(2) After performing the duties imposed on him by paragraph (1), the Chief Constable shall determine whether he is the appropriate authority in relation to the member of the police force against whom the complaint was made.
(3) If he determines that he is not the appropriate authority, it shall be his duty—
(a)to send the complaint or, if it was made orally, particulars of it, to the Police Authority; and
(b)to give notice that he has done so to the complainant.
(4) Nothing in this Part has effect in relation to a complaint in so far as it relates to the direction or control of the police force by the Chief Constable.
(5) If any conduct to which a complaint wholly or partly relates is or has been the subject of criminal or disciplinary proceedings, none of the provisions of this Part which relate to the recording and investigation of complaints have effect in relation to the complaint in so far as it relates to that conduct.
