Government of the Republic of the Philippines, challenge to Government's revocation of a concession for Manila international airport terminal (ICSID and ICC), ongoing

Carolyn represented the Government of the Republic of the Philippines in a treaty-based ICSID arbitration, 'Fraport v. Philippines', and in an ICC arbitration, 'PIATCO v. Philippines', as a result of the alleged nullification of a concession contract and expropriation of an international air terminal with claims jointly in excess of US$1 billion. In PIATCO, the Tribunal dismissed all claims and the Singapore High Court rejected the claimant's petition to set aside the tribunal's decision. In Fraport, the tribunal dismissed all the claimant's claims for lack of jurisdiction. Carolyn continues to represent the Republic in the dispute, which has been submitted to a new ICSID tribunal.

Abaclat & Others v. Argentine Republic (ICSID), ongoing

Carolyn is representing tens of thousands of Italian holders of Argentine bonds in a US$2.5 billion ICSID arbitration under the Argentina-Italy bilateral investment treaty. The case relates to sovereign default, a critical legal and political issue in Latin America, and involves the largest known number of claimants in a single arbitration. In August 2011, the tribunal issued a seminal 283-page 'Decision on Jurisdiction and Admissibility', establishing jurisdiction over the claims – finding that sovereign bonds are protected investments and giving the green light to the first-ever mass claim in investment arbitration history. The decision won Most Influential Award of the Last Decade at the 2012 OGEMID Awards.

Grupo Unidos por el Canal, S.A., major construction dispute (ICC), ongoing

Carolyn is representing joint venture company Grupo Unidos por el Canal, S.A. in a dispute with the Panama Canal Authority over the US$5.5 billion Panama Canal expansion project (which encompasses the construction of a cofferdam as part of the mega Panama Canal expansion project: the "Third Set of Locks Project"). Carolyn and her team initially intervened to negotiate a resolution to a crisis that stalled construction of the project, and are now advising on the completion of the project and long-term disputes to resolve liability, including contract renegotiations, a Dispute Adjudication Board proceeding, an ICC proceeding and a Bilateral Investment Treaty arbitration proceeding.

Government of the Republic of the Philippines, environmental claim (ICSID), ongoing

Carolyn is defending the Philippines in an ICSID claim brought by a Belgian dredging company, Baggerwerken Decloedt en Zoon, relating to the termination of a €300 million project to rehabilitate the country's largest lake. The claim is made under the Belgium/Luxembourg-Philippines bilateral investment treaty.

Metal-Tech Ltd. v. Republic of Uzbekistan (ICSID), 2013

Carolyn represented the Republic of Uzbekistan in an ICSID arbitration arising under the Uzbekistan-Israel bilateral investment treaty brought by an Israeli company, concerning a joint venture that was engaged in the processing of molybdenum, a metallic mineral. In a unanimous award, the tribunal refused jurisdiction over Metal-Tech's request for more than US$170 million for alleged treaty violations, finding that Metal-Tech made corrupt payments to obtain its alleged investment in the Uzbek molybdenum industry. The case is the first-ever investment treaty claim before ICSID to be dismissed on corruption grounds. The decision was nominated by Global Arbitration Review for "Most Important Published Decision of 2013 in Jurisprudential Terms".

Government of Bulgaria, ICSID Arbitration, 2012

Carolyn represented the Government of Bulgaria in an ICSID arbitration, 'Plama Consortium v. Republic of Bulgaria', under the Energy Charter Treaty and Bilateral Investment Treaties of claims of over US$100 million, arising from the privatization of an oil refinery project. Through Carolyn's efforts, the case was dismissed and Bulgaria won a substantial cost award.

Republic of Peru, electricity transmission and legal stability dispute, 2011

Carolyn represented Peru in Aguaytia Energy, 'LLC v. Republic of Peru', an ICSID arbitration of a dispute involving electricity transmission and legal stability agreements in Peru. Her successful defences of Peru resulted in the dismissal of the case and the dismissal of the investor's claims – which totaled in excess of US$100 million.

PSEG Global Inc. & Another v. Republic of Turkey (ICSID), 2007

Carolyn represented PSEG Global Inc. and Konya Ilgin Elektrik in an ICSID arbitration arising under the US-Turkey bilateral investment treaty involving an investment in Turkey's electric power industry. Carolyn defeated Turkey's efforts to dismiss the case on jurisdictional grounds and then obtained a US$21 million ICSID award in favor of the claimants, including an award of costs of US$4.6 million.

Tribunal Member, Canadian ICSID claim against the US, 2003

Carolyn served as a member of the arbitral tribunal in the case of 'ADF Group Inc. v. United States of America', an ICSID Additional Facility arbitration filed by a Canadian investor under chapter 11 of the North American Free Trade Agreement.

Republic of Indonesia, foreign licence revocation (ICSID), 1990

Carolyn represented the Republic of Indonesia through the final stages of the first trial, annulment proceedings and resubmission proceedings (including the retrial) of 'Amco Asia et al. v. Republic of Indonesia', ICSID Case No. ARB/81/1, which resulted from the revocation of a foreign investment license that permitted an investor to construct and operate a hotel in Jakarta. The case raised numerous issues of first impression and remains to date one of the most heavily cited cases in the investor-State context. Through Carolyn's efforts, the first award was annulled, the second award was partially annulled and the damages were significantly reduced.
