Facts

• At about 2:50 p.m. on 19 March 2003, acting on information that a certain Jacinta Marciano, alias "Intang," was selling drugs to tricycle drivers, SPO1 Elmer Amposta with CSU Edmundo Hernandez, CSU Jose Tagle, Jr. and CSU Samuel Monzon were dispatched to Barangay Alapan 1-B, Imus, Cavite.
• They waited for a tricycle travelling to or from Jacinta's house, spotted one coming out of the house with Rizaldy Sanchez as passenger, and gave chase.
• Catching up, they asked him to alight. Amposta noticed him holding a match box and asked if he could see its contents; Sanchez agreed and handed it over.
• Inside was a small transparent plastic sachet of white crystalline substance. Only then did the group accost Sanchez and the driver and bring them to the station. The custody came after the sachet, not before — which is the whole case.
• On 20 March 2003 NBI forensic chemist Salud M. Rosales certified the specimen, marked "RSC" and submitted by PO1 Edgardo Nario, positive for methamphetamine hydrochloride.
• An Information dated 20 March 2003 (Crim. Case No. 10745-03) charged Section 11, Article II, R.A. No. 9165; he pleaded not guilty, the parties stipulating only on the laboratory request, NBI certification, Dangerous Drugs Report and the sachet.
• His account differed: he and Darwin Reyes were on their way home after transporting a passenger when four armed men in an owner-type jeepney blocked their way, frisked them without explanation, and accused them of having just bought drugs. Darwin was released; he was not. He disclosed a prior, dismissed charge for the same offence.
• On 21 April 2005 the RTC of Imus, Cavite, Branch 20, convicted him — twelve to fifteen years and a ₱300,000.00 fine.
• On 25 July 2012 the Court of Appeals affirmed, reasoning the police had probable cause because he left a known dealer's house after a tip, analogising to People v. Valdez, and holding Section 21 lapses non-fatal; reconsideration denied 20 November 2012.
• On 19 November 2014 the Second Division, through Justice Mendoza, treated his mislabelled Rule 65 petition as a Rule 45 appeal and acquitted him.

Issue

Ruling

WHEREFORE, the petition is GRANTED. The assailed July 25, 2012 Decision and the November 20, 2012 Resolution of the Court of Appeals in CA-G.R. CR No. 31742 are REVERSED and SET ASIDE. Petitioner Rizaldy Sanchez y Cajili is ACQUITTED on reasonable doubt. Accordingly, the Court orders the immediate release of the petitioner, unless the latter is being lawfully held for another cause; and to inform the Court of the date of his release, or reason for his continued confinement, within ten (10) days from receipt of notice.

SO ORDERED.

Ratio

• The Court first corrected a doctrinal confusion below. Search incident to a lawful arrest presupposes a precedent, valid arrest; stop and frisk requires no arrest at all, only reasonable, articulable suspicion justifying a limited pat-down for weapons. Malacat draws the line.
• On the incident-to-arrest theory the facts simply were not there. Amposta's own testimony, read chronologically, showed the request to see the match box preceded any custodial act, and the "arrest" followed only once the shabu had been found.
• Anticipating the fallback — that the arrest occurred when the tricycle was stopped — the Court tested that theory independently and found neither the overt act nor personal knowledge: mere presence at, and departure from, a suspected dealer's house is not an overt criminal act, and an uncorroborated tip is not personal knowledge.
• The two remaining doctrines then failed on their own terms — no genuine articulable reason for a frisk, and contraband concealed rather than in plain sight, discovered not inadvertently but by a specific demand to open the container.
• Every justification foreclosed, the shabu was excluded — and being the corpus delicti, its exclusion compelled acquittal, reinforced though not strictly needed by the custody gaps.

Facts

1. At around 2:50 p.m. on 19 March 2003, acting on information that a certain Jacinta Marciano, alias "Intang," was selling drugs to tricycle drivers, SPO1 Elmer Amposta, together with CSU Edmundo Hernandez, CSU Jose Tagle, Jr., and CSU Samuel Monzon, was dispatched to Barangay Alapan 1-B, Imus, Cavite.
2. The group waited for a tricycle traveling to or from Jacinta's house. After a few minutes, they spotted a tricycle, with Rizaldy Sanchez as passenger, coming out of the house, and gave chase.
3. Having caught up with the tricycle, the officers requested Sanchez to alight; SPO1 Amposta then noticed Sanchez holding a match box and asked if he could see its contents. Sanchez agreed and handed it over voluntarily.
4. Examining the match box, Amposta found a small transparent plastic sachet containing a white crystalline substance. Suspecting a regulated drug, the group accosted Sanchez and the tricycle driver and brought both to the police station.
5. On 20 March 2003, NBI forensic chemist Salud M. Rosales certified that the specimen, marked "RSC" and submitted by PO1 Edgardo Nario, tested positive for methamphetamine hydrochloride.
6. Sanchez was charged, under an Information dated 20 March 2003 (Crim. Case No. 10745-03), with violation of Section 11, Article II, R.A. No. 9165. He pleaded not guilty at arraignment; the parties stipulated only on the existence and due execution of the laboratory request, NBI certification, Dangerous Drugs Report, and the plastic sachet itself.
7. At trial, Sanchez testified that he and a companion, Darwin Reyes, were simply on their way home after transporting a passenger to Alapan when four armed men in an owner-type jeepney blocked their way, frisked them without explanation, and accused them of having just bought drugs; Darwin was released, but Sanchez was brought to the station. He disclosed a prior, dismissed charge for the same offense before a different branch of the same court.
8. On 21 April 2005, the RTC of Imus, Cavite (Branch 20) rendered judgment convicting Sanchez, finding he had been caught in flagrante delicto in possession of shabu, crediting SPO1 Amposta's testimony absent any showing of ill motive, and sentencing him to imprisonment of twelve to fifteen years plus a P300,000.00 fine.
9. Sanchez appealed to the Court of Appeals (CA-G.R. CR No. 31742), which, in its Decision of 25 July 2012, affirmed the RTC, reasoning that the police had probable cause to stop Sanchez because he was seen leaving the house of a known drug dealer following a tip, analogizing to People v. Valdez (G.R. No. 127801), and holding non-compliance with Section 21, R.A. No. 9165's chain-of-custody procedure non-fatal since the item's integrity was preserved. Reconsideration was denied in the CA's Resolution of 20 November 2012.
10. Sanchez elevated the case to the Supreme Court via a Petition for Certiorari under Rule 65, arguing grave abuse of discretion in the CA's in flagrante delicto and Section 21 rulings.
11. The Supreme Court (Mendoza, J., Second Division) rendered the Decision under digest on 19 November 2014. Treating the petition, in the interest of substantial justice, as one for review under Rule 45 despite its mislabeling, the Court granted it and acquitted Sanchez.

Ruling

WHEREFORE, the petition is GRANTED. The assailed July 25, 2012 Decision and the November 20, 2012 Resolution of the Court of Appeals in CA-G.R. CR No. 31742 are REVERSED and SET ASIDE. Petitioner Rizaldy Sanchez y Cajili is ACQUITTED on reasonable doubt. Accordingly, the Court orders the immediate release of the petitioner, unless the latter is being lawfully held for another cause; and to inform the Court of the date of his release, or reason for his continued confinement, within ten (10) days from receipt of notice.

SO ORDERED.

Ratio

1. The Court first corrected a doctrinal confusion in the courts below: the CA had treated search-incident-to-lawful-arrest (Section 13, Rule 126§, which presupposes a precedent, valid arrest) as interchangeable with the Terry stop-and-frisk doctrine (which requires no arrest at all, only a reasonable, articulable suspicion justifying a limited pat-down for weapons) — quoting Malacat v. Court of Appeals at length to draw the line between the two.
2. Having separated the two doctrines, the Court examined the search-incident-to-arrest theory first and found it factually unavailable: SPO1 Amposta's own testimony, read chronologically, showed the request to view the match box's contents preceded any custodial act, and the "arrest" (accosting and bringing Sanchez to the station) followed only once the shabu had already been found — a reversal of the sequence Section 13, Rule 126§ requires.
3. Anticipating that the arrest might be characterized as having occurred earlier — at the moment the tricycle was stopped and Sanchez was made to alight — the Court tested that theory independently against Section 5(a) and 5(b)'s substantive requisites and found neither the "overt act" element of in flagrante delicto nor the "personal knowledge of a just-committed offense" element of hot pursuit satisfied: mere presence at, and departure from, a suspected drug dealer's house is not itself an overt criminal act, and the police's basis for suspicion was an uncorroborated tip, not personal knowledge of an offense.
4. The Court then tested, and rejected, the two remaining doctrines potentially available on facts not amounting to an arrest: stop-and-frisk (no genuine, articulable reason beyond "coming from a drug dealer's house") and plain view (the contraband was concealed, not in plain sight, and its discovery was not inadvertent but the product of a specific demand to open the container).
5. With every available justification for a warrantless search foreclosed, the shabu was excluded as the fruit of an unconstitutional search — and, being the corpus delicti itself, its exclusion compelled acquittal, reinforced (though not strictly necessary to the result) by the independently fatal chain-of-custody gaps.

Doctrine

1. A lawful arrest must precede, not follow, a search purportedly incidental to it: "[T]he law requires that the search be incidental to a lawful arrest. Therefore it is beyond cavil that a lawful arrest must precede the search of a person and his belongings; the process cannot be reversed... what happened in this case was that a search was first undertaken and then later an arrest was effected based on the evidence produced by the search."
2. Definition and mechanics of arrest, applied to find none had yet occurred: "Arrest is defined under Section 1, Rule 113§ of the Rules of Court as the taking of a person into custody that he may be bound to answer for the commission of an offense. Under Section 2, of the same rule, an arrest is effected by an actual restraint of the person to be arrested or by his voluntary submission to the custody of the person making the arrest."
3. Search incidental to lawful arrest is analytically distinct from stop-and-frisk, per Malacat v. Court of Appeals: in the former, "the precedent arrest determines the validity of the incidental search... the process cannot be reversed"; the latter is "a limited protective search of outer clothing for weapons," requiring only reasonable, articulable suspicion, not probable cause or a prior arrest.
4. Elements of a valid in flagrante delicto arrest: "(1) the person to be arrested must execute an overt act indicating that he has just committed, is actually committing, or is attempting to commit a crime; and (2) such overt act is done in the presence or within the view of the arresting officer."
5. Elements of the plain view doctrine: "(1) the law enforcement officer in search of the evidence has a prior justification for an intrusion or is in a position from which he can view a particular area; (2) the discovery of the evidence in plain view is inadvertent; and (3) it is immediately apparent to the officer that the item he observes may be evidence of a crime."

• The Decision is explicit that its ruling does not merely restate the general in flagrante/hot pursuit rules but adds a distinct, independently sufficient sequencing defect: even a factually strong warrantless-arrest case would not save a search that, on the officer's own account, was conducted before any custodial act.
• The Court is equally careful to distinguish this case from precedent (People v. Valdez, invoked by the CA) where the object of the search was itself already visibly in the suspect's grasp or the tip was corroborated by more specific, matching details — neither of which was true here, where only a generic informant's tip about "tricycle drivers" and an unremarkable match box were involved.

• Sanchez v. People (2014) is a direct, granular application of Sections 1 and 2, Rule 113§'s definition and mechanics of arrest, resolving the case by close chronological parsing of the arresting officer's own testimony to determine the precise moment (if any) custody began — and finding that moment came only after, not before, the search that produced the evidence.
• Read together with Luz and Homar, this case supplies the doctrinal variant in which the "search-before-arrest" sequencing problem, rather than an "accosting-is-not-arresting" characterization problem, is what defeats the prosecution.
