The Supreme Court clarified the application of res judicata in mortgage foreclosure cases, emphasizing that a prior court decision, even if based on a motion to dismiss, can bar subsequent actions involving the same core issues. This ruling prevents parties from repeatedly relitigating matters already decided, promoting judicial efficiency and protecting the finality of judgments. However, the Court also affirmed the right of mortgagors to recover excess proceeds from a foreclosure sale, ensuring fairness and preventing unjust enrichment by the mortgagee.

Foreclosure Fights: When Does a Dismissed Case Prevent a Second Chance?

This case revolves around a loan obtained by Feliciano Conquilla and his children from Luzon Development Bank, secured by a mortgage on properties owned by the Conquillas. After the Conquillas defaulted on their loan payments, the bank initiated foreclosure proceedings. In response, the Conquillas filed multiple lawsuits to prevent the foreclosure, ultimately leading to the present case where they sought to nullify the foreclosure and recover alleged loan balances and excess proceeds from the sale.

The central legal question is whether the dismissal of a prior case filed by the Conquillas to enjoin the foreclosure (Civil Case No. N-6659) bars the present action under the principle of res judicata. The petitioner bank argued that the prior dismissal, even without a full trial, constituted a judgment on the merits, precluding the Conquillas from relitigating the same issues. The respondents, on the other hand, contended that the prior dismissal was not a judgment on the merits and that the present case involved different causes of action.

Res judicata, also known as claim preclusion, prevents parties from relitigating a cause of action that has already been decided by a court of competent jurisdiction. As the Supreme Court reiterated, the doctrine of res judicata has the following elements, all of which must concur: (1) the former judgment is final; (2) it is rendered by a court having jurisdiction over the subject matter and the parties; (3) it is a judgment or an order on the merits; (4) there is — between the first and the second actions — identity of parties, of subject matter, and of causes of action. Allied Banking Corporation v. CA, 229 SCRA 252, 258, January 10, 1994.

A key point of contention was whether the dismissal of the prior case was a judgment “on the merits.” The Court of Appeals (CA) held that it was not because no trial had been conducted. However, the Supreme Court disagreed, explaining that a judgment can be considered “on the merits” even if it is based on a motion to dismiss, particularly when the dismissal involves a legal declaration of the parties’ rights and duties based on the facts disclosed in the pleadings.

In this instance, the Court emphasized that the prior dismissal was based on the Conquillas’ own admission in their complaint that they had defaulted on their loan payments, triggering the acceleration clause in the mortgage contract. An acceleration clause is a stipulation stating that, on the occasion of the mortgagors’ default, the whole sum remaining unpaid automatically becomes due and payable. The Court reasoned that this admission justified the bank’s foreclosure and rendered a full trial unnecessary.

The Court likened the situation to a judgment on the pleadings, where a court can render a decision based solely on the pleadings if there are no genuine issues of material fact. Although no motion for a judgment on the pleadings was filed by respondents, the trial court — on the authority akin to that granted by Rule 18 Section  2(g) –decided motu proprio to render a judgment on the pleadings. The Court further cited previous cases, such as Manalo v. CA and Mendiola v. CA, to support the principle that a dismissal for failure to state a cause of action can operate as res judicata if the order of dismissal actually ruled on the issues raised.

Turning to the issue of identity of parties, the Court acknowledged that the prior case was filed in the name of Columbia College, Inc., while the present case was filed by the Conquillas in their individual capacities. However, the Court found that there was substantial identity of parties, as the Conquillas were the registered owners of the mortgaged properties and had a community of interest with Columbia College, Inc.

It is axiomatic that to invoke res judicata, absolute identity of parties is not required. A substantial identity of parties is sufficient. There is substantial identity of parties when there is a community of interest between a party in the first case and that in the second one, even if the latter party was not impleaded in the first case.

Finally, the Court addressed the requirement of identity of causes of action. While the Conquillas argued that the prior case sought to prevent foreclosure while the present case sought to nullify it, the Court held that the underlying cause of action—the alleged prematurity of the foreclosure—was the same. The test to determine whether the causes of action are identical is to ascertain whether the same evidence will sustain both actions, or whether there is an identity in the facts essential to the maintenance of the two actions.  If the same facts or evidence would sustain both, the two actions are considered the same, and a judgment in the first case is a bar to the subsequent action.

However, the Court carved out an exception regarding the Conquillas’ claim for the excess proceeds from the foreclosure sale. The Court reasoned that this cause of action was distinct from the issue of the validity of the foreclosure and could not have been raised in the prior case. Therefore, the Court remanded the case to the trial court for determination of whether the foreclosure sale yielded proceeds exceeding the amount of the loan, interest, and costs.

The Court stated that, according to the principle of mortgage, the mortgagee has the right to foreclose the mortgaged property only to the extent of the loan secured by it.  Any decision to the contrary abets unjust enrichment. Furthermore, the Court explicitly stated that the lower court should no longer inquire into the validity of the mortgage loan and the right to foreclose as these had reached finality in the prior case.
