Central Chambers Law
Understanding the Police and Criminal Evidence Act (PACE)

The Police and Criminal Evidence Act 1984, universally known as PACE, is one of the most important pieces of legislation in the UK's criminal justice system. It is the rulebook that governs police powers and, crucially, protects the rights of individuals who come into contact with the law. From stop and search on the street to interviews in the police station, PACE dictates what the police can and cannot do. Understanding this Act is essential, as any breach of its rules by the police can have a significant impact on the outcome of a criminal case.
At Central Chambers Law, our senior legal consultants possess an expert, in-depth knowledge of PACE and its accompanying Codes of Practice. We use this expertise every day to hold the police to account and protect our clients' rights. Our function is to ensure that the rules designed to ensure fairness are followed to the letter. We are specialists who understand that a procedural error by the police can be the key to successfully defending a case.
What is PACE?
The Police and Criminal Evidence Act 1984 (PACE) and its detailed Codes of Practice provide the core framework for police powers in England and Wales. Its primary purpose is to create a fair and balanced system that allows the police to investigate crime effectively while also safeguarding the fundamental rights and liberties of the public.
PACE covers almost every stage of the early part of a criminal investigation, including:
- Powers to stop and search individuals and vehicles.
- The procedures for arrest.
- The detention, treatment, and questioning of suspects in custody.
- The rules for conducting identification procedures.
- The methods for searching premises and seizing property.
These rules are not optional guidelines; they are legal requirements that the police must follow.
Key Provisions and Safeguards under PACE
PACE establishes a series of critical rights and protections for suspects. These safeguards are designed to prevent the abuse of power and ensure that evidence obtained by the police is fair and reliable.
Stop and Search
Police have the power to stop and search you if they have 'reasonable grounds' to suspect you are carrying illegal drugs, a weapon, stolen property, or something that could be used to commit a crime. PACE dictates that these grounds must be objective and based on intelligence or information, not on personal factors like age, race, or appearance.
Arrest
PACE sets out the specific conditions under which an arrest is lawful. An officer must have reasonable grounds to suspect a person's involvement in an offence and believe that the arrest is necessary for a specific reason, such as to ascertain their name and address or to prevent them from causing harm or obstructing justice.
Detention and Custody
Once at the police station, your detention is governed by strict rules. A 'custody officer', independent of the investigation, is responsible for your welfare and for ensuring your rights are upheld. PACE imposes strict time limits on how long you can be detained without charge.
The Right to Legal Advice
This is one of the most important safeguards under PACE. You have the absolute right to free and independent legal advice from a solicitor. The police cannot question you about an offence until you have been given the opportunity to speak with a lawyer.
Interviews Under Caution
PACE governs the entire interview process. All interviews must be recorded and conducted under caution, where you are reminded of your right to remain silent. The rules are designed to prevent oppressive or unfair questioning and to ensure that any confession is voluntary.
Consequences of a PACE Breach
When the police fail to follow the rules set out in PACE, it can have serious consequences for the prosecution's case. The courts view breaches of PACE very seriously, as they undermine the fairness of the entire justice process.
If your solicitor can prove that evidence was obtained in breach of PACE, they can make a legal argument to have that evidence excluded from the trial. For example:
- If a confession was obtained through oppression or in circumstances that make it unreliable (e.g., by denying you legal advice), it can be ruled inadmissible under Section 76 of PACE.
- If evidence was obtained unfairly (e.g., through a significant breach of the interview rules), a judge has the power to exclude it under Section 78 of PACE if its admission would have an adverse effect on the fairness of the proceedings.
A successful challenge to the evidence can sometimes lead to the entire collapse of the prosecution's case.
Why Central Chambers Law Provides the Definitive Defence
A deep, technical knowledge of PACE is a non-negotiable requirement for any expert criminal defence solicitor. Identifying breaches of the rules requires a keen eye for detail and a complete understanding of police procedure. This is not something a general lawyer can provide effectively.
Clients trust Central Chambers Law because we are masters of criminal procedure. Our reputation is built on our ability to forensically analyse every aspect of a police investigation for errors and procedural failures. Our strategic approach involves:

- Challenging the Legality of Police Actions: We are experts at assessing the lawfulness of a stop and search, an arrest, or a search of your property. If the police have overstepped their powers, we will challenge it robustly.
- Analysing Interview Recordings: We carefully review the recordings of your police interview to identify any unfair questioning, pressure, or breaches of the Codes of Practice that could render the interview inadmissible.
- Expert Legal Argument: Our experienced advocates are skilled at drafting and presenting powerful legal arguments in court to have evidence excluded. We know how to persuade a judge that a breach of PACE has made the proceedings unfair.
Our focused expertise means we are perfectly equipped to hold the police to account and ensure your case is defended on the strongest possible terms.
Protect Your Rights with Expert Legal Representation
The rules set out in PACE are your protection against the power of the state. However, these rights are only effective if you have an expert on your side who knows how to enforce them. A breach of procedure by the police could be the key to your defence.
