Labor witnesses: facts supplied by counsel's questions carry no evidentiary weight
Witness evidence in labor matters. Testimony lacks credibility as to facts whose information is supplied by the offering party in framing the questions rather than by the witnesses themselves.
Official heading (Spanish): PRUEBA TESTIMONIAL EN MATERIA LABORAL. CARECE DE VERACIDAD LO NARRADO POR LAS PERSONAS TESTIGO RESPECTO DE LOS HECHOS CUYA INFORMACIÓN ES APORTADA POR LA PARTE OFERENTE AL FORMULAR LAS INTERROGANTES Y NO POR LOS PROPIOS DECLARANTES.
The ruling
In several unfair dismissal cases, employer counsel asked questions that assumed the witnesses last saw the workers at the company. The labor authorities credited that testimony and ruled for the employers. The Collegiate Circuit Court, in binding precedent, held that testimony lacks credibility on facts supplied by the offering party's question rather than by the witness.
Our take
Witness testimony is employers' most common evidence to deny a dismissal, and this ruling targets its weakest point: the question that contains the answer. If the witness merely confirms what counsel already asserted, the court will give it no weight. For companies, the consequence is twofold. First, witness preparation should focus on having them describe what they perceived in their own words. Second, the defense should not rest on witnesses alone; attendance, access and communication records are usually stronger. As binding precedent, it governs courts in that circuit.
What to do
- Draft open questions that require the witness to narrate the facts.
- Back the defense with attendance, access and internal communication records.
- Object at the hearing to opposing questions that contain the answer.
