What Is an Interview Under Caution?

A thorough guide to police interviews

An interview under caution is a structured process used by police and other investigators when questioning someone they reasonably suspect may be involved in a criminal offence. It forms a key part of many investigations and is governed by statute and professional standards to protect both the integrity of evidence and the rights of the person being questioned. This article explains what an interview under caution involves, how it differs from informal conversation, the rights you have in such an interview, and what might happen afterwards, in clear and accessible terms.

1. The Legal Context and Purpose

In England and Wales, investigators often need to obtain direct information from a person suspected of involvement in an offence. To ensure fairness and legal compliance, the Police and Criminal Evidence Act 1984 (PACE) Codes of Practice set out when and how such questioning must be conducted. Under PACE Code C, questioning someone about their suspected involvement in a crime once there are reasonable grounds to suspect them amounts to an interview under caution. An interview under caution is not merely a casual conversation; it is a formal process that can produce evidence used in court and affects how the investigation proceeds.

2. What an Interview Under Caution Is

An interview under caution is defined as the formal questioning of a person regarding their involvement or suspected involvement in a criminal offence, where a caution is given at the start. The caution informs the individual of their right to remain silent and that anything they say may be used as evidence in any subsequent proceedings.

It is important to understand that:

• An interview under caution can happen whether or not a person is under arrest; it may be conducted in a police station, or occasionally elsewhere, if lawful and appropriate.
• The caution itself must be given before any substantive questioning begins.
• The interview is normally audio or video recorded to create an accurate record of what was said.

3. When and Why Interviews Under Caution Are Conducted

An interview under caution generally occurs when:

• The police (or other investigators) believe there is evidence to suggest you may have committed an offence.
• They need to hear your own account of events to decide whether to charge you, or to clarify details before making a charging decision.

You may be asked to attend voluntarily, or the interview may take place after arrest. Even if you are not under arrest, attending a voluntary interview can be significant. Not attending without good reason might lead to arrest and compulsory questioning later.

4. The Caution: What It Says and Why It Matters

Before any substantive questions are put during an interview under caution, the investigator must give the official caution, which is typically given in the following form:

“You do not have to say anything. But it may harm your defence if you do not mention when questioned something which you later rely on in court. Anything you do say may be given in evidence.”

The caution has three key effects:

1. It makes clear you have a right to remain silent.
2. It warns that silence or ‘no comment' may affect how your defence is viewed later, particularly if you later rely on facts you did not mention.
3. It informs you that anything you say can be used as evidence in subsequent proceedings.

This caution is a legal requirement under PACE and must be understood before the interview proceeds.

5. Rights During an Interview Under Caution

You have several important rights designed to ensure the interview is fair and lawful:

Right to Legal Representation

You are entitled to consult a solicitor and have them present during the interview. If you do not have your own legal representative, you can request a duty solicitor or your chosen legal adviser to attend before questioning begins.

Right to Remain Silent

You are not obliged to answer any questions, although remaining silent permanently may have implications if you later rely on facts not mentioned during the interview.

Right to Have Someone Informed

If the interview occurs at a police station, you generally have the right to have someone informed of your whereabouts.

Right to Interpreter or Communication Support

If you do not understand English or have communication needs, you may request a qualified interpreter or other assistance.

Right to Stop or Leave a Voluntary Interview

If the interview is voluntary (not under arrest), you may generally choose to leave or stop the interview at any time, although refusal to cooperate can result in arrest and compulsory questioning.

6. The Interview Process: What to Expect

Preparation and Disclosure

Before the interview, the police may provide some disclosure to your legal adviser about the nature of the allegations and the evidence they have. This helps your solicitor prepare you for the questions.

Recording and Administration

Once the caution has been given, the interview is normally audio or video recorded, creating an official record that may later be provided to your legal team or used in court.

Questioning

The interviewer will ask questions about the alleged incident or matters relevant to the offence. You can choose how to respond to each question, and your solicitor can advise you on whether and how to answer.

7. Legal and Practical Implications of the Interview

What you say during an interview under caution can have significant consequences:

• Statements made can be used in evidence in court if you are charged.
• Failing to mention important facts at the interview may lead to adverse inferences being drawn in some circumstances under the Criminal Justice and Public Order Act 1994.
• A voluntary interview is taken seriously; refusal or avoidance can prompt further action, including arrest.

Because of these implications, legal advisers often recommend obtaining expert representation before attending.

8. Possible Outcomes After an Interview

After the interview concludes, several outcomes are possible:

• No further action, where the police decide there is insufficient evidence to pursue charges.
• Released under investigation, where further enquiries continue before a charging decision is made.
• Police caution, which is a formal warning for minor offences.
• Charge and prosecution, where sufficient evidence leads to formal charges and subsequent court proceedings.

Your solicitor can explain how the interview may affect these outcomes.

9. Common Questions from our Readers

Does an interview under caution affect my criminal record?
An interview alone does not by itself create a conviction or criminal record; it is part of the investigative process. Only a conviction or certain formal cautions will be recorded on a DBS check.

Can I refuse to attend a voluntary interview?
Yes, but refusal may lead investigators to consider arrest or proceed with the investigation without your account.

Should I have a solicitor present?
Yes. A solicitor can guide you through the process, help protect your legal interests and advise on which questions to answer.

Summary

An interview under caution is a formal police or investigator questioning process used when there are reasonable grounds to suspect someone's involvement in an offence. Governed by the Police and Criminal Evidence Act (PACE) and its Codes of Practice, the process requires a caution at the outset, ensures the interview is recorded, and protects key rights such as access to legal representation and the right to remain silent. What you say during this interview can be used as evidence in court, and attending an interview without legal advice may carry risks. Understanding the procedure and your entitlements helps you engage with the process while safeguarding your legal position.
