Two recent Supreme Court decisions seem to send conflicting messages about state and local laws regulating noncitizens. In one case, the justices upheld Arizona’s law imposing sanctions on employers who hire undocumented workers. But another ruling struck down a law that allowed for racial profiling of suspected illegal immigrants. UC Davis Law Professor Gabriel Chin sorts through the legal contradictions to find the right balance between state and federal governments. Chin is the featured speaker of the 2013 DeWitt Higgs Memorial Lecture, sponsored by Cal Western School of Law and UC San Diego.
