The Rules on Electronic Evidence (A.M. No. 01-7-01-SC), promulgated on July 17, 2001, and effective August 1, 2001, originally applied only to civil, quasi-judicial, and administrative proceedings. However, by virtue of a Supreme Court Resolution dated September 24, 2002, these rules were extended to criminal cases, effective October 14, 2002. This extension is binding and has been affirmed in several jurisprudential rulings, despite its omission in some published versions of the Rules. As such, criminal trial lawyers must regard these Rules as fully applicable to criminal litigation.
The Rules define electronic documents and digital/electronic signatures as the legal equivalents of written documents and handwritten signatures. This includes emails, chat logs, digital photographs, CCTV footage, digital audio or video recordings, and similar data. Under the Best Evidence Rule (Rule 4), printouts or readouts of electronic data that accurately reflect the stored information are treated as "originals." These may be admitted into evidence provided that their authenticity is not contested or that producing the original would be unjust or impractical.
Authentication under Rule 5 is a mandatory requirement. The party offering the electronic document must prove its integrity and authorship through one or more of the following means: a digital signature, a secure system or device authorized by law, or other evidence establishing the reliability of the method used. Electronically notarized documents that conform to SC guidelines are deemed public documents. For purposes of credibility and admissibility, trial lawyers must be prepared to lay the foundation for such authentication either through system logs, expert testimony, or other corroborating evidence.
Under Rule 6, electronic signatures are accepted as functional equivalents of handwritten ones. The law presumes, unless rebutted, that the electronic signature belongs to the person purported to have signed the document, that it remained unaltered during the validity of the security certificate, and that the document itself was not altered. These presumptions aid prosecution when messaging or signed digital files are offered in evidence.
In determining the evidentiary weight of electronic evidence under Rule 7, courts may consider factors such as the reliability of the system used to generate, store, or transmit the data, the identification of the originator, the integrity of the method, and the qualifications of witnesses explaining the data. This offers defense counsel an opportunity to challenge these aspects to reduce the probative value of such evidence.
Rule 8 provides that electronic business records may be admitted as exceptions to the hearsay rule if made contemporaneously with the event, kept in the regular course of business, and authenticated by a qualified witness such as a custodian. If, however, the source appears unreliable or untrustworthy, the document may be excluded.
Rule 9 allows the use of sworn affidavits to establish the authenticity and integrity of electronic documents. However, the affiant must confirm the affidavit in open court and be subjected to cross-examination. This dual mechanism of affidavit and oral testimony allows flexibility for offering and testing electronic evidence.
Under Rule 10, the court may allow electronic testimony through video conferencing or similar means upon motion and after a summary hearing. The court ensures that the parties' rights are protected, especially regarding the confrontation of witnesses. Ephemeral communications like live chats or phone calls are admissible if properly recorded and authenticated.
In terms of jurisprudence, the case of People v. Eul Vincent O. Rodriguez (G.R. No. 263603, October 9, 2023) is instructive. In this qualified trafficking case, Facebook messages and Skype video recordings were admitted in evidence despite objections citing the Anti-Wiretapping Law and the Data Privacy Act. The Supreme Court ruled that Skype and internet-based communications do not fall under the prohibitions of the Anti-Wiretapping Law and that the DPA permits the processing of personal data when necessary for criminal proceedings. Similarly, in People v. Enojas (718 SCRA 313, 2014), the Court confirmed that the Rules on Electronic Evidence apply to criminal cases, correcting an earlier obiter dictum in Ang v. People that had suggested otherwise.
To synthesize the doctrinal and procedural implications for criminal trial lawyers: First, always ensure the Rules are invoked and their applicability to criminal cases is properly cited (relying on Enojas if challenged). Second, prepare to authenticate digital evidence using affidavits, expert testimony, and system integrity records. Third, comply with the Best Evidence Rule by producing the original digital output or its certified equivalent. Fourth, always preserve and present a clear chain of custody and system integrity logs from the point of seizure to courtroom presentation. Fifth, use business records exceptions to overcome hearsay challenges, particularly in cases involving corporate, financial, or telco data. Sixth, anticipate and preempt objections based on the Anti-Wiretapping Law or DPA, using Rodriguez to establish admissibility. Seventh, work with technical experts to validate the system reliability. Eighth, offer affidavits that can be affirmed in open court to lay foundation. Ninth, utilize electronic testimony when witnesses cannot physically appear. And tenth, ensure all digital evidence offered meets the standards of reliability, authenticity, and relevance under these Rules.
In conclusion, mastery of the Rules on Electronic Evidence is indispensable for Filipino trial lawyers engaged in criminal litigation. These Rules now play a pivotal role in the admissibility and probative value of modern forms of digital evidence. Strategic and doctrinal familiarity with these rules and relevant case law is a critical skill set for successful trial advocacy in the digital age.
