Elements of Evidence Flashcards
What is the Purpose of evidence law
Purpose
The purpose of this Act is to help secure the just determination of proceedings by—
(a) providing for facts to be established by the application of logical rules; and
(b) providing rules of evidence that recognise the importance of the rights affirmed by the New Zealand Bill of Rights Act 1990; and
(c) promoting fairness to parties and witnesses; and
(d) protecting rights of confidentiality and other important public interests; and
(e) avoiding unjustifiable expense and delay; and
(f) enhancing access to the law of evidence.
What is Circumstantial evidence
Circumstantial evidence is a fact from which the judge or jury may infer the existence of a fact in issue. As such, it offers indirect proof of a fact in issue. As more circumstances lead to the inference, the chain of circumstantial evidence becomes stronger, to the point where the pieces of circumstantial evidence, viewed as a whole, are sufficient to prove guilt.
The two main exceptions to the general rule are when no evidence needs to be given of facts because:
- judicial notice is taken
* the facts are formally admitted
What is a presumption?
Where no direct evidence is offerde or obtainable disputed facts are sometimes inferred from other facts which are themselves proved or known. In such cases, the inference is called a presumption.
Presumptions may be of law or of fact.
Presumptions of law
Presumptions of law are inferences that have been expressly drawn by law from particular facts.
Presumptions of law may be either conclusive or rebuttable.
Presumptions of fact
Presumptions of fact are those that the mind naturally and logically draws from the given facts. For example, one presumes that a person has guilty knowledge if they have possession of recently stolen goods.
Presumptions of fact are simply logical inferences, and so are always rebuttable
Who decides on admissibility
The judge
Evidence is admissible if it can be
legally received by a court. If evidence cannot be received, it is inadmissible.
In deciding whether evidence is admissible, the courts have reference to certain principles of evidence law. These principals are based on
- relevance
- reliability
- unfairness
Relevant evidence is defined as any
“evidence that has a tendency to prove or disprove anything that is of consequence to the determination of the proceeding”
Example of evidence that is not admissible but relevant
For example, evidence that was improperly obtained may be relevant, but may not be admissible
Even though evidence is relevant, it may be excluded if it would result in unfairness. Unfairness can cover a variety of situations and is a matter of discretion for the trial judge. It usually arises in two ways:
- Evidence may be excluded if it would result in some unfair prejudice in the proceeding.
- Evidence not prejudicial in itself in terms of the actual verdict may still be excluded where it has been obtained in circumstances that would make its admission against the defendant unfair.
Define s 8 Evidence Act - General exclusion
8 General exclusion
(1) In any proceeding, the Judge must exclude evidence if its probative value is outweighed by the risk that the evidence will—
(a) have an unfairly prejudicial effect on the proceeding; or
(b) needlessly prolong the proceeding.
Section 8 test
The s 8 test involves balancing the probative value of evidence against the risk that it will:
• have an “unfairly prejudicial effect on the proceeding” (s8(1)(a)), or
• “needlessly prolong the proceeding” (s8(1)(b)).
Evidence will be admitted under s 8 if its
probative value outweighs the risk of any unfairly prejudicial effect on the proceeding, or if it is strong enough to justify a prolonging of the proceeding.
