Näyttöperusteet

Näyttöperusteet refers to the legal principles and standards that govern the admissibility of evidence in a court of law. These principles are crucial for ensuring that trials are fair and that decisions are based on reliable and relevant information. The core idea behind näyttöperusteet is to prevent irrelevant, prejudicial, or unreliable evidence from influencing the outcome of a case.

In many legal systems, evidence must meet several criteria to be admitted. Firstly, it must be relevant, meaning it has a tendency to prove or disprove a fact that is important to the case. Secondly, it must be reliable. This often involves ensuring the evidence is authentic and has not been tampered with, and that its source is trustworthy. For example, witness testimony might be considered unreliable if the witness has a poor memory or a motive to lie.

Furthermore, even if evidence is relevant and reliable, it may still be excluded if its prejudicial effect outweighs its probative value. This means that if the evidence is likely to unfairly sway the jury or judge against a party, rather than helping them to understand the facts, it might be deemed inadmissible. Rules regarding hearsay, for instance, are a common example of näyttöperusteet designed to exclude potentially unreliable out-of-court statements. The specific rules and their application can vary significantly depending on the jurisdiction and the type of proceeding.
