Definition - What does Hearsay Rule mean?
The hearsay rule is a rule that prohibits a witness from quoting another person (who is not present) as admissible evidence in a court case.
The reason for this rule is because the person who is being quoted is not in the court to validate whether or not the quote is accurate. Also, the person who is being quoted cannot be cross-examined since he or she is not there.
Justipedia explains Hearsay Rule
The court tries to prevent hearsay because it is second-hand information, and it is very difficult to tell whether or not it is accurate. However, there are some exceptions to the hearsay rule. For example, a dying statement given by an individual who genuinely thought that he or she was dying is admissible under the hearsay rule.
When it comes to evidence, the court tries to keep things as accurate as possible. The hearsay rule is a cautionary measure against allowing evidence that is not valid.
