The main task of this article is to demonstrate materialization of a new trend in international legal system concerning rights of persons with disabilities. International community seems to distance itself from a mercy-based protection of individuals with disabilities. While realizing their differences, international community has created a kind of egalitarian framework to provide these individuals with equal rights and opportunities. By providing these personswith a set of negative and positive rights, "the UN Convention on Rights of Persons" with Disabilities represents what I call it "change of discourse". Yet, in order to shed some lights on the content of this new humanistic approach, conceptual analysis of the term disability, as well as theoretical foundation of their equal treatment are in need of serious discussion, which this article undertake the task.
