Definition of disability

Are all persons with a physical, sensory, intellectual or mental/psychosocial disability covered by the relevant legislation protecting the rights of persons with disabilities?
Is the State using a “long-term” criterion when defining who is considered to be protected by the legislation and, if so, is the application of this criterion resulting in the exclusion of certain groups of persons with disabilities?
Does the State’s definition of disability/persons with disabilities reflect the social model of disability, by referring to the interaction between the impairment and the environment, or is it based on medical conditions and degree of disability, which would relate to the medical model of disability?
Does the State’s definition of disability contribute to the exclusion or segregation of people with disabilities or is otherwise inconsistent with the CRPD?
