Dr. Duarte-Silva also coordinates CRA’s international arbitration group, which has been recognized by GAR as handling the second highest average claim size among expert firms and by Jus Mundi as the most active expert firm in arbitration.
Counsel and parties have noted his “outstanding contribution to our victory,” that “Tiago made a considerable contribution to our theory of the case. I would strongly recommend him to any counsel in need of a leading quantum expert,” that his “impeccable credentials and intellectual honesty grant him exceptional credibility,” and that he is “renowned for his excellent reputation in the assessment of the quantum of damages,” “very experienced and knowledgeable,” “always calm, competent, and reactive to resolve issues,” “knowledgeable, practical and creative in providing solutions,” and “quick to respond and takes ownership of the issues he works on.” He has been recognized in the past three years as the best mining expert by Lexology’s survey of in-house counsel, Client Choice Awards (“Tiago has an unparalleled grasp of how all aspects of a mining project affect valuation and the assessment.”). He is routinely listed in legal directories, such as Who’s Who Legal.
His experience in commercial and investment disputes covers quantum of lost value or profits due to breach of contract, breach of representations and warranties, direct or indirect expropriation in investment treaty arbitrations, reputational harm, and irreparable harm. He also performs valuations and forensic accounting analyses related to countervailing duties, appraisal actions, minority shareholder oppression, failing firm analyses, and various M&A disputes and price adjustments.
His expertise in securities and other financial markets disputes includes advising on market manipulation matters, fraud-on-the-market assessments, event studies, damages or settlement analyses within Rule 10b-5 and Section 11 matters, and insider trading. His testimony has led to denial of class certification and a shorter class period on market efficiency grounds, both rare outcomes.
