…any distinction, exclusion, restriction, or preference based on certain motives, such as race, color,

The Court reiterates that while the general obligation of Article 1(1) refers to the
State’s duty to respect and guarantee “without discrimination” the rights included in the
American Convention, Article 24 protects the right to “equal protection before the law” 91.
That is, Article 24 of the American Convention prohibits discrimination, by law or de facto,
not only with regard to the rights enshrined in said treaty, but also in regard to all laws
approved by the State and their application. In other words, if a State discriminates in the
respect for or guarantee of a right contained in the Convention, it will be failing to comply
with its obligation under in Article 1(1) and the substantive right in question. If, on the
contrary, the discrimination refers to unequal protection by domestic laws, the fact must be
analyzed in light of Article 24 of the American Convention.92

The Court has established, as has the European Human Rights Court, that
human rights treaties are living instruments, whose interpretation must go hand in hand
with evolving times and current living conditions93 This evolving interpretation is consistent
with the general rules of interpretation set forth in Article 29 of the American Convention, as
well as those established in the Vienna Convention on the Law of Treaties.94
84.
In this regard, when interpreting the words “any other social condition” of
Article 1.1 of the Convention, it is always necessary to choose the alternative that is most
favorable to the protection of the rights enshrined in said treaty, based on the principle of
the rule most favorable to the human being95
85.
According to Article 1(1) of the American Convention, the specific criteria by
virtue of which discrimination is prohibited do not constitute an exhaustive or limitative list,
but merely illustrative. Indeed, the wording of said article leaves open the criteria with the
inclusion of the term “another social condition,” allowing for the inclusion of other categories
that have not been explicitly indicated. Consequently, the Court should interpret the term
“any other social condition” of Article 1.1 of the Convention in the context of the most
