Section 1: Case Law & Precedent Analysis
Q1: In Johnson v. State (2022), the court held that "a warrantless entry into a home is presumptively
unreasonable under the Fourth Amendment unless exigent circumstances exist." In Miller v. State
(2025), the court faces similar facts but notes that the defendant's roommate voluntarily opened the
door and invited officers inside. Which statement is most accurate?
A. Johnson is controlling precedent, so the entry was unconstitutional regardless of the roommate's
consent.
B. Johnson is distinguishable because voluntary consent by a co-occupant removes the presumption of
unreasonableness. [CORRECT]
C. Johnson was overruled by Miller because the facts are slightly different.
D. Johnson does not apply because exigent circumstances are still required even with consent.
Correct Answer: B
Rationale: [CORRECT] Under Johnson, warrantless home entry is presumptively unreasonable, but that
presumption can be overcome by established exceptions—consent by a co-occupant with authority is a
recognized exception distinguishing this case. A is incorrect because precedent applies only when key
facts (absence of consent) match; here, the facts differ. C is incorrect; distinguishing a case is not the
same as overruling it. D is incorrect; consent is a separate exception from exigent circumstances.
Q2: A state supreme court decides Smith v. Jones, holding that "a landowner owes a duty of care to
trespassers to warn of known, artificial, highly dangerous conditions." In a later case, Brown v. Green,
the court faces a situation where a trespasser was injured by a natural condition (an old, unstable tree).
If the court follows Smith, what is the likely outcome?
,A. The landowner is liable because the condition was dangerous.
B. The landowner is not liable because Smith specifically limited the duty to "artificial" conditions.
[CORRECT]
C. The court must overrule Smith because the condition was natural.
D. The landowner is liable only if the trespasser was a child.
Correct Answer: B
Rationale: [CORRECT] Under the principle of stare decisis, the holding in Smith establishes a rule limited
to artificial conditions; therefore, the natural condition in Brown falls outside the scope of the duty
defined in Smith. A is incorrect because liability under Smith is contingent on the condition being
artificial. C is incorrect; the court can distinguish the case rather than overrule it. D is incorrect; the facts
do not suggest the attractive nuisance doctrine applies.
Q3: In State v. Adams, the majority opinion states: "The Sixth Amendment guarantees the right to
counsel in all criminal prosecutions. However, this right does not attach until the initiation of formal
judicial proceedings." Justice Diaz dissents, arguing that the right should attach upon arrest. Which part
of the majority opinion represents the ratio decidendi?
A. The statement that the Sixth Amendment guarantees the right to counsel.
B. The statement that the right does not attach until the initiation of formal judicial proceedings.
[CORRECT]
C. Justice Diaz’s dissent regarding the attachment upon arrest.
D. The discussion of the history of the Sixth Amendment in Footnote 1.
Correct Answer: B
Rationale: [CORRECT] The ratio decidendi (holding) is the legal principle applied to the facts necessary to
the decision; here, the specific rule regarding when the right attaches is the essential reasoning. A is a
general statement of law but not the specific rule resolving the case. C is incorrect because a dissent
does not create binding precedent. D is incorrect; historical discussion is typically considered obiter
dicta.
Q4: A federal district court in California is hearing a case involving a federal question. The court finds a
binding precedent from the U.S. Supreme Court and a conflicting precedent from the Ninth Circuit Court
of Appeals. Which precedent must the district court follow?
,A. The Ninth Circuit precedent because it is the immediate appellate court.
B. The U.S. Supreme Court precedent because it is the highest court in the hierarchy. [CORRECT]
C. Neither; the court may choose the reasoning it finds more persuasive.
D. The more recent of the two decisions.
Correct Answer: B
Rationale: [CORRECT] Under the doctrine of vertical stare decisis, lower courts are bound by the
decisions of higher courts within the same jurisdiction; the Supreme Court binds all lower federal courts.
A is incorrect because while the Circuit Court is the direct appellate court, it is subordinate to the
Supreme Court. C is incorrect; the court lacks discretion to ignore binding higher authority. D is
incorrect; hierarchy, not recency, determines binding authority.
Q5: In Williams v. City, the court held that "a municipality is liable for sidewalk defects only if it had
actual notice of the defect." Later, the state legislature passes a statute stating: "Municipalities shall be
liable for sidewalk defects if they had actual or constructive notice." How does this statute affect the
precedent set in Williams?
A. It affirms Williams regarding actual notice.
B. It overrules Williams regarding the notice requirement by expanding liability. [CORRECT]
C. It renders Williams persuasive authority only.
D. It invalidates the statute because it contradicts common law.
Correct Answer: B
Rationale: [CORRECT] A legislature can abrogate common law precedent by statute; here, the statute
explicitly expands the notice requirement, thereby overruling the limitation set in Williams. A is partially
true but incomplete because it ignores the expansion to constructive notice. C is incorrect; the statute is
now binding law, displacing the common law rule. D is incorrect; legislatures generally have the power
to modify common law rules.
Q6: Which of the following best describes the concept of obiter dicta?
A. Statements of law unnecessary to the decision of the case. [CORRECT]
B. The court’s order reversing the lower court.
C. The reasoning necessary to reach the holding.
, D. The dissenting opinion’s primary argument.
Correct Answer: A
Rationale: [CORRECT] Obiter dicta (or dictum) refers to comments or observations made by a judge that
are not essential to the decision and thus not binding precedent. B is the judgment or mandate, not
dicta. C describes the ratio decidendi. D is incorrect; dissenting opinions are separate from dicta of the
majority.
Q7: A court in State A is deciding a case of first impression involving liability for autonomous vehicle
accidents. The court looks to a decision from State B, which has similar traffic laws and public policy.
What is the status of the State B decision in State A?
A. Binding precedent.
B. Persuasive authority. [CORRECT]
C. Mandatory authority.
D. Obiter dicta.
Correct Answer: B
Rationale: [CORRECT] Decisions from courts of other states are not binding but may be considered
persuasive authority if the laws and policies are similar. A and C are incorrect because State B has no
jurisdictional power over State A. D is incorrect; the State B decision itself is not dicta, though specific
comments within it might be.
Q8: In Roe v. Wade, the Supreme Court held that the right to privacy protects a woman's decision to
have an abortion. In Casey v. Planned Parenthood, the Court reaffirmed the "central holding" of Roe but
replaced the trimester framework with the undue burden standard. This is an example of:
A. Overruling.
B. Distinguishing.
C. Modifying/Refining the precedent. [CORRECT]
D. Reversing.
Correct Answer: C
Rationale: [CORRECT] The Court kept the core principle (the right) but changed the test used to evaluate
restrictions, which refines the precedent without fully rejecting it. A is incorrect because the core
