The rules on evidence taken abroad through Letters of Request mark a key update in Philippine remedial law for transnational civil and commercial litigation. For the 2026 Bar, Section 18 of A.M. No. 25-02-17-SC is high-yield because essay questions frequently test the precise conditions for substituting foreign-taken evidence for live testimony while safeguarding the adverse party’s right to notice and cross-examination.

Core Legal Basis and Definition

Core Legal Basis: A.M. No. 25-02-17-SC (promulgated March 4, 2025), “Rules on the Transmission and Execution of Letters of Request for Taking of Evidence in Civil or Commercial Matters under the 1970 Hague Evidence Convention,” Section 18.

Section 18 provides:

At the trial or upon the hearing of a motion or an interlocutory proceeding, any part or all of the evidence taken abroad, so far as admissible under the Rules of Evidence, may be used against any party who was present or represented at the taking of the evidence or who had due notice thereof, in accordance with any one of the following provisions:
(a) The evidence taken abroad may be used by any party for the purpose of contradicting or impeaching the testimony of the person examined if presented as a witness;
(b) The evidence taken abroad of a party or of any one who at the time of the taking was an officer, director, or managing agent of a public or private corporation, partnership, or association which is a party may be used by an affected party for any purpose;
(c) The evidence taken may be used by any party for any purpose if the court finds: (i) that the person examined is dead; or (ii) that the person examined is out of the Philippines unless it appears that their absence was procured by the party offering the evidence taken; or (iii) that the person examined is unable to attend or testify because of age, sickness, infirmity, or imprisonment; or (iv) that the party offering the evidence taken abroad has been unable to procure the attendance of the person examined by subpoena; or (v) upon application and notice, that such exceptional circumstances exist as to make it desirable, in the interest of justice and with due regard to the importance of presenting the testimony of the person examined orally in open court, to allow the evidence taken to be used; and
(d) If only part of the evidence taken is offered in evidence by the Requesting Party, the affected party may require them to introduce all of it which is relevant to the part introduced.

Definition and Scope: “Evidence taken abroad” refers to testimonial, documentary, or object evidence (including expert testimony) obtained pursuant to a Letter of Request under these Rules in civil or commercial matters, when the 1970 Hague Evidence Convention is in force between the Philippines and the Requested State. The Rules do not preclude ordinary depositions under the Rules of Court for non-Contracting States.

Essential Requisites / Elements / Components

For evidence taken abroad to be usable under Section 18, all of the following must concur:

Admissibility under the Rules of Evidence — It must independently satisfy relevancy, competency, and exclusionary rules (hearsay exceptions, privileges, etc.).
Due-process prerequisite (notice/participation) — It may be used only against a party who was present or represented at the taking or who had due notice thereof. This protects the right to cross-examine.
Must fall under one of the four avenues of use:
- (a) Limited to impeachment/contradiction — Available to any party when the examined person testifies at trial.
- (b) Any purpose (against party or its officers) — The examined person must be a party or an officer/director/managing agent of a party at the time of taking; usable by an affected party for any purpose.
- (c) Any purpose upon court finding of unavailability or exceptional circumstances — The court must affirmatively find at least one of the five grounds (dead; out of the Philippines not procured by offeror; unable due to age/sickness/infirmity/imprisonment; unable to procure by subpoena; or exceptional circumstances justifying use in the interest of justice, giving due regard to the preference for live oral testimony).
- (d) Completeness rule — If the Requesting Party offers only part, the affected party may compel introduction of all relevant portions.

The offering party bears the burden of proving the requisites, especially the grounds in (c).

Landmark Supreme Court Doctrines

As of the June 30, 2025 cut-off, no Supreme Court decision has interpreted Section 18 of A.M. No. 25-02-17-SC. Because Section 18 adopts verbatim the language of Rule 23, Section 4 of the 2019 Amended Rules of Civil Procedure (Use of Depositions), the following established doctrines from main opinions on depositions and substitute testimony apply by strong analogy:

Prior notice and meaningful opportunity to cross-examine are indispensable due-process requirements; evidence taken without them cannot be used against the deprived party.
The offering party must strictly prove unavailability; mere physical absence from the Philippines is insufficient if that party procured or caused it.
Courts retain discretion on “exceptional circumstances” but must balance efficiency against the strong policy favoring live testimony in open court.
Separate authentication rules (Rule 132, Sections 24–25, as amended) continue to apply to documentary or public-record components of the evidence taken abroad.

Key Exceptions, Qualifications, and Distinctions

Strict limitation on “any purpose” use — Only (b) (party/officer evidence) or (c) (court-determined unavailability/exceptional circumstances) allow broad use; everything else is impeachment-only under (a).
Notice is jurisdictional for use against a party — Absence of notice or representation bars use against that party even if the evidence is otherwise competent.
Preference for live testimony — Ground (c)(v) is narrowly construed; convenience alone does not suffice.
Distinctions from related concepts:
- Different from foreign public/official documents (governed by Rule 132, Secs. 24–25 + Apostille where applicable).
- Different from depositions taken abroad under Rule 23/24 (available for non-Convention states).
- Different from criminal cases (governed by mutual legal assistance treaties or other mechanisms, not this Rule).
(d) prevents cherry-picking — Adverse party has an absolute right to completeness of relevant portions.
Still fully subject to the Revised Rules on Evidence — Section 18 is an additional procedural layer; it does not create a new hearsay exception or override privileges (see Sec. 2(s) of the Rules).

How This Topic Appears in Bar Essay Questions

Examiners typically give a fact pattern involving a civil/commercial case with a witness, documents, or objects located in a Hague Convention contracting state. Common asks include: May the evidence taken abroad be used? For what purpose? What objections may be raised? Draft a motion or opposition.

Common mistakes:

Treating foreign-taken evidence as automatically usable for any purpose.
Ignoring the notice/representation requirement.
Confusing this Rule with authentication of foreign public documents or with criminal evidence rules.
Forgetting to apply the five specific grounds in (c) or the completeness rule in (d).

Winning answer structure:

Cite A.M. No. 25-02-17-SC, Section 18 as the governing provision.
Check the due-process prerequisite (notice/presence/representation).
Match the facts to (a), (b), (c), or (d).
Apply the specific ground(s) in (c) if “any purpose” use is claimed.
Note that the evidence must still pass all other Rules of Evidence filters.
Conclude with the permissible scope of use and any remaining objections.

Practical Application Tips or Memory Aids

Mnemonic for the five grounds in (c)(i)–(v): D.O.U.S.E.
Dead
Out of the Philippines (not procured by offeror)
Unable (age, sickness, infirmity, imprisonment)
Subpoena (unable to procure attendance)
Exceptional circumstances (interest of justice + live-testimony preference)

Quick Comparison Table

Avenue	Scope of Use	Key Requirement	Typical Bar Application
(a)	Impeachment only	Person examined testifies at trial	Contradict own witness
(b)	Any purpose	Examined is party or its officer/agent	Use against corporate party
(c)	Any purpose	Court finds one of 5 grounds	Unavailable witness scenarios
(d)	Completeness	Partial offer made	Prevent selective introduction

Essay drafting tip: Always open with “Under Section 18 of A.M. No. 25-02-17-SC…” then quote or paraphrase the controlling phrase before applying element-by-element to the facts. This demonstrates precise codal mastery.

Key Takeaways

Section 18 applies only to evidence taken pursuant to Letters of Request under A.M. No. 25-02-17-SC in civil or commercial matters where the Hague Evidence Convention is in force between the Philippines and the Requested State.
Notice or presence/representation is an absolute prerequisite for use against any party.
Use is not automatic for any purpose; it is strictly limited to (a) impeachment, (b) party/officer evidence, or (c) court-determined unavailability/exceptional circumstances.
The five grounds in (c) must be proven by the offering party; the court exercises discretion especially on exceptional circumstances.
The evidence must still be admissible under the Revised Rules on Evidence; Section 18 is an additional procedural gateway, not a substantive admissibility rule.
The completeness rule in (d) protects the adverse party against selective presentation.
Master the exact parallel with Rule 23, Section 4 (depositions) — this is the fastest way to internalize the provision for essay writing.
For non-Convention states, fall back to ordinary deposition rules under the Rules of Court.

Internalize these elements and you will confidently handle any essay on the use of evidence taken abroad.
