General Principles

Concept

Labor procedure seeks a prompt and fair resolution of disputes arising from work. It is less formal than ordinary civil litigation, but informality does not dispense with proof or due process. Three connected questions guide the decision-maker: who must prove a fact, how much evidence is needed, and how the evidence may be received and assessed. (Yumang v. Network, G.R. No. 201016, 22 June 2016)¹ (Labor Code of the Philippines, provisions on proceedings before the NLRC)

Governing provisions

The Labor Code directs Labor Arbiters and the NLRC to ascertain the facts speedily and objectively, without being bound by strict technical rules of evidence. The purpose is to resolve labor disputes on their merits rather than allow procedural form to obscure the facts. The relaxation of technical rules remains subject to the parties’ right to a fair opportunity to present their positions. (Yumang v. Network)¹ (Labor Code of the Philippines, provisions on proceedings before the NLRC)

Requisites / Rules

• Burden of proof identifies the party who must establish a material claim or defense. In a termination dispute, for example, the employer bears the burden of proving a valid or authorized cause for dismissal. (Pedro v. Solis, G.R. No. 116175, 28 October 1996)²
• Quantum of evidence asks whether the proof presented is sufficient to support a factual finding. Labor adjudication applies the substantial-evidence standard: relevant evidence that a reasonable mind might accept as adequate to support a conclusion. Relaxed procedure does not permit a finding based on speculation. (Ang Tibay v. Court of Industrial Relations)
• Technical rules not binding concerns the manner of receiving and evaluating proof. A Labor Arbiter or the NLRC may look beyond formal evidentiary requirements to determine what happened, while still assessing whether the material is reliable and sufficient. (Yumang v. Network)¹

Key doctrines

These principles work together, not as substitutes for one another. A party does not meet its burden merely because technical objections to its evidence are relaxed; it must still present evidence sufficient to support its position. Conversely, procedural flexibility helps the tribunal consider material that can fairly establish the facts. (Yumang v. Network)¹ (Ang Tibay v. Court of Industrial Relations)

Fairness also governs review. As a rule, a party may not raise a new issue or theory for the first time at a late stage when the opposing party had no fair opportunity to address it below. Relaxed labor procedure is not a license to withhold an argument until appeal. (Ondevilla v. (Laguna), G.R. No. 278615, 29 June 2026)³ (Mendoza v. Rural Bank of Lucban, G.R. No. 155421, 7 July 2004)⁴

Bar tip

Keep the questions separate: identify who bears the burden, test whether the evidence meets the required quantum, then consider whether an objection rests only on a technical rule. (Pedro v. Solis)² (Yumang v. Network)¹ (Ang Tibay v. Court of Industrial Relations)
