L16: Police Powers & Civil Liberties
Police powers of stop and search, arrest and detention balanced against civil liberties
Police Powers & Civil Liberties
Police powers of stop and search, arrest and detention balanced against civil liberties
Key Fact: The Police and Criminal Evidence Act 1984 (PACE) is the primary statute governing police powers in England and Wales, balancing effective law enforcement with the protection of individual rights
Key Fact: Stop and search under PACE section 1 requires reasonable suspicion that the person has stolen or prohibited articles; the officer must state their name, station and the grounds for the search
Key Fact: Reasonable suspicion must be based on objective factors — it cannot be based solely on a person's race, age or appearance (PACE Code A)
Key Fact: An arrest without warrant under PACE section 24 requires reasonable suspicion that the person is about to commit, is committing or has committed an offence, and the arrest must be necessary
Key Fact: The necessity criteria for arrest include: enabling the person's name or address to be ascertained, preventing disappearance, preventing harm, preventing interference with evidence and preventing obstruction of the highway
Key Fact: Upon arrest, the person must be informed of the reason for the arrest and cautioned: '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'
Key Fact: A detained person has the right to have someone informed of their arrest, the right to consult a solicitor and the right to consult the PACE codes of practice
Key Fact: A custody officer must review the detention at regular intervals; detention without charge is limited to 24 hours (extendable to 36 with superintendent authority) for indictable offences, and up to 96 hours with magistrate approval
Key Fact: The right to silence exists but is modified by the Criminal Justice and Public Order Act 1994: a court may draw adverse inferences from a defendant's silence at interview if they later rely on a fact they could reasonably have mentioned
Key Fact: Stop and search has been criticised for disproportionate use against ethnic minorities; government statistics consistently show Black people are several times more likely to be searched than White people
Key Fact: Civil liberties groups argue that police powers must be balanced against individual freedoms: arbitrary or excessive use of powers can damage police-community relations and undermine public confidence
Key Fact: Safeguards against abuse of police powers include: the requirement to record stops, the role of the custody officer, the Independent Office for Police Conduct (IOPC) and the right to challenge unlawful actions in court
📋 Key Vocabulary and Concepts
For Police Powers & Civil Liberties, you must know:
- PACE 1984: The Police and Criminal Evidence Act 1984 — the primary statute governing police powers of stop and search, arrest, detention and investigation in England and Wales
- Reasonable suspicion: An objective basis for believing a person may be involved in criminal activity, required before police can stop and search or arrest; cannot be based on race or appearance alone
- Custody officer: A designated police officer responsible for reviewing the legality and necessity of a person's detention, ensuring their rights are respected and deciding whether to charge or release
- Right to silence: The right of a suspect not to answer police questions, modified by the Criminal Justice and Public Order Act 1994 which allows courts to draw adverse inferences from silence
- Stop and search: A police power under PACE section 1 allowing an officer to stop and search a person or vehicle if they have reasonable suspicion of stolen or prohibited articles
- Civil liberties: Fundamental rights and freedoms of individuals that protect them from arbitrary or excessive use of state power, including privacy, liberty and freedom of movement
❓ Practice Questions
Q: What must a police officer do before carrying out a stop and search under PACE section 1?
Q: Explain the necessity criteria for arrest under PACE section 24.
Q: How does the Criminal Justice and Public Order Act 1994 affect the right to silence?
Q: Why has stop and search been controversial?
Q: What safeguards exist against the abuse of police powers?
✅ Answers
- The officer must have reasonable suspicion that the person possesses stolen or prohibited articles, and must inform the person of the officer's name and station, the object of the search and the grounds for it. The officer must also record the search.
- An arrest is only lawful if it is necessary for one of the statutory reasons: to ascertain the person's name or address, to prevent their disappearance, to prevent physical injury, to prevent loss or damage to property, to prevent obstruction of the highway, to protect a child or vulnerable person, or to allow the prompt and effective investigation of the offence.
- The 1994 Act allows a court or jury to draw adverse inferences from a suspect's failure to mention a fact during police questioning that they later rely on in their defence, provided it is a fact they could reasonably have been expected to mention. The right to remain silent still exists but silence may now count against the defendant.
- Stop and search has been controversial because statistics consistently show it is used disproportionately against Black and ethnic minority people, it is often perceived as discriminatory, the arrest rate from searches is very low (around 10-15%), and excessive use can damage police-community trust and cooperation.
- Safeguards include: PACE codes of practice setting out procedures officers must follow, the custody officer who reviews detention, the requirement to record all stops and searches, the right to legal advice, the Independent Office for Police Conduct (IOPC) which investigates complaints, and the ability to bring judicial review or civil claims for unlawful exercise of powers.
🎯 Exam Tips
- Always link police powers back to the PACE 1984 and cite specific sections where possible (e.g. section 1 for stop and search, section 24 for arrest)
- When evaluating police powers, present both sides: effective law enforcement versus protection of civil liberties
- Use statistical evidence on stop and search disproportionality to support arguments about civil liberties concerns
- Remember the modified right to silence — candidates often forget the 1994 Act allows adverse inferences
- When discussing detention time limits, distinguish between the 24-hour, 36-hour and 96-hour limits and who can authorise each extension

⚠️ Common Errors
✗ Saying police can stop and search anyone at any time ✓ PACE section 1 requires reasonable suspicion based on objective grounds; random or blanket searches without suspicion are generally unlawful except under specific terrorism legislation
✗ Confusing the right to silence with an absolute right that has no consequences ✓ The right to silence still exists but the CJPOA 1994 allows courts to draw adverse inferences from a suspect's failure to mention a fact they later rely on in court
✗ Saying a person can be held indefinitely after arrest ✓ Detention without charge is limited to 24 hours, extendable to 36 with superintendent authorisation for indictable offences, and up to 96 hours with magistrates' approval
✗ Thinking reasonable suspicion can be based on a person's appearance or race ✓ PACE Code A explicitly states that reasonable suspicion cannot be based on personal factors alone such as race, age or hairstyle; there must be objective grounds linking the person to criminal activity

Full-Mark Response
To what extent are police powers of stop and search balanced with the civil liberties of individuals? (15 marks)
Police powers of stop and search under PACE 1984 are intended to be balanced with civil liberties, but in practice the balance is frequently questioned. On one hand, PACE provides safeguards: section 1 requires reasonable suspicion based on objective grounds, officers must give their name and station and the grounds for the search, and all searches must be recorded. PACE Code A explicitly prohibits searches based on race, appearance or stereotypes. These legal protections aim to prevent arbitrary use of power. However, in practice the balance is questionable. Government statistics consistently show that Black people are around seven times more likely to be stopped and searched than White people, suggesting racial bias in the exercise of the power. The low arrest rate following searches (typically 10-15%) raises doubts about whether reasonable suspicion is being properly applied. High-profile cases and the Stephen Lawrence Inquiry have highlighted concerns about institutional racism in policing. Furthermore, section 60 searches, which allow stops without individualised suspicion in designated areas, represent a significant departure from the normal safeguards. Civil liberties groups argue that the psychological impact of being searched, especially for young people from minority communities, is significant and damages police-community relations. While PACE sets a sound legal framework, the evidence suggests the balance too often favours police powers over civil liberties in practice.
