Implications for Investor-State Disputes Arising From the International Court of Justice’s Judgment in Certain Iranian Assets

April 26, 2023

The key takeaways from the Judgment are as follows:

  1. The performance of sovereign functions, such as the handling of foreign reserves abroad, as done by Bank Markazi, Iran’s Central Bank, can deprive an entity of protections otherwise afforded under the Treaty of Amity to companies performing commercial activities.
  2. The Court provided a broad reading of the fair and equitable treatment standard, rejecting the U.S. position that the applicable standard for FET was merely the minimum standard of treatment under customary international law because the Treaty of Amity, Economic Relations, and Consular Rights between the United States of America and Iran did not contain such express limitation.
  3. The Court noted the parties’ agreement that the FET standard includes protections against the denial of justice, but its assessment imposed a high threshold, failing to find a denial of justice where Iranian companies could appear before U.S. courts to make legal submissions, even where the U.S. enacted and U.S. courts applied legislative provisions that removed defenses based on the Iranian companies’ separate legal personality from Iran.
  4. The Court elucidated three elements for determining the “reasonableness” of a measure: (i) a legitimate purpose, (ii) a relation between means and ends, and (iii) minimal proportionality between purpose and effects, that is, the absence of manifest excessiveness.
  5. The Court held that the taking of assets through judicial measures, when combined with a specific element of illegality such as a denial of justice or an unlawful exercise of regulatory powers, can amount to unlawful takings or expropriation.
  6. Unless expressly stated otherwise, the standard of full protection and security affords protection from physical harm only and does not include legal protections.

On March 30, 2023, the International Court of Justice (ICJ or the Court) issued its judgment in the case concerning Certain Iranian Assets (Islamic Republic of Iran v. United States of America) (the Judgment).1

This case is significant as it marks the first time in over three decades that the ICJ has dealt with norms of international investment law in extensive detail. The last time the Court did so was in 1989 in the Elettronica Sicula S.p.A. (ELSI) (United States of America v. Italy) case,2 where the ICJ rejected the United States’ claims that Italy had breached the 1948 Treaty of Friendship, Commerce and Navigation between the two countries. The Judgment also has significant implications for host states and foreign investors when defending against or bringing investor-state claims resulting from the imposition of sanctions. The Judgment is bound to be cited extensively by parties in subsequent investor-state cases, particularly given that it touches on several contested standards of investment protections and carries highly persuasive value as a judgment rendered by the principal judicial organ of the United Nations.

Among other things, the Court dealt with key investment protection standards such as the fair and equitable treatment (FET) standard; the standard of “reasonableness” within the framework of protection from unreasonable and discriminatory measures; expropriation through judicial measures; the failure to exhaust remedies; the “unclean hands” defense; and the concept of full or constant protection and security.

Signaling the important but contested nature of the standards addressed in this case, 13 of the 15 sitting judges and judges ad hoc weighed in with separate opinions pursuant to Article 57 of the Court’s statute, setting out points of departure from the findings in the majority decision.
