Case dismissible if plaintiff not the real party in interest

Section 2, Rule 3 of the Rules of Court lays down the definition of a real party in interest as follows:
SEC. 2. Parties in interest. - A real party in interest is the party who stands to be benefited or injured by the judgment in the suit, or the party entitled to the avails of the suit. Unless otherwise provided by law or these Rules, every action must be prosecuted or defended in the name of the real party in interest.
The rule on real parties in interest has two (2) requirements, namely: (a) to institute an action, the plaintiff must be the real party in interest; and (b) the action must be prosecuted in the name of the real party in interest. Interest within the meaning of the Rules of Court means material interest or an interest in issue to be affected by the decree or judgment of the case, as distinguished from mere curiosity about the question involved. One having no material interest cannot invoke the jurisdiction of the court as the plaintiff in an action. When the plaintiff is not the real party in interest, the case is dismissible on the ground of lack of cause of action.[1] In Spouses Oco v. Limbaring,[2] the Supreme Court expounded on the purpose of this rule, to wit:
Necessarily, the purposes of this provision are 1) to prevent the prosecution of actions by persons without any right, title or interest in the case; 2) to require that the actual party entitled to legal relief be the one to prosecute the action; 3) to avoid multiplicity of suits; and 4) discourage litigation and keep it within certain bounds, pursuant to public policy.[3]
