Could the procedural lapses in the chain of custody of seized drugs in a buy-bust operation invalidate the prosecution's evidence and lead to an acquittal despite a legitimate drug operation?
CASE TITLE:
FACTS:
Quirino Bumanglag y Sumalpon was accused
of violating Section 5 (illegal sale of dangerous drugs) and Section 12
(illegal possession of drug paraphernalia) of Republic Act No. 9165, also known
as the Comprehensive Dangerous Drugs Act of 2002. On November 9, 2011, a
buy-bust operation was conducted based on information from an informant named
“Nicole.” Police Officer Jhimelle Dela Cruz posed as the buyer, and upon
completing the transaction, Bumanglag was arrested. The police recovered a
small amount of methamphetamine hydrochloride (shabu), drug paraphernalia, and
marked buy-bust money.
During the trial, Bumanglag pleaded not
guilty and claimed that the operation was a setup. He asserted that he was
merely at the scene to meet "Nicole," whom he knew personally, and
that he had no involvement in any drug activity. The trial court, however,
convicted him, sentencing him to life imprisonment for the illegal sale of
drugs and imposing a fine of PHP 500,000. For the illegal possession of drug
paraphernalia, he was sentenced to six months and one day to two years of
imprisonment, along with a fine of PHP 20,000.
On appeal, Bumanglag raised several
procedural issues regarding the handling of evidence, particularly the chain of
custody. He pointed out that the marking of the seized items was not done at
the scene of the arrest but only at the police station, and that the required
witnesses during the inventory were incomplete. The Court of Appeals affirmed
the trial court’s decision, giving weight to the presumption of regularity in
the performance of official duties by the police officers.
ISSUE:
Did the procedural lapses in the chain
of custody of the seized drugs compromise the integrity of the evidence,
thereby warranting the acquittal of the accused?
RULING:
Yes. The Supreme Court acquitted
Bumanglag, emphasizing the prosecution’s failure to establish an unbroken chain
of custody. The marking of the seized drug was not done immediately at the
scene of the arrest, as required by law. Instead, it was marked only at the
police station, without any explanation for the delay. This lapse in procedure
created a significant break in the chain of custody, making the evidence
susceptible to tampering or contamination.
Furthermore, the required witnesses
during the inventory of the seized items were not complete. Only the barangay
chairman was present, while representatives from the media and the Department
of Justice (DOJ) were absent. The Supreme Court ruled that the presumption of
regularity in the performance of duties cannot substitute for strict compliance
with the chain of custody requirements under Republic Act No. 9165.
Without an intact chain of custody, the
integrity and authenticity of the corpus delicti (the drugs) were compromised,
leading to reasonable doubt about the guilt of the accused. The procedural
lapses in this case were not excusable under the "saving clause" of
the law, as the prosecution failed to provide justifiable grounds for these
lapses.
DISPOSITIVE PORTION:
The Court ordered the acquittal of
Quirino Bumanglag y Sumalpon and directed the Bureau of Corrections to
immediately release him, unless there are other lawful causes for his
detention.
Is the public at risk when procedural
lapses in drug operations can result in acquittals, even if the suspects were
involved in illegal drug activities?
IMPORTANT DOCTRINES:
- Chain
of Custody Rule – Section 21 of Republic Act No. 9165 requires the
immediate marking, inventory, and photographing of seized drugs in the
presence of the accused, a media representative, a DOJ representative, and
an elected public official. Any deviation must be justified, or it could
lead to the acquittal of the accused due to compromised evidence.
- Presumption
of Regularity in Performance of Duties – This presumption cannot replace
strict adherence to legal procedures, particularly in drug-related cases
where the integrity of the evidence is crucial.
- Saving
Clause – Non-compliance with the chain of custody rule may be excused only
if the prosecution can provide justifiable grounds and demonstrate that
the integrity and evidentiary value of the seized items were preserved.
CLASSIFICATION:
This case falls under Criminal Law,
specifically related to violations of the Comprehensive Dangerous Drugs Act (RA
9165).

📚 10 DOCTRINES YOU
MUST REMEMBER (For Law School & Bar Exam):
- Immediate Marking Required:
Marking of seized drugs must be done at the place of arrest. Delayed marking exposes the drugs to tampering.
(G.R. No. 228884, p. 25) - Four Links of Chain of Custody:
Seizure, turnover to investigator, transfer to forensic chemist, and submission to court must be clearly shown.
(p. 24-25) - Section 21 Compliance is Mandatory:
Inventory and photography must be conducted in the presence of the accused, DOJ rep, media, and elected official.
(p. 23) - One Witness Not Enough:
Presence of only one witness during inventory (e.g., barangay chairman) is insufficient without justifiable grounds.
(p. 28-29) - Presumption of Regularity Not Absolute:
Cannot override lapses in the chain of custody; must yield to evidence of procedural non-compliance.
(p. 32) - Saving Clause Has Conditions:
Must show (1) justifiable ground and (2) proof of integrity of seized drugs to invoke the saving clause.
(p. 31) - Absence of Explanation is Fatal:
Failure to explain why inventory and marking were not done at the scene is a fatal flaw.
(p. 27) - Barangay Official’s Role Must Be Actual:
Mere signing of documents post-facto does not satisfy the requirement of presence during inventory.
(p. 29) - Appellate Courts Can Revisit Chain of Custody:
Even if not raised below, higher courts must assess if chain of custody was followed to preserve due process.
(p. 32) - Acquittal is Required for Broken Chain:
Violation of custody rules, without valid excuse, mandates acquittal to uphold constitutional safeguards.
(p. 33)
