Read this passage: A stand-up comedian is accused of violating a new state
law that makes it illegal to insult someone based on his or
her gender, race, or religion. He is ordered to pay a steep
fine and told that he cannot appeal the penalty. The
comedian's lawyer claims that this is unfair, as the law had
not been widely publicized. She also argues that denying
defendants the right to appeal is a violation of state law.
What principle is the lawyer relying on to defend her client?
