About this topic

PACE Code C is consistently the largest single area in the NPPF Step 2 exam. It governs the detention, treatment and questioning of suspects, and questions test precise time limits, rights and who must authorise each step.

Expect detention clocks and reviews, the appropriate adult, the right to legal advice and to have someone informed, cautions, and the December 2023 revisions to Code C.

Key legislation and cases

  • Police and Criminal Evidence Act 1984, ss.37-44 and 56-58
  • PACE Code C (2023)

Worked question 1 of 2Standard

DC Marsh arrests a woman for fraud at 09:15. She arrives at the custody suite at 09:45 where detention is authorised. At 09:30 the following day the IO requests more time but no superintendent is available until 10:00. What is the correct position?

  1. AThe suspect must be released immediately as the 24-hour period expires at 09:15
  2. BThe suspect must be released at 09:45 unless a superintendent authorises an extension before then
  3. CThe superintendent can authorise the extension at 10:00 as this is within a reasonable time
  4. DThe custody officer can hold the suspect until the superintendent is available
Show answer and explanation
Answer: B

The 24-hour clock runs from the relevant time - which is the time of arrival and authorisation at the station, not the time of arrest. Detention was authorised at 09:45 so the 24-hour period expires at 09:45 the following day. A s.42 superintendent authorisation must be obtained before that point - it cannot be applied retrospectively. If no authorisation is obtained before 09:45 the suspect must be released.

s.41 PACE 1984; s.42 PACE 1984
s.41(1): a person shall not be kept in police detention for more than 24 hours without being charged. s.41(2): the relevant time is the time of arrival at the first police station to which the person is taken after arrest.
  • A: The 24-hour period runs from the relevant time - arrival and authorisation at the station - not from the time of arrest. The relevant time here is 09:45 not 09:15.
  • C: The superintendent must authorise BEFORE the 24-hour period expires. An authorisation at 10:00 would be 15 minutes after the clock has run out and would be unlawful.
  • D: There is no power for a custody officer to hold a suspect beyond the 24-hour limit simply because a superintendent is unavailable. The suspect must be released.
Worked question 2 of 2Standard

Chloe aged 15 is arrested for assault. Her father is three hours away. Her mother cannot be contacted. A family friend aged 30 volunteers to act as appropriate adult. The custody officer considers whether to proceed. Which is correct?

  1. AThe family friend can act immediately as she is over 18 and known to Chloe
  2. BThe custody officer must wait for the father regardless of the delay
  3. CThe family friend may act under category (iii) of Code C but only after reasonable attempts to contact a parent or social worker have failed
  4. DA social worker must be called before any other category of appropriate adult can be used
Show answer and explanation
Answer: C

Code C para 1.7 sets out a hierarchy for the appropriate adult role for juveniles: (i) parent or guardian; (ii) social worker; (iii) other responsible adult aged 18+. The categories are applied in order. A family friend falls within category (iii) but can only be used where categories (i) and (ii) have genuinely failed or are unavailable within a reasonable time. The custody officer should make reasonable attempts to contact the mother and consider a social worker before proceeding with the friend.

Code C para 1.7
Code C 1.7: appropriate adult for a juvenile means (i) parent or guardian; (ii) social worker of a local authority; (iii) failing these, some other responsible adult aged 18 or over who is not a police officer or employed by the police.
  • A: Being over 18 and known to the juvenile does not automatically qualify someone as an appropriate adult. The Code C hierarchy must be followed and category (iii) is a last resort.
  • B: There is no rule requiring indefinite waiting for a specific parent. Where a parent is genuinely unavailable within a reasonable time the custody officer can move to the next category.
  • D: A social worker is category (ii) and should be considered, but the Code C does not require a social worker to be called in all cases - it requires the hierarchy to be worked through in order.
