Direct evidence can prove a fact all by itself and does not need backup information to
refer to. When direct evidence is used, presumptions are not required. One example of
direct evidence is the testimony of a witness who saw a crime take place. Although this
oral evidence would be secondary in nature, meaning a case could not rest on just it

piece of evidence. Opinion Evidence

of the issue and not her opinion of the facts. This is slightly different from when an
expert witness is used, because an expert is used primarily for his educated opinion.
