Excellent team of lawyers specialising in mediation and arbitration. Able to distill issues and move them forward expertly and efficiently.

Jonathan Hamilton is a standout lawyer, able to fairly but robustly bring many views around the table into the right step forward whilst at all times managing expectations and diplomatically delivering the “tough” messages. I would want him on my side in a difficult dispute resolution.

I think that one of the greatest strengths of this team in Washington DC, and especially of its Latin American arbitration practice is based on its particular knowledge about this region and the way in which disputes develop there. White & Case’s Latin American arbitration team in Washington is undoubtedly a benchmark in the market.

In addition to having a highly qualified team, I emphasize the human factor and the relationship with the client. Working with White & Case has been a real pleasure for us since we have been able to stay in contact during our processes in a clear and continuous way. The team is always open and available to answer our questions and concerns. I highlight John Dalebroux as an associate who in particular has had a very close and professional relationship with our team at all times.’

Practice head(s):

Eduardo Silva Romero


Dechert’s practice of international arbitration is exceptional! They have a good eye to design the best procedural strategies.

A key feature for Dechert’s international arbitration practice is that the team is international. Team members are from all over the world; thus, they speak different languages and, most importantly, they understand different cultures and their unique characteristics. When a company or a country has a cross-border dispute, it is essential to retain an external counsel who understands cultural issues that may affect the case. No other international arbitration practice has those characteristics, only Dechert’s.

Eduardo Silva’s leadership is unmatched. The team works synchronously following his strategic decisions.

Highlighted for its track record and international prestige, expertise in different venues of arbitration, extensive knowledge and access to key players. Excellent ability to define case strategies, with economic knowledge of the law.

José Manuel García Represa: in my experience, there are not two like him. His ability to understand, explain, and find, in detail, the strengths of a client’s case and the shortcomings of your opposition is something I have not seen in other attorneys. Certainly, these capabilities make him an outstanding court examiner.

Eduardo Silva Romero is a star. He is a leading authority in international arbitration. In addition to being an expert in arbitration and public international law, his professional career is an absolutely relevant asset before an arbitral tribunal. Certainly, his strategic abilities are amazing. His vision and strategic decisions make the difference in the course of arbitrations. He has the extraordinary ability to focus on the truly relevant of the case.

Arif Ali is an extraordinary strategist. In addition, he has unique knowledge of disputes related to Eastern Europe and Asia, as well as the energy industry. It has the great virtue of making complex things quite simple in court.

Juan Felipe Merizalde: I have not seen the legal and leadership capacities of Juan Felipe in other lawyers of his age. It is also rare to find such a young lawyer with so much recognition among his peers and in the international legal market. I know, for sure, that he is the right hand man of both Eduardo Silva Romero and José Manuel García Represa and the key associate in Dechert.

José Astigarraga, Eduardo de la Peña Bernal, Cristina Cardenas and Sujey Herrera form a great team of experts in international arbitration.

The great work they do, they study all the possibilities and answer all the questions in the case and prepare you on how to make statements in court.

Vinson & Elkins LLP

Clients praise the 'highly sophisticated' service provided by Vinson & Elkins LLP, and that seems 'better prepared and more knowledgeable' than most other firms handling Latin American international arbitration work. Its predominant caseload features commercial claims and arbitration opposing states and state-owned entities following breaches of investment guarantees and/or treaty agreements – most frequently in relation to transactions in the energy or oil-and-gas segments. The team also continues to receive instructions from the Panama Canal Authority regarding proceedings with Grupo Unidos por el Canal, and other contractors, in relation to aspects of the canal's expansion project. Houston-based practice head James Loftis, who 'combines comprehensive legal knowledge, strategic thinking and remarkable availability', recently ensured a successful outcome for Exxon Mobil in its long-running bilateral treaty dispute with Argentina alongside the 'accomplished' London-based Nick Henchie. Elsewhere, the 'sophisticated and pragmatic' New York-based Camilo Cardozo is representing Prime Energia regarding design and construction contracts for five Chilean power plants. Cardozo and of counsel José Sanchez (noted for his 'fastidious attention-to-detail')are also acting for Offshore Exploration and Production against government-owned oil-companies from Colombia and South Korea.


I think the best thing about this team is that they are very good at what they do while being very cost-effective. We have worked with more than five large law firms on international arbitration matters and this is by far the most effective team we have worked with. This team does very good work for a fraction of the price that those other firms charge.

Our team at Vison & Elkins consists of Camilo Cardozo and Jose Sanchez. Camilo previously represented our firm in connection with an arbitration in Chile against a former licensee of our firm in Colombia. This team has shown its ability to break down complex legal issues in a manner that makes it easy for arbitrators to understand our positions. For us, the ability of this team to work with and understand conflicts in Latin America, has been key.

The team is fantastic. They are superb lawyers. Not only are they excellent lawyers, but they are also incredibly professional. They always give me complete confidence in their work. I have seen other firms that have represented clients opposed to us in international arbitrations, and in my opinion this team is always better prepared and more knowledgeable.

Highly sophisticated team with superior knowledge of the intricacies of international arbitral bodies and practice.

They are highly professional, detailed and responsible. Apart from the great knowledge they have of the subject, they surpass teams from other offices.

We have hired Camilo Cardozo and Jose Fernando Sanchez; who currently direct and are part of the international arbitration practice of Vinson & Elkins LLP; together they make a team with a deep legal structure and extensive knowledge of international arbitration procedures, which is why I consider that Vinson & Elkins LLP has an excellent international arbitration team.

Jose Sanchez is the lawyer leading our cases. Jose is an outstanding lawyer. I have worked with him on and off on several arbitrations since 2011, so I know his working style very well. He always masters all the facts and arguments better than any other lawyer on either side of the case. He is sophisticated, creative, and relentless. I’ve worked with several big US law firms and lawyers over the years on our international arbitration matters, and one big source of frustration for me has always been how those firms add up their legal fees so quickly. That has never been a concern with Jose. He is extremely efficient.

I have worked with Jose F Sanchez and Camilo Cardozo on three separate arbitrations that they have handled for us. I truly value and admire Jose as a lawyer, and will continue to trust him with our international arbitration matters. He is always attentive to every detail and is always thinking of ideas and arguments that no one else was thinking of and that strengthen our position on the cases. Throughout the years and the different cases Jose has handled for us, he has never been outworked by any other lawyer. On the contrary, he is always several steps ahead of all other lawyers on either side. I have also worked with Camilo Cardozo, who I also trust and respect as a lawyer, because he is both sophisticated and pragmatic.’

Jose Sanchez, in particular, stands out for his stellar work. Very conscientious and forward-thinking, with fastidious attention to detail. Superior job of communicating about timing, scope and parameters. Phenomenal final work product.

Nick Henchie has always stood out as a very accomplished lawyer and litigator.

Jim Loftis combines comprehensive legal knowledge, strategic thinking and remarkable availability and involvement in the matters. Tim Tyler has a thorough command of the cases, which ensures a smooth management of the matters.

José Fernando Sanchez is a great professional. He is an expert lawyer in Colombian and American law, very agile and creative. He is very studious, so his answers always have a lot of elaboration and success.

Baker Botts L.L.P.

The Baker Botts L.L.P. international arbitration team does 'an extremely meticulous job' and 'makes a difference with attention-to-detail' for clients in the oil and gas, energy and construction sectors. Key contact Alejandro Escobar heads the practice alongside Jay Alexander in London, and Michael Goldberg in Texas, while Andrew Behrman provides strong support from the New York office on contracts disputes. Escobar is 'a lawyer who differs from the rest' with an ability to 'improvise in the face of unforeseen events', having recently represented the Republic of Ecuador in a successful defence claim against Spanish investor Albacora, concerning income tax exemptions under a bilateral investment treaty. Further cases concern state-owned entities and various project companies. 2019 saw a couple of personnel changes, as Dorine Farah made partner in January and Poupak Anjomshoaa joined from Norton Rose Fulbright in March.


They do an extremely meticulous job. Their attention to detail is amazing. I have had the opportunity to work with several law firms in international arbitrations and Baker Botts definitely makes a difference with attention to detail and the depth in which they analyze each case. They have a very careful working methodology, characterized by their organisation.

Alejandro Escobar is undoubtedly a lawyer who differs from the rest. His experience, ability to work under pressure and improvise in the face of unforeseen events is absolutely remarkable. As are his knowledge of legal principles and institutions of law in general. He has an extraordinary general legal culture. The great difference between Baker Botts and its competitors, I think, is in its organization and planning. They don’t leave details to chance.

I have worked with Ignacio Suarez Anzorena (partner) and José García Cueto (special adviser). Both are exceptional attorneys. Their experience in arbitration is essential to determine how to face a controversy, present the case, select arbitrators and experts. They also know the sector very well, which allows them to project how the defense of the counterparty will act in arbitration.

José García Cueto excels in this office, he is a very competent lawyer and takes each case with a high professional level and commitment, especially since he works very hard to achieve the goals that are set. I am more than pleased with him.

The professionals in charge of the practice have a deep knowledge of international arbitration. The team handles all aspects very well. It is difficult to point out any weak point in the team. The team has the same level as the best world firms in the field of international arbitration.

They know their subject with a depth of analysis that shows much rigor in their opinions and in the preparation and monitoring of their cases. Ignacio Suarez Anzorena and José García Cueto have a very personalized treatment and constantly study innovative options for their clients.

New York-based Benard Preziosi Jr and Washington DC-office managing partner Claudia Frutos-Peterson are also key contacts, with the team further recommended for its 'highly prepared structure and excellent client management'.


Their expertise in arbitration, national and international, is significant. They know arbitration, institutional and ad hoc procedures, from the perspective of both the party’s attorneys and arbitrators, and from both a theoretical and practical point of view.

They have more experience than other firms in handling complex matters, with a highly prepared structure and excellent client management. I would mention Ben Preziosi, Mark O’Donoghue, Gabriela Ãlvarez-Ãvila and Claudia Frutos-Peterson.

Gabriela Ãlvarez-Ãvila, ex-ICSID counsel, is outstanding.

Curtis is one of only a very few firms (two?) that represent only host governments in investor-state dispute settlement [ISDS] cases. As a result, its positions across cases are not in conflict. It is superb at building a team of lawyers and experts that are dedicated to the case and who work well together.

George Kahale is simply superb, in terms of sheer intelligence, knowledge of the field, ability to manage a team, and dedication to his clients. Ben Preziosi is a close follow-up.

Recent work highlights, led by Torterola, involve defending the Bolivarian Republic of Venezuela; firstly, following various expropriations of companies allegedly owned by food distribution claimants, as well as in a matter concerning the State's prior denunciation of the ICSID Convention.


The firm has a vast and unique experience in complex international disputes. It has worked on more investment cases than most firms in the world.

Diego Gosis, Ignacio Torterola and Quinn Smith are enormously reliable and strategically gifted for complex disputes. Their hands-on approach to their cases leads to fantastic results.

The main characteristic of all the lawyers at the firm (regardless of hierarchy) is the ability to problem-solve, and proactivity. They are always available and have a knowledge of law that exceeds the specialty of international law.

At GST, most attorneys, including the youngest, have extensive legal knowledge. On the other hand, their variety of lawyers with different backgrounds and provenance means that the approach regarding the different topics can be carried out considering the legal systems of different countries.

B. Cremades & Asociados

B. Cremades & Asociados' work highlights include various ICSID proceedings, with the team currently acting for Blue Bank International & Trust (Barbados) against the Republic of Venezuela in a $400m award annulment case; as well as representing Inversiones Continental against the Republic of Honduras, in a case arising from the State's forced liquidation of Banco Continental. Founding partner Bernardo M Cremades S heads the entirely Madrid-based practice alongside Bernardo Cremades Román; both specialise in major construction and infrastructure-related investment treaty and commercial arbitrations. Other matters involve clients from the energy, gaming and pharmaceutical sectors, with Ángel Tejada a further contact of note. David Cairns left the firm in January 2020 to become a full-time independent arbitrator at the IAC.


The team at Cremades that attends to arbitral proceedings and contentious matters in general is exceptional. The lawyers’ knowledge of the norms of international arbitration is excellent.  Their dedication to the details of the proceedings and to ensuring that the proofs are of sufficient strength to ensure success, make them in my opinion- the outstanding option among all the firms with which i have had the pleasure to work.

I am referring to the following partners and associates with who I’ve worked at the firm: Bernardo Cremades Román, José María López Useros y Paloma Carrasco García. They are incisive and very analytical of the procedural details, and very clear in their explanations and details regarding the strengths and weaknesses of the proofs and arguments of the parties of the cases they undertake. The added-value that makes them stand out is their ability to anticipate the differing circumstances that could arise in the course of the proceedings and in their rapid response before such situations.

Mexico City-based Kate Brown de Vejar and Paris-based Michael Ostrove act as global co-chairs of the 'exceptionalDLA Piper LLP (US) international arbitration department, with assistance from Buenos Aires-based Mariana Lozza. With energy and construction matters its predominant focus, the practice continues to represent Metro de Lima Línea 2 in ICSID proceedings arising from a PPP project against the Republic of Peru, and recently began advising LAMSAC over alleged contractual breaches by Construtora OAS during the design and execution of works on the Línea Amarilla road system. Benefiting from a network of offices across the region, the team also has experience with various Latin American bilateral and multi-lateral investment treaty disputes, with clients identifying Brown de Vejar as 'outstanding' in this domain – with 'her focus, insight and strategic direction' making her 'best-in-class'.


The DLA international arbitration team is exceptional. The lawyers work particularly well across geographies and the way they have coordinated between the Americas and Japan offices has, for us, been very impressive.’

Kate Brown de Vejar is outstanding. Our firm finds that her focus, insight and strategic direction are best in class. Every interaction is the very definition of professionalism.

The team know the technicalities in detail and that gives the greatest security. They translate complex legal matters in a simple way. As legal in-house for me it is simple to understand, but for the other departments it is complex and DLA Peru creates a bridge.

Holland & Knight

Holland & Knight's 'well-established' international arbitration practice works primarily with clients from the mining, energy and construction sectors, along with various repeat sovereign-state clients. Led by Miami-based Adolfo Jiménez, who acts as sole or co-arbitrator in ICC and ICSID hearings, the team' most recent highlight involved representing the Republic of Guatemala against two US parties responsible for silver and gold mines in La Puya. The team also continues to handle French-side proceedings, opposing the Mexican government, in light of Eutelsat bilateral investment treaty breach claims. Bogotá-based Enrique Gómez‐Pinzón and Alberto Zuleta Londoño (who divides his time between Bogotá and Miami), are further key contacts, while Katharine Menéndez de la Cuesta and Orlando Segura, who both made partner in January 2020, are also active in the area. Salvador Fonseca – the firm's previous head of dispute resolution in Mexico – left to join Fonseca, Rodríguez & Perchemlian Abogados, S.C.  in June 2020.


Preliminary observation: my knowledge of the team is limited to the fact that several of their lawyers have represented clients in cases where I was an arbitrator, or have co-arbitrated cases with me. It is a very well established and suitable firm, especially for maritime and construction disputes in Latin America.

Adolfo Jimenez, Marisa Marinelli and Katharine Menendez de la Cuesta are tireless, persuasive and educated lawyers.

A team of great professionalism and prestige. They are the best in Europe at this type of work.

In particular, I would like to highlight the quality of the work carried out by Pablo, his level of knowledge of the case, his analytical capacity, work capacity, commitment and self-demand, which make him an excellent collaborator. On the other hand, the training and level of preparation of the rest of the people of Uria & Menéndez involved in the case have been exceptional.

Practice head(s):

Robert Volterra


The team is diverse and works with a lot of developing countries. The diversity on the staffing helps the firm to be sensitive to realities in developing countries. The team is also well versed on matters of arbitration involving developing countries.

Robert Volterra is thoughtful yet frank. He paints an accurate picture of the situation and comes up with real solutions. He is also very knowledgeable about international law, in particular maritime boundary disputes. He makes himself available and replies promptly to queries.

This practice specialises in public international law, and I think is unique in the extent to which it does so. Inevitably, this means that it has a very high level of expertise in that field, and is extremely well connected with its practitioners worldwide, including government officials.

Robert Volterra, a founding partner, comes with a great deal of experience in other law firms (including Latham and Watkins) and combines high intellectual ability with very good practical judgement. His partner Graham Coop, is a very experienced New Zealand barrister who, immediately before joining Volterra Fietta, was General Counsel to the Energy Charter Secretariat, a highly responsible post. Graham Koop is a very careful lawyer whose judgement I respect. Alvaro Nistal, counsel, is a young lawyer both Spanish and English qualified (among other things, this gives the firm the capability of dealing with Latin American issues); my experience of him is that he is an energetic and capable lawyer. Over the years I have had dealings with a number of the firm’s associates, who all seem very able. For example, Govert Coppens and Gunjan Sharma..
