Confessions are among the most powerful forms of evidence in criminal proceedings. A confession can be the difference between conviction and acquittal. But precisely because they are so powerful, the law imposes strict safeguards on how confessions are obtained and admitted. History is full of cases where innocent people confessed to crimes they did not commit, often because of pressure, threats, or manipulation by the authorities.
Remember that a confession is just ONE form of evidence. Even if a confession is admitted, the jury does not have to accept it as true. They can still acquit if they think the confession is unreliable. But if the confession is wrongly EXCLUDED, the prosecution's case may collapse entirely.
In this Part of this Act "confession" includes any statement wholly or partly adverse to the person who made it, whether made to a person in authority or not and whether made in words or otherwise.
The definition in s.82(1) is deliberately broad. A confession does not need to be a full admission of guilt. It can be partly adverse - for example, "I was there but I didn't do it" admits presence at the scene, which is adverse. It does not need to be made to a police officer or other person in authority - a confession to a friend is still a confession. It can be made in words or otherwise, so a nod of the head or a gesture could count.
A "mixed statement" contains both incriminating and exculpatory parts. For example, "I hit him but it was self-defence." The confession rule applies to the incriminating part (the admission of hitting), while the exculpatory part (self-defence) can be admitted as evidence of the defendant's case. The court cannot simply exclude the whole statement - it must consider each part separately.
At common law, a confession was generally admissible once it was shown to be VOLUNTARY. The CJA 2003 and PACE 1984 now govern the admissibility of confessions. The starting position is that a confession IS admissible, provided it was not obtained in a way that makes it unreliable or oppressive. The burden is on the DEFENCE to raise the issue, but once raised, the BURDEN OF PROOF shifts to the prosecution.
In any proceedings, a confession made by an accused person may be given in evidence against him in so far as it is relevant to any matter in issue in the proceedings and is not excluded by the court in pursuance of this section.
A confession must be RELEVANT to a matter in issue. A confession to a completely different offence is not admissible unless it is relevant to the current charge. For example, a confession to burglary would not be admissible in an assault trial unless the two were connected.
If the court is satisfied that the confession was obtained by oppression of the person who made it, the confession shall not be admissible.
Oppression is defined in s.76(8) of PACE 1984 as including torture, inhuman or degrading treatment, and the use or threat of violence (whether or not amounting to torture). Oppression is a HIGH threshold. It goes beyond mere pressure or discomfort. The treatment must be so serious that it overcomes the will of the person being questioned. Ordinary police pressure, even if uncomfortable, does not amount to oppression.
"Oppression" includes torture, inhuman or degrading treatment, and the use or threat of violence (whether or not amounting to torture).
Oppression is a high bar. The courts have held that ordinary questioning techniques, even aggressive ones, do not amount to oppression. There must be something fundamentally wrong with how the police treated the suspect. Merely making the suspect uncomfortable or tired is not enough.
If the court is satisfied that the confession was obtained in consequence of anything said or done which was likely to render the confession unreliable, the confession shall not be admissible.
Section 76(2)(b) focuses on the RELIABILITY of the confession rather than the treatment of the suspect. The question is: was something said or done that was likely to make the confession unreliable? This is an OBJECTIVE test - would the thing said or done be likely to render ANY confession unreliable? The focus is on the CAUSE of the confession, not just its content.
The test under s.76(2)(b) is objective: was the thing said or done LIKELY to render the confession unreliable? It does not matter whether THIS particular defendant was actually rendered unreliable - the question is whether it was LIKELY to have that effect. This is important because it means the court looks at the situation from the perspective of a reasonable person in the defendant's position.
If the suspect was intoxicated when they confessed, the court will consider whether the level of intoxication was such that the confession is likely to be unreliable. Being slightly drunk is unlikely to be enough. But if the suspect was so intoxicated that they did not understand what was happening or could not think clearly, the confession may be excluded under s.76(2)(b). The court will look at all the circumstances, including the type and amount of alcohol or drugs consumed.
A suspect with a mental disorder, learning disability, or other vulnerability may have their confession excluded if the police did not take appropriate steps to accommodate their condition. The court will consider whether the suspect understood the questions, the implications of their answers, and their right to remain silent. An "appropriate adult" should have been present under PACE Code C if the suspect was vulnerable.
If the police fail to properly caution the suspect before questioning, any confession obtained may be unreliable. The caution tells the suspect that they do not have to say anything and that anything they do say may be given in evidence. Without this warning, the suspect may not understand the significance of their answers. However, a failure to caution alone may not automatically lead to exclusion - the court must consider all the circumstances.
If in any proceedings where the prosecution proposes to give in evidence a confession made by an accused person, it is represented to the court that the confession was or may have been obtained by oppression or in consequence of anything said or done which was likely to render it unreliable, the court shall not allow the confession to be given in evidence unless it is proved to the court beyond reasonable doubt that the confession (notwithstanding that it may be true) was not obtained as aforesaid.
The BURDEN of proof under s.76(2) is on the PROSECUTION. Once the defence raises the issue (even just by saying the confession "may have been" obtained through oppression or unreliability), the prosecution must prove BEYOND REASONABLE DOUBT that the confession was NOT obtained improperly. This is the same high standard as the criminal standard of proof. If the prosecution cannot discharge this burden, the confession is excluded.
The phrase "notwithstanding that it may be true" in s.76(2) is crucial. A confession can be EXCLUDED even if it is factually accurate. The fairness of the process matters more than the truth of the confession. If the police obtained it improperly, it cannot be used, regardless of whether it is true.
The fact that a confession is wholly or partly excluded in pursuance of this section shall not affect the admissibility of any facts discovered as a result of the confession, but where a person is being tried for an offence and he has made a confession which is wholly or partly excluded, and he would not have been prosecuted or would not have been prosecuted for the offence but for the confession, the court may, if it considers it just to do so having regard to the circumstances (including the fact that the confession was so excluded), direct that the trial shall continue notwithstanding that the accused has been discharged by a jury.
This provision deals with situations where a confession by one person incriminates another. If A's confession (which mentions B) is excluded under s.76(2), can the prosecution still use that part of the confession against B? The general approach is that if A's confession is excluded, the part of it that incriminates B is also excluded. However, evidence discovered AS A RESULT of the confession (e.g. physical evidence found because of what A said) may still be admissible.
In any proceedings the court may refuse to allow evidence on which the prosecution proposes to rely to be given if it appears to the court that, having regard to all the circumstances, including the circumstances in which the evidence was obtained, the admission of the evidence would have such an adverse effect on the fairness of the proceedings that the court ought not to admit it.
Section 78 provides a SEPARATE and ADDITIONAL ground for excluding confession evidence. Even if a confession passes the s.76 test (i.e. it was not obtained through oppression or anything likely to render it unreliable), it can still be excluded under s.78 if admitting it would make the trial unfair. Section 78 is a DISCRETIONARY power, unlike s.76 which is MANDATORY (if the conditions are met, the confession MUST be excluded).
Section 78 might be used to exclude a confession where the police breached PACE Codes of Practice (e.g. by not allowing the suspect to consult a solicitor), even if the breach did not amount to oppression or unreliability under s.76. It can also apply where there were minor irregularities in the interview process, or where the circumstances of obtaining the confession, while not oppressive, were such that admitting it would undermine public confidence in the justice system.
When the defence challenges the admissibility of a confession, the jury is sent out of court and the judge holds a "trial within a trial" (also called a voir dire). This is a mini-hearing where the judge decides whether the confession should be admitted. The judge hears evidence about the circumstances in which the confession was obtained and then decides whether it should be excluded under s.76 or s.78.
If the judge excludes the confession, the jury must NOT be told anything about the voir dire or why the confession was excluded. They must not even know that a confession was made. If the judge admits the confession, the jury also does not know about the voir dire - they simply hear the confession and decide what weight to give it.
A particular difficulty arises when two or more defendants are tried together and one defendant's confession implicates another. The confessing defendant can cross-examine their own co-defendant, but the co-defendant cannot cross-examine the confessing defendant about the confession (because the confessing defendant has a right not to incriminate themselves). This creates a serious fairness problem.
Where two or more persons are charged in the same proceedings, a confession made by one of those persons (which is admissible against that person under s.76) shall not be admissible against any other of those persons unless the court is satisfied that the interests of justice require it to be admissible.
Section 76A creates a presumption that a co-defendant's confession is NOT admissible against the other defendant. The court can only admit it if the interests of justice require it. When deciding, the court will consider whether the non-confessing defendant has had a fair opportunity to challenge the confession. If the confessing defendant refuses to give evidence (exercising their right to silence), the court is more likely to exclude the confession against the co-defendant.
The PACE Codes of Practice (particularly Code C, which deals with the detention, treatment, and questioning of suspects) provide detailed guidance on how police interviews should be conducted. While a breach of the Codes is not automatically fatal to a confession, it is a relevant consideration under both s.76 and s.78. A serious breach of the Codes may render a confession unreliable under s.76(2)(b) or may justify exclusion under s.78.
When a suspect is interviewed by the police, they must be 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. Anything you do say may be given in evidence." This caution (introduced by the Criminal Justice and Public Order Act 1994) tells the suspect about their right to silence but also warns them of the potential consequences of staying silent.
Under s.34 of the Criminal Justice and Public Order Act 1994, the court or jury may draw an "adverse inference" from the suspect's failure to mention a fact when questioned that they later rely on in court. This does not compel the suspect to speak - they still have the right to remain silent. But if they stay silent and then raise a defence at trial that they could reasonably have mentioned during questioning, the jury may be told they can take that silence into account.
An adverse inference from silence can NEVER be the SOLE basis for a conviction. The jury can take the silence into account as part of their overall assessment of the evidence, but there must be other evidence that supports the conviction. The defendant's silence is just one piece of the puzzle.
The rules in s.76 and s.78 apply to ALL confessions, not just those made during police interviews. A confession made to a friend, a prison officer, a neighbour, or even posted on social media is still governed by the same admissibility rules. The difference is that confessions made outside the formal interview setting are less likely to be challenged on the basis of oppression or unreliability, because there is no police pressure involved.
A suspect who walks into a police station and says "I did it" has made a confession. This type of voluntary confession is generally admissible because it is unlikely to have been obtained through oppression or anything that would render it unreliable. However, the police should still caution the suspect before asking any further questions. If they do not, any subsequent answers could be challenged.
Article 6 of the European Convention on Human Rights guarantees the right to a fair trial. The European Court of Human Rights has held that the use of confessions obtained through ill-treatment or coercion violates Article 6. The right against self-incrimination (Article 6(1)) and the right not to be compelled to give evidence against oneself are fundamental principles. The UK courts must interpret the PACE provisions in a way that is compatible with Article 6.
When answering an exam question on confessions, work through the issues systematically: (1) Is it a confession under s.82(1)? (2) Was it obtained through oppression (s.76(2)(a))? (3) Was anything said or done likely to render it unreliable (s.76(2)(b))? (4) If not, should it be excluded under s.78? (5) Is it a co-defendant's confession (s.76A)? Apply each test to the facts and reach a conclusion.
