Section 6. Misjoinder of causes of action. — Misjoinder of causes of action is not a ground for dismissal of an action. A misjoined cause of action may, on motion of a party or on the initiative of the court, be severed and proceeded with separately. (Rule 2, Rules of Court)

Is misjoinder of causes of action a ground for dismissal of an action? What is the remedy for misjoinder?

Misjoinder of causes of action is not a ground for dismissal of an action. A misjoined cause of action may, on motion of a party or on the initiative of the court, be severed and proceeded with separately.

For example, if an action for forcible entry is joined in one complaint with the causes of actions based on several promissory notes, the complaint should not be dismissed based on the misjoinder of the forcible entry case. Instead, the cause of action predicated on forcible entry may be severed from the complaint upon motion of a party or by the court motu proprio.


If there is no objection to the improper joinder or the court did not motu proprio direct a severance, may the court adjudicate the misjoined cause of action?

●  Yes, provided that the court trying the case has jurisdiction over all of the causes of action therein.

● Misjoinder of causes of action is not a ground for dismissal. Indeed, the courts have the power, acting upon the motion of a party to the case or sua sponte, to order the severance of the misjoined cause of action to be proceeded with separately. However, if there is no objection to the improper joinder or the court did not motu proprio direct a severance, then there exists no bar in the simultaneous adjudication of all the erroneously joined causes of action. On this score, our disquisition in Republic of the Philippines v. Herbieto is instructive, viz:
This Court, however, disagrees with petitioner Republic in this regard. This procedural lapse committed by the respondents should not affect the jurisdiction of the MTC to proceed with and hear their application for registration of the Subject Lots.

Considering every application for land registration filed in strict accordance with the Property Registration Decree as a single cause of action, then the defect in the joint application for registration filed by the respondents with the MTC constitutes a misjoinder of causes of action and parties. Instead of a single or joint application for registration, respondents Jeremias and David, more appropriately, should have filed separate applications for registration of Lots No. 8422 and 8423, respectively.

Misjoinder of causes of action and parties do not involve a question of jurisdiction of the court to hear and proceed with the case. They are not even accepted grounds for dismissal thereof. Instead, under the Rules of Court, the misjoinder of causes of action and parties involve an implied admission of the court’s jurisdiction. It acknowledges the power of the court, acting upon the motion of a party to the case or on its own initiative, to order the severance of the misjoined cause of action, to be proceeded with separately (in case of misjoinder of causes of action); and/or the dropping of a party and the severance of any claim against said misjoined party, also to be proceeded with separately (in case of misjoinder of parties).
It should be emphasized that the foregoing rule only applies if the court trying the case has jurisdiction over all of the causes of action therein notwithstanding the misjoinder of the same. If the court trying the case has no jurisdiction over a misjoined cause of action, then such misjoined cause of action has to be severed from the other causes of action, and if not so severed, any adjudication rendered by the court with respect to the same would be a nullity.

Here, Florante posed no objection, and neither did the RTC direct the severance of the petitioners’ action for rescission from their action for partition. While this may be a patent omission on the part of the RTC, this does not constitute a ground to assail the validity and correctness of its decision. The RTC validly adjudicated the issues raised in the actions for partition and rescission filed by the petitioners. (Ada vs. Baylon, G.R. No. 182435, August 13, 2012)


Actions which could not be joined:

1. Partition and Recission of Donation

● The action for partition filed by the petitioners could not be joined with the action for the rescission of the said donation inter vivos in favor of Florante. Lest it be overlooked, an action for partition is a special civil action governed by Rule 69 of the Rules of Court while an action for rescission is an ordinary civil action governed by the ordinary rules of civil procedure. The variance in the procedure in the special civil action of partition and in the ordinary civil action of rescission precludes their joinder in one complaint or their being tried in a single proceeding to avoid confusion in determining what rules shall govern the conduct of the proceedings as well as in the determination of the presence of requisite elements of each particular cause of action. (Ada vs. Baylon)
