The Limits of Appellate Courts Introducing New Evidence on Appeal in Philippine Law

The rule that appellate courts do not receive new evidence is a cornerstone of Philippine remedial law. When a case reaches the Court of Appeals or the Supreme Court, the review is confined to the record of the trial court. The parties cannot introduce new witnesses, documents, or other evidence that were not presented during the trial. This principle ensures orderliness in litigation and respects the trial court's unique role in receiving and weighing evidence. A recent decision of the Supreme Court, People v. Tamaño (G.R. No. 208643, December 5, 2016), illustrates how this rule operates in practice, particularly in criminal cases involving the Comprehensive Dangerous Drugs Act.

The Case Before the Court

Susan M. Tamaño and Jaffy B. Gulmatico were charged with illegal sale, illegal possession, and possession of drug paraphernalia under Republic Act No. 9165. The prosecution presented its case through the testimony of police officers who conducted a buy-bust operation. The defense offered a different version of events, claiming that the drugs were planted and that the accused were merely carrying a bag for a friend.

The Regional Trial Court convicted the accused, and the Court of Appeals affirmed the conviction. On further appeal to the Supreme Court, the accused raised several issues, including alleged contradictions in the prosecution witnesses' testimony, the timing of the recording of the buy-bust money, the absence of an inventory at the place of arrest, and the sufficiency of compliance with the chain of custody rule under Section 21 of R.A. No. 9165.

The Rule on New Evidence on Appeal

The Supreme Court emphasized that the accused were essentially raising questions about the validity of the buy-bust operation and the chain of custody. However, these issues were based on the evidence already presented during trial. The Court noted that the accused could not raise new arguments or present new evidence for the first time on appeal.

The Court quoted the rule from Mallillin v. People (G.R. No. 172953, April 30, 2008) on how the chain of custody should be established. The rule requires testimony about every link in the chain, from the moment the item was picked up to the time it is offered into evidence. Each person who touched the exhibit must describe how and from whom it was received, where it was, and what happened to it while in their possession.

Substantial Compliance with Section 21

The Court addressed the accused's argument that the police failed to strictly comply with Section 21 of R.A. No. 9165, which requires an immediate physical inventory and photographing of seized drugs in the presence of the accused, a media representative, a DOJ representative, and an elected public official.

The Court ruled that non-compliance with these requirements does not automatically render the arrest illegal or the seized items inadmissible. What matters is whether the integrity and evidentiary value of the seized items were preserved. The Court found that the prosecution established every link in the chain of custody, from the moment the items were seized to their presentation in court. The marking, handling, and laboratory examination were all properly testified to by the police officers and the forensic chemist.

The Court also noted that the accused failed to specifically challenge the custody and safekeeping of the drugs before the trial court. They could not question the alleged non-compliance with Section 21 for the first time on appeal.

The Court's Ruling

The Supreme Court sustained the conviction. The Court found that the elements of illegal sale, illegal possession, and possession of drug paraphernalia were all proven beyond reasonable doubt. The accused's defense of denial and frame-up could not prevail over the positive and categorical testimony of the police officers.

The Court modified only the penalty in one case, adjusting the indeterminate sentence for illegal possession of dangerous drugs. The rest of the penalties were affirmed.

Practical Takeaways

• Appellate review is limited to the record. Parties cannot introduce new evidence on appeal. If a factual issue was not raised during trial, it generally cannot be raised for the first time on appeal.
• The chain of custody rule is critical in drug cases. The prosecution must show by records or testimony the continuous whereabouts of the seized drugs from seizure to presentation in court.
• Substantial compliance may suffice. Failure to strictly comply with Section 21 of R.A. No. 9165 does not automatically invalidate the seizure, as long as the integrity and evidentiary value of the seized items are preserved.
• Raise issues at the trial court level. A party who fails to challenge the admissibility or custody of evidence during trial may be barred from doing so on appeal.
• The presumption of regularity applies. Law enforcement agencies are presumed to have performed their duties regularly, and this presumption can only be overcome by clear and convincing evidence.
