(b)the requirement is imposed for any of the purposes mentioned in paragraph (2),
it shall be the duty of the relevant appropriate authority to secure that the required access is allowed to the nominated person.
(2) Those purposes are—

(b)there are reasonable grounds for not allowing that person to have the required access at the time at which that person seeks to have it,
the obligation to secure that the required access is allowed shall have effect as an obligation to secure that the access is allowed to that person at the earliest practicable time after there cease to be any such grounds as that person may specify.
(5) The provisions of this regulation are in addition to, and without prejudice to—
(a)the rights of entry, search and seizure that are or may be conferred on—

(a)the relevant appropriate authority, and
(b)any person previously appointed to carry out the investigation,
such directions as it considers appropriate for the purpose of giving effect to the new determination.

32.—(1) No person shall be appointed to carry out an investigation under regulations 38 (investigation by a police force at the request of the relevant appropriate authority) to 41(investigations managed by the IPCC)—
(a)unless that person has an appropriate level of knowledge, skills and experience to plan and conduct the investigation and to manage the resources that will be required during that process;
(b)if that person has any social, financial or other connection, whether or not within the work environment, with the person whose conduct is being investigated which could, on an objective appraisal of the material facts, give rise to a legitimate fear as to whether that investigation can be carried out impartially;

35.—(1) If, following a determination under regulations 22 (duties of the IPCC on references under regulation 21), 24 (duties of the IPCC on references under regulation 23) and 28 (duties of the IPCC on reference under regulation 27), it appears at any time to the IPCC (whether on an application by the relevant appropriate authority or otherwise) that a complaint or matter that is being investigated—
(a)by the relevant appropriate authority on its own behalf, or
(b)under the supervision or management of the IPCC,
is of a description of complaint or matter specified in paragraph (5), the IPCC may by order require the discontinuance of the investigation.

(c)one which is repetitious, as defined in paragraph (6); or
(d)one which the IPCC otherwise considers is such as to make it not reasonably practicable to proceed with the investigation.
(6) A complaint is repetitious only if—
(a)it is substantially the same as a previous complaint (whether made by or on behalf of the same or a different complainant), or it concerns substantially the same conduct as previous conduct matter;
(b)it contains no fresh allegation which significantly affects the account of the conduct complained of;
(c)no fresh evidence, being evidence which was not reasonably available at the time the previous complaint was made, is tendered in support of it; and

(a)a copy of the complaint, and
(b)a memorandum from the relevant appropriate authority containing a summary of the investigation undertaken so far and explaining the reasons for the application to discontinue the investigation.

(b)the complaint is currently subject to an appeal to the IPCC under regulation 70; and
(c)the relevant appropriate authority has notified the IPCC under paragraph (4)(b) that it has determined that the complaint is not to be treated as a recordable conduct matter,
the IPCC shall consider whether it is in the public interest for that determination to be reversed, and if so it shall instruct the relevant appropriate authority to reverse the decision.
(9) Where a complainant indicates the wish to withdraw the complaint or the wish that no further steps are to be taken in consequence of the complaint, but the complainant fails to provide a notification to that effect in writing signed by or on behalf of the complainant, then—
