Part 2: Oversight Arrangements Section 10: Main functions of the Investigatory Powers Commissioner
This section amends the IPC’s main oversight functions.
	Section 10(2)(a) removes the IPC’s functions relating to the oversight of prevention or restriction of use of communication devices by prisoners etc., as telecommunications restriction orders are already subject to judicial approval in the county court.
	Section 10(2)(b) places certain MoD oversight functions on a formalised footing, which are currently overseen on a non- statutory footing. To achieve this, this section inserts a provision into the IPA 2016 that the IPC must keep under review (including by way of audit, inspection and investigation) compliance by any part of His Majesty’s forces, or by any part of the Ministry of Defence, with policies governing the use of surveillance and the use and conduct of covert human intelligence sources outside the UK.
	Section 10(3) inserts a provision specifying that the Prime Minister may direct the IPC to carry out additional oversight functions in respect of any public authority not mentioned in section 230(1)(a) - (c) of the IPA 2016, so far as engaging in intelligence activities.
	Section 10(4) replaces the reference to a "code of practice under Schedule 7" with a reference to a "relevant code of practice". This is then defined in a new subsection to mean a code of practice under Schedule 7 of the IPA 2016, the Police Act 1997, Regulation of Investigatory Powers Act 2000, or the Regulation of Investigatory Powers (Scotland) Act 2000. This amendment is intended to clarify the scope of "relevant errors" under the IPA 2016.
