Relevance, in the common law of evidence, is the tendency of a given item of evidence to prove or disprove one of the legal elements of the case, or to have probative value to make one of the elements of the case likelier or not. Evidence that is irrelevant has no bearing on any of the issues, and the rules of evidence exclude it.

Relevance can be outweighed by other considerations. Evidence that is relevant may be excluded if its tendancy to prove or disprove a fact is heavily outweighed by the possibility that the evidence will prejudice or confuse the jury, or will waste the time and resource of the court.
