Res judicata has limits: it does not always bind those absent from the first case
Res judicata. It is subject to limits set out in general and particular criteria.
Official heading (Spanish): COSA JUZGADA. ENCUENTRA LÍMITES PREVISTOS EN CRITERIOS GENERALES Y PARTICULARES.
The ruling
In an agrarian case, the court rejected a claim to a better right of possession on the ground that a prior judgment had reflexive res judicata effect. On direct amparo, the Collegiate Circuit Court held that res judicata has objective and subjective limits, plus particular criteria, such as requiring that the person against whom it is raised was heard and could offer evidence in the first proceeding.
Our take
Reflexive res judicata is a tempting defense because it skips the merits. This ruling is a reminder that it is not automatic. Whoever raises it must prove, with records from the first case, identity of subject matter and that the opposing party took part in, or at least had a chance to defend itself in, that proceeding. The case is agrarian, but the reasoning applies to commercial and corporate disputes where a judgment is stretched to shareholders, successors or third parties. In our experience, this defense fails more often for lack of proof than for lack of argument.
What to do
- File a certified copy of the first case to prove parties, subject matter and opportunity to defend.
- If res judicata is raised against you, check whether you were actually heard in the prior case.
- Map related shareholders and successors before closing a dispute to gauge how far the judgment reaches.
