A court decision in a civil case that tells the parties what their rights and responsibilities are, without awarding damages or ordering them to do anything. Unlike most court cases, where the plaintiff asks for damages or other court orders, the plaintiff in a declaratory judgment case simply wants the court to resolve an uncertainty so that it can avoid serious legal trouble in the future. Courts are usually reluctant to hear declaratory judgment cases, preferring to wait until there has been a measurable loss. But especially in cases involving important constitutional rights, courts will step in to clarify the legal landscape. For example, many cities regulate the right to assemble by requiring permits to hold a parade. A disappointed applicant who thinks the decision-making process is unconstitutional might hold his parade anyway and challenge the ordinance after he’s cited; or he might ask a court beforehand to rule on the constitutionality of the law. By going to court, the applicant may avoid a messy confrontation with the city -- and perhaps a citation, as well.
