What does the hearsay rule restrict in evidence law?

The hearsay rule restricts the introduction of second-hand evidence, which refers to statements made outside of the court that are offered as evidence to prove the truth of the matter asserted. This rule is based on concerns about the reliability of such evidence since the original speaker cannot be cross-examined, and thus the opportunity to challenge the credibility of that statement is diminished. Hearsay can lead to unverified information entering the court, making it difficult for the opposing party to contest its validity.

For example, if a witness tries to recount what someone else said regarding a key event, that testimony is considered hearsay and typically may not be admissible unless it falls under certain recognized exceptions to the hearsay rule. Understanding this restriction is crucial in applying evidence law correctly within court proceedings.
