Case Summary (G.R. No. 81561)

Issues on Appeal

  1. Whether the trial court erred in admitting evidence allegedly obtained through unconstitutional search and seizure.
  2. Whether appellant’s constitutional rights during custodial proceedings were violated.
  3. Whether the trial court should have credited appellant’s explanation of the parcels’ provenance.

Search and Seizure Analysis

The exclusionary rule under the 1987 Constitution (Art. III, Secs. 2–3) bars evidence procured through unlawful government searches.

Their presence did not convert a lawful private inspection into a constitutional violation. Accordingly, the evidence was admissible.

Custodial Proceedings and Miranda Rights

Appellant contended his rights under Article III were ignored during NBI interrogation. The records, however, show that appellant invoked his right to remain silent and refused to give a written statement. NBI officers testified, without contradiction, that appellant was duly informed of his rights. In the absence of evidence proving otherwise, the presumption of regular performance by law enforcement stands, and no unconstitutional custodial interrogation occurred.

Credibility of Appellant’s Explanation

Appellant’s claim that an unnamed German national instructed him to ship the parcels and paid him ₱2,000 lacks credibility. The Supreme Court applied the presumption of ownership (Rule 131, Sec. 5[j]) and weighed appellant’s self‐serving denial against the improbability of entrusting valuable contraband to a half‐hour acquaintance.
