Demurrer to Evidence in the Philippines: When Can a Criminal Case Be Dismissed for Insufficient Proof

The demurrer to evidence is a powerful tool for an accused person in a Philippine criminal case. It asks the court to dismiss the case after the prosecution rests, on the ground that the evidence presented is legally insufficient to prove guilt. When granted, the accused is acquitted, and the case ends. But when is a demurrer properly granted, and what happens if the trial court wrongly denies it? The Supreme Court's decision in Ong v. People (G.R. No. 140904, October 9, 2000) provides clear guidance.

The Facts of the Case

In 1993, Zeny Alfonso bought a paper bag-making machine from Solid Cement Corporation for P362,000.00. When she went to claim the machine, she discovered it had been mortgaged to another creditor who refused to release it. Alfonso refused the company's offer to return her money and instead filed a criminal complaint for estafa and other deceit.

At trial, the prosecution presented only Alfonso as its witness, along with several documentary exhibits. The defense objected to these documents, pointing out that they were mere photocopies with unauthenticated signatures. After the prosecution rested, the accused filed a demurrer to evidence, arguing the evidence was insufficient. The Metropolitan Trial Court (MeTC) denied the demurrer, ruling there was a prima facie case.

The Issue: What Remedy Lies After a Demurrer Is Denied?

The general rule is that an order denying a demurrer to evidence is interlocutory. It is not appealable, and certiorari does not ordinarily lie to challenge it. The accused should instead present evidence and, if convicted, appeal the conviction.

However, the Supreme Court in Ong recognized a critical exception: when the denial is tainted with grave abuse of discretion amounting to lack or excess of jurisdiction, certiorari is the proper remedy. This exception was previously acknowledged in Cruz v. People and Gutib v. Court of Appeals, both cited in the Ong decision.

The Ruling: Inadmissible Evidence Cannot Support a Demurrer

The Supreme Court found that the MeTC committed grave abuse of discretion in denying the demurrer. The prosecution's documentary evidence was inadmissible for two reasons.

First, the documents were private instruments. Under the Rules of Court, before a private document is received as authentic, its due execution and authenticity must be proved either by someone who saw it executed or by evidence of the genuineness of the maker's signature. The prosecution made no effort to authenticate the documents.

Second, the documents were mere photocopies—secondary evidence. Under the Rules of Court, secondary evidence is inadmissible unless the loss of the original is adequately proved. The prosecution failed to show any basis for admitting these copies.

With the documents excluded, the only remaining evidence was Alfonso's testimony. The Court noted that she had personal contact only with one of the accused, Ong, and only after the alleged sale was approved. Her testimony alone, unsupported by competent documentary evidence, was insufficient to prove the commission of the crime or the participation of all the accused.

Double Jeopardy Protects the Acquitted Accused

The Court also addressed the issue of double jeopardy. When the Regional Trial Court (RTC) granted the demurrer to evidence, that constituted a valid acquittal. A dismissal by grant of a demurrer to evidence is not appealable, because further prosecution would place the accused twice in jeopardy for the same offense. The Court of Appeals erred in reinstating the case.

Practical Takeaways

• A demurrer to evidence challenges the sufficiency of the prosecution's entire case. The court must determine whether there is competent evidence to sustain a conviction.
• The denial of a demurrer is generally not appealable and cannot be assailed by certiorari—but certiorari lies if the denial is attended by grave abuse of discretion.
• Private documents must be authenticated under the Rules of Court; photocopies require proof of loss of the originals before they can be admitted.
• When a demurrer is granted, the accused is acquitted, and the dismissal is final—the prosecution cannot appeal due to double jeopardy.
• An accused has the right to be protected from hasty, malicious, and oppressive prosecution, and the State has an interest in avoiding useless litigation.
