Police can no longer keep your fingerprints and DNA forever just because you were once arrested. The old blanket-retention rule was a breach of your privacy rights, and Parliament had to bring in tighter limits.
The blanket and indiscriminate regime for the retention of fingerprints, cellular samples and DNA profiles of all persons arrested for a recordable offence — including those acquitted or never charged — established by s.64(1A) PACE (as inserted by the Criminal Justice and Police Act 2001) failed to strike a fair balance under Article 8 ECHR: it was disproportionate, drew no distinction by reference to offence-type or outcome, set no time limit, and offered no realistic independent review. The Strasbourg ruling drove the legislative redesign of the regime in Chapter 1 of Part 1 of the Protection of Freedoms Act 2012, which replaced s.64 with the present ss.63D–63U scheme.
Police were never actually required to keep your DNA forever — that was just their own policy, and the Supreme Court struck it down. They must consider your privacy rights when deciding what to retain after an acquittal.
Following S and Marper, the Supreme Court read s.64(1A) compatibly with Article 8 under s.3 of the Human Rights Act 1998: the provision is permissive, not mandatory, and does not require the Commissioner to retain biometric data indefinitely in every case. The ACPO Guidelines, which provided for indefinite retention regardless of acquittal or no-charge save in narrow "exceptional case" circumstances, were therefore unlawful as incompatible with Article 8. The Court declined to grant a declaration of incompatibility under s.4 HRA because s.64(1A) itself could be read down.
Holding. Section 64(1A) is capable of being read compatibly with Article 8 ECHR; the unlawfulness lies in the ACPO Guidelines, which were quashed. No declaration of incompatibility was needed. The Court invited Parliament to legislate a Marper-compliant retention regime — which Parliament subsequently did via the Protection of Freedoms Act 2012.
Anyone questioned by police in custody is entitled to a solicitor from the very first interview. Section 58 already gives you that right in England and Wales — it's the gold standard other parts of the UK had to match.
The right of access to legal advice expressly conferred by s.58 — described in R v Samuel [1988] QB 615 as a "fundamental right of a citizen" — already gives effect in England and Wales to the Article 6(3)(c) ECHR principle later articulated by the Grand Chamber in Salduz v Turkey. Cadder confirmed that Salduz applies whenever a suspect is questioned in custody and that the English s.58 regime is in substance Salduz-compliant; the Scottish detention regime, by contrast, was not.
Holding. Article 6(3)(c) ECHR requires the accused to have access to a lawyer from the first police interview; s.58 PACE (read with Code C) already provides for this in England and Wales, and is the model against which compliant practice elsewhere is to be measured.
Whether what you said to police counts as a confession is fixed at the moment you said it. An innocent explanation stays an innocent explanation, even if hindsight later makes it look incriminating.
The definition of "confession" in s.82(1) — "any statement wholly or partly adverse to the person who made it" — operates by reference to the time the statement was made. "Adverse" means adverse at that moment, not adverse only with the benefit of hindsight at trial. A wholly exculpatory or neutral statement, judged at the time, is therefore not a "confession" within s.82(1) and so falls outside s.76, even if subsequent evidence at trial makes it damaging to its maker.
If you're tried alongside someone who confesses, the jury can use that person's guilt as evidence in your case — but they must not be told to treat what was said in the confession itself as proof against you.
Decided on the eve of s.76A's commencement, the House held that, where three defendants are tried jointly and the guilt of the principal can be proved against him from his own confession alone, a jury may use its finding of the principal's guilt as a stepping-stone in considering the case against a secondary party — provided it does not treat the contents of the confession as evidence against the secondary party. The decision sets the doctrinal context in which s.76A (inserted by s.128 CJA 2003) now operates: a co-defendant may put a defendant's confession in evidence against that defendant, subject to the same reliability safeguards as the Crown faces under s.76.
Holding. Certified questions answered in the affirmative. A jury may rely on a confession to convict its maker and then use that conviction as part of the evidence against a co-defendant on a joint enterprise count, provided proper directions are given to keep the contents of the confession out of the case against the co-defendant.
Even if the judge lets your confession into the trial, the jury must still be told: if they think it might have been beaten or bullied out of you, they have to ignore it. Your fate doesn't rest on a single ruling.
Although s.76(2) makes admissibility a matter for the judge alone (the jury cannot revisit the judge's ruling on oppression or unreliability), Article 6 ECHR requires the trial judge to direct the jury that if they conclude, despite the judge's ruling, that the confession was or may have been obtained by oppression or in circumstances likely to render it unreliable, they should disregard it. The voir dire ruling fixes admissibility but does not foreclose the jury's role in weighing reliability.
Holding. Certified question answered "yes": the judge must, where the issue is raised, direct the jury that if they conclude the confession was or may have been obtained by oppression or in unreliable circumstances they must disregard it. Appeal nevertheless dismissed because on the facts no miscarriage of justice resulted.
Undercover police can offer you a chance to commit a crime, but they can't push or pressure you into doing one you wouldn't otherwise have done. If they do, the whole prosecution can be stopped as an abuse of process.
Entrapment is not a substantive defence in English law, but where law-enforcement officers go beyond presenting the defendant with an "unexceptional opportunity" to commit an offence and instead incite, instigate or pressure him into committing crime he would not otherwise have committed, the proceedings constitute an abuse of the court's process. The appropriate remedy is ordinarily a stay; s.78 exclusion of the evidence of the offence is a parallel but secondary route, and in pure entrapment cases the stay is the better fit because the objection is to the prosecution itself, not to the trial fairness of any particular piece of evidence.
Holding. (i) Entrapment by state agents which goes beyond providing an unexceptional opportunity to commit crime is an abuse of process; (ii) the normal remedy is a stay of proceedings; (iii) s.78 PACE may be used to exclude evidence obtained by such conduct, but is conceptually less apt than a stay; (iv) the test for entrapment is the same whether the application is to stay or to exclude under s.78.
A police officer can't stop, search, or arrest you just because another officer told them to. They themselves must be told enough facts to make the suspicion genuinely reasonable. Bare orders from above are not enough.
Although decided under s.12(1) of the Prevention of Terrorism (Temporary Provisions) Act 1984, the reasoning is the leading authority on "reasonable grounds for suspecting" wherever it appears in PACE — including the stop-and-search threshold in section 1. The constable personally must have the suspicion and personally hold reasonable grounds for it; the test has a subjective limb (what was actually in the constable's mind) and an objective limb (whether on those facts a reasonable person would suspect). A constable cannot rely simply on a colleague's order or assertion: bare orders from a superior, unsupported by any conveyed fact, do not in themselves furnish reasonable grounds.
Holding. Reasonable suspicion has two limbs: (i) the arresting officer must subjectively suspect; (ii) there must be objectively reasonable grounds for that suspicion known to the officer at the time. A constable cannot rely on bare orders from a superior — there must be facts (however minimal) communicated to the officer that, viewed objectively, would justify the suspicion.
Before PACE, judges could rarely throw out evidence just because police behaved badly when collecting it. Section 78 changed that — giving courts a broad fairness power to exclude evidence obtained in ways that would taint the trial.
The pre-PACE common-law position was that a trial judge had no general discretion to exclude relevant evidence on the ground that it had been improperly or even unlawfully obtained, save for confessions and analogous self-incriminating evidence; nor was entrapment a substantive defence. Section 78, by giving the judge an open-textured fairness discretion over all prosecution evidence, deliberately enlarged the Sang position, reversing the Sang restriction on excluding unfairly obtained non-confession evidence.
Holding. At common law (i) entrapment is not a defence in English law; (ii) a trial judge had no general discretion to exclude evidence merely because of the manner in which it was obtained, save in the case of confessions and admissions, where unfairness in obtaining them was a recognised ground of exclusion.
If the police arrest you, they must tell you why. The only exception is when it's blindingly obvious — for example, if you're caught mid-act. Otherwise, silence on the reason makes the arrest unlawful.
The common-law principle that an arrest is unlawful unless the person arrested is told the true reason for the arrest (subject to limited exceptions where the reason is obvious from the surrounding facts) is the source from which s.28 is drawn and the lens through which s.28 is read; the duty to inform exists so the citizen knows why his liberty is taken and can challenge it.
Holding. An arrest is prima facie unlawful unless the arrested person is informed of the ground of arrest, save in the limited cases where the reason is plainly obvious (e.g. caught in flagrante delicto). This common-law duty is now embodied in s.28 PACE.
The English entrapment test from Looseley still rules — it's strong enough to satisfy human rights law. Online undercover operations against serious offences won't be thrown out simply because a Strasbourg-flavoured test is invoked.
Looseley remains binding domestic authority on entrapment and s.78. The Court of Appeal rejected the contention that the Strasbourg "police incitement" jurisprudence under Article 6 requires a stricter test; the domestic principles authoritatively stated in Looseley are sufficient to give effect to the Convention right.
Holding. Application for leave to appeal granted but appeal dismissed; the trial judge correctly applied Looseley in refusing both a category-2 stay and s.78 exclusion of online undercover material in a terrorism prosecution.
To arrest you lawfully, an officer needs both reasonable suspicion you committed an offence and a genuine, reasonable belief arrest is necessary — for example, to question you properly. They don't have to prove it was the absolute last resort.
The 2005 SOCPA rewrite of s.24 created a single arrest code for all offences and added a new requirement of necessity in s.24(4)–(5). Lawfulness now turns on two cumulative conditions: (i) the constable must have reasonable grounds for suspecting the offence and the suspect (s.24(2)–(3)); and (ii) the constable must honestly believe, on reasonable grounds, that arrest is necessary for one of the s.24(5) reasons. The pre-2006 three-stage Castorina analysis (suspicion + reasonable grounds + Wednesbury discretion) is replaced for s.24 by this two-stage statutory test, with the Wednesbury element effectively folded into the requirement of reasonable grounds for the necessity belief.
Holding. Necessity in s.24(5) does not require arrest to be a matter of "last resort"; the constable need only honestly believe, on objectively reasonable grounds, that arrest is necessary for the listed reason. The court's task is to ask: (i) did the officer believe arrest was necessary for a s.24(5) reason; (ii) were there reasonable grounds for that belief? Appeal dismissed.
A confession by someone who isn't in the dock can still be used against you, if the judge thinks it's in the interests of justice. The route is the hearsay rules — section 76A is one path, not the only path.
Section 76A creates a route by which one co-defendant may put another co-defendant's confession in evidence (subject to the s.76A(2) safeguards). It is not, however, the only route by which the Crown may seek to admit a non-defendant's confession against a defendant: the Crown can apply under s.114(1)(d) of the Criminal Justice Act 2003 to admit such a confession as hearsay in the interests of justice, with the trial judge balancing the s.114(2) factors.
Holding. Section 76A does not occupy the field. A confession by a non-defendant may be admitted by the Crown against a defendant under s.114(1)(d) CJA 2003 where it is in the interests of justice to do so. The matter was remitted for the trial judge to determine the interests-of-justice question on the merits.
Once the police have finished questioning you and gathering evidence, they can't keep you locked up just because they're waiting for the CPS to decide what to do. They must charge, bail, or release you.
The custody officer's power to detain a suspect without charge under s.37(1)–(2) is confined to detention reasonably necessary to secure or preserve evidence or to obtain it by questioning. It does not extend to keeping a suspect in police custody for the bureaucratic purpose of awaiting a charging decision from the Crown Prosecution Service once questioning has finished and the evidence is in.
Holding. Section 37(2) does not authorise continued detention of a suspect solely to obtain a charging decision from the CPS; once the investigatory rationale is exhausted, the custody officer must either charge, release on bail or release without charge under s.37(7). Appeal allowed.
To keep you in custody, the custody officer must have real, factual reasons for thinking it's necessary — to question you properly or protect evidence. Those reasons must be solidly grounded in what they were told and what they saw.
Under s.37(2), the custody officer may authorise continued detention only where he has reasonable grounds for believing it necessary to secure or preserve evidence relating to an offence for which the person is under arrest, or to obtain such evidence by questioning him. The reasonableness of the belief is a question of fact informed by what the officer was told by investigators and what he himself observed in the custody record.
Police can secretly record what you say in cells, and a court will usually let it stand. The line is drawn at deceit that pushes you into confessing — merely giving you space and silence in which you might talk is allowed.
Where the police, having lawful grounds to do so, covertly record conversations between arrested suspects (or between suspect and visitor) in police-station cells, evidence so obtained will not normally be excluded under s.78 merely because the stratagem was deceitful: there is no oppression, no questioning, and no breach of the right of silence. The court asks whether the deceit positively induced a confession or merely provided an opportunity for one; only the former engages s.78 exclusion.
Holding. Covert recording in cells, lawfully authorised, did not require exclusion under s.78. Distinction drawn between deceit that provides an opportunity to confess (admissible) and deceit that induces a confession (excluded).
Police must clear four hurdles to detain you lawfully: real grounds to suspect you, telling you why you're arrested, a real need to arrest, and proper authorisation to hold you. Fall short on any one, and your detention becomes unlawful.
Saini J followed Hayes and Parker in confirming that the lawfulness of an arrest under PACE is structured around four separate enquiries — reasonable grounds for suspicion (s.24(2)), grounds for arrest given on arrest (s.28), necessity (s.24(4)–(5)) and authorisation of detention (s.37) — each of which must be made out by the police, and any one of which, if not made out, renders the arrest or continued detention unlawful.
If you challenge an arrest, the court checks four things: did the officer suspect you, was the suspicion reasonable, did they believe arrest necessary, and was that belief reasonable. The police must prove each one.
Stuart-Smith J restated the Castorina framework as adapted for the post-2005 s.24: (1) Did the arresting officer suspect the suspect of the offence? (2) Was there reasonable cause for that suspicion? (3) Did the officer honestly believe arrest was necessary for a s.24(5) reason? (4) Were there reasonable grounds for that belief? — the "Parker Questions" now routinely used by trial courts. The burden of proving each lies on the police; the burden of any residual Wednesbury challenge lies on the arrested person.
Holding. Lawfulness of arrest under s.24 is to be tested through the four Parker Questions; pre-2006 authorities on the lawful exercise of arrest discretion must now be approached with caution.
You're entitled to legal advice, free of charge, while in custody. The custody officer must tell you so in plain, understandable terms — not gabble through a script. If they don't, anything you later say may be ruled out.
Section 58, read with the Codes, requires that the right to free legal advice be brought to the detainee's attention clearly and unambiguously, in terms appropriate to her state of mind and condition. A custody officer's mechanical recitation that does not explain the availability of the free duty solicitor scheme may amount to a breach of Code C 3.1 and 6.1, capable of grounding exclusion of any later confession.
A warrant that just says officers can grab everything connected to some unnamed offence is unlawful. You're entitled to read the warrant and understand exactly what's at stake — not be left guessing while your records walk out the door.
Applying Energy Financing, a s.8 warrant which authorises the seizure of "all" categories of business records relating to a generic "stated offence" (without identifying the offence on the face of the warrant) is unlawful: it leaves the occupier unable to discern from the warrant alone what may be seized.
Police can't just ask a magistrate for a search warrant on a thin pretext. They must lay out the real grounds — a serious offence, evidence likely on the premises — and the magistrate should record why each condition was met.
An applicant for a s.8 warrant must put before the justice all material reasonably necessary for the statutory pre-conditions to be considered: that an indictable offence has been committed, that there is material on the premises of substantial evidential value, and that one of the access conditions in s.8(3) is met. The justice should record reasons (however briefly) so that the Administrative Court can review whether each statutory requirement was addressed.
When police search your premises with a warrant, the warrant itself must clearly tell you what they can take. Vague wording referring to an unspecified investigation isn't good enough — you have the right to know on the spot.
When a justice issues a warrant under s.8 (read with the specificity requirements imported through ss.15–16), the warrant must on its face be capable of being understood both by the officers executing it and by the occupier whose premises are being searched, without recourse to the underlying information or any other document. Identifying the material sought merely as documents relating to an unspecified "investigation" does not meet that standard, because neither the executors nor the occupier necessarily know what the investigation covers.
Holding. A search warrant under s.8 must be self-contained: anyone reading it — both the searching officer and the occupier — must be able to see from the warrant alone what may be seized. Cross-reference to the underlying information or to an external "investigation" is not enough to satisfy the duty to identify the articles sought.
If your confession is challenged, the prosecution must prove beyond reasonable doubt that nothing about how it was obtained made it unreliable. The court walks through what happened, the circumstances, the likely effect, and the link to your words.
Section 76(2) requires the court (or extradition magistrate) to address four distinct questions in sequence: (a) what was said or done; (b) what were the circumstances existing at the time; (c) was what was said or done, viewed in those circumstances, likely to render unreliable any confession that might be made; (d) was the confession in fact made in consequence of that thing. Only if the prosecution proves to the criminal standard that the answer is "no" at stage (c) or (d) may the confession be admitted.
