In a special action brought in the Superior Court, the judgment shall be in the form of a judgment for any civil action, with no special requirements heretofore peculiar to writs; the grounds of the decision shall be stated in the judgment. The judgment may grant to the plaintiff part or all of the relief requested, or may dismiss the action either on the merits or without prejudice. If the action was brought to review a determination or order of a body or officer, the judgment may annul or confirm the determination in whole or in part, or modify it, and may direct, order, or prohibit specified action by the defendant.
