CONCURRING OPINION OF JUDGE A.A. CANÇADO TRINDADE 1. I have concurred with my vote for the adoption, by the InterAmerican Court of Human Rights, of the instant Judgment in the case of Acosta Calderón versus Ecuador, since I agreed with its operative paragraphs and with that stated by the Court in the considerations that motivated it. What I am not satisfied with is that the Court did not issue a ruling regarding other matters set forth in the instant case, which, to my understanding, should have served as the bases for another two operative paragraphs in the instant Judgment. Thus my decision to present to the Court this Concurring Vote, in which I am obliged to inform of my reasoning, clearly different to that of the Court, regarding the matters ignored by it. 2. In the case of Suárez Rosero versus Ecuador (1997), the Inter-American Court declared the violation of Article 2 of the American Convention on Human Rights since Article 114 bis, in fine, of the Ecuadorian Criminal Code, in force at that time, robbed “a part of the prison population of a fundamental right on the basis of the crime of which it is accused,” and, hence, intrinsically injures “everyone in that category” (para. 98). The Court understood that the application of that legal stipulation had caused an “undue harm to the victim, and observed that, this law violates per se Article 2 of the American Convention, whether or not is was enforced” (para. 98). The mentioned stipulation of the Ecuadorian Criminal Code (Article 114 bis) was a violation to Article 2 of the Convention precisely because of its discriminatory nature, and specifically because it treated those accused of crimes related to drug trafficking (sanctioned by the Law on Narcotic and Psychotropic Substances) unequally before the law. 3. Despite not having been declared in that case, decided in 1997, a violation to Article 24 of the Convention, subsequently, in its historic Advisory Opinion No. 18 on the Juridical Condition and Rights of Undocumented Migrants (2003), the Court developed its jurisprudence with regard to discrimination and inequality before the law, having declared that “the principle of equality before the law, equal protection before the law and non-discrimination belongs to jus cogens, because the whole legal structure of national and international public order rests on it and it is a fundamental principle that permeates all laws. Nowadays, no legal act that is in conflict with this fundamental principle is acceptable, and discriminatory treatment of any person, owing to gender, race, color, language, religion or belief, political or other opinion, national, ethnic or social origin, nationality, age, economic situation, property, civil status, birth or any other status is unacceptable.
