Dr. Weiler was actively involved in the co-founding of institutions such as Oxford University Press’ Investmentclaims.com, the Society of International Economic Law, and the Annual Conference on International Investment Law and Arbitration, hosted in Washington DC by Juris Conferences since 2006.

His work was also instrumental in securing arbitral awards that contributed to the development of fundamental doctrines of international investment law such as International Thunderbird Gaming v. Mexico (legitimate expectations), S.D. Myers v. Canada (national treatment), and Pope & Talbot v. Canada (indirect expropriation, fair and equitable treatment, and abuse of authority).
