Parallel Proceedings at the Intersection of FDI Screening and Investment Arbitration

Authors: Sally Pei (Arnold & Porter) and Joel Dahlquist (Arnold & Porter)    Introduction  States in Europe and beyond are increasingly screening incoming foreign direct investment (“FDI”). When a host State blocks or restricts an investment on security grounds, the affected investor may seek judicial review domestically, initiate investor-state dispute settlement (“ISDS”) proceedings under an applicable investment treaty, or pursue both in ...

Navigating Treaty Liability for Conditional Approvals in Foreign Investment Screening

Author: Dean Merriman (Barrister at the Victorian Bar)    I. Imposition of Conditions on Foreign Investment: Anecdotes from Australia  It is well known that domestic investment screening authorities frequently are given the power to approve inbound foreign investments subject to the imposition of certain conditions, including on national security grounds.

Investment Screening Between Discretion and Arbitrariness – Charting the Borderlands

Authors: Steffen Hindelang (CELIS Institute; Uppsala University), Helene Schramm (CELIS Institute) and Liam McGrath (CELIS Institute) Introduction  Foreign investment screening regimes are built on discretion. Screening decisions often turn on assessments of open-ended lists of risks to ‘national security’ – an inherently ambiguous concept (J Benton Heath 2022, p. 295), which is constantly evolving as States adjust to new threats and vulnerabilities (OECD, 2022, p. 16). The resulting broad margin of appreciation for screening ...

Disclosure and Confidentiality in Investment Screening

Author: Dorieke Overduin (Sovereign Arbitration Advisors)    Introduction  In order to assess risks posed by foreign direct investments to national security, authorities must understand not only the target business, but also the investor, its ownership structure, sources of financing, governance arrangements, and potential foreign state involvement. As a result, investment screening procedures impose extensive and often highly detailed disclosure obligations. This places investors ...

Legal Standards, Evidentiary Threshold, Transparency and Due Process in the Context of Investment Screening and Investment Disputes

Author: Jonas Hallberg I. Legal Standards and Evidentiary Threshold Security assessments of a prospective investment necessarily involve an assessment of future contingencies; the evidentiary threshold cannot therefore be set unduly high.  The deciding body must collect classified and secret information from its security agencies. Normally this is done in the form of opinions.   Whatever evidentiary threshold is set, the security ...

Fair and Equitable Investment Screening

Author: Dr. Bálint Kovács (University of Szeged)    Introduction  With the widespread adoption of investment screening by Western states, there is increasing evidence as to the ways in which this tool of economic security is implemented. Investment screening accommodates an important exception to open market principles: the national security imperative. The liberalisation of foreign direct investment (“FDI”) flows is now limited ...

Author: Alexandros Bakos ((Postdoctoral researcher, Hamad Bin Khalifa University, College of Law) Introduction After the Achmea and Komstroy sagas, marking the end of intra-European Union (EU) investor-state arbitration, the Union finds itself again at the centre of some investment arbitration drama. Sanctioned Russian investors are increasingly bringing arbitral claims against the EU and its Member States in the hope that ...

Between Deadlines and Discretion: Timely Decision-Making in Investment Screening

Authors: Xueji Su (University of Macau) and Alessandro Zocchia (University of Macau)    Introduction: The Pocket Veto Phenomenon  Investment screening involves a procedurally layered process involving notification, jurisdictional assessment, inter-agency consultation, risk analysis, possible mitigation negotiations, and final clearance or prohibition. In this setting, time is not a neutral variable. Delay can operate with the same practical force as a formal prohibition: it may cause contractual long-stop ...
