admissibility of evidence
📖 O que é admissibility of evidence? Significado e conceito
In Australian criminal law, the admissibility of evidence is a crucial step before any information can be used to decide a case. It involves the court determining if evidence, such as documents, photographs, or video recordings, meets certain legal requirements to be allowed. For example, a machine gun manual found in a home was considered admissible because the applicant's fingerprints on it made it relevant to their awareness and interest in its content, despite the manual itself not being manufactured by them.
The court often begins by considering why the evidence is relevant, meaning how it could logically affect the assessment of a fact in dispute. This is a key test under laws like the Evidence Act 1995 (NSW). For instance, photographic evidence might be admitted if it directly relates to the case, but other photographs might be rejected if they don't add value or could unfairly influence the jury.
Even if evidence is relevant, it might still be challenged. For example, video recordings of finding a bladed weapon were objected to by a co-accused. The court then weighs the 'probative value' (how much the evidence helps prove a fact) against the 'danger that the evidence might be unfairly prejudicial' (how much it might unfairly harm a party's case). If the probative value is not substantially outweighed by unfair prejudice, the evidence is generally admissible.
Judges often make decisions about admissibility 'on the run' during a trial, meaning they might rule quickly without a full appreciation of all future issues. This means that a decision on admissibility can sometimes be revisited later in the trial if new information or arguments emerge, especially depending on how the defence questions the evidence.
📋 Requisitos
- The evidence must be relevant to the proceeding, meaning it could rationally affect the assessment of a fact in issue.
- The relevance of the evidence may depend on how it is characterised and its connection to other facts, such as fingerprints on a document.
- The probative value of the evidence must not be substantially outweighed by the danger that it might be unfairly prejudicial.
- The court may consider the potential for unfair prejudice to a co-accused when deciding admissibility.
📝 Procedimento
- Counsel for a party may challenge the tender of evidence during a trial.
- The court will consider why the evidence is relevant to the proceeding, often under specific sections of an Evidence Act.
- The court assesses how the evidence, if accepted, could rationally affect the probability of a fact in issue.
- The court may weigh the probative value of the evidence against the danger of unfair prejudice.
- The judge makes a ruling on whether the evidence is admitted, which can sometimes be revisited later in the trial.
💡 Exemplos
- A machine gun manual found in a person's home was admitted as evidence because the accused's fingerprints on it suggested awareness and interest in its content, making it relevant to the case.
- Photographs taken close to the time of a birth were allowed in a criminal trial, while other photographs taken at a company were rejected because they did not add sufficient value.
- Video recordings showing the discovery of a bladed weapon were admitted despite objections, as their probative value was not substantially outweighed by the risk of unfair prejudice.
- A judge might rule 'on the run' about admitting certain photographs, noting that the decision could be revisited later depending on how the evidence develops or questions from the defence.

❓ Perguntas frequentes
What does 'relevant' mean in terms of evidence?
For evidence to be relevant, it must be able to logically affect the assessment of whether a particular fact in the case is true or not. For instance, if a document is found, its relevance might come from fingerprints on it, linking it to an accused person's knowledge or interest.
Can evidence be rejected even if it seems important?
Yes, even if evidence is relevant, it can be rejected if its 'probative value' (how much it helps prove a fact) is substantially outweighed by the danger that it might unfairly prejudice one of the parties, or confuse the jury.
What is 'unfair prejudice'?
Unfair prejudice refers to the risk that evidence might improperly influence the jury's decision, perhaps by arousing emotion or bias, rather than by its logical connection to the facts of the case. For example, overly graphic photographs might be considered unfairly prejudicial if their emotional impact outweighs their actual contribution to proving a fact.
Can a judge change their mind about admitting evidence?
Yes, a judge's decision on admissibility can sometimes be revisited later in the trial. This might happen if new information comes to light, or if the way the evidence develops during questioning by the defence changes the context.
Who decides if evidence is admissible?
The judge presiding over the trial is responsible for making rulings on the admissibility of evidence. They consider arguments from both the prosecution and the defence before making a decision.
Is there a specific law that governs admissibility?
Yes, in New South Wales, the Evidence Act 1995 (NSW) is specifically mentioned as a key piece of legislation that guides decisions on the admissibility of evidence, particularly concerning relevance and the balancing of probative value against prejudice.
