CHAPTER XXIIICourt PrecedentIn Mexico, the judicial branch is responsible for the interpretation and harmonization ofthe laws. Through this interpretation process, the judicial branch establishes court precedent,which is binding if certain requirements are met.Binding court precedent can be formed in one of three ways in Mexico: by confirmation, byunification of interpretations, or by unconstitutionality actions and constitutional disputes.3671. Court Precedent by ConfirmationCourt precedent by confirmation is formed when the contents of judgments on severaldifferent cases are similar. There must be similarity in the interpretation adopted inresolving such judgments in order for this interpretation to become binding and consideredcourt precedent. 1In order to become court precedent by confirmation, essentially three requirementsmust be met: 2a) The case in question must turn on decisions by the Supreme Court of Justice ofthe Nation based on interpretation of the law, ruling in plenary session or in Chambers,or by the Collegiate Circuit Courts in matters of their exclusive jurisdiction;b) The interpretation must be upheld in five judgments, uninterrupted by a contraryjudgment;c) Such judgments must be adopted by a vote of eight in the case of a plenary judgmentor four in the case of a judgment in chambers. The judgment further mustbe adopted unanimously in the case of a judgment of the Collegiate Circuit Courts.__________1Supreme Court of Justice of the Nation, La jurisprudencia: su integración (Court Precedent: its Formation), Mexico,2 nd Ed., 2005, p. 25.2This is seen in Articles 192 and 193 of the Amparo Law.
