Probative Value
Definition
The strength of the evidence's tendency to prove or disprove a fact in issue. High probative value means the evidence substantially changes the probability of the contested fact. Courts weigh probative value against prejudice when deciding whether to admit or exclude evidence under balancing rules such as FRE Rule 403.
- Definition
- The degree to which evidence makes a fact in issue more or less likely.
- Who decides

Common questions
Who decides the probative value of evidence?+
The trial judge decides probative value under the Evidence Act, not the forensic expert. Even if an expert analysis is technically sound, the court determines whether the evidence is actually relevant to the facts in dispute.
What does it mean if evidence has no probative value?+
If evidence cannot make a material fact in the case more or less probable, it has no probative value. Such evidence should be excluded from trial because it adds no weight to either side.
Does probative value apply only to physical evidence?+
No. Crime scene reconstructions are also evaluated for probative value. The standard applies: does the reconstruction make the contested facts more or less likely? If not, the court may exclude it.
