Labor courts cannot invent filing requirements in social security claims
Individual social security disputes. Labor courts lack authority to require the plaintiff, as a condition for admitting the claim, to submit the evidence they deem effective to prove its claims, under article 899-C, section VIII, of the Federal Labor Law.
Official heading (Spanish): CONFLICTOS INDIVIDUALES DE SEGURIDAD SOCIAL. LOS TRIBUNALES LABORALES CARECEN DE ATRIBUCIONES PARA EXIGIR A LA PARTE ACTORA, COMO REQUISITO DE PROCEDIBILIDAD DE LA DEMANDA, LAS PRUEBAS QUE AQUÉLLOS CONSIDEREN EFICACES PARA ACREDITAR SUS PRETENSIONES, CONFORME AL ARTÍCULO 899-C, FRACCIÓN VIII, DE LA LEY FEDERAL DEL TRABAJO.
The ruling
Foreign workers sought the return of funds in their individual retirement accounts, claiming they had left Mexico permanently. One Collegiate Circuit Court required legalized, translated documents proving it; another did not. The Regional Plenary Court ruled, in binding precedent (jurisprudencia), that article 899-C, section VIII, of the Federal Labor Law lets plaintiffs offer evidence but does not allow courts to impose filing requirements not set by law.
Our take
This binding precedent separates two things some courts were blending: what it takes to have a claim admitted and what it takes to win it. A judge cannot reject a filing because, in the judge's view, suitable evidence is missing; that assessment belongs in the judgment. For pension fund managers, IMSS and employer defendants, the message is clear: the defense is no longer won at admission, but on the merits. Prepare evidentiary objections and burden-of-proof arguments from the answer, since the plaintiff still has to prove permanent departure from Mexico.
What to do
- Do not rely on the court rejecting the claim for missing documents; build merits arguments.
- Challenge, from the answer onward, the suitability of evidence about permanent departure from Mexico.
- Review pending claims where the plaintiff was ordered to meet requirements not set by law.
