Question 1Political and legal systems: structures, institutions and processes

In Australia's federal system, which level of government holds the residual powers not expressly listed in the Constitution?

  1. Local government councils
  2. The state parliaments Correct answer.
  3. The High Court of Australia
  4. The Commonwealth Parliament

Explanation

The Australian Constitution lists specific heads of Commonwealth power in sections 51 and 52, and the states retain the general residual power to legislate on any matter not exclusively granted to the Commonwealth. This division reflects the federal design in which the states are general-purpose legislatures.

Question 2Political and legal systems: structures, institutions and processes

Which body formally appoints the Governor-General of Australia?

  1. The High Court
  2. The Prime Minister alone
  3. A joint sitting of Parliament
  4. The Monarch on the advice of the Prime Minister Correct answer.

Explanation

The Governor-General is appointed by the Crown on the advice of the Prime Minister, which in practice means the Prime Minister recommends the person and the Monarch makes the formal appointment. The office represents the Crown in the federal sphere rather than being elected or chosen by Parliament.

Question 3Political and legal systems: structures, institutions and processes

What is the key feature of a bicameral parliament?

  1. It separates the head of state from the head of government
  2. It has a single chamber that holds all legislative power
  3. It requires a referendum for all constitutional changes
  4. It has two houses that must both pass legislation Correct answer.

Explanation

A bicameral parliament consists of two chambers, and in the Australian Commonwealth both the House of Representatives and the Senate must agree for a bill to become law. This structure allows a second chamber to review and revise legislation.

Question 4Political and legal systems: structures, institutions and processes

In the Westminster system, which principle holds that ministers are collectively answerable to parliament for government actions?

  1. The separation of powers
  2. Responsible government Correct answer.
  3. The rule of law
  4. Judicial review

Explanation

Responsible government is the convention under which the executive is drawn from and accountable to the parliament, including collective and individual ministerial responsibility. It links the executive's authority to continuing parliamentary confidence.

Question 5Political and legal systems: structures, institutions and processes

Which court is the highest appellate court in Australia?

  1. The Supreme Court of New South Wales
  2. The Federal Circuit Court
  3. The High Court of Australia Correct answer.
  4. The Full Court of the Federal Court

Explanation

The High Court of Australia sits at the apex of the Australian judicial system and hears appeals from state and federal courts as well as exercising original constitutional jurisdiction. Its decisions bind all lower courts.

Question 6Political and legal systems: structures, institutions and processes

What is the main function of the Senate's committee system?

  1. To select the Prime Minister
  2. To conduct constitutional referendums
  3. To scrutinise legislation and government administration Correct answer.
  4. To appoint judges to the High Court

Explanation

Senate committees examine bills, conduct inquiries and question public servants, providing detailed scrutiny that the chamber as a whole cannot perform efficiently. This scrutiny role strengthens accountability of the executive to the parliament.

Question 7Political and legal systems: structures, institutions and processes

Which of the following best describes the rule of law?

  1. All persons and institutions are subject to the law Correct answer.
  2. The government may act without legal limits during emergencies
  3. Laws apply only to citizens and not to officials
  4. Only judges are bound by legal rules

Explanation

The rule of law holds that everyone, including the government and its officials, is subject to and accountable under the law. It underpins the idea that power must be exercised according to known legal rules rather than arbitrarily.

Question 8Political and legal systems: structures, institutions and processes

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

  1. The Australia Acts
  2. The Statute of Westminster
  3. The Magna Carta
  4. The Commonwealth Constitution Correct answer.

Explanation

The Commonwealth of Australia Constitution Act establishes the Parliament, its composition and its powers in Chapter I. Other statutes such as the Statute of Westminster and the Australia Acts altered imperial ties but did not create the Parliament's structure.

Question 9Political and legal systems: structures, institutions and processes

A state parliament passes a law that conflicts with a valid Commonwealth law on the same subject. Which law prevails and why?

  1. Both laws operate side by side in their respective jurisdictions
  2. The state law prevails because states retain residual power
  3. The Commonwealth law prevails because of section 109 inconsistency Correct answer.
  4. The High Court decides which law is preferable on policy grounds

Explanation

Section 109 of the Constitution 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 ensures uniformity where the Commonwealth has validly legislated.

Question 10Political and legal systems: structures, institutions and processes

A bill is introduced in the House of Representatives and passed, but the Senate rejects it twice with a three-month interval. What constitutional mechanism may follow?

  1. The High Court resolves the deadlock
  2. The bill lapses permanently
  3. The Governor-General must sign the bill into law
  4. A double dissolution of both houses may be triggered Correct answer.

Explanation

Section 57 provides that if the Senate rejects or fails to pass a bill twice with an interval of at least three months, the Governor-General may dissolve both houses. If the deadlock persists after the election, a joint sitting may be held.

Question 11Political and legal systems: structures, institutions and processes

Which feature best distinguishes the House of Representatives from the Senate in terms of composition?

  1. Members serve fixed terms that cannot be dissolved
  2. Members are appointed by state governors
  3. Members are elected to represent states equally
  4. Members are elected to represent electoral divisions based on population Correct answer.

Explanation

The House of Representatives is composed of members elected from single-member electorates allocated among the states according to population, giving it a national representative character. The Senate instead gives each state equal representation regardless of population.

Question 12Political and legal systems: structures, institutions and processes

Which of the following is an example of a constitutional convention rather than a legal rule?

  1. The prohibition on the Commonwealth imposing customs duties inconsistently
  2. The requirement that the Governor-General assent to bills
  3. The convention that the Governor-General acts on ministerial advice Correct answer.
  4. The requirement that High Court judges retire at 70

Explanation

Conventions are unwritten rules of political practice that are generally followed but not enforced by courts, such as the Governor-General acting on the advice of ministers. Legal rules, by contrast, are found in the Constitution or statutes and can be enforced judicially.

Question 13Political and legal systems: structures, institutions and processes

What is the significance of the separation of powers doctrine in the Australian Constitution?

  1. It requires all judges to be elected
  2. It gives Parliament the power to overrule court decisions
  3. It prevents the same body from exercising legislative, executive and judicial power Correct answer.
  4. It ensures the Governor-General governs personally

Explanation

The separation of powers divides governmental functions among the legislature, executive and judiciary so that no single body holds all powers, reducing the risk of arbitrary rule. In Australia the separation is most strictly applied to the judicial power, which is confined to Chapter III courts.

Question 14Political and legal systems: structures, institutions and processes

A minister resigns after a departmental failure that occurred without the minister's knowledge. Which convention is most directly engaged?

  1. The doctrine of parliamentary sovereignty
  2. Collective ministerial responsibility
  3. Individual ministerial responsibility Correct answer.
  4. The doctrine of precedent

Explanation

Individual ministerial responsibility concerns a minister's accountability to parliament for the conduct of their portfolio and department, which may include resignation in serious cases. Collective responsibility instead concerns the ministry's joint accountability for government policy.

Question 15Political and legal systems: structures, institutions and processes

What role does the High Court play in interpreting the Constitution?

  1. It advises Parliament on the political merits of bills
  2. It drafts amendments for referendum
  3. It enforces party discipline in Parliament
  4. It gives binding interpretations that shape the meaning of constitutional powers Correct answer.

Explanation

The High Court is the final arbiter of constitutional meaning, and its interpretations of provisions such as the corporations power or the external affairs power bind all governments. Its decisions can expand or constrain the practical reach of Commonwealth and state powers.

Question 16Political and legal systems: structures, institutions and processes

Which power allows the Commonwealth Parliament to legislate on matters referred to it by a state parliament?

  1. The incidental power
  2. The prerogative power of the Crown
  3. The referral power in section 51(xxxvii) Correct answer.
  4. The reserve powers of the Governor-General

Explanation

Section 51(xxxvii) permits the Commonwealth to legislate on matters referred to it by one or more state parliaments, allowing states to delegate specific legislative responsibility. This mechanism has been used to create national schemes in areas such as corporations and terrorism law.

Question 17Political and legal systems: structures, institutions and processes

A person challenges the validity of a Commonwealth law on the ground that it exceeds a head of power. Which court would ultimately determine this dispute?

  1. The Administrative Appeals Tribunal
  2. The Supreme Court of the United Kingdom
  3. The Local Court
  4. The High Court of Australia Correct answer.

Explanation

Questions about whether a Commonwealth law falls within a constitutional head of power are constitutional matters resolved ultimately by the High Court. The Court's original jurisdiction under section 75 includes matters arising under the Constitution.

Question 18Political and legal systems: structures, institutions and processes

What does the concept of parliamentary sovereignty mean in the Australian context?

  1. Parliament is bound by earlier parliaments' legislation
  2. Parliament can make or unmake any law within its constitutional limits Correct answer.
  3. Courts may override legislation on policy grounds
  4. The executive may legislate without parliamentary approval

Explanation

Parliamentary sovereignty means the legislature has the power to make, amend or repeal laws, subject in Australia to constitutional limits such as the division of powers and express or implied restrictions. Courts may invalidate legislation only where it exceeds those constitutional limits.

Question 19Political and legal systems: structures, institutions and processes

Which body has the power to disallow a regulation made under a Commonwealth Act?

  1. The High Court
  2. The Governor-General acting alone
  3. Either house of Parliament, through a disallowance motion Correct answer.
  4. The Commonwealth Ombudsman

Explanation

Delegated legislation is subject to parliamentary scrutiny, and either house may disallow a regulation within the statutory period, which removes it from operation. This provides a check on the executive's use of delegated law-making power.

Question 20Political and legal systems: structures, institutions and processes

A new Commonwealth law gives a minister an unfettered discretion to detain people without review. Which constitutional principle is most directly engaged?

  1. The reserve powers of the Crown
  2. The doctrine of responsible government
  3. The separation of judicial power Correct answer.
  4. The principle of state equality in the Senate

Explanation

Punitive detention is a judicial function, and the High Court has held that the Commonwealth Parliament cannot confer judicial power on the executive or on bodies that are not courts. A law allowing ministerial detention without judicial process raises the separation of judicial power directly.

Question 21Political and legal systems: structures, institutions and processes

How does the High Court's characterisation approach affect the scope of Commonwealth power?

  1. It looks only at the words used in the law's title
  2. It requires a referendum before any expansion of power
  3. It defers entirely to Parliament's own view of validity
  4. It examines the law's substance and practical operation to see if it falls within a head of power Correct answer.

Explanation

The Court characterises a law by reference to its real substance and practical effect rather than its form or label, which can allow the Commonwealth to rely on a head of power even where the law's purpose is indirect. This approach has contributed to the expansion of Commonwealth legislative reach over time.

Question 22Political and legal systems: structures, institutions and processes

Which statement best explains the effect of the Engineers' case on Australian federalism?

  1. It rejected implied intergovernmental immunities and favoured a literal reading of Commonwealth powers Correct answer.
  2. It expanded state reserved powers by reading them into the Constitution
  3. It transferred residual powers to local government
  4. It abolished the Senate

Explanation

The Engineers' case adopted a literal approach to interpreting Commonwealth heads of power and rejected the doctrine of implied intergovernmental immunity, which strengthened Commonwealth legislative power relative to the states. Its reasoning shaped a more centralised federation.

Question 23Political and legal systems: structures, institutions and processes

A state law imposes a licence fee on a Commonwealth agency operating in the state. Which consideration is most relevant to its validity?

  1. Whether the state law was passed before the Commonwealth law
  2. Whether the fee is set by the state treasurer
  3. Whether the law discriminates against or impairs the Commonwealth's capacity to function Correct answer.
  4. Whether the Commonwealth agency agrees to pay

Explanation

The implied intergovernmental immunity doctrine means states cannot legislate in a way that discriminates against the Commonwealth or impairs its capacity to exercise its constitutional functions. A neutral fee that does not single out the Commonwealth may be valid, so the key question is discriminatory burden or impairment.

Question 24Political and legal systems: structures, institutions and processes

Why is the High Court's power to strike down legislation considered a check on parliamentary power?

  1. Because it gives the Court control over the budget
  2. Because it allows the Court to draft replacement legislation
  3. Because it enables the Court to declare laws invalid where they exceed constitutional limits Correct answer.
  4. Because it allows the Court to dissolve Parliament

Explanation

Judicial review allows the Court to invalidate legislation that exceeds constitutional limits, so Parliament's law-making power operates within judicially enforced boundaries. This check preserves the constitutional division of powers and protects entrenched provisions.

Question 25Political and legal systems: structures, institutions and processes

In a federal system, which mechanism allows the Commonwealth and states to coordinate policy without altering the constitutional division of powers?

  1. Intergovernmental agreements through the Council of Australian Governments or national cabinet Correct answer.
  2. A referendum under section 128
  3. The exercise of reserve powers
  4. A joint sitting under section 57

Explanation

Intergovernmental forums such as the former COAG and the current national cabinet allow the Commonwealth and states to reach cooperative agreements and coordinate policy without formal constitutional change. These arrangements operate alongside, rather than replace, the constitutional allocation of powers.

Question 26Political and legal systems: structures, institutions and processes

Which chamber of the Commonwealth Parliament is elected using a system of proportional representation across states and territories?

  1. The House of Representatives
  2. The Federal Executive Council
  3. The Senate Correct answer.
  4. The Council of Australian Governments

Explanation

Senators are chosen by a proportional voting method in each state and territory, which tends to allocate seats in proportion to votes received. Members of the House of Representatives are instead elected through single-member electorates using preferential voting. The other bodies listed are not elected chambers of the legislature.

Question 27Political and legal systems: structures, institutions and processes

In a Westminster-style parliament, what is the practical effect of a minister being subject to question time?

  1. Question time transfers legislative power to the opposition
  2. Ministers are legally compelled to resign after any error
  3. Ministers must publicly account for their decisions and administration Correct answer.
  4. Question time replaces the need for judicial review of government action

Explanation

Question time is a mechanism of responsible government in which ministers answer to the parliament for their portfolios. It imposes political accountability, but it does not create legal duties to resign or alter the distribution of legislative power. Courts retain their separate role of reviewing the legality of government action.

Question 28Political and legal systems: structures, institutions and processes

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

  1. The Federal Court of Australia
  2. The High Court of Australia Correct answer.
  3. The District Court of Western Australia
  4. The Supreme Court of New South Wales

Explanation

The High Court sits at the apex of the Australian judicial system and hears appeals from federal, state and territory courts as well as matters involving the Constitution. The Federal Court and the state Supreme Courts are lower in the hierarchy, and District Courts are lower still. No Australian court sits above the High Court.

Question 29Political and legal systems: structures, institutions and processes

What is the main role of the Governor-General in relation to the Commonwealth Parliament?

  1. Granting royal assent to bills passed by both houses Correct answer.
  2. Determining the constitutionality of proposed laws
  3. Presiding over debates in the Senate
  4. Drafting government bills for introduction by ministers

Explanation

The Governor-General acts as the Crown's representative in the Commonwealth and gives royal assent before a bill becomes an Act. Bills are drafted by public servants and ministers rather than the Governor-General, and presiding officers run debates. Assessing constitutional validity is a function of the courts.

Question 30Political and legal systems: structures, institutions and processes

Which of the following best describes a referendum under section 128 of the Constitution?

  1. A vote by the states to appoint High Court justices
  2. A national vote to choose the Prime Minister
  3. A vote by parliament to amend an ordinary statute
  4. A national vote to alter the text of the Constitution Correct answer.

Explanation

Section 128 requires any proposed change to the Constitution to be approved at a referendum by a majority of voters nationally and a majority of voters in a majority of states. It does not apply to ordinary legislation, which parliament amends by passing a new Act. Choosing the Prime Minister and appointing justices are governed by other processes.

Question 31Political and legal systems: structures, institutions and processes

Which of these is a source of law made by the executive rather than by the parliament?

  1. A regulation made by the Governor-General in Council under an Act Correct answer.
  2. An Act passed by both houses of parliament
  3. A judgment of the High Court
  4. A standing order of the Senate

Explanation

Delegated or subordinate legislation, such as regulations made by the Governor-General in Council, is made by the executive under authority granted by a parent Act. Acts of parliament are made by the legislature, judgments are made by courts, and standing orders are internal rules of a house. This distinction reflects the separation between legislative and executive functions.

Question 32Political and legal systems: structures, institutions and processes

Which of the following is a function of the Commonwealth Ombudsman?

  1. Deciding whether statutes are constitutionally valid
  2. Prosecuting criminal offences in the courts
  3. Investigating complaints about administrative decisions of government agencies Correct answer.
  4. Advising the Governor-General on dissolving parliament

Explanation

The Ombudsman is an independent statutory office that investigates complaints about the administrative actions of government departments and agencies. It does not determine constitutional validity, which belongs to the courts, and it does not prosecute offences or advise on dissolution. Its role is to improve administrative accountability rather than to exercise judicial or vice-regal power.

Question 33Political and legal systems: structures, institutions and processes

What does the term 'mandate' mean when used to describe the relationship between a government and the electorate?

  1. The legal power of the Senate to reject supply bills
  2. The obligation of the High Court to follow government policy
  3. The authority a government claims to implement the policies on which it was elected Correct answer.
  4. A direction from the Governor-General to hold an early election

Explanation

A mandate is a political rather than a legal concept: a government argues that winning an election gives it authority to carry out its announced policies. It does not give the executive any power to override parliament or the courts. The Senate's powers and the High Court's independence are governed by law and are unaffected by claims of mandate.

Question 34Political and legal systems: structures, institutions and processes

A Commonwealth agency makes a decision without giving the affected person any opportunity to respond to adverse material. Which ground of judicial review is most directly engaged?

  1. A breach of the rules of procedural fairness Correct answer.
  2. A failure to obtain royal assent
  3. An improper delegation of power
  4. A lack of proportionality in the decision

Explanation

Procedural fairness, also called natural justice, requires a fair hearing and an unbiased decision-maker, so denying a person the chance to answer adverse material breaches that duty. Proportionality concerns whether a measure is excessive relative to its purpose, and delegation concerns who exercises the power. Royal assent relates to legislation, not administrative decisions.

Question 35Political and legal systems: structures, institutions and processes

Which statement best explains why the High Court is described as having both original and appellate jurisdiction?

  1. It exercises appellate jurisdiction only in criminal matters
  2. It can hear only appeals and must refer all new matters to state courts
  3. It shares its original jurisdiction with the Senate
  4. It can hear certain matters at first instance and also hear appeals from lower courts Correct answer.

Explanation

The High Court's original jurisdiction includes matters such as those arising under the Constitution, while its appellate jurisdiction allows it to review decisions of lower courts. These are distinct categories of jurisdiction conferred by the Constitution and statute. Neither is shared with the Senate, and appeals are not confined to criminal matters.

Question 36Political and legal systems: structures, institutions and processes

A local council is established by state legislation. Which statement correctly describes the constitutional position of local government in Australia?

  1. It derives its powers directly from the Governor-General
  2. It is a fourth arm of government recognised in the Constitution from 1901
  3. It is co-equal with the states in the federal division of powers
  4. It is a creation of state parliaments, which can alter or abolish it by statute Correct answer.

Explanation

Local government exists because state parliaments pass legislation creating and empowering it, so those parliaments can also change or abolish it. It was not part of the original constitutional structure and was only recognised in the Constitution through a 1988 referendum provision concerning Commonwealth funding. It is not a fourth arm of government and is subordinate to the states.

Question 37Political and legal systems: structures, institutions and processes

Which body is responsible for the formal administration of federal elections, including the drawing of electoral boundaries?

  1. The Senate Standing Committee on Regulations and Ordinances
  2. The High Court
  3. The Australian Electoral Commission Correct answer.
  4. The Department of the Prime Minister and Cabinet

Explanation

The Australian Electoral Commission is an independent statutory authority that conducts federal elections, maintains the electoral roll and oversees redistribution of boundaries through its augmented commission. Departments advise the executive but do not administer elections, and the High Court only adjudicates disputes that come before it. The Senate committee scrutinises delegated legislation rather than elections.

Question 38Political and legal systems: structures, institutions and processes

A bill passes the House of Representatives but the Senate amends it in a way the government rejects. What happens next under ordinary legislative procedure?

  1. The House may consider the amendments and, if disagreement persists, the bill may lapse or trigger a double dissolution process Correct answer.
  2. The bill automatically becomes law after thirty days
  3. The High Court resolves the disagreement between the houses
  4. The Governor-General immediately signs the original House version into law

Explanation

Both houses must agree on the text of a bill before it can receive royal assent, so disagreement leads to further consideration and possible compromise. If deadlock persists, section 57 provides a mechanism involving a double dissolution and, ultimately, a joint sitting. Neither the Governor-General nor the High Court resolves such political disagreements in the way described.

Question 39Political and legal systems: structures, institutions and processes

What is the principal purpose of the doctrine of responsible government in the Australian system?

  1. To give the judiciary the power to appoint ministers
  2. To ensure the Senate controls all government expenditure
  3. To allow the Governor-General to govern without ministers
  4. To make the executive answerable to the parliament that sustains it in office Correct answer.

Explanation

Responsible government means the executive is drawn from and remains accountable to the parliament, and the ministry must retain the confidence of the House of Representatives to stay in office. Ministers are appointed from the parliament, not by the judiciary, and the Governor-General acts on ministerial advice. The Senate reviews expenditure but does not control all of it.

Question 40Political and legal systems: structures, institutions and processes

Which statement accurately describes the composition of the Federal Executive Council?

  1. It consists of representatives of each state parliament
  2. It consists of all members of both houses of parliament
  3. It consists of ministers who advise the Governor-General and is presided over by the Governor-General Correct answer.
  4. It consists of the justices of the High Court

Explanation

The Federal Executive Council is the formal body of ministers that advises the Governor-General, who presides at its meetings. It is not a gathering of all parliamentarians, nor of judges or state representatives. Its existence reflects the constitutional structure under which the Crown acts on ministerial advice.

Question 41Political and legal systems: structures, institutions and processes

A state government wants a national scheme on a matter outside Commonwealth heads of power. Which mechanism allows the states to refer their powers so the Commonwealth can legislate uniformly?

  1. A referral of powers under section 51(xxxvii) Correct answer.
  2. A referendum under section 128
  3. A resolution of the Senate under section 57
  4. An exercise of the reserve powers by the Governor-General

Explanation

Section 51(xxxvii) permits the Commonwealth to legislate on matters referred to it by one or more state parliaments, which is how uniform national schemes are often created. Reserve powers concern the Crown's discretionary authority, section 57 deals with deadlocks between the houses, and section 128 concerns altering the Constitution. A referral is therefore the appropriate mechanism for cooperative legislative action.

Question 42Political and legal systems: structures, institutions and processes

Which of the following best explains the role of the President of the Senate?

  1. To lead the government's legislative program in the Senate
  2. To preside over Senate proceedings and maintain order and impartiality Correct answer.
  3. To decide which bills the Senate will consider
  4. To represent the Senate in the Federal Executive Council

Explanation

The President is the presiding officer of the Senate and is expected to apply the standing orders impartially and maintain order in the chamber. The Leader of the Government in the Senate manages the government's program, and the President is not the Senate's representative on the Executive Council. Deciding which bills are considered is a matter for the chamber and the government's program.

Question 43Political and legal systems: structures, institutions and processes

Which of the following best describes the function of a royal commission?

  1. To determine the validity of electoral results
  2. To pass legislation recommended by its commissioners
  3. To hear appeals from the High Court
  4. To conduct an independent public inquiry into a matter of public importance and report findings Correct answer.

Explanation

A royal commission is an independent inquiry established by the executive under letters patent or legislation to investigate matters of public importance and report its findings and recommendations. It does not legislate, hear appeals or decide electoral disputes. Its recommendations may prompt legislative change, but the commission itself has no law-making power.

Question 44Political and legal systems: structures, institutions and processes

A minister is also a member of the National Security Committee of Cabinet. Which principle explains why such a body operates in secrecy?

  1. The separation of powers requires the judiciary to approve all cabinet decisions
  2. The Constitution expressly prohibits public knowledge of cabinet business
  3. The Senate must consent to every cabinet meeting
  4. Cabinet solidarity and collective responsibility require confidential deliberation Correct answer.

Explanation

Cabinet discussions are confidential so that ministers can debate freely and then publicly support a single collective position under the convention of collective responsibility. The Constitution does not expressly prohibit disclosure, and the judiciary does not approve cabinet decisions. The Senate has no role in authorising cabinet meetings.

Question 45Political and legal systems: structures, institutions and processes

Which statement correctly describes the way the Constitution divides legislative power between the Commonwealth and the states?

  1. The Commonwealth has enumerated powers while the states retain residual powers Correct answer.
  2. All legislative power is vested in the Commonwealth alone
  3. The states have enumerated powers while the Commonwealth retains residual powers
  4. Both levels of government have identical enumerated powers

Explanation

The Constitution lists specific heads of Commonwealth power, principally in section 51, while the states retain general power to legislate for their own peace, welfare and good government, subject to any inconsistency with valid Commonwealth law. The states do not have enumerated powers in the Commonwealth sense, and the Commonwealth does not monopolise legislative authority. This allocation is the foundation of Australian federalism.

Question 46Political and legal systems: structures, institutions and processes

In Australian constitutional practice, what is meant by an 'implied freedom'?

  1. A prerogative power exercised by the Governor-General
  2. A freedom that courts find protected by the structure and text of the Constitution even though it is not expressly listed Correct answer.
  3. A statutory protection that parliament may not amend
  4. A right listed in a national bill of rights

Explanation

The High Court has held that the system of representative government established by the Constitution implies a limited freedom of political communication, even though no such right is expressly stated. Australia has no national bill of rights, and statutory protections can be amended by parliament. Prerogative powers are executive powers, not implied freedoms.

Question 47Political and legal systems: structures, institutions and processes

Which consideration best explains the High Court's approach to inconsistency between Commonwealth and state laws under section 109?

  1. Whether the state law was passed before or after the Commonwealth law
  2. Whether the Commonwealth law was supported by a referendum
  3. Whether the state parliament intended to override the Commonwealth law
  4. Whether the state law alters, impairs or detracts from the operation of the Commonwealth law Correct answer.

Explanation

The test for inconsistency focuses on whether the state law would alter, impair or detract from the operation of a valid Commonwealth law, whether by direct conflict or by covering the field. The chronological sequence of passage is not decisive, and neither referendums nor state parliamentary intention can displace a valid Commonwealth law. Section 109 renders the inconsistent state law invalid to the extent of the inconsistency.

Question 48Political and legal systems: structures, institutions and processes

What is the significance of the High Court's decision in the Tasmanian Dam case for the scope of Commonwealth power?

  1. It held that the states could legislate inconsistently with Commonwealth treaties
  2. It established that the Senate could veto treaties
  3. It removed the Commonwealth's power to legislate for the environment
  4. It confirmed that the external affairs power could support legislation implementing an international treaty obligation Correct answer.

Explanation

The case upheld Commonwealth legislation preventing a dam in Tasmania on the basis that it implemented obligations under an international convention, showing the breadth of the external affairs power. It did not give the states power to override treaties, remove Commonwealth environmental power, or give the Senate a veto over treaties. Its effect was to expand the practical reach of Commonwealth legislative power.

Question 49Political and legal systems: structures, institutions and processes

A Commonwealth law confers on a minister the power to determine whether a person is an 'unlawful non-citizen' without any statutory criteria. Which doctrine would most likely be used to challenge such a law?

  1. The doctrine of responsible government, because ministers must answer questions
  2. The doctrine of federalism, because the states may object
  3. The doctrine of parliamentary sovereignty, because parliament cannot delegate power
  4. The separation of judicial power, because the law may confer judicial functions on the executive Correct answer.

Explanation

Chapter III of the Constitution separates judicial power from the executive and legislature, so a law that authorises the executive to make determinations that are judicial in character may be invalid. Parliamentary sovereignty does not prevent delegation in general, and responsible government and federalism do not directly address the conferral of judicial functions. The challenge would therefore rest on the separation of judicial power.

Question 50Political and legal systems: structures, institutions and processes

Which statement best explains why the double dissolution mechanism in section 57 is described as a safeguard rather than a routine procedure?

  1. It is available only after a bill has been rejected twice with a three-month interval and the houses remain deadlocked Correct answer.
  2. It may be used at any time the government wishes to seek an early election
  3. It applies only to bills concerning taxation
  4. It allows the Governor-General to legislate directly when the houses disagree

Explanation

Section 57 sets specific preconditions: a bill must have been rejected twice by the Senate with an interval of at least three months and the House must again pass it before a double dissolution may be sought. These conditions make it an exceptional deadlock-resolution device rather than a routine election trigger. It does not authorise the Governor-General to legislate, and it is not confined to taxation bills.
