Atty. Manuel F. Concepcion vs. Atty. Jesus V. Agana and Hon. Judge Erasto Salcedo RTC Branch 31, Tagum, Davao del Norte (Atty. Salcedo), ADM. NO. RTJ-96-217, February 17, 1997

nn

Imagine being dragged back into court for the same dispute you thought was long resolved. The legal principle of res judicata protects individuals and the court system from such repetitive and wasteful litigation. It ensures finality in legal judgments, preventing parties from re-litigating issues that have already been decided by a competent court.

nn

This case, Atty. Manuel F. Concepcion vs. Atty. Jesus V. Agana and Hon. Judge Erasto Salcedo, revolves around the application of res judicata. The Supreme Court dismissed a complaint against a judge because the same allegations had already been dismissed in a prior case. This decision underscores the importance of res judicata in maintaining judicial efficiency and protecting individuals from harassment through repeated lawsuits.

What is Res Judicata?

nn

Res judicata, Latin for “a matter judged,” is a fundamental principle of civil law that prevents the re-litigation of issues that have already been decided in a prior case. It aims to promote judicial efficiency, prevent harassment of parties, and ensure the stability of judgments. This doctrine is enshrined in the Rules of Court and numerous Supreme Court decisions.

nn

There are two aspects to res judicata: bar by prior judgment and conclusiveness of judgment. This case focuses on “bar by prior judgment,” which applies when a second case involves the same parties, subject matter, and cause of action as the first case. If these three identities exist, the judgment in the first case serves as an absolute bar to the second case.

nn

Consider this scenario: A homeowner sues a contractor for breach of contract due to shoddy workmanship. The court rules in favor of the contractor. Later, the homeowner files another lawsuit against the same contractor, alleging the same defects and seeking the same damages. Res judicata would prevent this second lawsuit because the matter has already been decided.

nn

The elements of res judicata are clearly outlined in Philippine jurisprudence. In the case of Nabus v. Court of Appeals (193 SCRA 732, 739 [1991]), the Supreme Court defined it as follows:

nn

“xxx (T)here is ‘bar by former judgment’ when, between the first case where the judgment was rendered, and the second case where such judgment is invoked, there is identity of parties, subject matter and cause of action. When the three identities are present, the judgment on the merits rendered in the first constitutes an absolute bar to the subsequent action. It is final as to the claim or demand in controversy, including the parties and those in privity with them, not only as to every matter which was offered and received to sustain or defeat the claim or demand, but as to any other admissible matter which might have been offered for that purpose xxx”

The Story of the Case: Concepcion vs. Agana and Salcedo

nn

The case began with a complaint filed against Judge Erasto Salcedo, alleging dishonest and deceitful conduct when he was a practicing lawyer. The complainant, Atty. Manuel F. Concepcion, claimed that Judge Salcedo, along with Atty. Jesus V. Agana, conspired to cancel a notice of lis pendens to the detriment of Atty. Concepcion’s clients.

nn

The Office of the Court Administrator (OCA) investigated the complaint and discovered that it was essentially a rehash of a previous disbarment case (A.M. No. RTJ-95-1312) that the Supreme Court had already dismissed for lack of merit. This earlier case involved the same allegations against Atty. Agana and then-Atty. Salcedo, who had since become a judge.

nn

The Supreme Court, in its decision, emphasized the principle of “bar by former judgment” and dismissed the complaint. The Court noted the striking similarities between the current complaint and the previously dismissed case, highlighting the identity of parties, subject matter, and causes of action.

Here’s a breakdown of the key events:

nn

n
• Prior Case (A.M. No. RTJ-95-1312): A disbarment complaint was filed against Atty. Agana and Atty. Salcedo (then a lawyer) based on allegations of misconduct related to the cancellation of a notice of lis pendens. The Supreme Court dismissed this case for lack of merit.

n

• Current Case (ADM. NO. RTJ-96-217): Atty. Concepcion filed a complaint seeking the dismissal of Judge Salcedo (formerly Atty. Salcedo) based on the same allegations of misconduct.

n

• Supreme Court Decision: The Court dismissed the complaint, invoking the principle of res judicata, specifically
