Facts

• Ray Shu, President of 3A Apparel Corporation, complained to the NBI against Metrobank employees Jaime Dee and Edwin So (who signed as witnesses), notaries Ramon Miranda and Enriqueto Magpantay, and Larry Macillan (who submitted the papers to the Registrar of Deeds) for falsifying two deeds of real estate mortgage on which Metrobank had relied to foreclose properties securing 3A Apparel's loan.
• NBI Questioned Documents Report No. 746-1098 found Shu's signatures on the deeds did not match the standard samples he submitted. Note whose samples — only his own.
• Before the City Prosecutor the respondents argued denial of due process: the NBI never required them or Metrobank to submit sample signatures, the report compared only Shu's unilaterally submitted specimens, and other documents in Metrobank's possession showed the signatures genuine.
• On 25 June 1999 the City Prosecutor found no probable cause, holding the NBI report inconclusive, the similarities between the deeds and respondents' specimens "so striking that even a layman could see" one hand wrote them, sufficient consideration existing since Shu benefited from the credit line, and regularity presumed in the notaries' performance despite Shu's use of an already-cancelled passport.
• On appeal the Secretary of Justice reversed, holding the prosecutor failed to give due weight to the NBI's expert findings, entitled to full faith and credit absent proof of irregularity, and that those findings with Shu's disclaimer of signing any promissory note and the lack of proof he received loan proceeds established probable cause — the "credit line" reasoning being "gratuitous and conjectural." Reconsideration was denied.
• On 19 June 2007 the Court of Appeals annulled her Resolution, finding denial of due process at both the NBI and DOJ stages and holding that greater weight should attach to those who personally investigated — the NBI agent and the city prosecutor — over those who did not. Reconsideration was denied 4 April 2008.
• On 23 April 2014 the Second Division, through Justice Brion, granted the petition.

Ruling

WHEREFORE, we GRANT the petition and REVERSE and SET ASIDE the decision of the Court of Appeals dated June 19, 2007 and its resolution dated April 4, 2008.

SO ORDERED.

Ratio

• The due-process objection had to go first, since a violation would have doomed the Resolution regardless of the merits — and it failed twice: the NBI stage cannot generate one by its very nature, and any DOJ-stage defect was cured by the respondents' own motion.
• The CA's central premise was structurally wrong. The investigating prosecutor's resolution is always subject to the reviewing authority's power to reverse, modify or affirm, and it is the reviewing authority's assessment — not the original investigator's — that stands unless tainted by grave abuse.
• Tested against that standard the Secretary's reasoning held — a holistic review, not a one-sided reliance on the NBI report and Shu's assertions.
• And the prosecutor's original resolution had a deeper defect. He did not merely find the evidence insufficient; he affirmatively resolved a live, expert-dependent question — the authenticity of signatures, which Section 22, Rule 132 commits to the trial judge's own examination.

Facts

1. Ray Shu, President of 3A Apparel Corporation, filed a complaint before the National Bureau of Investigation (NBI) charging respondents — Metrobank employees Jaime Dee and Edwin So (who signed the deeds as witnesses), Ramon Miranda and Enriqueto Magpantay (notaries who notarized the deeds), and Larry Macillan (who submitted them to the Registrar of Deeds) — with falsifying two deeds of real estate mortgage that Metrobank had relied upon to foreclose properties securing 3A Apparel's loan. The NBI's Questioned Documents Report No. 746-1098 found that Shu's signatures on the deeds did not match the standard sample signatures he had submitted to the NBI.
2. Respondents, in their counter-affidavits before the City Prosecutor of Makati (to whom the NBI referred its findings), argued they were denied due process during the NBI investigation because the NBI never required them or Metrobank to submit sample signatures for comparison, that the NBI report only compared Shu's own unilaterally-submitted samples, and that other documents in Metrobank's possession showed Shu's signatures on the deeds were genuine.
3. The City Prosecutor (Resolution dated 25 June 1999) found no probable cause and dismissed the complaint, holding the NBI report inconclusive, finding the signature similarities between the deeds and respondents' submitted specimens "so striking that even a layman could see" they were written by the same person, finding sufficient consideration existed for the mortgages (Shu having benefited from the credit line), and presuming regularity in the notaries' performance despite Shu's use of an already-cancelled passport.
4. On appeal, the Secretary of Justice reversed, holding the city prosecutor failed to give due weight to the NBI's expert findings (entitled to full faith and credit absent proof of irregularity), and that the expert evidence, Shu's disclaimer of having signed any promissory note, and the lack of proof he received loan proceeds together established probable cause; she characterized the city prosecutor's "credit line" consideration finding as "gratuitous and conjectural." Respondents' motion for reconsideration was denied.
5. Respondents brought a Rule 65 certiorari petition to the Court of Appeals, alleging grave abuse of discretion. The CA granted the petition and annulled the Secretary's resolution, holding respondents were denied due process at both the NBI stage (not furnished the complaint, not required or allowed to answer) and the DOJ stage (not furnished the petition for review, not required to comment), and that greater weight should attach to the findings of those who personally investigated (the NBI agent, the city prosecutor) over those who did not (the NBI chiefs, the Secretary). Petitioner's motion for reconsideration was denied.
6. Petitioner filed the instant Rule 45 petition. The Supreme Court (Brion, J., Second Division) rendered the Decision under digest on 23 April 2014, granting the petition.

Ruling

WHEREFORE, we GRANT the petition and REVERSE and SET ASIDE the decision of the Court of Appeals dated June 19, 2007 and its resolution dated April 4, 2008.

SO ORDERED.

Ratio

1. The Court first cleared the due-process objection, since a finding of denial of due process would have independently doomed the Secretary's resolution regardless of the probable-cause§ merits: it held the NBI stage could not, by its very nature as a non-adjudicative investigatory body, give rise to a due-process violation, and that the DOJ-stage defect (if any) was cured by respondents' own motion for reconsideration.
2. With the due-process objection cleared, the Court proceeded to the CA's central premise — that the city prosecutor's findings, made by the officer who "personally" investigated, should prevail over the Secretary's. The Court rejected this premise as contrary to the settled executive structure of preliminary investigation: the investigating prosecutor's resolution is always subject to the reviewing authority's power to reverse, modify, or affirm, and it is the reviewing authority's own assessment — not the original investigator's — that stands unless shown to be tainted by grave abuse of discretion.
3. Testing the Secretary's resolution against the grave-abuse standard, the Court found her reasoning sound and evidence-based (a "holistic review," not a one-sided reliance on the NBI report and Shu's own assertions), leaving no basis for judicial interference.
4. Finally, the Court exposed the deeper defect in the city prosecutor's original resolution: he had not merely found the evidence insufficient, but had affirmatively resolved a live, expert-evidence-dependent question (the authenticity of the signatures) that Section 22, Rule 132 commits to the trial judge's own independent examination — a determination inappropriate for the preliminary-investigation stage, further reinforcing why his resolution did not deserve controlling weight over the Secretary's review.

Doctrine

1. "The determination of probable cause is essentially an executive function, lodged in the first place on the prosecutor who conducted the preliminary investigation. The prosecutor's ruling is reviewable by the Secretary who, as the final determinative authority on the matter, has the power to reverse, modify or affirm the prosecutor's determination." — the Decision's own internal sub-heading and the core Topic-8 holding.
2. The Secretary of Justice's findings are not subject to judicial interference except upon a showing of grave abuse of discretion amounting to lack or excess of jurisdiction, gross misapprehension of facts, a patent and gross evasion of positive duty or virtual refusal to perform a duty enjoined by law, or action outside the contemplation of law — the Doctrine of Non-Interference standard, applied here to the Secretary's own review-stage determination.
3. The NBI's functions are merely investigatory and informational, not judicial or quasi-judicial; it cannot determine probable cause, and its findings are merely recommendatory, subject to the investigating prosecutor's and the Secretary's independent action, citing Cabarrus, Jr. v. Bernas.
4. Sufficient compliance with due process exists when a party is given the opportunity to be heard through a motion for reconsideration, curing any initial notice defect, citing P/Insp. Artillero v. Casimiro.
5. An investigating prosecutor's resolution that delves into the merits of a party's defense — assessing the comparative authenticity of evidence such as signatures — improperly encroaches on matters "better ventilated during trial proper than at the preliminary investigation level," since "[t]he preliminary investigation is not the occasion for the full and exhaustive display of the parties' evidence," and "in determining probable cause, the average man weighs facts and circumstances without resorting to the rules of evidence that, as a rule, is outside his technical knowledge."
6. Probable cause requires only facts sufficient to support a prima facie case — "mere probability of guilt," more than bare suspicion but less than the evidence required for conviction — applied here to the elements of falsification of public documents under Article 171 of the Revised Penal Code:
   1. The offender is a private individual or a public officer/employee who did not take advantage of official position.
   2. He committed any of the acts of falsification enumerated in Article 171.
   3. The falsification was committed in a public, official, or commercial document.

• The ruling does not hold that the original investigating prosecutor's findings are irrelevant or undeserving of any weight; it holds only that, once a reviewing authority (the Secretary of Justice) has exercised its review power and reached a reasoned, evidence-based contrary conclusion, courts may not simply prefer the original investigator's view on the theory that personal involvement in fact-gathering confers superior reliability — that would effectively nullify the review mechanism itself.
• The holding on the NBI's non-adjudicative character is likewise specific to agencies performing purely investigatory/recommendatory functions; it does not extend to bodies vested with actual quasi-judicial preliminary-investigation authority.

• Shu v. Dee directly illustrates Topic 8's core mechanism: an investigating prosecutor's resolution is not final but is subject to review, reversal, modification, or affirmance by a higher prosecutorial authority (the Secretary of Justice), whose own resulting determination — not the original investigator's — commands deference from the courts absent grave abuse of discretion.
