Question 1: Under the Federal Rules of Evidence, evidence is relevant if it has any
tendency to make a fact more or less probable than it would be without the
evidence, and the fact is of consequence in determining the action. Which of the
following best describes the threshold for relevance?
A. The evidence must conclusively prove the fact in issue.
B. The evidence must be more probative than prejudicial.
C. The evidence need only have any tendency to make a consequential fact more or less
probable.
D. The evidence must be directly observed by a witness.
CORRECT ANSWER: C. The evidence need only have any tendency to make a
consequential fact more or less probable.
RATIONALE:Federal Rule of Evidence 401 defines relevance as evidence having any
tendency to make a fact more or less probable than it would be without the evidence,
where the fact is of consequence in determining the action. This is a very low threshold;
the evidence need not be conclusive, only probative to some degree. The balancing of
probative value against unfair prejudice occurs under Rule 403, which is a separate
inquiry from the initial relevance determination.
Question 2: A prosecutor seeks to introduce evidence that a defendant in a fraud
case purchased an expensive car shortly after the alleged scheme. The defense
objects under Rule 403. Which factor is NOT considered when a court balances
probative value against unfair prejudice?
A. Whether the evidence might inflame the jury's emotions.
B. Whether the evidence consumes undue time.
C. Whether the evidence is cumulative.
D. Whether the evidence was obtained by law enforcement.
CORRECT ANSWER: D. Whether the evidence was obtained by law enforcement.
RATIONALE:Rule 403 permits exclusion of relevant evidence if its probative value is
substantially outweighed by dangers such as unfair prejudice, confusing the issues,
misleading the jury, undue delay, wasting time, or needlessly presenting cumulative
evidence. The manner in which evidence was obtained relates to constitutional
suppression issues (e.g., Fourth Amendment violations), not the Rule 403 balancing
test, which focuses on the evidence's effect at trial.
,Question 3: In a negligence action arising from a car accident, the plaintiff offers
evidence that the defendant was texting while driving. The defendant argues the
evidence is irrelevant because the plaintiff was also negligent. How should the
court rule on relevance?
A. The evidence is irrelevant because comparative negligence bars recovery.
B. The evidence is relevant to the defendant's breach of duty, regardless of plaintiff's
conduct.
C. The evidence is irrelevant unless the plaintiff can prove the texting caused the
accident.
D. The evidence is relevant only if the defendant admits fault.
CORRECT ANSWER: B. The evidence is relevant to the defendant's breach of duty,
regardless of plaintiff's conduct.
RATIONALE:Relevance under Rule 401 is determined by whether the evidence has any
tendency to make a consequential fact more or less probable. The defendant's texting
while driving has a tendency to show breach of the duty of care, a key element of
negligence. The plaintiff's comparative negligence is a separate issue affecting damages
or liability allocation, not the relevance of evidence pertaining to the defendant's
conduct.
Question 4: Which statement accurately describes the relationship between Rule
401 relevance and Rule 403 exclusion?
A. Rule 403 exclusion applies only to evidence that is irrelevant under Rule 401.
B. Evidence must first be relevant under Rule 401 before Rule 403 balancing is applied.
C. Rule 403 can render irrelevant evidence admissible if its probative value is high.
D. Rule 401 and Rule 403 are applied simultaneously with equal weight.
CORRECT ANSWER: B. Evidence must first be relevant under Rule 401 before Rule
403 balancing is applied.
RATIONALE:The admissibility analysis is sequential. First, the court determines if
evidence is relevant under Rule 401. Only if evidence is relevant does the court proceed
to consider whether its probative value is substantially outweighed by countervailing
factors under Rule 403. Irrelevant evidence is inadmissible under Rule 402 and never
reaches Rule 403 analysis.
Question 5: A defendant in a murder trial seeks to introduce evidence that the
victim had a violent reputation to support a self-defense claim. The prosecution
objects. Under which rule is character evidence of a victim generally admissible in
a homicide case?
A. Rule 404(a)(2)(B)
B. Rule 405(b)
C. Rule 412
D. Rule 608
,CORRECT ANSWER: A. Rule 404(a)(2)(B)
RATIONALE:Rule 404(a)(2)(B) permits an accused in a homicide case to offer evidence
of a victim's pertinent trait of character (e.g., violence) to prove the victim acted in
accordance with that trait. If the accused introduces such evidence, the prosecution
may then rebut with evidence of the victim's peaceful character or the accused's same
trait. This is a specific exception to the general prohibition on character evidence to
prove conduct under Rule 404(a)(1).
Question 6: Which of the following best describes the "propensity inference" that
Rule 404(a) generally prohibits?
A. Using evidence of a person's character to prove they acted in conformity with that
character on a particular occasion.
B. Using evidence of a person's prior convictions to impeach their credibility as a
witness.
C. Using evidence of a person's habit to prove they acted in accordance with that habit
on a particular occasion.
D. Using evidence of a person's motive to prove they committed the charged act.
CORRECT ANSWER: A. Using evidence of a person's character to prove they acted
in conformity with that character on a particular occasion.
RATIONALE:Rule 404(a)(1) generally bars evidence of a person's character or character
trait to prove that on a particular occasion the person acted in accordance with the
character or trait. This is the prohibited "propensity inference" (e.g., "he is a violent
person, therefore he must have committed the assault"). Exceptions exist for accused,
victim, or witness character under specific circumstances, but the general rule forbids
propensity reasoning.
Question 7: In a civil sexual harassment lawsuit, the defendant seeks to introduce
evidence of the plaintiff's prior sexual behavior to prove consent. Which rule
primarily governs the admissibility of such evidence?
A. Rule 404(b)
B. Rule 412
C. Rule 608(b)
D. Rule 803(4)
CORRECT ANSWER: B. Rule 412
RATIONALE:Rule 412, the "rape shield" rule, generally prohibits evidence offered to
prove a victim's sexual behavior or predisposition in civil or criminal proceedings
involving sexual misconduct. In civil cases, evidence of a victim's sexual behavior or
predisposition is admissible only if its probative value substantially outweighs the
danger of harm to any victim and of unfair prejudice to any party, and it meets specific
statutory exceptions. This rule severely limits the use of prior sexual behavior to prove
consent.
, Question 8: Under Rule 404(b), evidence of other crimes, wrongs, or acts may be
admissible for non-propensity purposes. Which of the following is a permissible
non-propensity purpose?
A. To show the defendant has a criminal disposition.
B. To prove the defendant acted in conformity with a character trait.
C. To prove motive, opportunity, intent, preparation, plan, knowledge, identity, absence
of mistake, or lack of accident.
D. To demonstrate the defendant's general bad character.
CORRECT ANSWER: C. To prove motive, opportunity, intent, preparation, plan,
knowledge, identity, absence of mistake, or lack of accident.
RATIONALE:Rule 404(b)(2) explicitly lists permissible non-propensity purposes for
admitting evidence of other crimes, wrongs, or acts: proving motive, opportunity, intent,
preparation, plan, knowledge, identity, absence of mistake, or lack of accident. The
evidence must be relevant to a material issue other than character, and its probative
value must not be substantially outweighed by unfair prejudice under Rule 403.
Question 9: A prosecutor in a drug trafficking case seeks to introduce evidence that
the defendant was previously convicted of drug possession. The prosecutor argues
this shows the defendant's knowledge of the nature of the substance. What must
the court do before admitting this evidence under Rule 404(b)?
A. Automatically admit it because knowledge is a listed non-propensity purpose.
B. Determine that the prior act is relevant to a material issue other than character, and
that its probative value is not substantially outweighed by unfair prejudice.
C. Require the prosecutor to prove the prior conviction beyond a reasonable doubt.
D. Exclude it because prior convictions are never admissible under Rule 404(b).
CORRECT ANSWER: B. Determine that the prior act is relevant to a material issue
other than character, and that its probative value is not substantially outweighed by
unfair prejudice.
RATIONALE:Before admitting evidence under Rule 404(b), the court must find: (1) the
evidence is offered for a proper non-propensity purpose; (2) the evidence is relevant to
that purpose under Rule 401; (3) the evidence satisfies Rule 403's balancing test; and
(4) upon request, the court provides a limiting instruction under Rule 105. The mere
assertion of a proper purpose is insufficient; the court must perform the requisite
analysis.
Question 10: Which statement accurately describes the admissibility of habit
evidence under Rule 406?
A. Habit evidence is never admissible to prove conduct on a particular occasion.
B. Habit evidence may be admitted to prove that a person's conduct on a particular
occasion was in conformity with the habit, regardless of corroboration.
