Can a conviction under the Comprehensive Dangerous Drugs Act of 2002 be reversed on the basis of improper adherence to the chain of custody rule, despite the prosecution's presentation of all links in the custody chain?
Case Title:
People of the Philippines vs. Chris John Custodio y Argote
G.R. No. 251741, June 14, 2023
Facts of the Case:
Chris John Custodio, also known as "Bolongkoy," was charged with violating Sections 5 and 11 of Republic Act No. 9165, otherwise known as the Comprehensive Dangerous Drugs Act of 2002. In Criminal Case No. 2015-23224, Custodio was accused of illegally selling 0.04 grams of methamphetamine hydrochloride ("shabu") to PO3 Al Lester Avila, who acted as a poseur buyer during a buy-bust operation. In Criminal Case No. 2015-23225, Custodio was also charged with illegal possession of 3.07 grams of shabu.
Custodio pleaded not guilty to both charges and the cases were consolidated. The prosecution presented several witnesses, including members of the buy-bust team and other law enforcement officers. The team testified that they coordinated a buy-bust operation based on information from a confidential informant, during which Custodio was arrested after selling the illegal substance. The defense, however, claimed that Custodio was framed and that he was illegally arrested without drugs in his possession.
The trial court convicted Custodio of both illegal sale and possession of dangerous drugs. He was sentenced to life imprisonment for the sale of drugs and given a sentence of 12 to 14 years for possession. The Court of Appeals affirmed the trial court’s decision, ruling that the integrity of the drugs was preserved and the chain of custody was followed, despite the absence of insulating witnesses during the actual filling out of the inventory.
Primary Issue in the Supreme Court:
Was the chain of custody of the seized drugs properly followed, and did the procedural lapses in its observance justify the acquittal of Custodio?
Supreme Court Decision:
The Supreme Court reversed the conviction of Custodio. It ruled that the prosecution failed to justify why the physical inventory and taking of photographs of the seized drugs were conducted at the police station rather than at the place of arrest, as required by law. The failure to comply with this rule without providing any valid justification broke the first and most critical link in the chain of custody. The Court emphasized that subsequent compliance with the requirements of the chain of custody cannot cure this initial breach. Consequently, the Court ruled that Custodio must be acquitted due to the failure of the prosecution to prove the integrity and identity of the corpus delicti beyond reasonable doubt.
Dispositive Portion:
The Motion for Reconsideration is GRANTED. The Supreme Court REVERSES its previous decision and ACQUITS Chris John Custodio y Argote of all charges. He is ORDERED IMMEDIATELY RELEASED from detention unless he is being lawfully held for another cause.
Thought-provoking Question:
Should law enforcement officers be strictly penalized for breaches in the chain of custody, even when dangerous drugs are involved, to prevent potential abuse of power?
Doctrines Quoted:
-
Chain of Custody Rule
"In case of warrantless seizures, the inventory and taking of photographs generally must be conducted at the place of seizure. The failure to comply with this requirement without a valid justification breaks the chain of custody and casts doubt on the integrity of the evidence." -
People v. Casa
"If the prosecution fails to explain why the inventory was not conducted at the place of arrest, the chain of custody is irreparably broken, and the seized items are rendered inadmissible as evidence." -
Presumption of Innocence
"Accused-appellant’s right to liberty cannot be unjustly restrained when the chain of custody is compromised. Courts must be vigilant in upholding constitutional rights, particularly when procedural lapses occur."

🎓 In
this brief but insightful discussion, we explore a landmark decision of the
Supreme Court of the Philippines that emphasizes the strict procedural
safeguards required in drug-related arrests. This video is intended to assist law
students, bar examinees, and even practicing lawyers in
remembering the most critical doctrines from this case — especially
those pertaining to the chain of custody rule in drug prosecutions under
R.A. 9165.
📚 Nature of the Case:
Criminal Law – Violation of Sections 5 and 11 of Republic Act No. 9165
(Comprehensive Dangerous Drugs Act of 2002)
📌 Case Title:
People of the Philippines vs. Chris John Custodio y Argote a.k.a.
“Bolongkoy”
G.R. No. 251741, Promulgated on June 14, 2023
🔍 Brief Summary of the Case:
Chris John Custodio was convicted by the RTC and affirmed by the CA for illegal
sale and possession of “shabu.” He was arrested in a buy-bust operation, but
the inventory of the seized items was done at the police station — not at the
place of arrest. The Supreme Court granted his Motion for Reconsideration,
reversed its earlier ruling, and acquitted him, stressing that the failure
to justify the deviation from the required procedure in the chain of custody
rule is fatal to the prosecution.
⚖️ Core Legal Issue:
Is non-compliance with the procedural requirement of conducting inventory
and photographing the seized items at the place of arrest — without valid
justification — fatal to the prosecution in drug cases?
✅ Ruling of the Supreme Court:
Yes. The Court held that the first and most critical link in the chain
of custody was broken. The prosecution failed to justify why the inventory was
not conducted at the place of arrest, thereby casting doubt on the integrity
and identity of the corpus delicti.
💭 In the pursuit of justice and
drug enforcement, should courts relax procedural rules when police are acting
in good faith, or should strict compliance always be non-negotiable?
🎓 TOP 10 DOCTRINES ON CHAIN
OF CUSTODY AND PROCEDURAL COMPLIANCE (G.R. No. 251741)
Source: Supreme Court Decision, June 14, 2023
- Inventory
Must Be at the Place of Seizure
“Inventory and photographing of seized
items must be conducted at the place of arrest, unless justified.”
(People v. Custodio, citing People v. Casa)
- Failure
to Justify Change of Venue Is Fatal
“No valid explanation was given for
moving the inventory from the arrest site to the police station; thus, the
first chain link was broken.”
(SC Decision, p. 6)
- Subsequent
Compliance Does Not Cure Initial Breach
“Later compliance cannot cleanse an
incipient defect in the chain of custody.”
(People v. Ismael, cited in the ruling)
- Chain
of Custody Is a Safeguard Against Planting and Switching
“A broken chain creates reasonable doubt
as to the identity and integrity of the seized drugs.”
(Decision, p. 7)
- Burden
on the Prosecution to Justify Deviation
“Police must offer a sensible,
consistent reason — not generic or post-hoc — for deviating from standard
procedure.”
(People v. Casa, cited at p. 6)
- Insulating
Witnesses Must Be Present at Inventory
“Their late presence at the police
station does not satisfy the law.”
(People v. Custodio, SC ruling)
- Police
Affidavits Must Show Justification for Deviation
“The required justification must be
reflected in the sworn affidavits of the arresting officers.”
(Decision, p. 6-7)
- Violation
of Chain of Custody Is a Ground for Acquittal
“Failure to preserve integrity of seized
items warrants outright acquittal.”
(People v. Custodio, p. 8)
- Strict
Procedural Compliance Upholds Constitutional Rights
“Efforts to fight drugs must not
override the rights of the accused.”
(People v. Macud, quoted in final ruling)
- Courts
Must Be Extra Vigilant in Drug Cases
“Courts are reminded to be extra
vigilant in trying drug cases to avoid wrongful convictions.”
(People v. Rangaig, cited in conclusion)
