Justice Mariano-Florentino (Tino) Cuéllar began serving on the California Supreme Court in January 2015. Previously he was the Stanley Morrison Professor of Law, Professor (by courtesy) of Political Science, and Director of the Freeman Spogli Institute for International Studies at Stanford University. A fellow of the American Academy of Arts and Sciences, Cuéllar is a scholar of public law, complex organizations, and political economy whose work explores how change happens in administrative agencies and legislation, cyberlaw, public health and safety, and international affairs. At the Freeman Spogli Institute, he grew the faculty, launched initiatives on global poverty and cyber policy to support creation of new university research centers, and expanded the Institute’s work on public health, climate policy, nuclear security, and education. In the Obama administration he led the White House Domestic Policy Council’s teams working on civil and criminal justice, public health, and immigration (2009-2010). In this capacity, he was responsible for efforts to enact bipartisan food safety, public health, and sentencing reform legislation, as well as the repeal of the military’s Don’tAsk/Don’t Tell policy. He then co-chaired the U.S. Department of Education’s Equity and Excellence Commission (2011-2013), which delivered a unanimous report to Congress offering a roadmap for reforms enacted in the Every Student Succeeds Act. Currently, he chairs the boards of the Center for Advanced Study in the Behavioral Sciences, AI Now, and Stanford Seed, and serves on the Harvard Corporation (President & Fellows of Harvard College), the board of Hewlett Foundation, and the council of the American Law Institute. After joining the Supreme Court, he led the judiciary’s implementation task force on language access to expand services for the millions of Californians who are limited-English speakers (2015-2019). A naturalized U.S. citizen born in northern Mexico, he is a graduate of Harvard, Stanford, and Yale Law School, and clerked for the Chief Judge of the U.S. Court of Appeals for the Ninth Circuit.
