He authored and co-authored numerous briefs, and argued and won a half-dozen dispositive motions in federal district courts across the country. He maintained a generalist practice that involved important and novel issues of constitutional and administrative law, and handled a wide range of challenges to federal government actions, policies, and programs. His experience included litigating complex matters involving the Appointments Clause; the Spending Clause; the Territories Clause; the First, Fifth, and Fourteenth Amendments; the separation of powers; the Administrative Procedure Act; the Federal Vacancies Reform Act; and the Freedom of Information Act. He also was a member of the DOJ team that successfully defended the constitutionality of the Puerto Rico Oversight, Management, and Economic Stability Act against a challenge to the manner of appointment of the members of the Puerto Rico Financial Oversight and Management Board.
Cesar also served as a law clerk to Judge José A. Cabranes of the U.S. Court of Appeals for the Second Circuit and the U.S. Foreign Intelligence Surveillance Court of Review. Before that, he clerked for Judge Rosemary M. Collyer of the U.S. District Court for the District of Columbia, and Judge Jay A.
