It investigates how the UN Convention on the Rights of Persons with Disabilities (CRPD) is implemented by different federal systems around the world.It analyses the effects that the obligations undertaken under the CRPD have on federal governance and on the constitutional division of powers within 14 federal systems, including those in the UK, Italy, Germany, Canada, Brazil, and India. The book also considers the trends and patterns of disability rights governance in federal systems and looks at the future developments of comparative disability federalism.
