All assistance grants shall be reconsidered as frequently as may be required by the rules of the state department.  After such further investigation as the parish may deem necessary, or the state department may require, the amount and manner of giving assistance may be changed or assistance may be entirely withdrawn if the state or parish departments find that recipient‘s circumstances have altered sufficiently to warrant the action.  The parish department may at any time cancel and revoke assistance for cause and it may for cause suspend assistance for such period as it may deem proper.  Whenever assistance is thus withdrawn, revoked, suspended or in any way changed the parish department shall at once report to the state department such decision together with the report of its investigation.  All such decisions shall be subject to review by the state department.
