Section 29.07. Commissioner's powers over admissions to department facilities

(a)  The commissioner may by order defer admissions to any facility in
  the department when the total number of  patients  therein  exceeds  its
  capacity  to an extent which will not permit adequate care and treatment
  to be provided patients.
    (b) If the commissioner shall determine that  overcrowding  exists  in
  the   department  schools,  he  may,  within  the  amounts  appropriated
  therefor, authorize admission for care and  treatment  of  any  mentally
  retarded  person  to a designated facility approved for such purposes by
  the commissioner. The patient and any liable relatives shall  be  liable
  for  payment  of  fees  in  accordance  with article forty-three of this
  chapter.
