.

Recent events

Rajah & Tann continues to act for a conglomerate in a US$21 billion SIAC arbitration over alleged breaches of non-disclosure agreements.

The firm acted for a former government official in relation to a US$2.5 billion investment arbitration under the US-Vietnam trade agreement.

It is defending a Vietnamese state-owned company in an over US$3 billion SIAC arbitration over a thermal power plant project. 

Bahamian oil company Perenco used the firm as it sought enforcement of its US$412 million ICSID award against Ecuador in Singapore.

It is acting for Germany-based COALORBIS in a US$12 million credit dispute with a Hong Kong trading company concerning the sale of Indonesian steam coal to China. It is working on a SIAC case concerning a supply contract for a Pakistani power plant, and another case at the centre between the partners of a private equity fund.

Poon was one of only two Senior Counsel appointments in Singapore at the start of 2023.

The firm brought in partner Vanina Sucharitkul, a Thai-French-US national who heads the Thailand branch of the Chartered Institute of Arbitrators. Sucharitkul, who previously spent a decade at Herbert Smith Freehills, is initially working from Bangkok with a view to relocating to Singapore.

The firm promoted Sasmoyo and Daryl Sim to partner. Divyesh Menon joined as counsel from Mayer Brown. Partner Alessa Pang left for WongPartnership.

Client comment

A client who was assisted by Yeap in an ICC case in Singapore praises his “vast experience”, adding that his insight and approach gave them “comfort and assurance”.

A user in an LCIA case says the firm’s construction disputes team is “diligent and good value for money”. They single out the “very good strategic thinker” Ng Kim Beng and also Pradhan, who “knows construction and construction law inside out”.

Another client says the firm is “proactive, solution-focused, diligent, and did an outstanding job preparing 10 inexperienced witnesses for the arbitration hearing”. They also praise the “very experienced and clear” Pradhan, as well as Tan Chuan Thye, who “provided outstanding advice and prepared witnesses very well”.
