Part 2: Police Complaints, Discipline and Inspection Chapter 1: Police Complaints Section 18: IPCC power to require re-investigation
Subsection (1) inserts new section 13B into the 2002 Act which enables the IPCC to re-investigate a complaint, recordable conduct matter, or DSI matter at any time if it is satisfied that there are compelling reasons to do so. This applies only to investigations that were conducted as independent or directed investigations. It will not be able to re-investigate where the original investigation was conducted by an appropriate authority.
	Such a decision can only be taken if the original investigation has concluded, with the report of that investigation submitted to the IPCC as set out in paragraphs 22(3), 24A or 22(5) of Schedule 3 to the 2002 Act.
	If the IPCC decides to re-investigate, the usual duties to notify the appropriate authority of the report (of the original investigation), and to consider criminal or disciplinary action – as set out in paragraphs 23, 24A, 27 and 28B of Schedule 3 to the 2002 Act – cease to apply (see amendments made to these paragraphs by subsections (3) to (6)).
	The IPCC is however obliged to notify the appropriate authority, complainant (if any), the person whose conduct the re-investigation concerns and any person entitled to be kept properly informed of any decision to re-investigate. Exceptions to the duty where it might, in the opinion of the IPCC, prejudice the re-investigation may be set out in regulations (see new section 13B(12)).
