The importance of understanding the rules governing the admissibility of evidence in criminal cases.
Police techniques to secure evidence:
Inducing others to break the law (agent provocateurs).
Evidence obtained this way is contestable but is not categorized as entrapment under English law.
Exclusion of improperly obtained evidence:
Refers to s. 78 Police & Criminal Evidence Act 1984 (PACE).
Judges can discretionally exclude evidence based on common law and statutory provisions.
Definition of entrapment: Improperly obtaining evidence without a legal defense under English law.
Assessment criteria for evidence exclusion:
Common test: comparison of probative value versus prejudicial effect.
The judge's discretion under s. 78 PACE for excluding evidence based on the fairness of proceedings.
Factors considered include circumstances of evidence acquisition and potential adverse effects on fairness.
Implications of a suspect's silence:
Criminal Justice & Public Order Act 1994 (CJPOA) allows jurors to infer guilt from a suspect's lack of explanation during police questioning.
Legal advice does not negate this condition.
Requirement: Inferences must be supported by additional evidence for establishing guilt.
Criminal Justice Act (CJA) 2003 limitations on past convictions:
Not automatically admissible as evidence in court.
Section 103 provides rules or 'gateways' for admissibility of previous convictions.
Conditions under which past convictions may be introduced:
Relevant if they indicate propensity to commit similar offenses.
Discussion point: The role of previous convictions in establishing guilt and their disclosure to a jury.
Critical role of disclosure in ensuring fair trials:
Prosecution must disclose all relevant documents for the trial.
Governed by the Criminal Procedure and Investigations Act 1996 (CPIA) amended by the Criminal Justice Act 2003.
Defense statement requirements for disclosure:
Nature of the defense.
Factual challenges to the prosecution's claims.
Supporting facts and relevant legal points.
Definition and implications of hearsay:
Statement made outside court, used in court by a witness.
Example: "Witness Y told me he saw the defendant commit the crime."
Legal foundation: Defined under section 114(1) Criminal Justice Act 2003.
Hearsay is typically inadmissible to ensure the original speaker can provide oral evidence and undergo cross-examination.
