Douglas represents and advises companies and individuals on a wide range of commercial law issues. He represents U.S., European and Japanese companies with operations and subsidiaries in Thailand. He has substantial experience advising multinational corporations on mergers and acquisitions in Thailand, including representation of:

  • IBM in the sale of its PC business in Thailand to Lenovo.
  • Bain Capital in its acquisition of a majority stake in a Thai public company.
  • Japanese companies such as ITOCHU and Matsushita (Panasonic) in local transactions and debt restructuring matters, including, among others, ITOCHU’s recent acquisition of Dole’s operations in Asia (acquisition of Dole’s businesses in Thailand).

Douglas also has more than 30 years experience supervising and handling litigation and arbitration matters. He has taken cases to trial in the U.S., and he has handled major arbitration matters in the U.S. and Asia. This experience not only makes Douglas a strong and effective advocate when disputes arise, but also adds depth to his transactional practice. Douglas has a recognized strong anti-corruption practice that includes substantial experience with the U.S. Foreign Corrupt Practices Act (FCPA).  He has authored articles and spoken on anti-corruption issues in Thailand and abroad (e.g., Singapore, Japan, Washington, D.C. etc.).  Mr. Mancill has locally supervised scores of internal compliance investigations and routinely advises clients on matters relating to the FCPA.

His practice also emphasizes debt and corporate restructuring matters. Douglas has handled several high profile restructuring matters in Thailand before joining PriceSanond after the 1997 financial crisis.

Douglas holds leadership positions in committees and task forces of the American Chamber of Commerce in Thailand (AMCHAM) and the American Bar Association (ABA). He has spoken at numerous events organized by, among others, the ABA, the International Chamber of Commerce (ICC), LawAsia, the British Chamber of Commerce in Thailand (BCCT), the American Chamber of Commerce in Singapore, AMCHAM, CAL-Asia, the Japanese Institute of International Business Law and the Japanese Ministry of Justice. He has also published articles on U.S. and Thai law.  Most recently, Douglas wrote the Thai chapter to the ABA’s International Joint Ventures: A Guide to U.S. Lawyers.

Before joining PriceSanond in 1998, Douglas was partner from 1992 until 1998 in the US law firm of Graham & James (now Squire Patton Boggs), which was then affiliated with PriceSanond. He was an associate at Graham & James from 1986 until 1991. Before joining Graham & James, Douglas worked in the legal department of Bank of America and Sheppard, Mullin, Richter & Hampton’s Banking and Finance Department.



Douglas’s corporate and M&A experience includes, among other matters, representing a major oil company in its acquisition of a local company that had approximately 50 branches throughout Thailand, representing a major private equity firm in its acquisition of two American Standard companies, representing IBM in its local acquisition of an IT Consulting group within PWC and in its sale of its local PC business to Lenovo, representing Avery-Dennison in its acquisition of the local subsidiary of Paxar, supervising the due diligence of a major Thai bank following the 1997 financial crisis. Douglas also provides general corporate and employment advice to many other foreign companies doing business in Thailand.

Douglas is recognized in Thailand for his work on FCPA and fraud investigations. Before his secondment to Thailand in 1998, Douglas worked on an internal investigation by an airplane parts manufacturer into alleged corrupt foreign dealings in Asia, a major embezzlement case, several cases involving alleged self-dealing and several creditor fraud cases. In Thailand, Douglas routinely works on internal FCPA reviews and fraud investigations and claims. He has handled internal fraud investigations and compliance reviews for, among others, an auto parts maker, a major “household name” company in the IT sector, several major companies in the oil industry, the entertainment sector and several medical equipment suppliers.

Dispute Resolution:
Douglas has an active dispute resolution practice. He handled major several trans-national litigation matters while in the U.S. before his secondment to Thailand, including federal court litigation on behalf of Japanese, Chinese, Indonesian, Taiwanese, Singaporean and Thai parties. While handling such litigation, Douglas conducted discovery in multiple Asian jurisdictions and took or defended scores of depositions in Asia. While in the U.S., he handled and worked on several commercial cases through trial, including a distributorship dispute, an option agreement dispute, a bankruptcy adversary case involving complex IP issues and a seven week jury trial on behalf of Bank of America. He worked on an ICSID arbitration matter involving the alleged expropriation of a gem field in Sri Lanka. He has also worked on several Thai Arbitration Institute arbitration matters and ICC arbitrations. His experience handling dispute resolution matters in Asia is broad, and includes handling a dispute over a multimillion dollar claim from a damaged power plant, a dispute over interpretation of a power purchase agreement, a dispute over purported delays in the fabrication of an offshore oil rig, the application of Thai maritime law in foreign court proceedings, the application of Thai law in a foreign probate proceedings and a construction dispute involving the Yadana pipeline between Thailand and Myanmar.

In the area of insolvency and debt restructuring, Douglas handled numerous U.S. bankruptcy matters before his secondment to Thailand in 1998. In Thailand, he has worked on matters involving:

  • a Japanese manufacturing company in a contested bankruptcy reorganization filing involving a local manufacturer of consumer electronic products,
  • a major Japanese trading firm in its efforts to recover over US$100,000,000 from a major Thai steel mill,
  • the Singapore branch of an Australian bank in contested CDRAC proceedings and ensuring IPIT litigation,
