In this capacity, he attended meetings of the Global Forum on Tax Transparency in Paris and Mexico on behalf of the Cayman Islands Government. 

In addition to his work with the Ministry of Finance and CIMA, Mr. Sibblies also served as a member and Chairman of the Cayman Islands Law Reform Commission (2004 – 2010) and is currently a member of the Cayman Islands Judicial and Legal Services Commission.
