Six Ways to Discredit Testimony
If an expert, the witness is not qualified.
The witness did not consider all the facts.
The witness relied on erroneous facts.
If an expert, the witness’s conclusions do not follow from a correct analysis of the facts.
The witness’s testimony is inconsistent with prior testimony.
The witness was biased or prejudiced and therefore shaded his or her perceptions or conclusions.
A fact witness employed by the defrauded party generally will be grilled more than an expert witness about bias or prejudice.
