Case Summary (G.R. No. 187912-14)

Factual Background

A Commission on Audit (COA) Special Audit Team audited selected transactions of Parañaque City for 1996–1998 and discovered anomalies involving purchases of large quantities of ammunition. The audit found that procurement was effected by personal canvass without public bidding, transactions were allegedly grossly overpriced, and the supplier (VMY Trading) was not registered as an arms and ammunitions dealer with the appropriate agencies.

COA Findings and Administrative Remedies

COA issued Notices of Disallowance for the overpriced ammunition purchases. Marquez and Caunan sought reconsideration at COA and subsequently appealed but were denied relief. These administrative developments were followed by criminal charges.

Ombudsman Investigation and Informations

The Office of the Ombudsman, through the Office of the Special Prosecutor, found probable cause to file three informations against Marquez and Caunan for violation of Section 3(e) of RA 3019. Marquez and Caunan filed a joint counter-affidavit asserting propriety of the transactions and noting the pending COA appeal.

Trial Court Proceedings and Prosecution Evidence

The criminal cases were raffled initially to the Sandiganbayan Fourth Division. The prosecution presented five witnesses including a COA state auditor, city official, PNP Firearms and Explosives Division officer, and a private supplier. Documentary exhibits—disbursement vouchers, purchase requests, and authorization requests—were formally offered on January 13, 2006 (Exhibits “A” to “FFFF”) and admitted by the Sandiganbayan on March 22, 2006.

Defense Allegation of Forgery and Motions

Marquez consistently asserted that his signatures on the questioned documents were forged. He sought referral of the prosecution’s documentary evidence to the NBI for handwriting examination as early as November 24, 2003, and again in an omnibus motion (April 1, 2008) and a dedicated motion to refer (July 4, 2008). He also moved for inhibition of certain Justices; those Justices later recused, and the cases were reassigned to the Sandiganbayan 5th Division.

Prosecution’s Opposition to Referral

The prosecution opposed referral, arguing in essence that (a) the documentary evidence had already been formally offered and admitted in 2006, (b) Marquez did not assert forgery during the COA proceedings or in his counter-affidavit to the Ombudsman, and (c) Marquez’s allegations were a belated attempt to delay the trial. The prosecution invoked Section 4, Rule 129 regarding judicial admissions and noted that Caunan had identified Marquez’s signatures on the vouchers.

Sandiganbayan 5th Division’s Ruling

By resolution dated February 11, 2009, the Sandiganbayan 5th Division denied Marquez’s motion to refer the documents to the NBI. The court reasoned, citing Section 22 of Rule 132, that while expert handwriting opinion may be helpful, it is neither mandatory nor indispensable because the court can independently determine forgery. Marquez’s motion for reconsideration was denied on May 20, 2009.

Petition for Certiorari: Legal Standard for Intervention

Marquez filed a petition for certiorari asserting grave abuse of discretion amounting to lack or excess of jurisdiction by the Sandiganbayan 5th Division in denying his motion. The Supreme Court summarized the standard: certiorari will lie only where the trial court acted without jurisdiction or with patent and gross abuse of discretion—an arbitrary, capricious, or whimsical exercise of judgment amounting to evasion of a positive duty.

Constitutional Right to Due Process and to Present Defense

The Court emphasized the constitutional guarantees under Section 14, Article III of the 1987 Constitution: due process, presumption of innocence, right to be heard by counsel, and the right to compulsory process to secure the production of evidence in one’s behalf. Due process in criminal proceedings requires (a) proper exercise of judicial power by the tribunal, (b) lawful acquisition of jurisdiction over the accused, (c) an opportunity for the accused to be heard, and (d) judgment only upon lawful hearing. This constitutional framework entails a reasonable freedom for the accused to present his chosen defense.

Burden of Proof on Allegations of Forgery

The Court reiterated the hornbook rule that forgery is not presumed and must be proved by clear, positive, and convincing evidence, with the burden of proof on the party alleging forgery. To meet this burden, the accused must be afforded a reasonable opportunity to present evidence—including, where pertinent, expert examination of the signatures in the questioned documents.
