Chapter 7: Procedures to Admit and Exclude Evidence Flashcards
Who has the burden of proof in criminal cases?
The burden of proof lies on the prosecution to prove that the defendant committed the offence charged.
What is the standard of proof in criminal cases?
The prosecution must prove their case beyond reasonable doubt.
This means they must convince the bench/judge/jury so they are reasonably sure the defendant committed the offence.
When must the defendant be acquitted?
If the defence manage to cast reasonable doubt on any element of the offence.
Why is visual identification evidence notoriously unreliable?
Because honest witnesses can nevertheless be mistaken.
When must the Turnbull guidelines be followed?
If a case wholly or substantially relies on identification evidence, and the defendant disputes the identification evidence.
What do the Turnbull guidelines do?
Set out factors to determine the strength of the identification evidence.
What are the Turnbull Guidelines?
A - amount of time the witness observed the suspect
D - distance between the witness + the suspect
V - visibility at the time of the observation
O - obstruction between witness and suspect
K - known or unknown to the witness
A - any reason to remember the suspect
T - time lapse between the incident and the identification procedure
E - errors in the witness’s first description of the defendant’s appearance
What should the judge do if they conclude the identification is weak + there is no supporting evidence?
They should withdraw the case from the jury + direct acquittal.
What will the judge do if they conclude the identification evidence is strong enough that a conviction would be supported, or if there is corroborating evidence to support a weak identification?
The judge will leave the case to the jury to decide.
What might the defence do if there is identification evidence used at trial?
If the case proceeds to trial, the defence may seek to undermine the quality of the identification evidence in cross-examination of the identification witness by going through the factors set out in ADVOKATE.
When is a Turnbull warning given?
In the summing up at the end of the trial, the judge must give the jury a Turnbull warning on the identification evidence.
What should the judge include as part of the Turnbull Warning?
- Warn of the special need for caution before convicting the defendant in reliance on identification evidence, explaining that a mistaken witness can be convincing and (when there is more than 1 witness) that several witnesses can be mistaken.
- Ask the jury to consider the circumstances in which the witness identified the defendant, and
- Refer to particular weaknesses with the identification evidence, considering the factors set out in ADVOKATE.
What impact can adverse inferences have on conviction?
Adverse inferences can weaken the defence, but a defendant cannot be convicted on the basis of an adverse inference alone.
When can an adverse inference be drawn re fact upon charge?
When the defendant fails to mention a fact when questioned or charged which the defendant reasonably could have been expected to mention.
Triggered by putting forward an explanation at trial.
Legal advice to remain silent will not necessarily preclude inference.
When can an adverse inference be drawn re giving evidence at trial?
If the defendant fails to give evidence at trial, an adverse inference can be drawn.
Unless, the defendant’s physical/mental condition makes it undesirable for them to give evidence.
When can an adverse inference be drawn re object, substance or mark?
If the defendant fails to account for an object, substance, or mark found on the defendant’s person, clothing, or footwear in their possession at the time of the arrest
When can an adverse inference be drawn from being present at the scene?
If the defendant fails to account for their presence at the scene of a suspected offence.
When does hearsay arise?
When evidence is produced in writing or when someone testifies in court to something someone else told them out of court.
What is the definition of hearsay?
A statement, not made in oral evidence, that is relied on as evidence of a matter in it.
What are examples of hearsay?
i. witness repeats in court a statement made tot hem out of court, as evidence of the truth of the content of that statement,
ii. witness statements read out in court (rather than the witness attending in person), and
iii. business documents produced in court, e.g., company account records.
When is hearsay admissible?
Only if it falls under one of the 4 categories of admissible hearsay evidence:
- admissible under statute
- admissible by rule of law
- admissible by agreement of all parties, or
- admissible in the interest of justice.
When is hearsay admissible under statute?
i. a witness is unavailable
ii. business documents (certain conditions)
iii. statements prepared for use on criminal proceedings + the relevant person cannot be expected to recollect the matter
iv. previous consistent or inconsistent statements of a witness
v. expert evidence is adduced
vi. there is a confession
When will a witness be considered unavailable?
If they are:
- dead,
- unfit owing to bodily or mental condition,
- outside of the UK and it isn’t reasonably practicable to secure their attendance, or
- unable to be found despite reasonably practicable steps having been taken to find them.
Also includes the situation in which the witness doesn’t give evidence through fear + the court gives leave for a written/recorded statement to be given in evidence.
When may a business document be adduced as admissible hearsay under statute?
If:
1. the document was created or received in the course of trade, business, profession, or other occupation,
- the person who supplied the information may reasonably be supposed to have had personal knowledge of the matter, and
- if the information was received by other persons, it was done in the course of trade, business, profession, or other occupation.
When will hearsay be admissible by rule of law?
- Confessions or mixed statements by the defendant
- Statements made contemporaneously to the offence, and
- Statements preserved by res gestae
