2. Garcetti v. Ceballos BACKGROUND: Los Angeles County Deputy District Attorney Richard Ceballos was concerned that a sheriff's deputy had lied in a search warrant affidavit. When his supervisors told him to keep quiet, he said he was legally obliged to tell the other side, and he testified for them in court. Consequently, he was demoted. He sued, arguing that his employer, the government, unfairly retaliated against him and violated his free speech rights.
