Worked solution
### Part (a) Model Answer
The Police and Criminal Evidence Act 1984 (PACE), together with its accompanying Codes of Practice, establishes and regulates the core investigative powers of the police.
Stop and Search (s1 PACE 1984 & Code A):
- Under Section 1 of PACE 1984, a police constable may stop and search any person or vehicle in a public place, or a place to which the public has access, if the officer has reasonable grounds for suspecting that they will find stolen goods, prohibited articles (offensive weapons, bladed articles), or items made or adapted for use in criminal damage/theft.
- Reasonable Suspicion: Code of Practice A specifies that reasonable suspicion must be based on objective factors, such as reliable intelligence or specific observations of behaviour, and cannot be based on personal stereotypes, age, race, or appearance.
- Procedural Requirements (s2 PACE / GOWISELY): Before the search takes place, the officer must inform the suspect of their Grounds, the Object of the search, Warrant card (if in plain clothes), Identity of the officer, Station to which attached, Entitlement to a copy of the search record, Legal power used, and that they are being detained for the purpose of a search.
- In public, the search is limited to the removal of outer coat, jacket, and gloves (JOG).
Arrest (s24 PACE 1984 & Code G):
- Under Section 24 of PACE (as amended by the Serious Organised Crime and Police Act 2005), a police officer has the power to arrest without a warrant anyone:
1. Who is about to commit an offence, or is in the act of committing an offence.
2. Whom the officer has reasonable grounds to suspect is about to commit or is committing an offence.
3. Where an offence has been committed, anyone who is guilty or reasonably suspected of being guilty of that offence.
- Necessity Test: An arrest is only lawful if it satisfies at least one of the statutory necessity criteria under s24(5), which include:
- To enable the person's name or address to be ascertained;
- To prevent the person causing physical injury, suffering physical injury, causing loss of/damage to property, committing an offence against public decency, or causing unlawful obstruction of the highway;
- To protect a child or other vulnerable person;
- To allow the prompt and effective investigation of the offence; or
- To prevent any prosecution being hindered by the disappearance of the person.
- Under s28 PACE, the suspect must be informed that they are under arrest and the grounds for the arrest as soon as practicable, followed by the formal caution.

### Part (b) Model Answer
PACE 1984 was enacted following the Royal Commission on Criminal Procedure (1981) to replace fragmented common law rules and ensure a clear balance between the rights of the individual and the investigative powers of the state.
Statutory Safeguards for Detained Suspects (PACE & Code C):
1. The Custody Officer (s36 & s38 PACE): Suspects are booked in by an independent custody officer (at least the rank of Sergeant) who is not involved in the investigation. The custody officer decides whether there is sufficient evidence to charge or if detention without charge is justified, and maintains the official Custody Record.
2. Detention Limits and Reviews (ss41–44 PACE): A person can generally only be detained for up to 24 hours without charge. An officer of the rank of Superintendent or above can authorize an extension up to 36 hours for an indictable offence. Further extensions up to a maximum of 96 hours require a warrant from a Magistrates' Court. Regular statutory reviews of detention are conducted under s40.
3. Right to Have Someone Informed (s56 PACE): Detainees have the right to have a friend, relative, or other person told of their arrest. This can only be delayed for up to 36 hours on the authority of a Superintendent in indictable cases if there are reasonable grounds to believe it will lead to interference with evidence or alerting accomplices.
4. Right to Free Legal Advice (s58 PACE): Detainees are entitled to consult a solicitor privately at any time. Delay is only permitted under strict criteria for serious arrestable offences (up to 36 hours).
5. Vulnerable Suspects and Appropriate Adults (Code C): Juveniles (under 18) and persons who are mentally vulnerable must have an Appropriate Adult present during searches, fingerprinting, and interviews.
6. Interview Conditions and Recording (Codes C, E, F): Interviews must be audio/video recorded, conducted in clean, well-lit, heated rooms, with adequate breaks for meals and rest.
7. Exclusion of Evidence (ss76 & 78 PACE): Under s76, confessions obtained through oppression or unreliability must be excluded by the trial judge. Under s78, evidence may be excluded if its admission would have an adverse effect on the fairness of proceedings.
Evaluation of the Balance:
- Protection of Rights: The independent role of the custody officer, the strict time limits, mandatory recording of interviews, and access to free legal advice provide robust protection against physical mistreatment, forced confessions, and arbitrary indefinite detention, preventing miscarriages of justice.
- Police Effectiveness: Police retain sufficient powers to investigate serious crimes effectively through authorised extensions of detention up to 96 hours, obtaining non-intimate samples without consent (s63), and temporary delays in legal consultation in exceptional circumstances.
- Criticisms and Imbalance: In practice, suspects frequently waive their right to legal advice due to confusion or pressure. The threshold for delaying rights under s56/s58 can sometimes be applied broadly by senior officers. Vulnerable suspects may be supported by inappropriate adults who lack legal understanding.
Conclusion:
PACE 1984 generally strikes a successful and workable balance between enabling effective policing and protecting suspect rights. The codification of rights, transparency of custody records, and court oversight under ss76/78 ensure that police power is subject to strict legal boundaries.
