Ada vs. Baylon

Rescission under Article 1381(4) of the Civil Code is not preconditioned upon the final determination of the ownership of the thing subject of litigation, the primordial purpose of the provision being to secure the possible effectivity of the impending judgment by preventing the dissipation of the subject matter regardless of which contending claim is ultimately upheld.

Spouses Florentino and Maximina Baylon died survived by their legitimate children, including Rita Baylon and petitioner Lilia B. Ada. Following the subsequent deaths of some heirs, the surviving heirs disputed the possession and ownership of 43 parcels of land left by the Spouses Baylon, with Rita allegedly appropriating the estate's income to purchase two specific lots (Lot No. 4709 and half of Lot No. 4706).

• The Estate and the Heirs: Spouses Florentino and Maximina Baylon died, leaving 43 parcels of land. They were survived by legitimate children, including Rita Baylon and petitioner Lilia B. Ada. Some siblings predeceased, leaving their own heirs (e.g., Ramon left respondent Florante from a first marriage, and petitioner Flora and their children from a second marriage).
• The Partition Suit: Petitioners filed a complaint for partition, accounting, and damages against Florante, Rita, and Panfila. Petitioners alleged Rita possessed the 43 parcels and misappropriated the income to purchase Lot No. 4709 and half of Lot No. 4706. Defendants countered that only 22 parcels were co-owned, 10 were exclusively Rita's, and the remaining 11 were owned by other individuals; they claimed Rita purchased the disputed lots with her own money.
• The Donation Pendente Lite: During the pendency of the case, Rita executed a Deed of Donation conveying Lot No. 4709 and half of Lot No. 4706 to Florante. Rita died intestate and without issue shortly thereafter.
• The Supplemental Pleading: Upon learning of the donation, petitioners filed a Supplemental Pleading seeking rescission under Article 1381(4) of the Civil Code. They alleged Rita was very weak and executed the donation without their knowledge or court approval, thereby prejudicing their succession rights. Florante opposed, arguing Art. 1381(4) requires a prior judicial decree on ownership.

• Propriety of Rescission: Petitioners argued that the RTC aptly rescinded the donation inter vivos pursuant to Article 1381(4) of the Civil Code, as the conveyance was made pendente lite without their knowledge or court approval.
• Prematurity of Ownership Determination: Petitioners maintained that the CA erred in requiring a prior judicial determination of ownership as a precondition for rescission, asserting that such a ruling defeats the purpose of Article 1381(4).

• Precondition of Ownership: Respondent Florante asserted that an action for rescission is premature absent a prior favorable judicial ruling that the donated lots actually belonged to the estate of Spouses Baylon rather than exclusively to Rita.
• Validity of Donation: Respondent argued that if the lots were exclusively Rita's, she validly exercised her ownership right to dispose of them; consequently, the lots no longer formed part of Rita's estate upon her death and could not be included in the partition.

• Joinder of Causes of Action: Whether an action for partition (a special civil action) can be joined with an action for rescission (an ordinary civil action) in a single proceeding.
• Supplemental Pleading: Whether a new cause of action for rescission may be asserted through a supplemental pleading filed in an ongoing partition suit.
• Rescission Preconditions: Whether rescission under Article 1381(4) of the Civil Code is preconditioned upon a prior judicial determination of ownership of the thing under litigation.
• Necessity of Ownership Determination: Whether a determination of ownership of the donated lots is still necessary despite the rescission of the donation.

• Joinder of Causes of Action: A misjoinder of causes of action existed because partition is a special civil action while rescission is an ordinary civil action, and their variance in procedure precludes joinder. However, misjoinder is not a ground for dismissal and involves an implied admission of the court's jurisdiction. Because the RTC had jurisdiction over both actions and no party objected or moved for severance, the RTC validly adjudicated both.
• Supplemental Pleading: A supplemental pleading may raise a new cause of action provided it has some relation to the original cause of action. The rescission of the donation was germane to and intertwined with the partition case, as the lots were among the properties sought to be partitioned; the supplemental pleading merely amplified the original cause of action by praying for additional reliefs necessitated by events occurring after the filing of the complaint.
• Rescission Preconditions: Rescission under Article 1381(4) is not preconditioned upon the final determination of ownership. The provision's primordial purpose is to secure the possible effectivity of the impending judgment by preventing acts that would dissipate the subject matter or render the court's decision inutile. The concurrence of two requisites suffices: (1) the defendant enters into a contract referring to the thing subject of litigation during the pendency of the case; and (2) the contract was entered into without the knowledge and approval of the litigants or of competent judicial authority.
• Necessity of Ownership Determination: A definitive adjudication of ownership remains essential. The RTC's authority to direct partition in the proceedings extends only to properties belonging to the estate of Spouses Baylon. If the lots were exclusively Rita's, they cannot be partitioned simultaneously with the Spouses Baylon's estate in that specific proceeding, notwithstanding that the parties are also co-heirs of Rita.

• Rescission under Article 1381(4) of the Civil Code — Contracts which refer to things under litigation, entered into by the defendant without the knowledge and approval of the litigants or of competent judicial authority, are rescissible. The action requires: (1) the defendant, during the pendency of the case, enters into a contract referring to the thing subject of litigation; and (2) the contract was entered into without the knowledge and approval of the litigants or of a competent judicial authority. The right to rescind is not contingent upon the final determination of ownership, as the provision seeks to protect the binding effect of a court's impending adjudication vis-à-vis the thing subject of litigation regardless of which contending claim is subsequently upheld.
• Misjoinder of Causes of Action — The joinder of a special civil action and an ordinary civil action constitutes a misjoinder. However, misjoinder is not a ground for dismissal and involves an implied admission of the court's jurisdiction. If no objection is raised and the court does not motu proprio direct severance, the court may validly adjudicate the misjoined causes of action, provided it has jurisdiction over all of them.
• Supplemental Pleadings — A supplemental pleading may raise a new cause of action as long as it has some relation to the cause of action set forth in the original pleading. The fact that it technically states a new cause of action should not bar its allowance but is merely a matter for the court's discretion, applying a broad definition of "cause of action."

• "The right to ask for the rescission of a contract under Article 1381(4) of the Civil Code is not contingent upon the final determination of the ownership of the thing subject of litigation. The primordial purpose of Article 1381(4) of the Civil Code is to secure the possible effectivity of the impending judgment by a court with respect to the thing subject of litigation." — Defining the rationale for dispensing with the precondition of an ownership determination before rescission may be decreed.
• "A supplemental pleading may raise a new cause of action as long as it has some relation to the original cause of action set forth in the original complaint." — Clarifying the permissibility of asserting new causes of action via supplemental pleadings.

• Republic v. Herbieto, 498 Phil. 227 (2005) — Followed. Cited for the proposition that misjoinder of causes of action and parties does not involve a question of jurisdiction, is not a ground for dismissal, and constitutes an implied admission of the court's jurisdiction to order severance or adjudicate the claims.
• Planters Development Bank v. LZK Holdings and Development Corp., 496 Phil. 263 (2005) — Followed. Clarified that a supplemental pleading may state a new cause of action if related to the original, applying a broad definition of "cause of action," thereby modifying the stricter rule previously laid down in Leobrera v. Court of Appeals.
• Young v. Spouses Sy, 534 Phil. 246 (2006) — Followed. Elucidated the purpose of a supplemental pleading as bolstering the primary pleading by setting up new facts that justify, enlarge, or change the relief with respect to the same subject matter.

• Article 1381(4), Civil Code of the Philippines — Declares rescissible those contracts which refer to things under litigation if they have been entered into by the defendant without the knowledge and approval of the litigants or of competent judicial authority. Applied to rescind the donation inter vivos executed by Rita Baylon pendente lite, as the conveyance of the disputed lots was made without the knowledge or approval of the petitioners or the trial court.
• Section 6, Rule 10, Rules of Court — Governs supplemental pleadings, allowing a party to set forth transactions, occurrences, or events which have happened since the date of the pleading sought to be supplemented. Applied to permit the assertion of a new cause of action for rescission arising from the donation executed during the pendency of the case.
• Section 5, Rule 2, Rules of Court — Provides that joinder of causes of action shall not include special civil actions governed by special rules. Applied to identify the procedural misjoinder of partition (special civil action) and rescission (ordinary civil action).
