Amends the Mental Health and Developmental Disabilities Administrative Act. Provides that notwithstanding any other law or rule to the contrary, a State-operated developmental center funded, certified, or licensed by the Department of Human Services shall readmit, upon request, any former resident who transferred to and currently receives services at a licensed community-integrated living arrangement, if the former resident consents or if the former resident has a guardian with placement authority and that guardian consents based on a determination that the former resident's medical needs cannot be met by the program of services administered by the community-integrated living arrangement. Provides that if a State-operated developmental center is unable to readmit a former resident on account of the State-operated developmental center's planned closure or reduction in bed capacity, then the former resident may choose to be admitted to any other State-operated developmental center, subject to bed availability. Effective immediately.
