The Torn Seal and the Missing Barangay Witness
At 11:20 p.m., a buy-bust team of five arrested 'Aling Nena' in a narrow alley after a poseur-buyer handed her ₱6,000 in marked bills and received two heat-sealed sachets containing a total of 2.4 grams of suspected shabu. No barangay official was present; the team leader said the barangay captain could not be reached. A radio stringer arrived at 12:40 a.m. at the police station and witnessed the inventory. The sachets were marked 'A-1' and 'A-2' at the station at 1:00 a.m., photographed, and placed in a plastic envelope. The forensic chemist received them at 9:00 a.m. the next day. At trial, the defense points out that one sachet's seal was torn and the chemist recorded only 2.3 grams. The investigating officer admits he did not prepare a chain-of-custody form.
1. Evaluate compliance with Section 21 of RA 9165, as amended by RA 10640. Which defects are curable and which are fatal? Reason from the purpose of the rule.

Section 21 exists to prevent switching, planting, or contamination. It requires inventory and photographs immediately after seizure, at the place of seizure or the nearest police station, in the presence of the accused or his representative and two witnesses: an elected public official and a DOJ or media representative. Here, the team had no elected official and no documented, genuine effort to secure one; the barangay captain's unavailability was asserted but not shown in the record. The marking was delayed until the station, which can be acceptable if the delay is explained, but the team also failed to prepare a chain-of-custody form. The fatal facts are the torn seal and the 0.1-gram discrepancy. The saving clause permits noncompliance where there is a justifiable reason and the integrity of the evidence is preserved. Missing a witness may be saved by a documented reason plus an unbroken chain. A torn seal and unexplained weight loss go directly to integrity and are not cured by the media witness. The court should sustain the objection unless the prosecution explains the seal and weight through the chemist and all handlers.
2. What should the investigator have done from arrest to laboratory delivery? Give a step-by-step protocol.

Before the operation, coordinate with the barangay and arrange a DOJ or media witness; prepare evidence kits and a chain-of-custody form. At the scene, arrest, warn the accused, and mark each sachet immediately with initials, date, and time. Conduct the inventory and photograph in the presence of the accused and the two witnesses; record the exact weight and condition. Seal each item with tamper-evident tape; have the accused and witnesses sign the seal or the form. Turn over the items to the evidence custodian, who logs the time, date, and receiving person. Deliver to the forensic laboratory with a request; the chemist must record the condition of the seal, weight, and tests. Every transfer must be documented. If a witness is unavailable, record the effort, the time of call, and the reason, and secure an alternative witness. The point is not ritual; it is a documented, unbroken link from seizure to court.
3. If the court excludes the shabu, may the prosecution still convict Aling Nena on the poseur-buyer's testimony and the marked money? Explain.
Read the worked answer
Probably not for the sale of shabu. In a drug sale, the corpus delicti is the prohibited drug itself. The poseur-buyer can testify to the transaction, and the marked money can show consideration, but without the drug as a properly identified exhibit the prosecution cannot prove that the substance sold was shabu. The defense of frame-up does not need to be strong where the prosecution's chain fails; the burden remains on the prosecution. A conviction might still be possible on a different charge only if independent evidence establishes the offense, but on the facts here the sale case collapses. The court should acquit if reasonable doubt remains. The lesson for the investigator is that the case is won or lost at the seizure and marking stage, not at the chemist's desk.
