Human Rights Law

I need a research essay on the following question:
Writing in 2008, Kayess & French noted the following: ‘
[Convention on the Rights of Persons with Disabilities] is a highwater mark not only in the
By any measure, the CRPD area of disability rights, but also in the development of international human rights law concepts and implementation measures more generally.’ (Rosemary Kayess & Phillip French, ‘Out of Darkness into Light? Introducing the Convention on the Rights of Persons with Disabilities’ (2008) 8 Human Rights Law Review 1, 33.)
In light of this statement, critically evaluate whether, and to what extent, the Convention
on the Rights of Persons with Disabilities can be considered as having developed
international human rights law concepts. In so doing, please ensure you refer to the
relevant UN documents and academic commentary.
