ยง 3001. Declaratory judgment. The supreme court may render a declaratory judgment having the effect of a final judgment as to the rights and other legal relations of the parties to a justiciable controversy whether or not further relief is or could be claimed. If the court declines to render such a judgment it shall state its grounds.
