Failing to Answer Interrogatories in Philippine Courts: What Santiago Land Development Teaches Us

In litigation, discovery procedures like written interrogatories help parties obtain crucial information from each other before trial. But what happens when a party simply refuses to answer them? The Supreme Court case of Santiago Land Development Company v. Court of Appeals and Komatsu Industries (Phils.), Inc. (G.R. No. 103922, July 9, 1996) provides important guidance on this question—and clarifies why the remedy for such a failure is not always dismissal.

The Facts of the Case

The dispute began when Komatsu Industries failed to pay its debt of P27 million to the Philippine National Bank (PNB). PNB foreclosed on Komatsu's 18,000-square-meter property in Makati. Komatsu sued to stop the foreclosure, but the property was eventually sold to Santiago Land Development Company (SLDC) for P90 million.

After being allowed to intervene in the case, SLDC served written interrogatories on Komatsu's counsel on November 20, 1990. Komatsu never answered them. SLDC then moved to dismiss the case with prejudice under Section 5, Rule 29 of the Rules of Court, which allows a court to dismiss an action when a party wilfully fails to serve answers to interrogatories.

The trial court denied the motion to dismiss. SLDC elevated the matter to the Court of Appeals via certiorari, but that court also dismissed the petition—not because the motion to dismiss was wrongly denied, but because certiorari was not the proper remedy.

The Issue

The central question was whether the Court of Appeals committed grave abuse of discretion in refusing to order the dismissal of the civil case for Komatsu's failure to answer the interrogatories.

The Ruling

The Supreme Court upheld the Court of Appeals' decision. While the Court acknowledged that the trial court may have erred in denying the motion to dismiss, it stressed that mere error of judgment is not the same as grave abuse of discretion.

Under Section 5, Rule 29 of the Rules of Court, a court may dismiss an action or strike out pleadings when a party wilfully fails to answer interrogatories. However, the Court emphasized that this power is discretionary, not mandatory. The trial court is given leeway to decide whether dismissal is appropriate under the circumstances.

The Court also clarified an important procedural point: certiorari cannot be used to correct mere errors of procedure or mistakes in findings and conclusions. It is available only when a court acts with grave abuse of discretion amounting to lack or excess of jurisdiction. Since the denial of a motion to dismiss is an interlocutory order, it cannot be questioned through certiorari—it may only be raised on appeal after a final judgment.

Key Principles from the Decision

• Dismissal is discretionary. A court may dismiss a case for failure to answer interrogatories, but it is not required to do so. The rule says the court "may" strike out pleadings or dismiss the action, not that it "shall."
• Certiorari has limits. A party cannot use a petition for certiorari to challenge an interlocutory order denying a motion to dismiss, unless the court acted with grave abuse of discretion.
• Grave abuse of discretion is a high bar. It requires a capricious, arbitrary, and whimsical exercise of power—not simply an error in interpreting the rules.

Practical Takeaways

• Answer interrogatories promptly. Failure to do so can expose a party to sanctions, including dismissal of the case, striking out of pleadings, or default judgment.
• Dismissal is not automatic. Even if a party wilfully fails to answer, the court has discretion to impose a lesser sanction or deny dismissal altogether.
• Service on counsel is valid. Interrogatories may be properly served on a party's counsel of record, not necessarily on the party's officers directly.
• Know the right remedy. If a trial court denies a motion to dismiss, the aggrieved party cannot immediately seek certiorari. The proper course is to await final judgment and raise the issue on appeal.
• Act early in the case. In this case, the interrogatories were served after the party had already rested its case—a factor that influenced the court's view of the situation.
