SUBJECT: The Rule on ‘Technical Rules of Evidence’ in the NLRC

I. Introduction

This memorandum exhaustively examines the application of the rule on technical rules of evidence in proceedings before the National Labor Relations Commission (NLRC) and its Labor Arbiters. The central principle is that technical rules of evidence, as strictly applied in judicial courts, are not binding in labor proceedings. This doctrine is rooted in the constitutional mandate to afford full protection to labor and the state policy to ensure the speedy administration of justice. The memorandum will trace the legal basis, scope, limitations, and practical application of this rule, providing a comprehensive guide for practitioners.

II. Legal Basis and Constitutional Foundation

The primary legal foundation is found in Article 221 of the Labor Code of the Philippines (Presidential Decree No. 442, as amended), which explicitly governs proceedings before the NLRC and its Labor Arbiters. It states: “In any proceeding before the Commission or any of the Labor Arbiters, the rules of evidence prevailing in courts of law or equity shall not be controlling and it is the spirit and intention of this Code that the Commission and its members and the Labor Arbiters shall use every and all reasonable means to ascertain the facts in each case speedily and objectively and without regard to technicalities of law or procedure, all in the interest of due process.”
This statutory provision is reinforced by the constitutional principles under Section 3, Article XIII of the 1987 Constitution, which mandates the State to afford full protection to labor. The Supreme Court has consistently held that this policy justifies the relaxation of technical rules of procedure and evidence in labor cases to serve the overriding demands of substantial justice.

III. Definition and Scope of ‘Technical Rules of Evidence’

Technical rules of evidence refer to the formal, detailed, and often complex rules governing the admissibility, relevance, materiality, competence, and presentation of evidence in regular courts. These include, but are not limited to, the rules on the best evidence rule, the hearsay rule, the parol evidence rule, formalities for the offer and objection of evidence, and stringent authentication requirements for documents.
In the NLRC, the scope of this relaxation is broad. The Commission and its Labor Arbiters are directed to adopt a liberal attitude towards the admissibility of evidence. This means accepting evidence that would normally be excluded in court, such as affidavits, position papers, unauthenticated documents, and hearsay statements, provided they are relevant to the issues at hand. The focus shifts from admissibility to the weight of the evidence.

IV. The Guiding Principle: Substantial Evidence

The standard of proof in labor cases is substantial evidence. This is defined as such relevant evidence as a reasonable mind might accept as adequate to support a conclusion. It is more than a mere scintilla but less than preponderance of evidence. The relaxation of technical rules is the means to achieve the end of gathering all possible evidence to determine whether substantial evidence exists to support a claim or defense. The Labor Arbiter and the NLRC are tasked with evaluating all evidence presented, regardless of technical infirmities, and assigning to it the probative value it deserves based on the circumstances of the case.

V. Limitations and the Requirement of Due Process

The dispensation from technical rules of evidence is not a license for arbitrariness. It is not absolute and is bounded by the fundamental requirement of due process. The core elements of due process in labor proceedings are: (1) the parties must be given the opportunity to be heard; and (2) judgment must be rendered based on evidence presented, or at least offered, in a proceeding where the parties are given a chance to be heard.
Consequently, evidence that is utterly irrelevant, immaterial, or illegally obtained may still be excluded. Furthermore, while the rules on admissibility are relaxed, the basic rules on fairness and the right to confront witnesses, though not in the strict judicial sense, must be observed. A party cannot be convicted based solely on evidence they had no opportunity to examine or rebut.

VI. Practical Application in NLRC Proceedings

In practice, this rule manifests in several ways:

Affidavits and Position Papers: These are the primary vehicles for presenting evidence. Witnesses are not routinely called to testify in open court; their sworn statements in affidavits attached to position papers are admitted and given weight.

Documentary Evidence: Photocopies, facsimiles, or printouts of documents (e.g., pay slips, company memoranda, text message logs) are commonly admitted without strict compliance with the best evidence rule or authentication rules, unless their genuineness is specifically challenged in a way that casts serious doubt.

Hearsay Evidence: Hearsay statements contained in affidavits or documents are admitted. However, being hearsay affects the weight, not the admissibility, of such evidence. Corroborated hearsay may be given probative value.

Objections: While parties may object to evidence, Labor Arbiters often note the objection but still admit the evidence “for whatever it may be worth,” leaving the determination of its weight for the final decision.

Ex-Parte Investigations: Labor Arbiters may, on their own initiative, conduct ex-parte investigations or require the submission of additional documents to clarify factual issues.

VII. Comparative Analysis: Judicial Courts vs. NLRC

The following table contrasts the treatment of evidence in judicial courts and the NLRC:

Aspect of Evidence	Judicial Courts (Under Rules of Court)	NLRC / Labor Arbiters (Under Labor Code & NLRC Rules)
Governing Principle	Strict adherence to technical rules of evidence to ensure reliability and fairness.	Liberal application; technical rules are not controlling. Ascertainment of facts speedily is paramount.
Standard of Proof	Preponderance of evidence (in civil cases), proof beyond reasonable doubt (in criminal cases).	Substantial evidence.
Primary Mode of Presentation	Formal offer of evidence after trial, with witness examination (direct, cross, re-direct).	Submission of affidavits, position papers, and documents. Hearing, if held, is often summary.
Admissibility of Hearsay	Generally inadmissible, subject to numerous exceptions.	Admissible. Hearsay rule is not strictly applied.
Application of Best Evidence Rule	Strictly applied; requires original document for proof of content.	Not strictly applied; duplicates and photocopies are routinely admitted.
Authentication of Documents	Required before a private document can be received as evidence.	Often relaxed; documents are admitted subject to challenge on their genuineness.
Role of the Trier of Fact	Passive umpire; rules on objections based on technical rules.	Active investigator; uses reasonable means to ascertain facts and may request additional evidence.
Formal Offer of Evidence	Required; evidence not formally offered is not considered.	Not required in the same technical sense. Evidence attached to pleadings/position papers is considered.

VIII. Relevant Jurisprudence

The Supreme Court has consistently upheld this principle:

In Manggagawa ng Komunikasyon sa Pilipinas v. NLRC, the Court emphasized that technical rules are not binding and the Labor Arbiter should have admitted the union’s position paper even if filed late, in the interest of substantial justice.

In Alvarez v. Court of Appeals, the Court held that the NLRC correctly considered the affidavits of witnesses even if they were not cross-examined, as the rules of procedure and evidence in labor cases are liberal.

In Perez v. PT&T, the Court reiterated that the NLRC is not precluded from accepting and evaluating evidence submitted on appeal if it would serve the interests of justice, underscoring its investigative and non-adversarial nature.

However, in G & M (Phils.), Inc. v. Cruz, the Court clarified that while technical rules are relaxed, the evidence must still be substantial. Decisions cannot be based on mere speculation, surmises, or conjectures.

IX. Procedural Implications for Practitioners

For practitioners, this rule necessitates a strategic shift:

For Complainants/Employees: There is greater latitude to present all available evidence, even if informally obtained or documented. The focus should be on gathering all relevant documents, sworn statements, and other proofs, without excessive concern for formal technicalities.

For Respondents/Employers: Objections based purely on technical grounds (e.g., “hearsay,” “not the best evidence”) are likely to be overruled. The effective strategy is to challenge the weight, credibility, and relevance of the evidence, and to present countervailing evidence. Filing a motion to strike on technical grounds alone is often futile.

For Both Parties: The emphasis must be on the substance of the evidence. Pleadings and position papers must be comprehensive and attach all supporting affidavits and documents. The narrative that establishes the relevance and credibility of the evidence is crucial.

X. Conclusion

The rule that technical rules of evidence are not binding in the NLRC is a cornerstone of Philippine labor adjudication. It is a deliberate policy choice to favor the speedy and inexpensive resolution of labor disputes, recognizing the imbalance often inherent in employer-employee relationships. This liberal approach, however, is tempered by the due process clause and the requirement of substantial evidence. While the doors to evidence are opened wide, the final decision must still rest on evidence that is credible, substantial, and relevant. Practitioners must therefore master the art of presenting and attacking the weight of evidence, rather than relying on technical objections to its admissibility.
