PRINCIPLE STATEMENT

The jurisdiction of the court to make a declaration is not confined to cases where a plaintiff has a complete and subsisting cause of action but may also be employed in all cases where the plaintiff conceives they have a right; it is the person who is seeking relief on whom a right to relief is alleged to exist, whose application to the court is not to be defeated because they apply merely for a declaratory judgment or order, and whose application for a declaration of their right is not to be refused merely because they cannot establish a legal cause of action.

EXPLANATION / SCOPE

Declaratory relief jurisdiction is broader than complete cause of action cases. Scope: Courts can grant declarations: where plaintiff has complete cause of action, AND where plaintiff conceives they have right (even without complete cause of action). Key principle: Plaintiff seeking declaration shouldn’t be defeated because: (1) they seek only declaratory relief (not coercive relief); (2) they cannot establish traditional legal cause of action. This serves: recognizing declarations as distinct remedy, providing access to justice for rights declaration, and not confining declarations to complete causes of action. “Conceives he has a right” means: believes right exists, asserts entitlement, and seeks judicial confirmation—even if traditional cause of action elements incomplete. Important qualification: This doesn’t mean any conceived right warrants declaration—court must recognize the alleged right and be prepared to give it legal consequence (see Principle 574). But threshold is lower than complete cause of action: plaintiff can seek declaration where: right is alleged/conceived, judicial clarification needed, and dispute exists about right—even without all elements of traditional cause of action. This reflects: declaratory relief’s preventive/clarifying nature, broader availability than coercive remedies, and recognition that rights disputes need resolution before traditional causes of action fully mature. Courts have jurisdiction to declare rights in broader circumstances than awarding damages or specific performance
