The Doctrine of Veil Piercing in Investment Law

I. Definition


The piercing or lifting of the corporate veil refers to a legal decision by a competent forum to disregard the limited liability of a corporation, treating its rights or duties as rights or duties of its shareholders.1 This concept is derived from common law2 and is evoked in cases where corporate personality is used as “a cloak for fraud or improper conduct”.3


Other closely connected notions include the nationality of the corporate investor, abuse of process,4 genuine and effective link, effective nationality5 and bad faith in investment treaty arbitration.

II. Veil piercing in public international law


According to the Barcelona Traction case, the place of incorporation determines the nationality of the legal entity regardless of the nationality of its shareholders.6 The dispute in this ICJ case arose out of Spanish governmental policy, which brought about the bankruptcy of the Canadian-registered Barcelona Traction company. Belgium espoused this claim, based on the Belgian nationality of Barcelona Traction’s shareholders. Spain objected to the Court’s jurisdiction on the basis that Belgium lacked standing under international law as the company was registered in Canada. The Court found that only the country of the place of incorporation could espouse a company’s claims under international law.7 Yet, the Court acknowledged that the company’s corporate veil may be lifted in exceptional circumstances, following the example of national law: “to prevent the misuse of the privileges of legal personality, as in certain cases of fraud or malfeasance, to protect third persons such as a creditor or purchaser, or to prevent the evasion of legal requirements or of obligations."8


The ILC’s commentary on States’ responsibility for internationally wrongful acts also recognizes the autonomy of juridical entities, while limiting it to cases where the corporate veil is device for “fraud or evasion”.9

III. Burden and standard of proof in investor-State disputes

A. Standard of proof


The threshold for applying this theory is very high, and tribunals have shown reluctance to declining jurisdiction based on veil piercing alone,10 notably when the BIT’s clause on nationality does not warrant its application,11 or when this doctrine is used for the purpose of obtaining security for costs from the claimant’s shareholders.12 

B. Burden of proof


In the Libananco case, the claim was brought by a Cypriot company against the Republic of Turkey, based on the alleged expropriation of the electricity companies ÇEAŞ and Kepez (ultimately belonging to the Uzan family). The Respondent raised the jurisdictional objection inter alia alleging that the investor “is the alter ego of various Turkish nationals”.13 The tribunal declined jurisdiction on different grounds, as it found that the Claimant did not discharge its burden of proof as to the lawfulness of the acquisition of the investment.14


In the KT Asia case, Kazakhstan argued that the Claimant indulged in abusive treaty shopping. The investor has allegedly created a Dutch company at a nominal price in view to secure treaty jurisdiction over a dispute which the investor [a Kazakh national] specifically foresaw.15 The tribunal acknowledged the possibility of piercing the corporate veil to prevent the misuse of the privileges of legal personality “assuming (…) it would require a showing of abuse of the corporate form.” The elements of abuse were not proven in this case.16

IV. Application of the doctrine of veil piercing by investment treaty tribunals


In investment treaty arbitration, this doctrine helps identify the true party in interest beyond its corporate structure. It is commonly applied where the investor seeks to gain access to a tribunal’s jurisdiction in bad faith or by using improper and fraudulent conduct.17


Since the doctrine finds its origins in national law, its status in international investment law remains debated.18 Tribunals may therefore refer to domestic interpretations of the doctrine.19 Conversely, when enforcing awards, national courts may give large deference to tribunals’ refusal to pierce the corporate veil.20


Commentators have distinguished application of the doctrine, depending on which of the two situations described by Article 25(2)(b) of the ICSID Convention is at stake21 – the first limb, which defines nationality with reference to the criteria of incorporation or seat of the corporation22 or the second limb which introduces the notion of control.23

A. Formalistic approach to corporate nationality and rejection of the doctrine of veil piercing


Tribunals have required compelling justifications to inquire into the claimant’s actual control and ownership where nationality is to be determined through the criteria of incorporation and seat of the corporation.24


In the Tokios Tokéles case, a claim was brought under the Ukraine-Lithuania BIT where 99% of the company’s shares were held by Ukrainian nationals. Respondent relied on the Barcelona Traction case, arguing that the nationality of the shareholders should be acknowledged as the true origin of the claim, in application of the veil piercing doctrine.25 By a majority, the tribunal determined that fraud or abuse of the corporate form would trigger the application of the controlling nationality test, concluding that Claimant had made no abuse in restructuring its company.26 Professor Prosper Weil, the president of the tribunal disagreed with the majority’s jurisdictional assessment (as it would depart from the object and purpose of the ICSID Convention) and resigned from the tribunal after the jurisdictional award was rendered.27


The tribunal in the Saluka v. Czech Republic case acknowledged the possibility of using an equitable remedy of piercing the corporate veil in cases “where corporate structures had been utilised to perpetrate fraud or other malfeasance” but found no application of this doctrine in the case at hand.28


In Gambrinus v. Venezuela, Respondent alleged that the tribunal should pierce investor’s corporate veil as it had structured its investment abusively i.e. that the corporate vehicle is empty, with no real connection to Barbados and is “an opportunistic shield to gain access to ICSID jurisdiction."29 The tribunal recalled that veil piercing may apply only in exceptional circumstances, and rejected the application.30 It then analysed the issue of bona fide investment in the section on jurisdiction ratione materiae, finding that the transfer of shares for the acquisition of the investment was made in breach of the agreed essential condition in the Share Purchase Agreement.31 On this ground, the tribunal declined its jurisdiction.

B. Application of the doctrine of veil piercing in relation to Article 25.2(b) second limb of the ICSID Convention


Article 25(2)(b) second limb of the ICSID Convention allows for investments incorporated in the territory of the host state to be treated as foreign nationals provided that those investments have foreign control.32 Under this provision, the Convention is concerned with the foreign control of the investment rather than its foreign ownership.


The notion of foreign control has been considered to an “objective outer limit” to the jurisdiction of the Centre that “cannot be replaced by agreement”.33 A corollary of this is that tribunals are invited to look beyond the corporate structure to identify the real foreign party in interest, embedding veil piercing into the Convention.


In the TSA v. Argentina case, the issue of “foreign control” was raised in connection with the question of the foreign nationality of the investor. Respondent objected to the jurisdiction of the tribunal under the ICSID Convention on the basis that the investment was ultimately owned by an Argentinian national. While TSA was formerly was owned by the Dutch company TSI, the latter was controlled by an Argentinian national, who held the majority of TSI’s shares. The tribunal decided to pierce the corporate veil and found that TSA could not be considered a Dutch national, because it was ultimately controlled by a national of the host State.34 Still, the extent of the doctrine’s application in terms of whether corporate layer piercing of the veil is warranted remains debated.35
