Mr. Herlihy was named as a 2019 International Arbitration MVP by Law360 (a ranking of its five most successful arbitration lawyers worldwide for that year). Additionally, Chambers UK and The Legal 500 identify
him as a leading individual in his field, describing him as a “fantastic arbitration lawyer,”
“a powerful and eloquent advocate,” “amazingly skilled” and “frankly outstanding.” He has a broad range of experience in commercial and investment treaty disputes across multiple industries, including Spanish-language disputes in Europe and Latin America.
His representations include acting for:
Investment Treaty Arbitration/Public International Law
- Vodafone International Holdings B.V. in its landmark victory against the Republic of India under the Netherlands-India bilateral investment treaty. In its September 2020 award, an UNCITRAL tribunal held that India’s attempt to impose a $5.5 billion liability onto Vodafone and its Indian subsidiary — through retroactive withholding taxes, interest and penalties — was in breach of international law;
- the Republic of Cyprus in its successful defence of ICSID claims arising out of its regulatory treatment of the nation’s second-largest bank during the eurozone financial crisis. In a 2018 award rendered under the Cyprus-Greece bilateral investment treaty, an ICSID tribunal upheld Cyprus’ defences in full, rejected claims by the bank’s former shareholders that had sought more than €1 billion in damages, and awarded costs in favour of Skadden’s client;
- NextEra Energy Global Holdings B.V. and NextEra Energy Spain Holdings B.V. in the successful prosecution of claims against Spain under the Energy Charter Treaty. In a 2019 award, an ICSID tribunal awarded our clients damages of €292 million plus attorneys’ fees, making this the largest damages award against Spain in the renewable energy sector;
- the Slovak Republic in its successful defence of a bilateral investment treaty dispute involving claims in excess of €1 billion, a result named as one of The American Lawyer’s five Biggest Defense Wins in its global survey of international arbitration for 2011-13;
- Global Telecom in an investment treaty dispute against Algeria concerning the treatment of its subsidiary Djezzy resulting in a settlement and joint venture agreement under which Skadden’s client received net cash payments of US$3.8 billion;
- the Republic of South Sudan in its oil sector negotiations and related international law issues following its secession from the Republic of Sudan, as well as in ICSID proceedings brought by Sudapet Co. Ltd. concerning the disputed ownership of significant oil field interests (disputed amount exceeding US$1 billion). Legal Business named Skadden as its 2017 International Arbitration Team of the Year for the defence of this case;
- the Republic of South Sudan in the recovery of substantial sums representing the proceeds of shipments of crude oil misappropriated by the Republic of Sudan. For this work, Skadden was commended by the Financial Times in its 2013 Innovative Lawyers report for Europe and the firm also was named African Legal Awards’ Dispute Resolution Team of the Year in 2013;
- investors Ron Fuchs and Ioannis Kardassopoulos in ICSID arbitration proceedings against Georgia under the Energy Charter Treaty and two bilateral investment treaties, resulting in a damages award of US$100 million and a landmark precedent concerning the provisional application of that treaty. This matter received a Global Arbitration Review award in 2012;
- foreign investors overseeing enforcement of an ICSID award against a state’s commercial assets worldwide;
- a French investor in ICSID claims concerning the treatment of a foreign bank;

Mr. Herlihy also acts as counsel in court proceedings arising out of international arbitrations, including applications for interim injunctions under the Arbitration Act 1996 and anti-suit injunctions in the U.S. federal courts. He is also experienced in litigating high-value international disputes before the English High Court and the Courts of the British Virgin Islands, often involving novel issues of conflicts of laws and forum non conveniens. Examples of these cases include Sibir Energy v. Roman Abramovich, Sibneft & Ors. (High Court, BVI) and Kolden Holdings Ltd v. Rodette Commerce Ltd and Another (High Court, England & Wales). In addition, he has advised on a variety of dispute resolution issues in the U.S., England and internationally, including potential claims under the European Convention on Human Rights and the treaty establishing the Common Market for Eastern and Southern Africa.
