Witness Intimidation Defence

Witness-intimidation allegations require careful separation of ordinary or legitimate contact from conduct intended to interfere with an investigation or proceedings. The identity and status of the witness, the defendant’s knowledge and the purpose of the alleged conduct are central.

KEY ANSWER

The position in brief

Section 51 Criminal Justice and Public Order Act 1994 creates offences involving intimidation of a person whom the defendant knows or believes is assisting an investigation, is a witness or potential witness, or is a juror or potential juror, where the conduct is intended to obstruct, pervert or interfere with the investigation or course of justice.

The section also covers specified retaliatory harm or threats because a person has assisted an investigation, given evidence or acted as a juror.

Legal issues

The prosecution must prove the statutory status or believed status of the person, the intimidating or harmful act or threat, and the required purpose or retaliatory reason. Context and intention are therefore critical.

Separate offences such as perverting the course of justice, harassment, threats or contempt issues may overlap depending on the facts.

Evidence that matters

Evidence often includes messages, calls, social-media material, CCTV, body-worn video, witness accounts, bail conditions, location data and the chronology of the underlying case.

Reasonable lines of enquiry

Enquiries may include obtaining complete communication threads, proving who initiated contact, checking location/CCTV evidence, reviewing the exact bail or no-contact terms and identifying legitimate reasons for contact where relevant.

What happens next

Witness-intimidation allegations are treated seriously because of their potential impact on the administration of justice. They may arise during an existing police investigation or court case and can result in separate arrest, charge and bail consequences.

Immediate steps

Do not make further contact with the witness or complainant without legal advice, particularly where bail conditions apply. Preserve all messages, call logs and surrounding context rather than deleting them.

What should you send us?

Send the allegation/charge, underlying case details, bail conditions, messages/call logs, CCTV or social-media evidence, chronology and next date.

FREQUENTLY ASKED QUESTIONS

Questions about this issue

Is any contact with a prosecution witness witness intimidation?

No. The prosecution must prove the statutory elements, including intimidating conduct and the required intention. However, contact may breach bail conditions or create other risks even where section 51 is not made out.

Can indirect contact count?

Potentially. The statute is not limited to conduct carried out face-to-face and can apply where acts or threats are communicated indirectly, depending on the facts.

Can the defence interview a prosecution witness?

There are circumstances in which defence representatives may properly seek to interview a prosecution witness, but requests should be made through the proper route and no undue pressure must be applied. CPS guidance recommends a written audit trail.
