Ancillary amparo arguments must tie into what the main amparo granted
Ancillary (adhesive) amparo. Claims raising various grounds that could each independently lead to dismissal, a finding of mootness or denial are ineffective.
Official heading (Spanish): AMPARO ADHESIVO. SON INOPERANTES LOS CONCEPTOS DE VIOLACIÓN EN LOS QUE SE PLANTEEN DIVERSOS SUPUESTOS QUE, DE FORMA AUTÓNOMA, PUDIERAN LLEVAR A SOBRESEERLO, DECLARARLO SIN MATERIA O NEGARLO.
The ruling
In a labor case, the employee won an amparo only to have certain benefits quantified. The company filed an ancillary amparo raising supporting arguments, a procedural violation and an omission in the award, none tied to that effect. The Collegiate Circuit Court held that, given the ancillary nature of this remedy (article 182, Amparo Law), those claims are ineffective and the ancillary amparo must be denied.
Our take
The ancillary amparo is how the prevailing party protects its result, and many companies use it as a catch-all. This precedent stops that: if the arguments do not bear on the effects of what the employee won, they are ineffective. The lesson is technical. Relevant procedural violations should be planned in advance and tied to the opponent's likely claims. And if a violation truly harms the company, the ancillary route may not be the right one. In our experience, fewer, better-linked arguments perform better.
What to do
- Draft ancillary amparos only with arguments tied to the potential effects of the main amparo.
- Assess whether a procedural violation harming the company calls for a main, not ancillary, amparo.
- Review the structure of pending ancillary amparos with outside counsel in light of this precedent.
