3.9 CREDIBILITY OF WITNESSES

In deciding the facts in this case, you may have to decide which testimony to believe and which testimony not to believe. You may believe everything a witness says, or part of it, or none of it.

In considering the testimony of any witness, you may take into account:

(1) the witness’s opportunity and ability to see or hear or know the things testified to;

(2) the witness’s memory;

(3) the witness’s manner while testifying;

(4) the witness’s interest in the outcome of the case, if any;

(5) the witness’s bias or prejudice, if any;

(6) whether other evidence contradicted the witness’s testimony;

(7) the reasonableness of the witness’s testimony in light of all the evidence; and

(8) any other factors that bear on believability.

The weight of the evidence as to a fact does not necessarily depend on the number of witnesses who testify. What is important is how believable the witnesses were, and how much weight you think their testimony deserves.
