SAN FRANCISCO — With Mariano-Florentino Cuéllar, Gov. Jerry Brown has placed another young, progressive academic on the California Supreme Court.

But though Cuéllar’s profile bears similarities with Brown’s 2011 court pick of Goodwin Liu, Cuéllar bears his own distinction as the court’s first justice to come out of modern Silicon Valley. He may not have the résumé of a tech executive, but the Palo Alto denizen swims in those waters as a professor at Stanford University whose passions and scholarship run as much toward policy and societal issues as pure legal pursuits.
