Issues in Evidence Flashcards
What can evidence be described as?
Information that may be presented to a court so that it may decide on the probability of some facts asserted before it, that is information by which facts in issue tend to be proved or disproved.
The two questions that need to be applied to any evidence are:
- admissibility - whether the evidence is relevant to a fact in issue. All evidence of facts in issue and all evidence which is sufficiently relevant to prove (or disprove) facts in issue are potentially admissible.
- weight - once it is established that the evidence is admissible, it is put before the court to determine what weight it will attach to the evidence, that is, how much effect does it have on proving or disproving the case (how good it is).
Can a judge exclude admissible evidence?
At common law, the trial judge has a general discretion to exclude legally admissible evidence tendered by the prosecution.
- They believe the prejudicial value outweighs the probative value.
- Evidence obtained through improper or unfair means.
- Hearsay.
- Incompetency of a Witness
- Evidence relating to previous convictions
- Privileged information or withheld as a matter of public policy.
- Non-expert opinion evidence.
In a criminal case, what are facts in issue?
In criminal cases these are facts the prosecution must prove, for example:
- the identity of the defendant;
- the actus reus;
- the mens rea.
The facts in issue fall into two distinct categories:
- the facts that the prosecution bear the burden of proving or disproving in order to establish the defendant’s guilt;
- the facts which, in exceptional circumstances, the defence need to prove to show that the defendant is not guilty.
What is the duty of the prosecution?
What is the duty of the defence?
Prosecution:
- To prove guilt.
- Beyond all reasonable doubt.
Defence:
- Level of proof is less for the defence.
- On the balance of probabilities.
- To put doubt in the minds of the Jury
What is the balance of probabilities in favour of the defence?
The defence will succeed if the court or jury are satisfied that the defence evidence is more probably true than false.
What is a good illustration of where the defence may have a burden of proof?
The law relating to the carrying of weapons.
Once the prosecution have proved (beyond a reasonable doubt) that a defendant was carrying an offensive weapon, the burden then shifts to the defence to prove (on the balance of probabilities) that the defendant had lawful authority or reasonable excuse.
There will also be occasions where the defence have what is called an evidential burden in relation to certain specific defences they intend to rely on.
What are common examples of this?
Defences relating to alibis, self- defence, accident and provocation.
In contrast to the evidential burden borne by the prosecution (to show that there is a case to answer by the end of the prosecution evidence), the defence’s evidential burden arises somewhat differently. Unlike those defences that place a full legal burden of proof on the defence, the defence do not have to satisfy the judge of anything as such. All that the defence have to do is to ensure that there is enough evidence relating to the defence that is to be raised to enable the judge to direct the jury upon that defence as a live issue.
An example of a summary offence where the burden of proof is on the defence is…
…driving without insurance where the accused is required to prove he/she is insured (Williams v Russell (1933) 149 LT 190).
An example of an indictable offence where the burden of proof is on the defence is…
…selling intoxicating liquor without a licence and the Court of Appeal held that it was for the accused to prove that he was the holder of a licence (R v Edwards [1975) QB 27).
Defence of the Defence
That the prosecution proves the prima facie case (something that has been proven or assumed to be true unless there is evidence presented to the contrary).
E.g someone found with cannabis on them…
- Burden of Proof moves to the defence that they need to show (and only on the balance of probabilities) that the defendant was taking the drugs to a Police Station.
Section 82 of the Police and Criminal Evidence Act 1984 defines what a ‘confession’ is. What is this definition?
A confession includes any statement wholly or partly adverse to the person making it, whether made to a person in authority or not and whether made in words or otherwise
The exclusion of evidence is covered in section 76 of the Police and Criminal Evidence Act 1984, where it provides the court with a responsibility to exclude confession evidence if it falls into certain categories.
What are these categories?
A court has a responsibility to exclude evidence obtained through oppression or where the confession was unreliable
DC Turner has been trying to convict local thief Ball for years. DC Turner frustrated from years of hard work that never got the conviction he wanted, decided a new tactic having watched a fictional TV programme and becoming inspired. ‘By hook or by crook’ he told himself and promptly during the interview told Ball that he found his fingerprints on the shop window that was burgled last week during a nighttime commercial burglary. There were in fact no fingerprints. Ball believing he was bang to rights, confessed to the crime.
What can be said in relation to inclusion of such evidence?
The evidence will be excluded. S78 PACE governs this around the adverse effect on the fairness of proceedings.
In relation to the exclusion of evidence, the term ‘oppression’ is often used. PACE defines for us what oppression is.
What is this?
Oppression includes torture, inhumane or degrading treatment, and the use or threat of violence
