Adverse inference from silence: Section 34 and interview strategy

This article explains why "no comment" is not a free pass, how Section 34 of the Criminal Justice and Public Order Act 1994 fits with police station interviews, and how to document advice. It is general education for accredited representatives — not a substitute for supervision, insurer rules, or case-specific counsel advice.

1. What reps need to know in one minute

  • In criminal proceedings, silence can sometimes be used against a defendant if they rely in court on a fact they could reasonably have mentioned in interview when questioned under caution.
  • That risk is often discussed using the shorthand "Section 34" (CJPOA 1994).
  • Your job in custody is to ensure the client understands the framework, makes an informed choice, and that your advice and their decision are recorded clearly.
  • A prepared statement is a common way to put a defence "on the record" while still answering no comment to questions.

For the regulatory framework, cross-read PACE Code C and your firm's interview policy. For tactics, see also No comment strategy and Interview techniques that actually work.

2. Legal backdrop (high level)

2.1 Section 34 — the core idea

In outline, Section 34 allows a court to draw such inferences as appear proper from a defendant's failure to mention facts when questioned under caution, where they later rely on those facts in their defence in court, and where it was reasonable to mention them earlier.

The statute is dense; the Criminal Procedure Rules and judicial directions (such as those on adverse inferences) govern how juries are directed. Representatives are not expected to lecture clients on appellate case law — but you are expected to flag that silence carries risks as well as protections, and to encourage informed decisions.

2.2 Not the same as the "right to silence"

Clients still have a right to silence. Section 34 does not abolish it. It changes what may happen if they later advance a positive case at trial that they did not mention when questioned.

2.3 Special warnings (Sections 36 and 37)

Separate provisions allow special warnings about failure to account for objects, substances, marks, or presence. These are not identical to Section 34, but they are part of the same tactical landscape. If officers give such warnings, note them verbatim in your attendance note where possible.

3. Practical advice stages

3.1 Disclosure first (so far as you have it)

You cannot sensibly advise on silence vs account without knowing what the client is said to have done and what material the police have disclosed (even if summary). If disclosure is thin, say so plainly and record it.

See Reading disclosure.

3.2 Explain options in plain English

Most clients need:

  1. Full answers — highest engagement, may help if the case is weak or explanation is simple; may harm if the client is confused, tired, or the account is incomplete.
  2. No comment — protects against inconsistent answers and fishing; carries Section 34 risk if they later advance facts they could reasonably have mentioned.
  3. Prepared statement + no comment — often used to set out a core account once, then refuse cross-examination style questioning in interview.

3.3 Document the advice

Your attendance note should record, at minimum:

  • What options were explained (in substance, not a transcript of every word).
  • What the client decided.
  • Whether they understood they could seek further advice before answering.
  • Any vulnerability factors (health, age, AA present, language).

This protects the client, the firm, and you if competence or instructions are later questioned.

4. Common scenarios (illustrative)

4.1 "I'll explain everything at court"

Explain that waiting until court can carry inference risk if those facts could reasonably have been mentioned under caution. It is the client's choice — but it must be an informed choice.

4.2 Overwhelming evidence

Where evidence is genuinely strong, tactical discussions may include early admissions, credit for guilty pleas, or focusing on mitigation. That is solicitor-led strategic territory — stay within your accreditation and supervision.

4.3 Vulnerable clients

If the client may not fully understand the caution or the consequences of silence, consider fitness for interview, appropriate adults, and whether interview should be delayed. A "no comment" interview conducted when the client cannot follow questions is a professional risk for everyone involved.
