The commissioner may request the Attorney General to petition the Superior Court for such order as may be appropriate to enforce the provisions of this section. The commissioner’s authority shall include, but shall not be limited to, the right to initiate or otherwise take those actions necessary to assure the health, safety and welfare of any elderly person.
