Overview
The ITA-ASIL-ICSID Conference is presented annually by the ITA Academic Council with the American Society of International Law (ASIL) and, from 2026, with The International Centre for Settlement of Investment Disputes (ICSID). The conference will occur immediately preceding the ASIL Annual Meeting. Scholarship is a hallmark of this conference.
The global investment treaty regime has undergone profound transformation in recent decades. Once hailed as a guarantor of investor confidence and global capital flows, investment treaties are now being renegotiated, recalibrated, or even set aside by states seeking greater policy space, alignment with sustainable development goals, and protection from arbitral proceedings. This conference takes stock of the forces reshaping investment treaty practice, the role of emerging jurisprudence and institutions, and the political economy behind treaty exit and re-design. Panels feature leading counsel, government negotiators, academics, and key personnel of international organizations to explore the present and future of the investment treaty system.

9:15-10:00 am - Keynote Discussion - The Negotiation of Investment Treaties
The reform process spearheaded by UNCITRAL Working Group III has become a global laboratory for conceptual and doctrinal shifts in investor-state dispute settlement (ISDS). UNCITRAL Working Group III has given states, particularly capital-importing states, an unprecedented forum for effecting changes in the investment treaty regime that go beyond the Working Group’s immediate work product. State representatives consider and debate policy positions on questions of regulatory space and arbitral liability under the treaties, and are brought up to speed on critical developments in the field, including the content of newer generation treaties that favor host states. Such exposure can change the dynamic of negotiations of particular treaties between states, even for bilateral treaty discussions that ordinarily occur in a somewhat siloed environment. This Keynote Discussion will consider the broader impact of Working Group III on investment treaty negotiations, including introducing host-state-friendly provisions in treaties under negotiation, the education and training of government representatives on treaty exposure, and efforts to conduct public consultations on states’ investment regimes.

10:00-10:15 am - Break
10:15-11:15 am - Panel: Recalibration of Investment Treaties
Even after mindful negotiation, investment treaties may fall short of their goals, or goals may change. Rather than terminating treaties, many states have opted for more creative recalibration. This may take the form of amending existing BITs, adopting interpretive statements, renegotiating key clauses, or acceding to new-generation bilateral or multilateral frameworks that rebalance obligations. Recalibration reflects both policy sophistication and political pragmatism - especially for states concerned with investor confidence, treaty shopping, and exposure to legacy claims. This panel will examine, inter alia, specific recalibration tools: rebalancing substantive standards (e.g., FET, expropriation), procedural reforms (e.g., ISDS opt-in/out provisions), and sunset clause renegotiation. Case studies will be drawn from Canada’s evolving treaty model, Colombia’s approach to balancing investor protection with environmental commitments, and ASEAN’s efforts to preserve coherence amid diverse national reforms.

11:15-11:30 am - Break
11:30 am-12:30 pm - Termination of Investment Treaties
Unexpectedly, more capital-outbound states have terminated their investment treaties than capital-inbound states in the last few years. Prominently in 2020, EU Member States agreed to terminate intra-EU BITs via a termination agreement pursuant to Achmea (ECJ). More recently and dramatically, many states including Spain, France, Italy, Germany, and the United Kingdom, have withdrawn from the Energy Charter Treaty (ECT), although they remain bound by its 20-year sunset clause, even as the remaining state parties have undertaken a radical amendment of the ECT. Looking to the ECT as a case study, this panel will consider the rationales offered by withdrawing states and impact on remaining states, as well as the resulting jurisdictional confusion over which investors are protected and to what extent.
