Question 1Legal foundations and the Australian legal system

In Australia, which body has the constitutional authority to make laws for the Commonwealth?

The Governor-General alone
The Council of Australian Governments
The High Court of Australia
The Commonwealth Parliament Correct answer.

Explanation

Section 1 of the Commonwealth Constitution vests the legislative power of the Commonwealth in the Federal Parliament, which consists of the Queen (now the Governor-General as her representative), the Senate and the House of Representatives. The High Court interprets law but does not legislate, and the Governor-General acts on ministerial advice.

Question 2Legal foundations and the Australian legal system

Which court is the highest appellate court in the Australian court hierarchy?

The Full Court of the Federal Court
The Federal Circuit Court
The Supreme Court of each state
The High Court of Australia Correct answer.

Explanation

The High Court of Australia sits at the apex of the Australian court hierarchy, hearing appeals from state and federal courts and exercising original jurisdiction over constitutional matters. State Supreme Courts are the highest courts within their own jurisdictions but remain below the High Court.

Question 3Legal foundations and the Australian legal system

The principle that decisions of higher courts bind lower courts in the same hierarchy is known as which doctrine?

The doctrine of precedent Correct answer.
The doctrine of terra nullius
The doctrine of parliamentary sovereignty
The doctrine of responsible government

Explanation

The doctrine of precedent, or stare decisis, requires courts to follow legal principles established by superior courts in the same hierarchy where the material facts are similar. It promotes consistency and predictability in the application of law.

Question 4Legal foundations and the Australian legal system

Which document sets out the structure of the Commonwealth Parliament and the division of powers between the Commonwealth and the states?

The Magna Carta 1215
The Australia Acts 1986
The Commonwealth Constitution Correct answer.
The Statute of Westminster 1931

Explanation

The Commonwealth Constitution, enacted by the British Parliament in 1900 and commencing in 1901, establishes the federal Parliament, the executive and the judiciary, and distributes legislative power between the Commonwealth and the states. Other statutes altered particular relationships but did not create the federal structure.

Question 5Legal foundations and the Australian legal system

A law made by a local council under authority granted by state legislation is best described as which type of law?

Delegated legislation Correct answer.
Common law
International law
Constitutional law

Explanation

Delegated legislation, also called subordinate legislation, is law made by bodies such as local councils or government agencies to whom Parliament has delegated law-making power. It operates within the limits set by the enabling Act and can be disallowed by Parliament.

Question 6Legal foundations and the Australian legal system

Which feature distinguishes a criminal matter from a civil matter?

The matter involves a dispute over a contract
The matter is heard only in the High Court
The matter requires a jury to decide the outcome
The matter is brought by the state against an alleged offender Correct answer.

Explanation

Criminal proceedings are generally brought by the state (the prosecution) against an accused person, with the aim of punishing conduct that breaches the criminal law. Civil proceedings typically involve disputes between private parties seeking remedies such as compensation.

Question 7Legal foundations and the Australian legal system

Which of the following is a recognised source of law in Australia?

Media commentary on court decisions
Newspaper editorials
Statutes enacted by Parliament Correct answer.
Opinion polls

Explanation

Statutes, or Acts of Parliament, are a primary source of Australian law, alongside common law developed by the courts. Other materials may influence public debate but do not themselves create legally binding rules.

Question 8Legal foundations and the Australian legal system

What is the main purpose of the adversarial system of trial used in Australia?

To enable the government to direct the outcome of cases
To replace the need for rules of evidence
To allow the judge to investigate the facts independently
To resolve disputes through competing arguments presented by the parties Correct answer.

Explanation

In the adversarial system, two parties present their cases before an impartial decision-maker who determines the outcome based on the evidence and arguments advanced. The judge acts as an umpire rather than an investigator.

Question 9Legal foundations and the Australian legal system

A state passes a law regulating the sale of tobacco. Which head of Commonwealth power could most plausibly support a Commonwealth law on the same subject?

The trade and commerce power Correct answer.
The defence power
The external affairs power
The territories power

Explanation

Section 51(i) of the Constitution gives the Commonwealth power to make laws with respect to trade and commerce with other countries and among the states. Tobacco products moving in interstate or international trade could therefore fall within Commonwealth regulation.

Question 10Legal foundations and the Australian legal system

A case is decided in the Supreme Court of Queensland. A court lower in the Queensland hierarchy later hears a case with materially similar facts. What effect does the earlier decision have?

It is persuasive only and may be ignored
It binds the lower court as a precedent Correct answer.
It has no legal effect outside the Supreme Court
It automatically becomes an Act of Parliament

Explanation

Under the doctrine of precedent, decisions of superior courts bind courts lower in the same hierarchy when the material facts are sufficiently similar. The lower court must follow the ratio decidendi unless a higher court or Parliament changes the law.

Question 11Legal foundations and the Australian legal system

Which statement best reflects the separation of powers doctrine in the Australian Constitution?

Judicial power is vested in courts that are independent of the legislature and executive Correct answer.
The three arms of government are fully and strictly separated at all times
The executive controls the judiciary through ministerial appointments
Parliament exercises judicial power through its committees

Explanation

Chapter III of the Constitution vests judicial power in courts, and the High Court has held that federal judicial officers must be independent of the other branches. The separation is not absolute, particularly regarding the executive and legislature, but judicial independence is constitutionally protected.

Question 12Legal foundations and the Australian legal system

Which of the following best describes the concept of terra nullius as it applied to Australia before Mabo?

A statute granting land title to Indigenous communities
A constitutional provision protecting native title
A doctrine treating the land as belonging to no one at settlement Correct answer.
A legal rule recognising Aboriginal customary law as enforceable

Explanation

Terra nullius was the legal doctrine that Australia was unoccupied land at settlement, meaning no existing sovereignty or land rights were recognised. The High Court's decision in Mabo v Queensland (No 2) rejected the doctrine and recognised native title.

Question 13Legal foundations and the Australian legal system

Which of the following is an example of a residual power under the Australian federal system?

The power to make laws about immigration
The power to make laws about education Correct answer.
The power to make laws about marriage
The power to make laws about defence

Explanation

Residual powers are those left with the states after the Constitution granted specific powers to the Commonwealth. Education is not listed as a Commonwealth head of power and therefore remains primarily a state responsibility.

Question 14Legal foundations and the Australian legal system

A judge decides a case where no statute applies and no earlier decision directly covers the facts. What is the judge doing by establishing a new legal principle?

Creating delegated legislation
Amending the Constitution
Developing the common law Correct answer.
Exercising executive power

Explanation

When no statute or binding precedent resolves a matter, courts may develop the common law by reasoning from existing principles and applying them to new circumstances. This is a recognised form of judicial law-making within the court's jurisdiction.

Question 15Legal foundations and the Australian legal system

Which statement about the role of the Governor-General in the legislative process is correct?

The Governor-General votes on bills in the Senate
The Governor-General drafts all bills before Parliament
The Governor-General must assent to bills before they become law Correct answer.
The Governor-General may amend bills at will

Explanation

A bill passed by both Houses must receive royal assent from the Governor-General, acting on ministerial advice, before it becomes an Act. The Governor-General does not draft, vote on or amend legislation.

Question 16Legal foundations and the Australian legal system

Which of the following best explains why subordinate legislation must remain within the scope of its enabling Act?

Because the Constitution prohibits regulations
Because Parliament cannot delegate any law-making power
Because delegated law-making power is limited by the terms of the statute that granted it Correct answer.
Because courts draft all delegated legislation

Explanation

Delegated legislation is valid only to the extent that it is authorised by and consistent with its enabling Act. If it exceeds that authority, it may be declared invalid by a court, and Parliament may also disallow it.

Question 17Legal foundations and the Australian legal system

Which circumstance would most likely give rise to a civil rather than a criminal action?

A person is charged with assaulting a neighbour
A driver is prosecuted for exceeding the speed limit
A person is charged with theft from a shop
A company is sued for breaching a supply contract Correct answer.

Explanation

A claim that a company breached a supply contract is a civil dispute between parties seeking a remedy such as damages. Criminal matters involve the state prosecuting alleged offences and may result in penalties such as fines or imprisonment.

Question 18Legal foundations and the Australian legal system

What is the standard of proof required in a criminal trial in Australia?

To the satisfaction of the investigating police
On the balance of probabilities
On the preponderance of evidence
Beyond reasonable doubt Correct answer.

Explanation

In criminal proceedings the prosecution must prove the elements of the offence beyond reasonable doubt, reflecting the seriousness of potential penalties. The civil standard is the balance of probabilities.

Question 19Legal foundations and the Australian legal system

Which of the following best describes the effect of section 109 of the Constitution?

The High Court may repeal any state law
State laws prevail over inconsistent Commonwealth laws
State parliaments may amend the Constitution
Commonwealth laws prevail over inconsistent state laws Correct answer.

Explanation

Section 109 provides that when a state law is inconsistent with a Commonwealth law, the Commonwealth law prevails and the state law is invalid to the extent of the inconsistency. This reinforces the supremacy of Commonwealth law within its constitutional heads of power.

Question 20Legal foundations and the Australian legal system

A minister announces a new policy restricting certain imports. Which source of law would most directly authorise enforceable restrictions on imports?

A resolution of the United Nations General Assembly
A ministerial media release
Commonwealth legislation made under the trade and commerce power Correct answer.
A local council by-law

Explanation

Enforceable import restrictions require legislative authority, and the Commonwealth Parliament can legislate under section 51(i) with respect to trade and commerce with other countries. A media release announces policy but does not itself create binding legal obligations.

Question 21Legal foundations and the Australian legal system

Which statement best explains the concept of responsible government in Australia?

The executive is drawn from and accountable to the Parliament Correct answer.
The states are responsible for Commonwealth laws
The Governor-General governs without ministerial advice
The judiciary is answerable to the Parliament for its decisions

Explanation

Responsible government means the executive, comprising ministers, is drawn from and remains accountable to the Parliament, particularly the House of Representatives. Ministers must answer to Parliament, and a government that loses confidence may be required to resign or seek an election.

Question 22Legal foundations and the Australian legal system

A woman is charged with an offence. The prosecution relies on evidence obtained without a warrant. Which court would most likely hear the matter first?

The Full Court of the Federal Court
The Local Court or Magistrates Court Correct answer.
The Court of Appeal
The High Court of Australia

Explanation

Summary criminal offences are generally heard first in the Local Court or Magistrates Court, which sits at the base of the state court hierarchy. Higher courts hear more serious indictable matters or appeals.

Question 23Legal foundations and the Australian legal system

Which reasoning best explains why the High Court's interpretation of the Constitution can effectively change the balance of power between the Commonwealth and the states?

The High Court drafts constitutional amendments for referendum
The High Court determines the scope of heads of power when disputes arise Correct answer.
The High Court can suspend state constitutions
The High Court may direct Parliament to legislate in a particular area

Explanation

Because the Constitution uses broad language, the High Court's interpretation of heads of power determines how far Commonwealth legislative authority extends. Expansive interpretations, such as those concerning corporations or external affairs, have shifted practical power toward the Commonwealth without formal amendment.

Question 24Legal foundations and the Australian legal system

Which statement most accurately compares the binding force of precedent with the authority of a statute?

A valid statute prevails over a conflicting common law rule Correct answer.
A precedent always overrides a valid statute
Precedents and statutes have identical authority at all times
Statutes are only persuasive in Australian courts

Explanation

Parliament is sovereign, so a valid Act can alter or displace a common law rule, and courts must apply the statute. Precedent continues to govern where no legislation covers the issue, and courts interpret statutes rather than override them.

Question 25Legal foundations and the Australian legal system

A Commonwealth law and a state law both regulate the same activity, and compliance with one would breach the other. Which outcome follows from section 109?

The state law is invalid to the extent of the inconsistency Correct answer.
The Commonwealth law is invalid to the extent of the inconsistency
The High Court must rewrite both laws
Both laws remain fully operative

Explanation

Where a state law is inconsistent with a Commonwealth law, section 109 renders the state law invalid to the extent of the inconsistency. The Commonwealth law remains valid, provided it falls within a constitutional head of power.

Question 26Legal foundations and the Australian legal system

Which court is the highest court in the Australian court hierarchy and the final court of appeal for all Australian jurisdictions?

The Federal Court of Australia
The High Court of Australia Correct answer.
The Supreme Court of New South Wales
The Full Court of the Family Court of Australia

Explanation

The High Court of Australia sits at the apex of the federal and state court hierarchies. It hears appeals from state and federal courts and has the power to interpret the Constitution. No other Australian court can overrule its decisions.

Question 27Legal foundations and the Australian legal system

Which of the following best describes the doctrine of precedent in Australian courts?

Courts are free to decide each case on its merits without regard to earlier decisions
Only decisions of the High Court create binding rules for all courts
Courts must follow decisions of courts higher in the same hierarchy where the facts are materially similar Correct answer.
Judges must follow earlier decisions only when they personally consider them correct

Explanation

The doctrine of precedent requires a court to follow the ratio decidendi of a superior court in the same hierarchy when the material facts are similar. This promotes consistency and predictability in the law. Decisions of courts outside the hierarchy may be persuasive but are not binding.

Question 28Legal foundations and the Australian legal system

A local council makes a by-law banning dogs from a beach. A resident argues the by-law is invalid because the council's enabling Act only authorises rules about parking and rubbish. Which principle best explains the resident's argument?

Delegated legislation is invalid if it exceeds the powers conferred by its enabling Act Correct answer.
Delegated legislation is invalid whenever it conflicts with a council policy
Delegated legislation is valid only if approved by the Governor-General
Delegated legislation made by councils can never be challenged in court

Explanation

A body making delegated legislation must act within the scope of authority granted by its enabling Act. If the by-law deals with a subject outside that authority, it is ultra vires and therefore invalid. The resident's argument rests on this principle of limited delegated power.

Question 29Legal foundations and the Australian legal system

A Commonwealth law and a state law both deal with the same subject, and a person cannot comply with both. Which outcome follows from section 109 of the Constitution?

The Commonwealth law is invalid to the extent of the inconsistency
The inconsistency is resolved by a referendum of voters
Both laws remain valid and the court chooses which to apply
The state law is invalid to the extent of the inconsistency Correct answer.

Explanation

Section 109 provides that when a state law is inconsistent with a Commonwealth law, the state law is invalid to the extent of the inconsistency. The Commonwealth law prevails because it represents the national legislature's will. The invalidity operates only so far as the conflict extends.

Question 30Legal foundations and the Australian legal system

A plaintiff sues a company in negligence. The court must decide whether the company owed a duty of care where no statute and no directly applicable precedent exist. Which description best captures the court's law-making function in this situation?

The court must decline to hear the matter until Parliament enacts a relevant statute
The court develops a new principle by reasoning from analogous cases, creating a precedent that binds lower courts in later similar disputes Correct answer.
The court's decision has no effect beyond the parties and cannot influence later cases
The court applies a rule supplied by the executive government for the case

Explanation

Where statute and direct precedent are silent, judges reason by analogy from established principles to decide the case, and the resulting ratio becomes precedent for lower courts. This incremental development is a recognised form of judge-made law within the common law tradition. Parliament retains the power to override such developments by legislation.

Question 31Law-making: parliament and the courts

In Australia's federal Parliament, which body is the lower house where government is formed?

The House of Representatives Correct answer.
The Senate
The High Court
The Federal Executive Council

Explanation

The House of Representatives is the federal lower house, and the party or coalition commanding a majority there forms government. The Senate is the upper house and does not determine who forms the executive.

Question 32Law-making: parliament and the courts

Which of the following best describes a 'bill'?

A regulation made by a minister
A judgment of the High Court
A law that has already received royal assent
A proposed law introduced into Parliament Correct answer.

Explanation

A bill is a draft law presented to a house of Parliament for debate and amendment. It becomes an Act only after passing both houses and receiving royal assent.

Question 33Law-making: parliament and the courts

Which court is the highest court in the Australian court hierarchy?

The High Court of Australia Correct answer.
The District Court of Queensland
The Federal Court of Australia
The Supreme Court of New South Wales

Explanation

The High Court of Australia sits at the apex of the federal and state court hierarchies. It hears appeals from lower courts and exercises original jurisdiction on constitutional matters.

Question 34Law-making: parliament and the courts

What is the legal effect of a court applying the doctrine of precedent?

It follows a principle established by a superior court in an earlier similar case Correct answer.
It replaces the need for Parliament to legislate in that area
It creates a new statute to govern similar future disputes
It must apply any earlier decision of any court regardless of level

Explanation

Precedent requires a court to follow the ratio decidendi of a superior court in the same hierarchy when the material facts are similar. This promotes consistency and predictability in the law.

Question 35Law-making: parliament and the courts

Which of the following is a source of delegated legislation?

A regulation made by a government department under an Act Correct answer.
A ratio decidendi from a Supreme Court
A section of the Australian Constitution
A statute passed by both houses of Parliament

Explanation

Delegated legislation is law made by bodies such as departments, councils or ministers under authority granted by a parent Act. Regulations, by-laws and rules are common examples.

Question 36Law-making: parliament and the courts

Which of the following is an exclusive power of the Commonwealth Parliament?

Making laws about defence and the armed forces Correct answer.
Making laws about roads and local traffic
Making laws about hospitals
Making laws about education

Explanation

Section 51 of the Constitution grants the Commonwealth specific powers, and section 114 reserves defence exclusively to the Commonwealth. Education, roads and hospitals are not exclusive Commonwealth powers and are largely concurrent or state matters.

Question 37Law-making: parliament and the courts

Which of the following best explains why courts are described as making law when they decide cases?

They amend the Constitution through referendums
They draft and pass new statutes in Parliament
They issue regulations under delegated authority
Their interpretation of statutes and precedents can create binding rules for later cases Correct answer.

Explanation

When judges interpret ambiguous statutes or extend common law principles, the resulting ratio can bind later courts and effectively create new legal rules. This is law-making through precedent rather than through legislation.

Question 38Law-making: parliament and the courts

Which of the following is a feature of the adversarial system used in Queensland courts?

A panel of legislators decides the outcome of the dispute
Two parties present evidence and argue their case before an impartial judge or jury Correct answer.
The judge investigates the facts personally and calls all witnesses
The executive branch determines the verdict in each case

Explanation

In the adversarial system the parties, through their legal representatives, gather and present evidence and test each other's case. The judge or jury remains impartial and decides based on what is presented.

Question 39Law-making: parliament and the courts

A Queensland Supreme Court judge decides a case and states a principle of law essential to the decision. A later District Court case has materially similar facts. Which part of the earlier judgment is binding?

The dissenting judgment
The headnote summary
The obiter dicta
The ratio decidendi Correct answer.

Explanation

The ratio decidendi is the legal reasoning essential to the decision and binds lower courts in the same hierarchy on similar facts. Obiter dicta, headnotes and dissents are not binding in the same way.

Question 40Law-making: parliament and the courts

A Commonwealth minister makes a regulation that exceeds the authority given by its parent Act. Which statement best describes the legal position?

The regulation can only be challenged by a referendum
The regulation automatically becomes a statute once published
The regulation is valid because ministers can make any law they consider necessary
The regulation may be declared invalid by a court because it is beyond the power conferred Correct answer.

Explanation

Delegated legislation is valid only to the extent that it falls within the power granted by the parent Act. A court can strike down a regulation that goes beyond that authority as ultra vires.

Question 41Law-making: parliament and the courts

Which of the following best describes the role of the Senate in the federal legislative process?

It reviews and may amend or reject bills passed by the House of Representatives Correct answer.
It selects the Prime Minister after each election
It gives royal assent to bills on behalf of the Governor-General
It initiates all money bills

Explanation

The Senate acts as a house of review, scrutinising bills from the House of Representatives and able to amend or reject them. It does not choose the Prime Minister or grant royal assent.

Question 42Law-making: parliament and the courts

A state law conflicts with a valid Commonwealth law on the same subject. Which constitutional provision resolves the conflict?

Section 92 of the Constitution, which concerns free trade between the states
Section 128 of the Constitution, which sets out the referendum procedure
Section 51 of the Constitution, which lists concurrent powers
Section 109 of the Constitution, under which the state law is invalid to the extent of the inconsistency Correct answer.

Explanation

Section 109 provides that when a state law is inconsistent with a Commonwealth law, the state law is invalid to the extent of the inconsistency. This reflects the supremacy of Commonwealth law in areas of concurrent power.

Question 43Law-making: parliament and the courts

Which of the following best explains the operation of the doctrine of separation of powers in Australia?

Parliament exercises judicial power over individual criminal trials
Judges are appointed by and answerable to the executive for their decisions
Legislative, executive and judicial functions are distributed among distinct institutions, though the separation is not absolute Correct answer.
The three branches of government are completely merged in a single body

Explanation

The Constitution distributes legislative, executive and judicial power among Parliament, the executive and the courts. In practice the executive is drawn from Parliament, so the separation between legislature and executive is less strict than in the United States.

Question 44Law-making: parliament and the courts

Which of the following is a limitation on the law-making power of the Commonwealth Parliament?

It can only legislate on matters within the powers conferred by the Constitution Correct answer.
It is bound by all decisions of state District Courts
It must obtain approval from the United Nations before legislating
It cannot legislate on any subject already regulated by a state

Explanation

The Commonwealth Parliament is a parliament of enumerated powers and may legislate only where the Constitution grants authority. State parliaments, by contrast, have general legislative power subject to the Constitution.

Question 45Law-making: parliament and the courts

A bill is introduced into the House of Representatives, debated, amended and passed. What must happen next for it to become an Act?

It must pass the Senate and receive royal assent Correct answer.
It must be put to a national referendum
It must be signed by the Leader of the Opposition
It must be approved by the High Court

Explanation

A bill must pass both houses of Parliament and then receive royal assent from the Governor-General before it becomes an Act. Court approval, referendum or opposition signature are not part of the process.

Question 46Law-making: parliament and the courts

Which of the following best describes how courts can develop the common law?

By directing the executive to change its administrative practices
By repealing statutes that Parliament has enacted
By issuing regulations to implement government policy
By applying existing principles to new circumstances and extending or refining them Correct answer.

Explanation

Common law develops incrementally as judges apply established principles to novel facts and refine them in the process. Courts cannot repeal statutes, which remain the superior source of law.

Question 47Law-making: parliament and the courts

Which of the following is a reason why delegated legislation is widely used?

It overrides the parent Act whenever a conflict arises
It allows detailed rules to be made quickly by experts without going through the full parliamentary process Correct answer.
It removes the need for parliamentary scrutiny of government
It cannot be challenged in any court

Explanation

Delegated legislation enables detailed technical rules to be drafted and updated efficiently by those with expertise. It remains subordinate to the parent Act and subject to parliamentary and judicial scrutiny.

Question 48Law-making: parliament and the courts

Which of the following best explains the concept of judicial independence?

Judges are supervised by the Attorney-General when deciding cases
Judges are elected by the public at fixed intervals
Judges must follow the policy preferences of the government of the day
Judges decide cases impartially, free from direction by the executive or legislature, and enjoy security of tenure Correct answer.

Explanation

Judicial independence requires that judges decide cases according to law without interference, supported by protections such as tenure and fixed remuneration. This preserves public confidence and the rule of law.

Question 49Law-making: parliament and the courts

Which of the following statements about the doctrine of stare decisis is accurate?

It applies only to decisions of courts in other countries
It means that every judicial comment binds all later courts
It requires courts to stand by decided principles, promoting consistency and predictability Correct answer.
It allows a lower court to overrule a decision of a superior court in the same hierarchy

Explanation

Stare decisis means standing by what has been decided, so courts follow established principles in similar cases. This produces consistency, predictability and fairness in the legal system.

Question 50Law-making: parliament and the courts

A plaintiff argues that a Commonwealth Act exceeds the Commonwealth's constitutional powers. Which branch ultimately determines this question?

The legislature, through a vote in the Senate
The judiciary, through the High Court exercising its constitutional jurisdiction Correct answer.
The executive, through the Attorney-General
The Governor-General, through royal assent

Explanation

The High Court has the power to review legislation for constitutional validity and to declare an Act invalid if it exceeds Commonwealth power. This judicial review is a defining feature of the separation of powers.
