Medical expert report missing worker ID: when the defect can be cured
Medical expert evidence in labor proceedings. How to cure the omission of the worker's identification in the expert report.
Official heading (Spanish): PRUEBA PERICIAL MÉDICA EN EL PROCEDIMIENTO LABORAL. FORMA DE SUBSANAR LA OMISIÓN DE CITAR EN EL DICTAMEN PERICIAL RESPECTIVO LA IDENTIFICACIÓN DE LA PERSONA TRABAJADORA.
The ruling
Collegiate Circuit Courts disagreed on the effect of omitting from a medical report the worker's identification data required by article 899-E, section II, of the Federal Labor Law. The SCJN ruled, in binding precedent (jurisprudencia), that the omission is cured by the record of the worker's appearance before the court officer with official ID and a copy, and their joint appearance before the expert; otherwise, the proceeding must be redone.
Our take
In occupational risk or illness cases, the medical report often decides the outcome. The SCJN favors substance over form: an identification defect does not void the report if the file shows who was examined. For employers and IMSS as defendants, this lowers the value of a purely formal objection. The useful defense lies elsewhere: check whether the file actually records the worker's identity and, if not, request that the proceeding be redone. Challenging the expert's methodology and conclusions remains the main battlefield.
What to do
- Check whether the file contains the court officer's record identifying the examined worker.
- If that record is missing, request that the proceeding be redone under this binding precedent.
- Focus objections on the expert report's methodology and medical conclusions.
