Fietta LLP is a law firm dedicated to public international law (PIL) and international arbitration.  The Fietta practice comprises a unique team of specialists with broad-based experience advising States, international organisations, multinational corporations and private clients across a range of international law matters. Fietta lawyers have acted as counsel on some of the largest and most important PIL disputes of the past two decades.  They have won a number of the most substantial or significant victories seen in investment arbitration cases globally over recent years.  The firm also has a busy advisory practice, advising State (and other) clients on some of the most sensitive and important PIL issues of the day.

International Arbitration: investor-state arbitration:

Fietta LLP is one of the few law firms in the world that specialises in investor-State disputes and public international law. At all levels of the firm, our lawyers have substantial experience advising States, multinational corporations, individuals and international organisations across a broad range of international law matters. Our lawyers have won cases as counsel in treaty arbitrations across all regions of the globe. We advise on the full life-cycle of foreign investments, from the initial structuring of an investment, to the operation of an investment, the avoidance or settlement of related disputes and the pursuit or defence of arbitral proceedings on behalf of the investor or State. Fietta’s lawyers have been involved in around 50 decided and pending investment arbitration and associated court proceedings around the world. Unlike many other leading investment arbitration practices, we have acted regularly for both investor and State parties. Our lawyers have won some of the largest arbitral awards in the history of investment arbitration. In the past five years alone, our lawyers have secured four separate investment treaty merit awards worth US$100 million or more, and total awards and favourable settlements in excess of US$1.3 billion. We are regularly chosen to advise on some of the most complex and novel investor-State disputes, including those involving multiple parties and/or multiple treaties. We have acted in investor-State disputes involving a wide array of economic sectors and industries.

Public international law (advisory and contentious):

We have a leading advisory practice in public international law.  We have advised sovereign clients on many high-profile and sensitive public international law questions.  We have recently advised clients on issues of, inter alia, State responsibility, Statehood and sovereignty, sovereign immunity, treaty interpretation, law of the sea, international environmental law, foreign investment law, international human rights, international humanitarian law, State succession, international refugee law, as well as UN law and procedure. Our lawyers have represented State clients in disputes before a variety of international courts, tribunals and other dispute fora, including the International Court of Justice (ICJ), the Permanent Court of Arbitration (PCA), the European Court of Human Rights (ECtHR), the Court of Justice of the European Union (CJEU), ad hoc arbitration under Annex VII of the United Nations Convention on the Law of the Sea (UNCLOS) and ad hoc mediation under the auspices of the United Nations.  We have also represented State clients in a range of public international law cases before domestic courts. Our State clients have enjoyed a positive outcome (win or positive settlement) in all concluded State-to-State disputes in which we have acted as counsel. A number of our State representations have involved disputes over territorial sovereignty, the delimitation of land and maritime boundaries, environmental damage and human rights.  We are uniquely equipped to assist with the management, coordination and advocacy of such complex, multifaceted and sensitive cases, or in the conduct of negotiations prior to invocation of third-party procedures.
