State parties’ “mutual actions” over a treaty – including interventions such as interpretation, modification and termination – have flourished in recent investment treaty practice. This trend brings to the fore the question of whether there are any limits to such actions, particularly due to the involvement of non-State entities, such as investors and arbitral tribunals….

The year 2021 has been the busiest year for Ukraine since 2008, with four investment arbitrations initiated against Ukraine. The odds were not always in Ukraine’s favour. Having secured the dismissal of the case for lack of jurisdiction in Littop and others v. Ukraine, Ukraine was defeated by the investor in Olympic Entertainment v. Ukraine….

In early 2021, we wrote a post on this blog welcoming the inclusion of specific provisions on third-party funding (TPF) in the 2021 ICC Arbitration Rules. Recent regulatory developments in TPF in investor-State dispute settlement (ISDS), including publication of the VIAC Rules of Investment Arbitration and Mediation (VIAC Investment Arbitration Rules), have enticed us to…

On January 20, 2022, ICSID submitted its amended rules to the Administrative Council for a vote, marking the end of the five-year-old process of modernizing the ICSID Rules.

In its judgment rendered today, the Court of Justice has quashed the General Court’s decision having ruled that the European Commission was not competent ratione temporis to assess whether the compensation paid by Romania to the Micula brothers, in implementation of a 2013 ICSID award rendered under the 2002 Sweden-Romania BIT, was constitutive of state…

In 2011, in an article titled ‘W(h)ither Fragmentation? On the Literature and Sociology of International Investment Law’, Professor Stephan Schill reflected on the prior decade of scholarly and practical developments in international investment law (IIL). He referred to the boom in specialised scholarship and the more than 400 investor-State disputes then in existence as reasons…

Globalization has diversified the actors, institutions, norms, and instruments on the international legal stage. With diversification comes increased specialization and, in turn, organization around so-called regimes. The notion that international legal regimes can exist autonomously has long been refuted; indeed, each regime draws from general international law to some degree. If regimes are not autonomous,…

Nearly 30 years have passed since world leaders signed the UN Framework Convention on Climate Change (“UNFCCC”), agreeing to combat “dangerous human interference with the climate system.” For many of those years, nobody seemed to take that commitment very seriously. But things look different now: climate law has hit its stride. At COP26 in November…

This post deals with the conceptual underpinnings and theoretical justification for the practice of counterclaims in investment arbitration. First, it is important to delineate this post from an analysis of counterclaims case-law in investment arbitration, as ample accounts of the counterclaim debate in practice can be found here, here, and here.  Equally, this post does…

Debates about the fragmentation of international law and the sometimes conflicting relationship between a state’s and investor’s obligations under international investment law (“IIL”), on the one hand, and public international law and domestic law, on the other, have gained renewed relevance for investment arbitration. Issues related to the interactions between these regimes have featured in…

Bilateral investment treaties depend upon international arbitration as the mechanism to resolve disputes between sovereign states and investors. Although offering obvious advantages over litigation before national courts, investors are not immune from the risk of proceedings becoming destabilized by external factors. A recent example involved Air Canada, the country’s flag carrier, and the Bolivarian Republic…

Inconsistent decisions have long been a major criticism in investment arbitration. This does not only pertain to decisions on procedure, jurisdiction or merits but also to quantum issues. This contribution will center around one unlikely connection that has the potential to enhance consistency and predictability in an area of quantification of damages in investment arbitration:…

On November 23, 2021, Ecuador’s Attorney General (“AG”), Iñigo Salvador Crespo announced the creation of a new institutional framework for handling disputes brought against the state and state entities with the vision of preventing and reducing litigation, particularly costly international arbitrations.

In 2021, we witnessed a number of interesting developments in the field of investment arbitration in Latin America. From Mexico’s actions potentially triggering numerous treaty claims, to Colombia’s four consecutive victories, to Ecuador’s return to the International Centre for Settlement of Investment Disputes (ICSID) Convention. Our authors did a tremendous job covering and sharing their…

Earlier this week, the YSIAC Conference 2021 took place virtually for the first time since its inception. The opening webinar was a panel discussion titled “Resolving ESG Disputes Through International Arbitration”, which agenda was to analyse the disputes in the buzzing environmental, social and governance (“ESG”) domain, distil the trends and lessons learnt therefrom, and…

The discussion within UNCITRAL Working Group III (WG III) on counterclaims has still remained, to a certain extent, deadlocked, as opposed to discussions on other topics under the table. As a result, the UNCITRAL Secretariat has been put (at least) until now in the unfortunate position of being unable to bring a coherent package of…

Investor-state disputes often involve an interplay of different bodies of international law.  In addition to investment law, disputes may invoke issues involving public international law, international human rights law, and international environmental law – and tribunals are faced with the challenges of trying to reconcile the sometimes conflicting rights created under these different bodies of…

Earlier this year, Colombia prevailed in two arbitrations under the Colombia-US Trade Promotion Agreement (“TPA”). The claims were filed by Alberto Carrizosa Gelzis, Felipe Carrizosa Gelzis and Enrique Carrizosa Gelzis (“Carrizosa brothers”) under the UNCITRAL Arbitration Rules, and by Astrida Benita Carrizosa (“Ms. Carrizosa”) under the ICSID Convention. In both arbitrations Ms. Carrizosa and the…

Western European countries have taken divergent approaches to dealing with the consequences of shutting down power plants while transitioning towards cleaner energy sources. On one side, Germany resolved the resulting compensation disputes by making settlement payments to the owners of affected nuclear and coal power plants. In contrast, the Netherlands appears reluctant to similarly compensate…

In May 2021, India’s National Company Law Tribunal (‘NCLT’) ordered the liquidation of Devas Multimedia (‘Devas’), on grounds of it having been incorporated for fraudulent purposes.

The Achmea saga has taken yet another twist. In a recent communication to the Dutch Parliament, the Dutch Ministry of Economic Affairs and Climate disclosed that it initiated “anti-arbitration” proceedings before the German courts on 11 May 2021 to “avert” two ECT-based ICSID arbitrations brought against it by the German energy companies RWE and Uniper (“Communication”)….
