Code C and interview defects: match breach to consequence

PACE Code C governs relevant detention, treatment and questioning safeguards in England and Wales. The version applicable at the legal date of this chapter is Code C 2023, operative from 20 December 2023. Its commencement provision applies it to people in police detention after midnight on that date, including detention which began earlier. Other PACE Codes govern matters such as audio recording; do not assume every recording requirement is located in Code C.

A Code requirement and a statutory exclusion test are not synonyms. PACE s 67(11) requires a relevant Code provision to be taken into account in determining a question before the court. That makes an applicable breach significant evidence, not an automatic exclusion rule and not something the court can simply ignore. Identify the requirement, the breach, its practical effect and the correct legal consequence.

Threats, aggression or bullying. Serious treatment may amount to oppression; the same facts may engage s 76(2)(b). Less serious impropriety may still affect s 78 or weight. State what was said or done rather than treating the description “aggressive interview” as a finding under either limb.

Fatigue, illness or impaired fitness. Under Code C 12.2, in any 24-hour period the ordinary safeguard is a continuous rest period of at least eight hours, free from questioning, investigative travel and interruption. Under 12.2(a), reasonable grounds may justify delay or interruption where otherwise there would be a risk of harm to people or serious property loss or damage, unnecessary delay to release, or prejudice to the investigation. Paragraph 12.2(b) covers a request by the detainee, appropriate adult or legal representative; 12.2(c) covers necessary detention-review duties or health-care action. If rest is interrupted under (a), a fresh period is required; interruptions under (b)–(c) do not require one. For a person arrested at the station after attending voluntarily, the 24 hours run from arrest, not arrival. Check the actual reason and record, rather than assuming every interruption has the same effect. Code C 12.3 and Annex G address interview fitness and health-related risk. For s 76(2)(b), identify the questioning, inducement or omission, the suspect’s condition, likely unreliability and causation. A fitness or rest defect can also support a separate fairness argument.

Denial or delay of legal advice. Code C 6.5–6.6 and Annex B define the exceptions and authorisations concerning delayed advice and interviewing a person who has requested advice before receiving it. A right to legal advice is not a right the interviewing officer may set aside simply to obtain an early admission. Equally, do not call an interview unlawful without checking the applicable exception. An unjustified interview after a request is a serious procedural defect, but it does not automatically establish oppression or decide s 76(2)(b). Connect the lost safeguard to reliability and, separately, to the fairness of admitting the evidence.

Missing appropriate adult. An appropriate adult is a safeguard for a juvenile or vulnerable person: the adult supports understanding and communication, advises and assists, and observes whether the interview is conducted properly and fairly. The role is distinct from that of the solicitor; one is not a routine substitute for the other. Code C 1.5 requires someone who appears under 18 to be treated as a juvenile unless there is clear evidence that they are older. Vulnerability under 1.13(d) concerns specified risks arising from a mental health condition or mental disorder, including difficulties in understanding or communicating and susceptibility to unreliable or self-incriminating answers. Under 1.4, reason to suspect vulnerability must be acted on unless clear evidence dispels that suspicion; a diagnostic label is not the whole test. Code C 11.15 generally prohibits interviewing juveniles and vulnerable people about suspected offending without an appropriate adult, subject to its specified exceptions and the urgent safeguards in 11.18–11.20. Absence of the adult can form part of the s 76(2)(b) analysis, support s 78 and affect weight. None of those consequences should be asserted without applying its own test. (Code C 1.4–1.7A, 1.13(d), 11.15–11.20.)

Separate PACE s 77 caution ruleGlossary termSection 77 warning. This concerns reliance on an admitted confession, not a fourth exclusion gateway. Section 77 retains the historical statutory expression “mentally handicapped”. Its narrow definition means arrested or incomplete development of mind including significant impairment of intelligence and social functioning. Use that statutory definition for this rule, without treating its terminology as modern clinical language.

The conditions are cumulative: the case against the accused depends wholly or substantially on the accused’s confession; the court is satisfied that the accused meets s 77(3)’s definition; and the confession was not made in the presence of an independent person. That expression excludes a police officer and a person employed for, or engaged on, police purposes. Where those conditions are met in a jury trial, the judge shall warn of the special need for caution before convicting in reliance on the confession and explain why. A summary court, and a Crown Court trying the case without a jury, must itself treat the case as requiring special caution. (PACE s 77(1)–(3).)

Code C vulnerability is wider than s 77’s definition. An absent appropriate adult does not automatically establish all three statutory conditions. Conversely, “independent person” is not simply another name for “appropriate adult”. Test the presence and independence required by s 77 separately from compliance with the Code. Sections 76 and 78 remain the prior admissibility controls.

Defective caution, recording or explanation of the allegation. Identify the precise applicable Code provision. For example, Code C 10 concerns cautions and 11.1A addresses sufficient information about the suspected offence before interview; Codes E and F contain recording requirements. Explain how the identified defect affects understanding, the account’s reliability or the ability to challenge the interview. Select s 76, s 78, a direction, reduced weight or a justified combination. A demand for disclosure and an application to exclude serve different purposes.
