G.R. No. L-30978 - Medina vs. Yan

Case Summary (G.R. No. L-30978)

Factual Background

Petitioners were military personnel assigned as the security detail for Senator Benigno Aquino, Jr. upon his return to Manila on August 21, 1983. Senator Aquino was fatally shot as he descended from the China Airlines aircraft at Manila International Airport, and Rolando Galman was also killed on the airport tarmac. The petitioners were indicted jointly with other military personnel for the double homicides. At the first Sandiganbayan trial the accused were acquitted; this Court later found that trial a sham and ordered a re-trial.

Trial and Conviction on Re-trial

On re-trial before the Sandiganbayan, the court acquitted certain accused but found the petitioners guilty as principals of murder in Criminal Cases Nos. 10010 and 10011. The Sandiganbayan sentenced each petitioner to reclusion perpetua in both cases. The Sandiganbayan’s decision of September 28, 1990, and its November 15, 1990 resolution denying reconsideration, exhaustively analyzed the forensic and testimonial evidence, concluding that the fatal bullet’s trajectory was forward, downward and medially and that the fatal shot was consistent with being fired from an elevation higher than the point of entry, thereby supporting testimony that a military escort, C1C Rogelio Moreno, fired the fatal shot on the bridge stairs.

Exhaustion of Remedies and Finality

Petitioners sought relief by petition for review to this Court and by motion for reconsideration. This Court denied the petition for review in a resolution dated July 25, 1991, upholding the Sandiganbayan’s factual findings and credibility assessments, and the judgment became final and executory thereafter, with formal entry of judgment on September 30, 1991.

Petitioners’ Motion to Re-Open and Grounds Asserted

In August 2004 petitioners secured assistance from the Chief Public Attorney and presented to the Court a motion to re-open the cases and order a third trial. They advanced three principal grounds: (1) newly discovered evidence in the form of an independent forensic review that allegedly exposed false forensic claims underlying their conviction and the availability of a key defense eyewitness; (2) grave violations of due process, including insufficient legal assistance, deprivation of counsel of choice, duress of defense witnesses, suppression of evidence, and use of false forensic evidence; and (3) serious misapprehension of facts by the Sandiganbayan based on false forensic evidence.

The Forensic Review and Proffered Evidence

Petitioners sought to present the findings of an Independent Forensic Group from the University of the Philippines comprising a forensic anthropologist, medico-legal practitioner, forensic consultant, and forensic dentistry consultant. The group’s report concluded that the physical evidence did not support the Sandiganbayan’s finding that C1C Moreno fired at Senator Aquino on the stairway, and posited that Senator Aquino was shot while walking on the tarmac toward the AVSECOM van. The report detailed extensive materials and methods, including reliance on court records, photographs, autopsy reports, recovered firearms and ammunition, witness statements, reenactments, ocular inspections, ballistic experiments, X-rays, and comparisons with forensic literature.

Alleged Eyewitness Statement

Petitioners also offered an affidavit of SPO4 Ruben M. Cantimbuhan, the driver of the AVSECOM van, who asserted that he saw a man in a blue uniform, later identified as Rolando Galman, fire at Senator Aquino on the tarmac as the senator was about to board the van. Petitioners characterized this testimony as a key defense eyewitness account that would materially alter the evidentiary picture.

Legal Standard for New Trial under Rule 121

The Court examined Rule 121, particularly Sections 1, 2 and 6, which permit a court to grant a new trial before a conviction becomes final, on grounds of trial errors prejudicial to the accused or newly discovered material evidence that could not, with reasonable diligence, have been discovered and produced at trial and which would probably change the judgment. The Court reiterated the established requisites for newly discovered evidence under the Berry rule: the evidence must have been discovered after trial; could not have been discovered with reasonable diligence before or during trial; be material and not merely cumulative, corroborative, or impeaching; and be of such weight that it would probably change the judgment.

Court’s Analysis of Temporal and Diligence Aspects

The Court found that petitioners failed to meet the threshold requirement that the proffered forensic analysis and the purported eyewitness account were truly newly discovered or could not have been obtained with reasonable diligence. The forensic group’s report relied principally on the same physical exhibits, autopsy reports, photographs, testimonial records, and scene measurements that were already part of the record at the time of trial. The Court emphasized that the materials and methods listed by the forensic group were available to the defense during the re-trial and that petitioners could have sought independent expert opinions prior to submission of the case.

Assessment of Materiality and Probative Weight

The Court concluded that the forensic report essentially reiterated the defense theory already advanced at trial rather than presenting new materials unavailable to the defense. The Court held that the proffered evidence was largely cumulative or impeaching and that it would not probably have produced a different judgment when measured against the testimonial and physical evidence the Sandiganbayan had accepted. The Sandiganbayan’s detailed factual findings on trajectory, autopsy interpretation, ocular inspections, and eyewitness credibility were affirmed by this Court on prior review and remained controlling absent the stringent showing required for a new trial.

Evaluation of the Alleged New Eyewitness

SPO4 Cantimbuhan’s affidavit was characterized by the Court as corroborative of accounts already presented by defense witnesses who testified that Senator Aquino was on the tarmac when shot. The Sandiganbayan had expressly discredited those accounts in favor of prosecution eyewitnesses such as Rebecca Quijano and Jessie Barcelona, whose testimonies the trial court found consistent with the downward trajectory and other physical facts. The Court held that Cantimbuhan’s statement, being cumulative, would not have altered the evaluation of credibility or the ultimate judgment.

Claims of Denial of Due Process and Ineffective Assistance

The Court addressed petitioners’ assertions of inadequate legal assistance and deprivation of counsel of choice. It found these claims unsubstantiated. The records showed that Atty. Rodolfo U. Jimenez ably represented petitioners at trial and on appeal, presented

Case Syllabus (G.R. No. L-30978)

Parties and Posture

petitioners were military personnel who served as the security detail of Senator Benigno Aquino, Jr., and were convicted by the Sandiganbayan in Criminal Cases Nos. 10010 and 10011 for the double murder of Senator Aquino and Rolando Galman.
The Sandiganbayan initially rendered an acquittal on December 2, 1985, which this Court later nullified in Galman vs. Sandiganbayan, 144 SCRA 43 (1986), as a sham trial and ordered a re-trial.
On September 28, 1990, the Sandiganbayan convicted the petitioners as principals and sentenced them to reclusion perpetua in each case.
The petitioners' petition for review and motion for reconsideration in this Court were denied, after which the judgment became final and entry of judgment was made on September 30, 1991.
In August 2004 the petitioners filed a Motion To Re-Open Case With Leave Of Court seeking a re-trial based on alleged newly discovered evidence and due process violations, with assistance sought from the Chief Public Attorney and the Independent Forensic Group of the University of the Philippines.

Facts

Senator Benigno Aquino, Jr. was fatally shot as he descended from a China Airlines aircraft at the Manila International Airport on August 21, 1983, and Rolando Galman was also killed at the tarmac.
The prosecution theory at retrial was that C1C Rogelio B. Moreno, a military escort positioned behind the Senator on the bridge stairs, fired the fatal shot.
The Sandiganbayan found the fatal bullet's trajectory to be forward, downward, and medially, and concluded that the shooter stood at a higher elevation than the wound of entry.
Several prosecution eyewitnesses, including Rebecca Quijano and Jessie Barcelona, testified that the Senator was shot on the bridge stairs and their testimony was found credible by the Sandiganbayan.
The defense maintained that the Senator was shot on the tarmac while walking to an AVSECOM van and that Rolando Galman was the shooter, a theory supported at the motion stage by an affidavit of SPO4 Ruben M. Cantimbuhan.

Motion

The petitioners moved to re-open the cases and sought a third trial on grounds of newly discovered forensic evidence, an alleged key eyewitness, and multiple due process violations.
The petitioners specifically prayed that this Court annul its resolutions dated July 23, 1991 and September 10, 1991, annul the Sandiganbayan decision dated September 28, 1990, and order re-opening or re-trial before the Sandiganbayan.

Governing Rule

Rule 121 of the 2000 Rules of Criminal Procedure authorizes a court to grant a new trial at any time before a judgment of conviction becomes final, and prescribes grounds for new trial including errors prejudicial to substantial rights and newly discovered evidence.
Rule 121 further provides the effects of granting a new trial, distinguishing the consequences when a new trial is granted for errors of law from those when it is granted for newly discovered evidence.

Standards for New Trial

The Court applied the traditional requisites for new trial on newly discovered evidence derived from the Berry rule as explained in the jurisprudence.
The Court stated that the moving party must show that the evidence was discovered after trial, that it could not have been discovered with reasonable diligence before or during trial, that it is material and not merely cumulative or impeaching, and that it is of such weight that it would probably change the judgment.
The Court emphasized that the burden to demonstrate due diligence is on the movant and that the concept of due diligence entails both timely action and good faith in seeking th
