Experienced, Full-Time Arbitrator

Antolín Fernández Antuña

Three Key Qualities



In international arbitration, where stakes are high, the parties diverge considerably in their interpretation of matters of law, and even more so in their approach to the financial core of the dispute.

As a matter of fact, this gap between the parties represents on average 88% of the total claim (PwC International Arbitration Damages Research).

This entails the imperative need to deal with the complex quantum reports presented by the opposing parties, as they are the very foundation of the award.

It therefore stands to reason, particularly in light of the fact that approximately one of two awards results in compensation, upholding claims in part or in full (ICSID caseload Statistics), that arbitrators should possess the best possible financial knowledge.

This is where Antolín Fernández Antuña’s varied academic background and his hands-on experience with the Ministry of Economy and Public Finance since 2004 and investment arbitration cases (Ministry of Justice), combine to offer a unique blend of skills in both Law and Finance.

Furthermore, his profile is characterized by his full-time dedication to his work as an arbitrator.
