Before considering the specific applications of the hearsay rule, it’s important to understand why there are rules allowing certain types of evidence and banning other types. After all, the American legal system is based on the concept of “open discovery,” which means that both parties have an equal right to access all the evidence related to the case. But here’s the thing to understand—while a party may have a right to access and review all evidence related to a legal proceeding, there are limits on what evidence may be considered by the jury (or judge, if there is no jury) in reaching decisions about the case.
The primary objective of both state and federal rules of evidence is to increase the likelihood that a verdict will be based on facts rather than emotion, opinion, or insinuation. The rules of evidence also seek to ensure that all evidence considered by the jury or judge is truthful, accurate, and valid.
Though the precise language varies from state to state, and between state and federal rules of evidence, the hearsay rule essentially prevents the use of “an out-of-court statement to prove the truth of what is being said.” For example, if a witness is brought to the stand to provide evidence that the defendant stole a car, the witness would not be allowed to testify that they heard a bystander say that the defendant stole the car. The bystander’s remarks are an “out-of-court statement” because the bystander is not testifying in court; therefore, the statement is hearsay.
The hearsay rule applies to more than verbal statements. Hearsay can be contained in a note, other document, or even a nod of the head.
The fundamental issue with hearsay evidence is that the person who made the statement isn’t present, so neither the parties nor the court can take steps to establish the credibility of the statement. The bystander who made the statement about the auto theft can’t be questioned to determine if he was an eyewitness or if he made an assumption based on circumstantial evidence.
As the laws regarding hearsay have evolved, certain exceptions have emerged, based on the perception that the statements were made under circumstances that would reasonably reduce or eliminate the possibility or likelihood of inaccuracy or falsification. The following are the exceptions most commonly found in state evidence rules:
The Federal Rules of Evidence include a number of additional exceptions. Under those exceptions, the following types of hearsay can be admitted:
