This article is the result of the research project Convention on the Rights
of Persons with Disabilities a new paradigm for protection, which makes
a discussion of this Convention from four perspectives, we consider the
most relevant as a starting point of this international instrument in the
field of United Nations. The first is the study of the legal background of the
Convention, the second is the comparison of the Convention with other
instruments of Soft Law on disability, the third section is on a major route
for comparison between the Convention and other treaties of universal human
rights system, the latter perspective and perhaps most important, the
new emphasis on the Convention, addressed obliquely or less considered
by other international instruments.
