NZ Constitution and Separation of Powers – Study Notes

New Zealand Constitution

  • New Zealand has a constitutional framework that establishes government structure, powers, and citizen rights.
  • Features:
    • Constitutional monarchy with a parliamentary democracy.
    • No single written document containing all constitutional matters; constitution is not entrenched.
    • With the exception of some Electoral Act provisions, there are no special procedures to change the constitution.
    • The Constitution of New Zealand is not the supreme law.
  • Sources of the Constitution (a combination of formal and informal elements):
    • Formal legal documents (statutes):

    • Imperial statutes: Magna Carta 1297, Bill of Rights 1689\text{Magna Carta } 1297, \text{ Bill of Rights } 1689
    • Letters Patent constituting the Office of the Governor-General
    • Common law (court decisions)
    • Constitutional conventions (long-standing practices)
    • Treaty of Waitangi (founding document of government in NZ)
    • International treaties and international obligations
  • Key purpose of the Constitution:
    • Sets up major institutions, their powers, and how powers are exercised
    • Regulates relationships between branches and between government and citizens
    • Provides for rights protections and obligations

The Constitution Act 1986

  • The principal formal statement of NZ’s Constitution; divided into 5 parts:
    • Part I: Acknowledges the King as Head of State; Governor-General is the King's representative in NZ.
    • Parts II–IV: Define the three branches of government and their roles:
    • Part II: The Executive (Cabinet)
    • Part III: The Legislature (Parliament)
    • Part IV: The Judiciary (judges and courts)
    • Part V: Miscellaneous provisions
  • Important characteristics:
    • The Act is not entrenched.
    • It is not the supreme law of NZ.
    • It remains a central formal statement but does not cover every constitutional matter.

The New Zealand Bill of Rights Act 1990

  • Sets out fundamental individual freedoms and rights but is not the supreme law.
  • Key provisions:

    • Section 4:No implied repeal of other legislation where that other legislation is inconsistent with the Bill of Rights\text{Section } 4: \text{No implied repeal of other legislation where that other legislation is inconsistent with the Bill of Rights}

    • Section 5:Rights and freedoms in the Bill of Rights are not absolute\text{Section } 5: \text{Rights and freedoms in the Bill of Rights are not absolute}

    • Section 6:Presumption of interpretation: legislation to be interpreted consistently with rights and freedoms in the Bill of Rights\text{Section } 6: \text{Presumption of interpretation: legislation to be interpreted consistently with rights and freedoms in the Bill of Rights}

    • Section 7:Attorney-General must report to the House of Representatives when a Bill introduced to Parliament is inconsistent with the Bill of Rights\text{Section } 7: \text{Attorney-General must report to the House of Representatives when a Bill introduced to Parliament is inconsistent with the Bill of Rights}
  • Some important rights (Part II):
    • Right to Life and Security (ss 8–11)
    • Democratic and Civil Rights (ss 12–18)
    • Non-Discriminatory and Minority Rights (ss 19–20)
    • Rights relating to Search, Arrest and Detention (ss 21–27)
  • Practical point: The Act is not the supreme law; Parliament can technically override it, though there are constitutional and political constraints.

The three branches of Government

  • Governor-General: Representative of the Crown; symbol of unity
  • Executive: Prime Minister, Cabinet, Executive Council, government departments, public service, SOEs, armed forces, police
  • Legislature: Parliament (House of Representatives), Members of Parliament (including Ministers), Speaker, select committees
  • Judiciary: Courts and judges; interprets and applies law; reviews executive action
  • Roles in practice:
    • Executive drafts laws and policy; implements policy through government departments
    • Legislature debates, scrutinises, and votes on Bills; passes Acts
    • Judiciary interprets and applies laws; resolves disputes; can review executive decisions

The Legislature (Parliament)

  • Composition and functions:
    • Governor-General acts as the King’s representative in NZ; assents to Bills; opens and dissolves Parliament; handles certain constitutional issues
    • House of Representatives: elected body; responsible for making law via a set procedure; debates proposed legislation (Bills); scrutinises government policy and actions (e.g., through questions to Ministers); provides public services via MPs
    • Speaker: elected MP; presides over House proceedings
  • Parliamentary sovereignty:
    • Parliament has absolute and unqualified power to make law (doctrine of Parliamentary sovereignty or supremacy)
    • The Constitution Act 1986 vests full lawmaking power in Parliament; a Bill becomes law when the Sovereign or Governor-General assents
    • Distinct from sovereignty of a State (ownership of territory). No higher law to which Parliament is answerable in NZ (unlike Canada/USA with a Charter or written constitution)
    • Indirect restraints on Parliament exist (general elections, parliamentary process, select committees, public opinion)
  • Legislation is the highest form of law:
    • Overrides common law and international treaties NZ has signed
    • No other country has power to legislate for NZ
  • Limitations on Parliament:
    • Some Common Law rights cannot be overridden by Parliament (e.g., prohibition against torture); Cooke J in Taylor v New Zealand Poultry Board stated: "I do not think that literal compulsion, by torture for instance, would be within the lawful powers of Parliament. Some common law rights presumably lie so deep that even Parliament could not override them." (refer McDowell & Webb, pp. 105–106)

Delegation of lawmaking (to the Executive)

  • Parliament can delegate power to other bodies (usually the Executive) to make law
  • Delegated legislation has the same legal status as parliamentary legislation if made under the authorising statute
  • If delegated legislation conflicts with other parliamentary legislation, it is subordinate to those statutes
  • Parliament cannot bind its successors:
    • Entrenchment: Parliament can make it harder to amend/repeal a law (e.g., requiring a 75% majority in the House, as in provisions concerning the parliamentary term in the former Electoral Act 1956)
    • Effectiveness of entrenchment is debatable

The Executive

  • Composition:
    • Governor-General (representative of the Crown)
    • Prime Minister (Head of Government)
    • Cabinet Ministers (Senior government MPs)
    • Executive Council (Governor-General, Prime Minister, and all Government Ministers)
    • Government departments, the Public Service, state-owned enterprises (SOEs); includes armed forces, police, and government commercial interests
  • Function:
    • Governor-General: consults, advises, and warns ministers; plays a largely formal role in executive processes
    • Prime Minister: presides over Cabinet; represents NZ overseas
    • Cabinet: formulates government policy; determines legislative program
    • Executive Council: formal communication link between Government and Governor-General
    • Government departments/ Public Service/ SOEs: implement government policy and deliver services

The Judiciary

  • Role: The referee resolving disputes between individuals and the State; balances state power and citizen rights
  • Composition: Chief Justice, President of the Court of Appeal, High Court Judges, District Court Judges
  • Functions:
    • Interpret statutes (statute law) and develop case law (common law)
    • Courts include general and specialist jurisdictions
  • Principle of interpretation:
    • Interpretation Act 1999, section 5(1): "The meaning of an enactment must be ascertained from its text and in the light of its purpose"—courts interpret legislation to give effect to Parliament’s will
  • Independence:
    • Judges of the Court of Appeal and High Court have protections against removal from office and salary reduction under the Constitution Act 1986 (Part IV)
  • The Court’s power to review executive action and ensure legality of government measures

The Doctrine of Separation of Powers

  • Purpose:
    • Each branch is confined to its own functions to prevent tyranny and abuse of power; overlapping powers create checks and balances
  • NZ does not have a pure or total separation of powers as in the United States
  • Core division of functions:
    • Legislature: makes laws
    • Executive: initiates and administers laws
    • Judiciary: applies laws

Overlaps between branches

  • Legislature and Executive:
    • Members of the Executive Council are drawn from the Legislature
    • The Governor-General is a member of both Legislature and Executive
    • Cabinet, from the governing party/coalition, strongly influences legislation and policy
    • Mixed influence from MMP (mixed-member proportional) systems on non-statutory government policy decisions
    • Legislature may delegate some lawmaking to the Executive
  • Executive and Judiciary:
    • Administrative tribunals (e.g., Waitangi Tribunal, Human Rights Review Tribunal) are part of the Executive but perform quasi-judicial functions
    • Judges are appointed by the Executive (e.g., Chief Justice appointed by the Governor-General on the Prime Minister’s advice)
    • Some executive actions can be limited by judicial review (e.g., Fitzgerald v Muldoon, 1976): a Prime Minister’s declaration to abolish a superannuation scheme was found invalid because only Parliament can override its own legislation
  • Legislature and Judiciary:
    • Parliament can enact laws that override judicial decisions (parliamentary sovereignty). Courts must apply laws as enacted
    • Notable examples:
    • Clutha Dam saga: Parliament enacted the Clutha Development Empowering Act 1982 to override a court order related to dam construction
    • Foreshore and Seabed Act 2004: Parliament expressly overruled a Court of Appeal ruling recognizing Māori customary title in foreshore and seabed areas
    • Ngāti Apa decision: Court recognised possible Māori customary title; subsequently Parliament passed the Foreshore and Seabed Act 2004 to alter the outcome
  • Courts sometimes challenge parliamentary sovereignty via statutory interpretation and case law that implicates rights under the NZBORA (e.g., R v Poumako, 2000): Court of Appeal affirmed jurisdiction to declare provisions inconsistent or incompatible with NZBORA
  • Influence of the Courts on Parliament:
    • Court decisions can influence executive policy and legislative responses (e.g., AG v. Hghati Apa)

Case illustrations and examples mentioned in the material

  • Taylor v New Zealand Poultry Board (Cooke J): rights deep in common law may limit Parliament’s power to override them
  • McDowell & Webb (pp. 105–106) cited in relation to common law rights impregnable to override by Parliament
  • Clutha Development Empowering Act 1982: Parliament used legislation to override a judicial decision regarding Clutha Dam
  • Ngāti Apa v. Attorney-General / Foreshore and Seabed Case: Court recognized potential Maori customary title; Parliament responded with Foreshore and Seabed Act 2004
  • Fitzgerald v Muldoon (1976): executive actions cannot override Parliament's legislation; judicial review limits on executive declarations
  • R v Poumako (2000) 2 NZLR 695: Court of Appeal confirmed ability to declare provisions inconsistent or incompatible with NZBORA

Practical implications and concepts discussed

  • Entrenchment:
    • Process to make amendments harder (e.g., 75% majority requirements)
    • Effectiveness is debated; not a guaranteed protection against legislative change
  • Delegated legislation:
    • Allows quicker and targeted lawmaking; must stay within the scope of the enabling statute
    • If inconsistent with Parliament’s other laws, delegated legislation is subordinate
  • Relationships between branches:
    • Overlaps are normal in practice; institutional checks and balances exist through political processes, judicial review, and legislative oversight
  • Rights protection vs. parliamentary sovereignty:
    • NZBORA provides strong rights framework but Parliament retains ultimate lawmaking power; courts can interpret and enforce rights where applicable
  • Role of treaties and international obligations:
    • NZ’s constitution interacts with but does not override domestic Acts; Parliament remains sovereign domestically, though international law and treaties influence policy and interpretation in practice
