Hearsay and the State of Mind Exception: What It Means in Criminal Trials

In criminal trials, hearsay evidence is generally not allowed. This means that statements made outside of court cannot usually be used to prove the truth of what was said. However, there are important exceptions—and one of the most significant is the “state of mind” exception.

This exception allows certain out-of-court statements to be admitted where they reflect a person’s thoughts, intentions, emotions, or beliefs at the time they were made. In the right circumstances, those statements can become powerful evidence in a criminal case.

For a statement to be admitted under this exception, it must relate to the speaker’s state of mind at the time it was made. Courts look closely at whether the statement was made naturally and without suspicion. If there are concerns that the statement was fabricated or misleading, it may be excluded.

One of the most common uses of this exception is to show intention. For example, if someone says they are going to meet a particular person, that statement may be used to support the inference that they followed through with that plan. However, it cannot be used to prove what another person intended or did.

Statements about emotions or beliefs can also be relevant. In some cases, they are used to explain behaviour or provide context for events. For example, expressions of fear, anger, or intent to leave a relationship may be used to help establish motive in serious cases.

There are important limits. Statements admitted under this exception cannot be used to prove that past events actually occurred. A statement explaining why someone felt a certain way may be partially admissible—for example, to show their intention—but not to prove the truth of the underlying events.

Even where the legal requirements are met, judges retain discretion to exclude the evidence if its potential to unfairly prejudice the accused outweighs its value. Courts are particularly cautious where there is a risk that the evidence could be misused.

In jury trials, judges must carefully instruct jurors on how they can and cannot use this type of evidence. The distinction is critical, as improper use of hearsay can undermine the fairness of the trial.
