Week’s Aims & Learning Outcomes

• Examine key features of the Australian legal system
• Analyse composition, powers & functions of core institutions: Parliament, Executive, Courts
• Understand inter-branch relationships & government–individual relations
• Outcome goal: students can explain how government works in Australia and each branch’s legislative role (making, administering, interpreting)

Key Features of the Australian Legal System

1. Constitutional Supremacy

• Australian Constitution = supreme legal & moral authority; prevails over all other laws
• Limits governmental power; enforceable by courts
• High Court in Australian Communist Party v Commonwealth (Communist Party Case) affirms rule of law as underlying constitutional assumption (Justice Dixon)

2. Rule of Law

• Contested concept; no single definition (jurisprudence field studies it)
• Core idea: supremacy of law—nobody (including state) is above it
  • Government can act only where law confers power; must remain within legal limits
• Thin / procedural conception (Joseph Raz)
  • Focuses on procedure; compatibility with unjust laws if proper process followed
• Thick / substantive conception (Lord Bingham)
  • Adds moral content; law should protect human rights & values (speech, equality, justice)
• Practical effect: constrains arbitrary power (e.g., police must have statutory authority to detain)

3. Representative Democracy

• Legislative & executive powers exercised by elected representatives or officials accountable to electorate
• People’s primary role: choose representatives through elections
• Constitutional basis: $s7$ (Senate) & $s24$ (House) — members directly chosen by the people

4. Sources of Law

• Common Law / Case Law: judge-made, via doctrine of precedent (e.g., contract law)
• Statute / Legislation: enacted by Parliament (focus of this unit)

5. Constitutional Monarchy

• King Charles III = formal Head of State; represented by Governor-General (Commonwealth) & Governors (States)
• Covering Clause $2$ ensures all constitutional references to “the Queen” extend to heirs & successors (no textual change needed after $2022$)
• Distinct from a Republic (president directly elected)

6. Federalism

• Power divided between Commonwealth and States/Territories
  • $6$ States: NSW, Vic, Qld, WA, SA, Tas
  • Centre in Canberra; also various internal/external Territories; ACT & NT possess self-government (under $s122$)
  • Local governments exist but not constitutionally recognised
• Legislative powers:
  • Concurrent: $s51$ subject-matters (shared)
  • Exclusive: $s52$ (solely Commonwealth)
  • Residual: any topic not in $s51$ or $s52$ (states)—e.g., education, criminal law, transport
• High Court ensures Commonwealth laws stay within enumerated powers
• Comparison: Unitary systems (UK, NZ) have one central legislature; federalism creates diversity of laws

7. Responsible Government (Westminster System)

• Operates via unwritten constitutional conventions (evolved from UK)
• Key conventions:
  • Executive accountable to Parliament; ministers must be MPs (evidence in $s62$ & $s64$)
  • Government must hold confidence of lower house
  • Monarch/Governor-General acts on ministerial advice
  • Ministers must report to Parliament about departmental actions
• Contrasts with US system (separate elected executive officials not sitting in legislature)

8. Separation of Powers

• Purpose: prevent concentration of power; associated with Montesquieu
• Constitutional allocation (appears strict):
  • Legislative power → Parliament ($s1$)
  • Executive power → King/GG ($s61$)
  • Judicial power → Courts ($s71$)
• Practical overlap:
  • Responsible government links Parliament + Executive (ministers in both)
  • Parliament delegates rule-making authority (delegated legislation) to Executive
  • Judges appointed by Executive

Parliament in Detail

Multi-level Structure

• Commonwealth Parliament, $6$ State Parliaments, Territory Legislative Assemblies

Parliamentary Sovereignty

• Parliament supreme source of law → can override common-law principles & reverse judicial statutory interpretations
• Australian nuance: Commonwealth Parliament bound by Constitution (enumerated powers), unlike absolute UK model
• States: plenary powers but limited by Constitution (e.g., $s109$ inconsistency rule)

Bicameral Federal Parliament

1. House of Representatives (Lower House)
   • $150$ electorates (after $2024$ redistribution; previously $151$)
   • Max term $3$ years (variable; $s28$ sets maximum, no minimum)
2. Senate (Upper House)
   • $76$ senators ( $12$ per state + $2$ per territory )
   • Senators serve $6$-year terms; half-Senate elections every $3$ years
   • Designed as State’s House & House of Review; equal state representation mitigates populous-state dominance
   • In practice, voting aligns more with party affiliation than state interests; features many minor parties/independents

Unicameral Parliaments

• Queensland: single Legislative Assembly (upper house abolished $1922$); fixed $4$-year terms (October elections)
• ACT & NT: unicameral assemblies (territorial status; powers derive from Commonwealth statutes)

Parliament’s Legislative Role

• Enacts Bills → become Acts after Royal Assent (GG or Governor)
• Delegates power to executive for subordinate legislation (regulations, rules, etc.)

Executive Branch

Composition

• King Charles III
• Governor-General (GG) – currently Her Excellency the Hon. Sam Mostyn AC (sworn $1/7/2024$)
• Federal Ministers (incl. Prime Minister & Cabinet)
• Australian Public Service (APS) – departments & agencies administering law and policy

Functions

• Administer & enforce legislation; develop policy; represent Australia internationally; manage defence, security, revenue (taxation), welfare, health, etc.
• Daily citizen contact: ATO, Services Australia, hospitals, etc.

Governor-General / Governors

• Ceremonial: open/close Parliament, preside at functions, confer honours
• Legal: grant Royal Assent, appoint officials & judges, summon/dissolve Parliament, call elections
• Constitutional (Reserve) Powers (conventions):
  • Appoint or dismiss PM
  • Independently exercisable; controversial when used (e.g., $1975$ dismissal of PM Gough Whitlam after Senate blocked supply)
  • Palace Letters (released $2020$) show Queen was not pre-informed of dismissal

Federal Executive Council

• Established $s62{-}s64$; includes all ministers
• Provides formal advice to GG; legal vehicle for executing decisions

Cabinet

• Small subset of senior ministers led by Prime Minister; drives national agenda, translates policy into legislation
• No formal constitutional mention (exists by convention)
• Relies heavily on APS for evidence & implementation

Public Service

• Neutral, merit-based officials implementing government policy across numerous departments (Treasury, DFAT, Health, etc.)
• Career avenue for law graduates (e.g., graduate programs)

State / Territory Executives

• Queensland: Executive Council = Governor + entire ministry; Cabinet & Premier explicitly recognised ($s42{-}43$ Qld Const.)
• Executive structures broadly mirror Commonwealth with contextual differences

Judiciary

Court Hierarchy Snapshot

• High Court of Australia (final appellate court; constitutional interpretation)
• Federal Courts + State/Territory Courts beneath
• Hierarchical precedent: lower courts bound by higher-court decisions

Judicial Role in Legislation

• Exclusive judicial function: conclusively determine legal meaning & effect of statutes
• Other actors (MPs, public servants) also interpret Acts, but court interpretations are authoritative & binding
• Statutory interpretation principles (text, context, purpose) maintain fidelity to Parliamentary intention and respect separation of powers
• Courts cannot make or amend statutes; if interpretation undesirable, Parliament must amend Act (e.g., immigration detention amendments after High Court release of detainees)

Case-Law Influence

• Once a court interprets a statutory term, that interpretation becomes precedent for lower courts until overturned by a higher court or overridden by legislation

Inter-Branch Dynamics & Examples

• Dialogue model: Parliament enacts → Courts interpret → Parliament may amend in response (healthy democratic cycle)
• Example Q&A discussed:
  • Immigration detention High Court decision prompted legislative amendment
  • Courts may identify unclear provisions but cannot rewrite; responsibility returns to Parliament

Philosophical & Comparative References

• Montesquieu – rationale for separated powers
• Joseph Raz (Thin Rule of Law) vs Lord Bingham (Thick Rule of Law)
• Comparison points with United States:
  • US Cabinet secretaries not in Congress; Australian ministers must be MPs
  • US judges elected; Australian judges appointed
• Influence of United Kingdom & United States on Australian constitutional design (Westminster conventions + written federal model)

Numerical / Section References (LaTeX-formatted)

• Constitutional sections: $s1,\; s7,\; s24,\; s28,\; s51,\; s52,\; s61,\; s62,\; s63,\; s64,\; s71,\; s109,\; s122$
• House electorates: $150$ (post-$2024$ redistribution; previously $151$)
• Senate composition: $12\times6 + 2\times2 = 76$ senators
• Senate terms: $6$ years; half Senate election every $3$ years
• Queensland elections: fixed $4$-year cycle (October)
• Cabinet vs ministry: Cabinet ⊂ Ministry ⊂ Executive Council

Practical Takeaways for Students

• Understand who performs each legislative phase (Parliament makes, Executive administers, Courts interpret)
• Remember constitutional limits on each branch (enumerated powers, separation principles, conventions)
• Recognise importance of statutory interpretation rules to keep courts within judicial role and honour Parliamentary supremacy
• Appreciate influence of federalism: always ask “Is this Commonwealth power or State power?” when analysing legislation
• Observe real-world operation through current events (COVID regulations, immigration cases, High Court decisions)
