Comparative Analysis of Disability Laws [PDF ebook] 

The purpose of this book is to help the National Council on Disability (NCD), and others, better understand how the Convention on the Rights of Persons with Disabilities, if ratified by the United States, might impact U.S. disability laws by examining the degree to which U.S. law is consistent with the CRPD. The book endeavors to analyze the issue in the way a treaty monitoring body would – to see if any area within federal law contravenes the Convention and/or whether there are gaps where legislation or practice might be introduced or reformed to ensure compliance. This book also identifies several CRPD articles that illustrate significant gaps between United States disability laws and the Convention.
