During the second day of Vice President Sara Duterte's impeachment trial at the Senate, legal counsel for the defense, Atty. Carlo Narvasa, challenged the admissibility of digital evidence. Narvasa objected to an affidavit from NBI agent John Mark Calilung, arguing that the presented documents were mere photocopies lacking original USB or CD appendages and wet signatures. Conversely, private prosecutor Amando Ligutan argued that under the 2019 Amendments to the Rules on Evidence, electronic copies and photocopies are considered originals. The Supreme Court rules state that a printout accurately reflecting stored data qualifies as an original. Presiding Officer Senator Francis "Chiz" Escudero noted that while the court recognizes exceptions to the Original Document Rule, parties should present original documents during trial to ensure efficiency and avoid delays in the proceedings.
