What is the 'three-pronged test' in relation to evidence admissibility?

The 'three-pronged test' for evidence admissibility focuses on three key criteria: relevance, reliability, and the absence of unfair prejudice.

Relevance refers to whether the evidence can help prove or disprove a fact in the case. Evidence must have a direct connection to the issues at hand; it should matter to the case being tried.

Reliability pertains to the quality and trustworthiness of the evidence. For instance, the methodology behind how the evidence was collected or processed must meet established standards to ensure that it accurately reflects what it claims to represent.

The final aspect, being not unfairly prejudicial, is crucial in balancing the probative value of the evidence against the potential to unfairly sway or bias the jury. Evidence that is overly prejudicial might lead jurors to make decisions based on emotion rather than fact, which can compromise the fairness of the trial.

Thus, this three-pronged test is designed to ensure that the evidence presented in court is both relevant and trustworthy, while also protecting the integrity of the legal process by minimizing the risk of prejudice.
