Cesar is an appellate lawyer who litigates key legal issues in high-stakes appeals and dispositive motions in courts across the country.
As a member of the firm's Supreme Court and Appellate group, Cesar draws from his experience at both the trial and appellate level to develop legal strategy, advise clients, and draft persuasive briefs. He is a skilled brief writer who specializes in simplifying complex concepts and crafting a compelling story that frames factual and legal issues in a way that is more likely to produce favorable results for clients.
Cesar has co-authored numerous briefs in federal and state courts of appeals, and at both the certiorari and merits stage in the U.S. Supreme Court. And he is often embedded at the trial level to brief dispositive motions, and to make sure that issues are preserved and that the record is properly developed with an eye towards appeal. His work covers a wide range of substantive areas, including constitutional and administrative law, statutory interpretation, complex commercial litigation, and federal preemption (particularly, in the false claims, products liability, and arbitration context). He also maintains an active pro bono practice, representing immigrants and veterans in their appeals to the federal courts of appeals and filing amicus briefs in precedent-setting cases of public interest. He is especially passionate about advancing the rights of the residents in the U.S. territories.
Before joining Orrick, Cesar was an attorney at the U.S. Department of Justice's Civil Division, Federal Programs Branch, where he represented the United States and its agencies in dozens of cases involving challenges to the legality of federal laws, actions, and programs. He authored numerous briefs and argued and won dispositive motions in federal district courts nationwide. His experience included litigating cutting-edge matters involving the Appointments Clause; the Spending Clause; the Territory Clause; the First, Fifth, and Fourteenth Amendments; the separation of powers; the Administrative Procedure Act; the Federal Vacancies Reform Act; the Freedom of Information Act, and the Puerto Rico Oversight, Management, and Economic Stability Act.
