Exam 4: Types of Evidence
Define direct evidence and circumstantial evidence. Explain the differences between them.
Direct evidence is based on first-hand observations of the person testifying. No inference or presumption is needed. If the jury believes the testimony, the facts testified about are conclusively established. For example, if the jurors believe a woman who testified that she saw the defendant shoot the victim, they must conclude that the defendant shot the victim. No other facts are needed to establish this point.Circumstantial evidence introduces one or more facts that tend to prove a fact, but jurors must draw conclusions (called inferences) based on this evidence in order to conclude that the fact exists. Unlike direct evidence, it is possible for the jurors to believe the circumstantial evidence but draw the conclusion that the event that the attorney is trying to prove did not happen. For example, a juror might believe the witness who said she saw the defendant holding a smoking gun but conclude that the defendant was not the person who fired it. The jurors are charged with weighing the evidence. Some items of circumstantial evidence are so important that they establish key elements of the offense. Other items may be of such limited value that the jurors ignore them.
Explain the difference between cumulative evidence and corroborative evidence and give an example of each.
Cumulative evidence merely repeats evidence previously introduced at the trial. Corroborative evidence supports the testimony of a previous witness by verifying details. The judge has the right to restrict cumulative evidence.For example, assume that 10 people witnessed a robbery from the same vantage point and told the police that they saw the same thing. Since the additional witnesses are providing no new evidence, the judge will deny an attorney's request to call all of them to the stand. Several will be allowed to testify but it is up to the judge's discretion exactly how many.Corroborative evidence provides additional facts to substantiate evidence that has already been admitted. It is admissible because it provides new details that will help the jury decide whether or not to believe the testimony of a prior witness. For example, a witness testified that she saw a short man with dark hair in a green shirt assault the victim at 10:00 pm.Another witness testified that he saw a short man in a green shirt leave the location at 10:02.This corroborates the testimony of the first witness by giving the same description and indicates that the man was probably at the location at the time of the crime. The testimony is not cumulative. The first witness testified that she saw the assault, the second saw the man leave the location.
Which of the following would be direct evidence in a murder case?
Relevant evidence includes any evidence that tends to prove (or disprove) a disputed fact in the case.
Sam is sitting in a courtroom doing an assignment for his evidence class. He hears Paul, the Prosecutor, and Dick, the Defense Attorney, talking to Judge John:
· Paul asked the judge to accept a stipulation that the defendant had a prior conviction. Dick denied that the defendant had ever been convicted before.
· Dick asked the judge to take judicial notice of the fact that it was daylight at 10 a.m. on June 5.
· Paul asked the judge to instruct the jury on a presumption. Dick objected on the grounds that Paul had not established the basic fact beyond a reasonable doubt. Should Judge John take judicial notice that it was daylight at 10 a.m.?
The prosecution is allowed to use presumptions to establish that the defendant is guilty:

If the attorneys stipulate to a fact, no evidence will be introduced at trial about that fact.
Relevant evidence may be excluded if its probative value is substantially outweighed by the danger of misleading the jury.
When the defendant enters a plea of "Not Guilty," all facts needed to establish the crime are placed "at issue."
If there has been a stipulation to a fact, the prosecution will not be allowed to introduce any testimony about that fact.
If the defense wants a presumption to be used, it must prove the basic fact.
