Charis specialises in international commercial and investment treaty arbitration and public international law.
She is admitted in three jurisdictions (Singapore, England & Wales and New York), and she advises States, State-owned companies and leading companies in a wide range of complex disputes and public international law issues, including in high profile State-to-State disputes before the International Court of Justice (ICJ). She has also been appointed as a World Trade Organisation (WTO) Panellist hearing a trade dispute between the European Union and the United States.
Charis’ experience includes investment and commercial arbitrations under the rules of major arbitration institutions, including ICSID, ICC, SIAC and SCC, as well as ad hoc proceedings under UNCITRAL Rules. Charis is appointed as Counsel and she also sits as an Arbitrator.
She advises National Oil Companies (NOCs) and International Oil Companies (IOCs) in both contentious and non-contentious upstream oil and gas matters. A unique area of her specialisation is where the practice of oil and gas crosses into the public international law sphere, such as where oil blocks straddle disputed boundaries.
Charis has been recommended by Who’s Who Legal, Asia Pacific Legal 500 and GAR. An initiative she spearheaded for the training of Government officials was also awarded the Asia Pacific FT Innovative Lawyers award.
She is currently a member of the Core Committee of the ICC’s Singapore Arbitration Group, on the editorial board for the ICC Dispute Resolution Bulletin, and on the Council of the International Law Association (ILA) Singapore branch.
