LNAT (Legal Aptitude I) 3 — Questions and Answers
Question 1: A country's constitution states that 'all citizens are equal before the law.' Parliament then passes a law granting tax exemptions only to religious organizations. Which legal concept is most directly relevant to a challenge against this law?
- Ultra vires — Parliament has exceeded its statutory authority
- Horizontal direct effect — the constitutional right applies between private parties
- Inconsistency with constitutional equality provisions — the exemption creates unjustified differential treatment (Correct answer)
- The rule against bias — the law was passed by interested legislators
Correct answer: Inconsistency with constitutional equality provisions — the exemption creates unjustified differential treatment
A law granting exemptions to one group potentially violates constitutional equality unless the distinction can be objectively justified.
Question 2: In an LNAT reading passage, an author distinguishes between 'formal equality' and 'substantive equality.' Which statement best captures that distinction?
- Formal equality requires identical treatment; substantive equality permits differential treatment to achieve equal outcomes (Correct answer)
- Formal equality is enforced by courts; substantive equality is a policy aspiration only
- Formal equality applies to private law; substantive equality applies to public law
- Formal equality protects civil rights; substantive equality protects economic rights
Correct answer: Formal equality requires identical treatment; substantive equality permits differential treatment to achieve equal outcomes
Formal equality treats everyone identically regardless of circumstance, while substantive equality acknowledges that identical treatment can perpetuate disadvantage.
Question 3: A defendant charged with fraud argues that she lacked the necessary mens rea. What does this defence assert?
- The defendant did not commit the physical act
- The defendant had a valid alibi at the time of the offence
- The defendant did not have the guilty mind required for the crime (Correct answer)
- The defendant was acting under duress and could not be held responsible
Correct answer: The defendant did not have the guilty mind required for the crime
Mens rea refers to the mental element of a crime; arguing its absence is a claim that the defendant lacked the required guilty intention or knowledge.
Question 4: An author writes: 'The right to privacy is absolute and cannot be infringed under any circumstances.' A critic responds with the example of tax authorities inspecting financial records. This response is best described as a:
- Tu quoque — attacking the author's personal conduct rather than the argument
- Reductio ad absurdum — showing the premise leads to an absurd conclusion
- Counterexample — presenting a specific case that contradicts a universal claim (Correct answer)
- Straw man — misrepresenting the author's position before refuting it
Correct answer: Counterexample — presenting a specific case that contradicts a universal claim
One concrete case where privacy is legitimately overridden is sufficient to disprove the claim that privacy is absolute — this is the counterexample technique.
Question 5: Under the doctrine of parliamentary sovereignty in the UK, which statement is most accurate?
- Courts can strike down Acts of Parliament that conflict with human rights
- Parliament can legislate on any subject matter and no court can invalidate its Acts (Correct answer)
- The Supreme Court has the power to disapply legislation that violates the European Convention on Human Rights
- Parliamentary sovereignty is limited by the provisions of the Human Rights Act 1998
Correct answer: Parliament can legislate on any subject matter and no court can invalidate its Acts
UK parliamentary sovereignty means Parliament may make or unmake any law, and courts cannot question the validity of Acts of Parliament.
Question 6: A passage argues that international law is not 'real' law because it lacks a central enforcement mechanism. Which response most effectively challenges this argument?
- International law is real because it is written down in treaties
- Many domestic laws also lack effective enforcement yet are considered valid law
- The United Nations Security Council can enforce international obligations in some cases
- Most states comply with international law voluntarily most of the time, demonstrating that enforcement is not definitional to law (Correct answer)
Correct answer: Most states comply with international law voluntarily most of the time, demonstrating that enforcement is not definitional to law
High rates of voluntary compliance suggest that enforcement is not the defining feature of law, undermining the premise that law requires a central enforcer.
Question 7: Which of the following scenarios involves a tortious act rather than a criminal one?
- A driver intentionally runs over a pedestrian, causing death
- A factory negligently discharges chemicals that damage a neighbour's crops (Correct answer)
- A person forges a government document to obtain benefits
- A tenant threatens a landlord with violence to avoid eviction
Correct answer: A factory negligently discharges chemicals that damage a neighbour's crops
Negligence causing property damage to another is a private wrong (tort) actionable by the injured party, not a public wrong prosecuted by the state.
