What is the test for admissibility of evidence?

The test for admissibility of evidence primarily requires that the evidence must be relevant and not violate public policy. Relevance signifies that the evidence must relate directly to the facts at issue in the case, helping to substantiate a claim or defense. If the evidence is relevant, it typically gets admitted into court unless there are overriding concerns regarding public policy.

Public policy considerations can include issues such as the potential to unfairly prejudice the jury, concerns about due process, or protections against certain types of evidence that might be deemed too intrusive or harmful. For instance, evidence obtained improperly or that could invoke a negative reaction may be excluded even if it is relevant.

In contrast, the other options propose criteria that are either too broad or do not align with the established legal frameworks concerning evidence admissibility. The requirement for eyewitness testimony supports some types of evidence but is not a universal test for all admissible evidence. Similarly, the need for expert presentation may pertain to specialized types of evidence but does not form a basic requirement for admissibility across the board. Thus, the answer correctly encapsulates the foundational principles governing the admissibility of evidence in legal proceedings.
