GBS Disputes

Yael is or was part of the team advising and/or representing:

Investment Disputes

• The Republic of Peru, Respondent in an ICSID arbitration initiated by Bank of Nova Scotia (ICSID Case No. ARB/22/30), concerning a nearly 15-year long tax dispute relating to a tax claim by Peru’s tax authority. The claims are brought under the Canada-Peru Free Trade Agreement. Peru filed an application under ICSID Arbitration Rule 41, arguing that the Bank of Nova Scotia’s claims were manifestly without legal merit. The majority of the Arbitral Tribunal upheld most of these objections and dismissed the Bank of Nova Scotia’s claims for expropriation and violation of the minimum standard of treatment. The arbitration proceeding will continue only in relation to the Bank of Nova Scotia’s national treatment claims.
• The Republic of Colombia, Respondent in an ICSID arbitration brought by Angel Samuel Seda and others (ICSID Case No. ARB/19/6). The dispute arose from allegations of expropriation of a real estate project seized in application of Colombia’s asset forfeiture law, and claims in excess of USD 300 million were brought under the 2012 Colombia-U.S. Trade Promotion Agreement (TPA). In a landmark victory for our client, the Tribunal dismissed all claims and found, for the first time in investment arbitration history, that the essential security clause in the TPA invoked by Colombia applied and protected Colombia’s measures designed to fight narcotraffic and money laundering.
• The Republic of Colombia, Respondent in an ICSID arbitration brought by engineering company CB&I UK (ICSID Case No. ARB/22/11). The dispute related to a refinery expansion project and the claims were brought under the Colombia-UK bilateral investment treaty.
• The Republic of Lithuania, Respondent in an ICSID arbitration brought by Veolia Environnement S.A. and others in relation to district heating and power generation systems in Lithuania (ICSID Case No. ARB/16/3). The claims are brought under the Lithuania-France bilateral investment treaty.
• A leading European energy group in a UNCITRAL arbitration against the Kingdom of Spain under the Energy Charter Treaty. The dispute related to measures taken by Spain in the renewable energy sector.
• The Arab Republic of Egypt, Respondent in two investment arbitrations concerning alleged violations under the Egypt-Poland, Egypt-U.S. and the Egypt-Germany bilateral investment treaties relating to the performance of a long-term contract for the export of Egyptian natural gas to Israel. Around USD 2 billion was claimed. More than two thirds of the claims were dismissed on jurisdictional grounds and on the merits. Following these decisions, the parties reached a global settlement, under which all claims against our clients were waived without our clients being required to make any payment.

Commercial Disputes

• Subsidiaries of a Gulf sovereign wealth fund in an ICC arbitration in Switzerland initiated against related companies of a European real estate investment group and its ultimate beneficial owner. The dispute arises from the breach of various finance agreements. Over EUR 700 million are at stake. The law of the Respondents’ State of nationality applies.
• The Latin American subsidiary of a European energy company, Claimant in an ICC arbitration in Paris against a European LNG supplier. The dispute arises from an LNG Sale and Purchase Agreement. New York law applies.
• A leading European energy company and its Asian subsidiary, Claimants in an ICC arbitration in Singapore against three Asian State-owned nuclear power companies. The arbitration concerned a shareholders’ dispute arising from the unilateral adoption by the Asian companies of accounting rules for the joint venture which would have had the effect of preventing our client from receiving its share of profits generated by the nuclear power plant throughout the assets’ technical life. The law of the Respondents’ State applied. The Tribunal found that the accounting rules adopted by the Respondents were in breach of the shareholders’ agreement, issued relief to protect our clients’ share of future profits, and ordered the Respondents to pay 75% of our clients’ legal fees.
• International Petroleum Investment Company (IPIC) (an affiliate of Mubadala Investment Company PJSC), Respondent in an ICC arbitration in Paris initiated by Real Madrid football club. The dispute arose from a sponsorship agreement related to the Santiago Bernabéu stadium. Spanish law applied and over EUR 550 million was at stake. The Arbitral Tribunal, ruling by a majority, dismissed Real Madrid’s EUR 550 million claims in their entirety.
• Two State-owned entities in a USD 6 billion ICC arbitration in Geneva and a USD 4 billion CRCICA arbitration in Cairo arising out of a long-term gas supply contract relating to the export of Egyptian gas to Israel. English law applied to both arbitrations. More than three quarters of the Claimants’ claims were dismissed for lack of jurisdiction or on the merits. Following these decisions, the parties reached a global settlement for less than five percent of the claim.
