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. This was initially led by Yee Leong until his departure with a team for Allen & Gledhilll in 2013.

Andre Yeap SC has led the practice since then, supported by recently promoted deputy head Kelvin Poon. Several partners in the practice are former law clerks or colleagues of Menon, including construction and projects head Soh Lip San, Sim Chee Siong and Avinash Pradhan.

In addition to Yeap, the firm fields six senior counsel, including Francis Xavier, who sits as arbitrator.

Rajah & Tann reckons it still has the largest stand-alone arbitration practice of any firm in Singapore, with around 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, Hanoi and Da Nang. It also has affiliations with firms in Indonesia, the Philippines, Malaysia and Cambodia, as well as Al Tamimi & Company in the UAE.

Who uses it?

The firm advises 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 also has metals and mining clients such as Sumitomo, Bhushan Power & Steel, and Global Steel Philippines.

In the telecoms sector it has advised AT&T. Other well-known clients are Kempinski Hotels, Singapore Airlines and Air Asia.

Government clients include 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 been at the set-aside and enforcement stage. 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 Lao gaming conglomerate on the basis that the arbitrators wrongly chose Singapore and not Macao as the arbitral seat.

In 2012, Rajah & Tann secured 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. The award was partially upheld in the courts.

The firm helped a subsidiary of Indonesia’s Lippo group win a US$42 million SIAC award arising from a dispute over control of a Chinese hospital.

Recent events

Rajah & Tann is defending the Philippines against an ICC claim worth US$15 billion brought by Chevron and Shell over tax liabilities relating to an oil and gas concession.

It is also defending the Maldives against a US$130 million SIAC claim over a stalled joint venture to reclaim and develop islands and a lagoon. The SICC rejected a challenge to a jurisdictional award in favour of claimant Prime Capital in 2021.

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

Other clients include an Indian conglomerate in a US$21 billion SIAC arbitration over alleged breaches of non-disclosure agreements and a former official in a US$2.5 billion investment arbitration under the US–Vietnam trade agreement.

It also continues to represent Vedanta Resources in litigation filed by India relating to two investment treaty arbitrations worth a combined US$3 billion.

It is defending a Vietnamese state-owned company in a US$1 billion SIAC arbitration over a thermal power plant project. 

Other work has included an ad hoc arbitration against a South East Asian contractor, over the construction of an airport, and a SIAC arbitration under Cayman law between the partners of a private equity fund.

It has also been reported that the firm is defending a company that operates a special economic zone in Cambodia in a US$14 million arbitration brought by two subsidiaries of Singapore’s Asiatic Group relating to tariff revisions affecting a power plant.

The firm appointed Poon as deputy head of international arbitration, and Devathas Satianathan, Alessa Pang and Matthew Koh were promoted to the partnership.

Client comment

A client in an LCIA arbitration calls the firm’s “very competent” construction disputes team “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”.
