Election Protests Understanding Demurrer to Evidence and Waiver of Rights in Philippine Law

The Supreme Court case of Tan v. Court of Appeals (G.R. No. 110715, December 12, 1997) clarifies a critical rule in Philippine criminal procedure: when an accused files a demurrer to evidence without express leave of court, they waive the right to present their own evidence. This decision is essential for anyone facing criminal charges, as it underscores the strategic importance of understanding the consequences of a demurrer before filing one.

The Facts of the Case

In December 1986, Mariano Macias saw an advertisement for Isuzu trucks and contacted the seller, Elbert Tan. Tan claimed ownership of the trucks and agreed to sell one to Macias for P92,000, with a down payment of P17,000 and Macias's school bus valued at P65,000 as trade-in. Macias paid the down payment and transferred the bus to Tan.

Later, Macias discovered that Tan did not actually own the trucks. Despite promises to deliver the vehicle, Tan failed to do so and avoided Macias. During the preliminary investigation, Tan paid P22,000 and entered a compromise agreement to return P45,000 for the school bus. However, Tan failed to comply with the agreement, leading to the filing of an estafa charge under Article 315 of the Revised Penal Code.

The Procedural Issue: Demurrer to Evidence

After the prosecution rested its case, Tan filed a motion for leave to file a demurrer to evidence. The trial court denied the motion but explicitly warned Tan that filing a demurrer would constitute a waiver of his right to present evidence. Despite this warning, Tan filed his demurrer, which the court denied.

The trial court then considered the case submitted for decision based solely on the prosecution's evidence, since Tan had waived his right to present his defense. Tan was convicted of estafa, and the Court of Appeals affirmed the conviction.

The Supreme Court's Ruling

The Supreme Court denied Tan's petition, affirming the lower courts' decisions. The Court addressed two main issues: whether Tan could present evidence after his demurrer was denied, and whether novation or compromise could extinguish criminal liability for estafa.

Waiver of Right to Present Evidence

The Court ruled that under Section 15, Rule 119 of the Rules of Court, as amended in 1988, an accused who files a demurrer to evidence without express leave of court waives the right to present evidence. The amended rule provides that if the court denies the motion to dismiss, the accused may adduce evidence in defense—but only when the demurrer was filed with prior express leave of court.

The Court emphasized that Tan had been unequivocally warned by the trial court about this consequence. The trial court's order could not be interpreted as an implied grant of leave, because the rules require express leave for the accused to retain the right to present evidence after a denied demurrer.

The Court distinguished this case from Oñas v. Sandiganbayan, where the accused had included a reservation in her demurrer that it was "without prejudice to her right to adduce evidence." Tan's demurrer contained no such reservation.

Novation Cannot Extinguish Criminal Liability

The Court also rejected Tan's argument that the compromise agreement constituted novation that extinguished his criminal liability. Citing Article 89 of the Revised Penal Code, the Court noted that novation is not among the grounds for extinction of criminal liability. Criminal offenses are committed against the People, and the offended party cannot waive or extinguish the criminal liability imposed by law.

The Court held that the elements of estafa were established: Tan defrauded Macias through deceit by falsely claiming ownership of the truck, and Macias suffered damage by delivering the down payment and school bus. The compromise agreement and partial payment only reduced the civil liability, not the criminal liability.

Practical Takeaways

• Understand the consequences: Filing a demurrer to evidence without express leave of court means waiving the right to present defense evidence. This is a high-stakes decision that should not be made lightly.
• Seek express leave: If an accused wishes to preserve the right to present evidence after a denied demurrer, they must obtain express leave of court before filing the demurrer.
• Include a reservation: As demonstrated in Oñas, including a reservation in the demurrer that it is "without prejudice to the right to adduce evidence" may help preserve that right.
• Compromise does not erase criminal liability: Settling with the complainant or entering a compromise agreement does not extinguish criminal liability for estafa. It may affect civil liability but not the criminal case.
• Consult a lawyer early: Given the procedural complexities and severe consequences, anyone facing criminal charges should seek legal counsel before deciding whether to file a demurrer to evidence.
