Allowing evidence in the form of facts, such as testimony, to be admitted at trial by the judge depends on whether it is pertinent or relates to the issue the jury is asked to decide and whether it has probative value, meaning it helps to determine whether a fact is true or false. Once the evidence is actually admitted and the jury tries to reach a verdict they must evaluate this evidence as to its credibility. For example, if a witness saw Smith being struck by Jone’s car, the jury will determine whether the facts warrant their accepting his testimony as being a true account of what occurred, issues such as whether the witness was close enough to see what had occurred.
