Reuben J. Sequeira

Counsel, Washington, DC

Biography

Overview

Reuben Sequeira advises private companies, sovereigns, and multilateral institutions in the resolution of international disputes. He represents clients in litigation before US trial and appellate courts, in investigations brought by US government agencies, and in international arbitrations. Mr. Sequeira regularly advises on and litigates legal issues of first impression. Having both a financial and technical background, he provides clarity where disputes involve complex factual issues.

Many of Mr. Sequeira's matters concern issues particularly important to foreign entities and sovereigns: the extraterritorial applicability of US law, US courts' limited authority to assert jurisdiction over foreign defendants, and, conversely, the ability of foreign plaintiffs to assert claims in US courts. Mr. Sequeira has litigated and advised on these issues in the context of, for example, US securities laws, US anti-terrorism laws, and sovereign immunity matters.

In addition to litigation, Mr. Sequeira leverages his past experience with data systems, financial accounting, and analytics to optimize the execution of internal investigations, including, for example, regarding compliance with sanctions, anti-money laundering (AML), and counter-terrorism financing (CTF) regulations and standards.

Based on his extensive experience with the US Anti-Terrorism Act (18 U.S.C. § 2333, et seq.), Mr. Sequeira provides pro bono advice to international NGOs on compliance with US anti-terrorism laws.

Mr. Sequeira is based in Washington, DC.
