Confessions and Exclusion of Prosecution Evidence: Introduction

This chapter answers a practical question: may the prosecution use the defendant’s own words, and what must the court do if the way those words were obtained is challenged? A confession can be powerful evidence, but an admission may result from pressure, misunderstanding or a lost safeguard. Apparent truth therefore cannot replace the legal tests for admission.

Where this fits. Deep Dive 1 explains investigation and police-station safeguards. Deep Dive 5 explains preparation and disclosure: obtaining and exchanging material is not the same as establishing that it is admissible at trial. Here, use the interview recording, custody history and disclosed material to identify the evidential issue and prepare the appropriate application. Deep Dive 7 then addresses hearsay, including proposed use of somebody else’s statement; Deep Dive 10 supplies the trial setting for rulings, directions and the verdict. These are connected stages, not a rule that every confession dispute must await completion of disclosure before it is raised.

Essential vocabulary. PACE means the Police and Criminal Evidence Act 1984. The maker is the person who made the statement. To adduce or tender evidence is to put it before the court for use as evidence. Adverse or inculpatory material counts against the maker; exculpatory material supports an innocent explanation or denies guilt. Admissibility is the legal permission to receive evidence; weight is how much reliance the fact-finder places on it afterwards. The fact-finder is the jury in an ordinary Crown Court jury trial, or the magistrates or District Judge in a summary trial. A co-accused is another defendant in the same proceedings. A legal burden of proof identifies who must establish a proposition; the standard of proof identifies how convincingly it must be established. These distinctions matter even when one court performs both the legal and fact-finding functions.

By the end, you should be able to classify a statement, identify who relies on it and against whom, select the correct statutory test and burden, identify the evidence needed for the ruling, and explain the consequence both for the statement and for the rest of the trial. Repair a classification error in section 1; a reliability or burden error in sections 2–3; a safeguards error in section 4; confusion about fairness in section 5; a party or discovered-fact error in section 6; and a direction or weight error in section 7.

Confession problems are solved by separating classification, the party using the statement and the person against whom it is used, the confession-specific section 76 rule, the separate section 78 fairness discretion, and weight after admission. Do not begin with the conclusion that police misconduct either destroys the evidence or changes nothing.
