Individuals with a SMI (Serious Mental Illness) designation have all the rights of every other citizen plus they have additional rights. These specific additional rights are in the Arizona Revised Statues (A.R.S.) chapter 5, article 2, section 36-504 through 36-514. You can view the AHCCCS OIFA (Office of Individual and Family Affairs) explanation of this right at https://www.azahcccs.gov/AHCCCS/Downloads/YourRightsAsAnIndividualWithAnSMIDesignation.pdf
In addition the Center for Disability Law has A Self-Advocacy Guide – Your Rights as a Person with Serious Mental Illness
