The Commission may, in accordance with this Part, investigate the delivery of health services by a health service provider directly affecting the clinical management or care of clients which may not be the particular object of a complaint but which arises out of a complaint or out of more than one complaint, if it appears to the Commission that--
(a) the matter raises a significant issue of public health or safety, or
(b) the matter raises a significant question as to the appropriate care or treatment of clients, or
(c) the matter, if substantiated, would provide grounds for disciplinary action against a health practitioner or relevant health organisation.
