(1998), these international judgments must be complied with,87 and they take on a “definitive and unappealable” nature;88 without allowing for any domestic provision or judicial criteria to be alleged to justify the noncompliance, since the international pacts obligate the State party and its norms must be complied with, in the terms of Articles 26 and 27 of the Vienna Convention on the Law of Treatises,89 also signed by the State of Mexico. 66. In this manner, the “diffused control of conformity with the Convention” implies that all of the Mexican judges and bodies linked to the administration of justice at all levels that pertain to the Judicial Powers, independent of the level of hierarchy, grade or amount of specialization, are obligated, ex oficio, to carry out an exercise of compatibility between the domestic acts and norms and the American Convention on Human Rights, its additional protocols (and other international instruments), as well as the jurisprudence of the I/A Court of H.R., forming a “block of conventionality” in the terms analyzed.90 The foregoing is due to:91 (…)it is not only the suppression or expedition of domestic legal provisions that guarantee the rights contained in the American Convention. Pursuant to the obligation established in its Article 2 thereof, the State must also develop practices leading to the effective observance of the rights and freedoms embodied in the Convention. The existence of a norm does not, in and of itself, guarantee that its application will be adequate. It is necessary that the application of the norms or their interpretation, as jurisdictional practices and expressions of the State’s public order, must be adapted to the objective sought by Article 2 of the Convention. 92 In practical terms, as the Court has already established, the interpretation of Article 13 of the Mexican Constitution must be coherent with the constitutional and the treaty-based principles of due process and access to justice contained in Article 8(1) of the American Convention and the pertinent provisions of the Mexican Constitution.
