He is an expert in administrative law, criminal law, international law, public organizations, and the law of public health and safety. He is currently the Stanley Morrison Professor of Law at Stanford Law School and the Director of Stanford's Freeman Spogli Institute for International Studies. He has been the Co-Director of Stanford's Center for International Security and Cooperation. On July 22, 2014 Governor Jerry Brown nominated Cuéllar to the California Supreme Court. His is the second nomination of Governor Brown's third term.
Early life and education
An American citizen, Cuéllar was born in Matamoros, Tamaulipas, México, and attended junior high school in Brownsville, Texas. When he was in high school, his family moved from Texas to the city of Calexico, in California’s Imperial Valley.
Cuéllar's research and teaching focus on administrative law, criminal law, executive power, and how organizations implement regulatory responsibilities involving public health and safety, migration, and international security in a changing world. Before joining Stanford Law School, Cuéllar worked at the U.S. Department of the Treasury, where he focused on anti-corruption initiatives, border coordination, and financial crime enforcement. He clerked for the Honorable Chief Judge Mary M. Schroeder of the U.S. Court of Appeals for the Ninth Circuit. Cuéllar joined the Stanford Law School in 2001, and was promoted to Professor and Deane F Johnson Faculty Scholar in 2007. At Stanford, he also served as Co-Director of the university's inter-disciplinary Center for International Security and Cooperation from 2011 to 2013. In February 2013, he was chosen to serve as Director of the Freeman Spogli Institute for International Studies at Stanford University, a university-wide research and education institution.
From early 2009 to the summer of 2010, Cuéllar took leave from Stanford Law School and served as a Special Assistant to the President for Justice and Regulatory Policy at the White House Domestic Policy Council. While at the White House, he led the Domestic Policy Council’s work on public health and safety, regulatory reform, civil rights, immigration, and rural and agricultural policy. He coordinated the Food Safety Working Group, a new inter-agency effort tasked with revamping federal food safety efforts.
In July 2010, President Barack Obama appointed Cuéllar to the Council of the nonpartisan Administrative Conference of the United States. In addition, Education Secretary Arne Duncan appointed Cuéllar to the National Equity and Excellence Commission in early 2011. Cuéllar then served as Co-Chair of the Commission, which issued a unanimous report on February 19, 2013. He serves on the Board of Directors of The Constitution Project, a bipartisan non-profit organization that builds consensus on significant constitutional issues affecting the rule of law and criminal justice.
In 2011, Cuéllar was one of the candidates under consideration by California Governor Jerry Brown to fill the vacancy on the California Supreme Court created by the retirement of Justice Carlos R. Moreno.
In 2014, Governor Edmund G. Brown Jr. nominated Cuéllar for Associate Justice of the California Supreme Court. He was given the highest possible rating, "exceptionally well-qualified," by the California State Bar's independent Judicial Nominations Evaluation Commission.  On August 28, 2014, the California Commission on Judicial Appointments unanimously confirmed Cuéllar. 
Law Reform Work
Cuéllar was elected to the American Law Institute in 2008 and was elected to the ALI Council in 2014. He has worked on several ALI projects, including Model Penal Code: Sentencing, Principles of Government Ethics, and Restatement Fourth, The Foreign Relations Law of the United States.
