Procedural Background and Key Issues

This document is the final Award of the Tribunal in an ICSID arbitration initiated by two Cypriot companies, ADC Affiliate Limited and ADC & ADMC Management Limited, against the Republic of Hungary. The dispute arose from the alleged unlawful expropriation of the Claimants' investment in the development and operation of the Budapest-Ferihegy International Airport. The claims were brought under the Agreement between the Government of the Hungarian People’s Republic and the Government of the Republic of Cyprus on Mutual Promotion and Protection of Investment (the "BIT").

The Tribunal addressed three principal sets of issues: (i) its jurisdiction over the dispute, particularly concerning the definition of "investor" and "investment" under the BIT and the ICSID Convention; (ii) the merits of the expropriation claim, including whether Hungary's actions were justified as a legitimate exercise of regulatory power; and (iii) the quantum of damages, focusing on the applicable standard of compensation and the appropriate valuation methodology.

Jurisdictional Findings

The Tribunal affirmed its jurisdiction over all claims. It rejected Hungary's primary jurisdictional objection that the Claimants, being ultimately owned and controlled by Canadian nationals, were not genuine Cypriot investors entitled to BIT protection. The Tribunal held that the plain text of the BIT and the ICSID Convention established nationality based on the state of incorporation (Cyprus). It found no "genuine link" requirement in the applicable BIT and declined to "pierce the corporate veil," noting that Hungary was fully aware of and had consented to the investment structure. The Tribunal also confirmed that the Claimants' rights, including their shareholding in the project company and their entitlement to management fees, constituted a protected "investment" and that the dispute arose "directly" therefrom.

Decision on the Merits

On the merits, the Tribunal found that Hungary had unlawfully expropriated the Claimants' investment in breach of Article 4 of the BIT. The expropriatory act was identified as the enactment of legislative amendments and a Ministerial Decree in December 2001, which terminated the project company's rights to operate the airport terminals without compensation. The Tribunal systematically dismissed Hungary's justifications, including the alleged need to harmonize with EU law, national security, and strategic interests, finding them to be unsubstantiated and serving as *ex post facto* rationalizations. The Tribunal concluded that the taking was not for a public purpose, was discriminatory, lacked due process, and was not accompanied by just compensation, rendering it an unlawful act under international law. The Tribunal also found that Hungary's conduct breached the fair and equitable treatment (FET) standard under Article 3 of the BIT.

Quantum and Relief

For the assessment of damages, the Tribunal held that the standard for an unlawful expropriation under customary international law, as established in the *Chorzów Factory* case, was applicable. This standard requires reparation to wipe out all consequences of the illegal act, effectively restoring the claimant to the position it would have been in but for the breach. Consequently, the Tribunal determined that the valuation date for the investment should be the date of the Award, not the date of expropriation, to account for the investment's subsequent appreciation in value. It adopted the Discounted Cash Flow (DCF) methodology advanced by the Claimants' experts. The Tribunal awarded ADC Affiliate US$55,426,973 and ADC & ADMC Management US$20,773,027, plus post-award interest. It also ordered Hungary to pay the Claimants' full legal costs of US$7,623,693. The award was conditioned upon the transfer of the Claimants' shares in the project company to Hungary upon full payment.
