William J. Brennan, Jr., Perez v. Ledesma — Dissent
“ It often happens that courts are unwilling to grant injunctions to restrain the enforcement of penal statutes or ordinances, and relegate the plaintiff to his option, either to violate the statute and take his chances in testing constitutionality on a criminal prosecution, or else to forego, in the fear of prosecution, the exercise of his claimed rights. Into this dilemma no civilized legal system operating under a constitution should force any person. ”
