States must comply with a number of basic principles, including non-discrimination. The aim of this principle is to guarantee equal treatment of all persons regardless of their race, gender, nationality, social condition, sexual orientation, gender identity, functional diversity, age, or ethnic, cultural, religious or any other background.
International law requires that any distinction must be objective and reasonable; pursue a legal objective and there has to be a relationship of proportionality between the means employed and the ends. Otherwise, the distinction in treatment will constitute discrimination. However, many communities still face a less favorable treatment and more obstacles in the exercise of their rights and freedoms solely based on their specific conditions or characteristics, thus constituting an illegal act of discrimination.
