Section 15.15. Voluntary admissions; suitability

(a)  In order for a person to be suitable for admission to a school as
  a voluntary resident, or for  conversion  to  such  status  he  must  be
  notified of and have the ability to understand the following:
    1. that the school to which he is requesting admission is a school for
  the mentally retarded.
    2. that he is making an application for admission.
    3.  the  nature  of  the voluntary status and the provisions governing
  release or conversion to involuntary status.
    (b) The department shall have  the  power  to  examine  the  residents
  admitted  pursuant  to  this section and determine if they belong to the
  voluntary class. If it be determined that  any  such  patient  does  not
  belong  to  the  voluntary class, the department shall determine whether
  the  resident  shall  be  discharged  or  whether  procedures  shall  be
  commenced  for  the  admission  of such resident to a school pursuant to
  other sections of this article. The decision of the department shall  be
  forthwith  complied with by the director or person in charge of any such
  school. Any failure to conform to the requirements of this section shall
  be  considered  a  sufficient  cause  for  revocation  of  an  operating
  certificate theretofore issued to a school.
