Judicial Review Notes
Expansion of Judicial Review and Ultra Vires
Traditional Ultra Vires Model
Classic Concept: Under traditional Diceyan principles, public entities act legally only within the defined boundaries ("the box") set by law. Going beyond these powers is ultra vires (beyond powers).
Individual Treatment: If an official acts ultra vires, they lose legal protection and are treated as a private citizen committing an unlawful act (Entick v Carrington; Fitzgerald v Muldoon).
Breakdown of Ouster Clauses: Anisminic Ltd v Foreign Compensation Commission
Historical Context (1956 Suez Crisis):
Egyptian President Gamal Abdel Nasser nationalized the Suez Canal (owned by an Anglo-French private corporation). Egypt blockaded the Straits of Tiran, preventing Israeli access to Eilat.
Britain, France, and Israel executed a secret agreement (Protocol of Sèvres): Israel invaded the Sinai Peninsula, and British/French forces intervened under the pretext of peacekeepers.
The military action failed politically, civilian casualties ensued, Egyptians sank ships blocking the canal for two years, and Anglo-French forces withdrew under United States economic pressure.
The Compensation Fund: Egypt paid a lump-sum compensation fund to the UK government for confiscated property. The UK established the Foreign Compensation Commission (FCC) to process property claims.
Facts of the Claim:
Anisminic Ltd (formerly Sinai Mining Company) owned mining assets in the Sinai Peninsula valued in the millions.
Following Egyptian seizure, Anisminic sold its assets under duress to TIDO (an Egyptian government economic development organization) for £500,000 (significantly below market value).
Anisminic applied to the FCC for recovery from the compensation fund.
Ouster Clause (Section 4): Stated that the determination by the Commission of any application "shall not be called into question in any court of law."
Judicial Reasoning and Significance:
To bypass the explicit statutory ouster clause, the House of Lords held that if a body makes an error of law in interpreting its statutory criteria (e.g., misinterpreting the requirements regarding a successor in title or British nationality), that error takes the body outside its jurisdiction.
A decision made outside jurisdiction is a legal nullity—it never legally existed.
Consequently, the court held it was not "calling a determination into question," but rather declaring that no valid determination was ever made.
Impact: Expanded the ultra vires doctrine. Any error of law can potentially take a decision-maker outside their jurisdiction, making executive decision-making far more porous to judicial scrutiny.
Affirmation in New Zealand: Bulk Gas Corporation Ltd v Attorney-General
Facts: The Natural Gas Corporation applied to the Secretary of Energy to increase gas prices. Bulk Gas, a major users group, was not granted a hearing prior to the decision being made.
Ouster Clause (Section 86): Stated that except on grounds of lack of jurisdiction, no order, approval, proceeding, or decision of the Secretary shall be liable to be challenged, reviewed, quashed, or called into question in any court.
Legal Holding: The Court of Appeal confirmed that the Anisminic principle applies in New Zealand: an error in interpreting statutory criteria takes the decision outside jurisdiction.
Outcome: Although the court checked the decision and ultimately found that the Secretary had not made an error of law (and thus allowed the decision to stand), the case definitively established that ouster clauses cannot bar New Zealand courts from reviewing errors of law.
Scope and Reach of Judicial Review
Statutory Power vs. Common Law Review
Judicial Review Procedures Act 2016:
Applies whenever a body exercises a "statutory power" or "statutory power of decision" under an Act, constitution, or regulations (e.g., powers to make regulations, issue licenses, or affect legal rights).
Provides streamlined statutory mechanics and remedies (replaces the Judicature Amendment Act 1972).
Common Law / Prerogative Review:
Applies to exercises of public power that do not originate directly from a specific statute (e.g., prerogative powers, de facto public authority, soft law mechanisms).
Uses traditional common law prerogative remedies (certiorari, prohibition, mandamus, declaration).
Review of De Facto Public Power (Non-Statutory Bodies)
R v Panel on Takeovers and Mergers, ex parte Datafin plc (UK):
Issue: Whether a private, self-regulatory body with no statutory or prerogative basis was subject to judicial review.
Holding: The Panel exercised immense de facto public control over securities markets and corporate takeovers, and its decisions triggered statutory interventions. The court held that bodies exercising public duties or de facto public power are subject to judicial review regardless of their source of authority.
Royal Australasian College of Surgeons v Phipps (NZ):
Issue: Whether a report prepared by a professional surgical college reviewing a surgeon's practice for a public health board was reviewable.
Holding: The Court of Appeal confirmed that non-statutory bodies exercising powers with public consequences, professional reputational impacts, and public health ramifications are subject to public law judicial review principles.
Conceptual Framework for Judicial Review Grounds
Judicial review grounds can be structured logically into four core inquiries:
Who (Jurisdiction & Authority): Did the decision-maker possess the lawful authority to make the decision? (Covers ultra vires, statutory interpretation, delegation, and improper composition).
How (Procedural Fairness): Was the decision made using proper procedural steps? (Covers rules of natural justice, freedom from bias, right to a fair hearing, and statutory procedural compliance).
Why (Inputs & Process): Were the correct legal inputs and reasoning applied? (Covers taking into account relevant considerations, ignoring irrelevant considerations, improper purpose, and bad faith).
Output (Substantive Rationality): Does the decision cross substantive legal thresholds? (Covers unreasonableness/irrationality, proportionality, and breaches of fundamental human rights under NZBORA).
Legal Authority and State Power (The "Who" Inquiry)
Types of Executive Power
Imperium Power:
The sovereign power of the state to compel compliance, impose duties, and restrict individual liberties (e.g., taxation, criminal prosecution, land acquisition).
Requires explicit, positive legal authority (statute or recognized royal prerogative).
Dominion Power:
Power exercised by the state as a property owner, employer, or commercial entity (e.g., entering contracts, managing public assets).
The "Third Source" of Power Controversy
The Broad View (Malone v Metropolitan Police Commissioner):
Context: Police tapped Malone's phone without explicit statutory authority, as telephone tapping was unregulated in UK law at the time.
Holding: McGarry VC held that the Crown/State can do anything a private individual can do unless specifically prohibited by law ("if it is not unlawful, it is lawful").
Judicial Critique and Rejection:
UK Position (R v Secretary of State for Health, ex parte Fewings): Laws J and Lord Bingham rejected the private individual analogy for public authorities, holding that public bodies possess no private rights for their own sake and every public action must be justified by positive legal authority.
New Zealand Position (Hamid v R):
Context: Police conducted unauthorized video surveillance on private property during the 2007 Urewera raids.
Holding: The Supreme Court (Elias CJ) explicitly rejected Malone in New Zealand, ruling that executive interference with individual liberty or privacy requires positive legal authorization under statute. Evidence obtained without statutory authorization was declared unlawful.
Ombudsman
Foundations and Constitutional Role of the New Zealand Ombudsman
Historical Origins and Lineage:
The Office of the Ombudsman was established in New Zealand in the 1960s.
The inaugural Ombudsman was Guy Poles, who held the position for decades and established the institutional, operational, and philosophical foundations of the office.
Successive Ombudsmen have maintained and elevated the office's constitutional standing, including Brian Elwood, Dame Bev Wakum, and Sir Peter Boscher (a former Chief Family Court Judge).
John Allen assumed the role of Chief Ombudsman around March 2025, having previously practiced as a lawyer in private practice, served extensively across the public sector, and held the office of Chancellor of Te Haringa Waka (Victoria University of Wellington).
Constitutional Independence and Legal Authority:
The Ombudsman is an Officer of Parliament, not an agent of the executive government, Crown, or Wellington bureaucracy.
The office operates independently to scrutinize state administration and speaks truth directly to government agencies, senior public service leaders, and politicians.
The central mandate is the protection of the individual and the systemic improvement of administrative processes across the state sector.
The moral authority of the office is grounded in the mana of the Parliament of New Zealand, ensuring that state agencies and state-adjacent entities adhere to its recommendations.
Foundational Philosophy and Guiding Principles:
Guy Poles defined the Ombudsman as Parliament's officer established for the protection of the individual, guided by four core touchstones: honor, sympathy, justice, and reason, reporting whenever these qualities are absent.
The operational ethos displayed within the office is "fairness for all," aligning with John Rawls' philosophical framework of radical inclusion and egalitarianism.
Distinctive Characteristics: Ombudsman Jurisdiction vs. Judicial Review
Fundamental Structural Distinctions from Courts:
The Office of the Ombudsman is not a court, not court-adjacent, and does not operate as an adversarial tribunal.
The office does not require its head to be a judge, nor do its officers wear robes or wigs.
Procedural and Operational Contrasts:
Private Investigations vs. Public Proceedings: Court proceedings are public and open to external observation, whereas Ombudsman investigations are conducted entirely in private.
Inquisitorial Latitude vs. Pleadings: Courts are strictly confined to formal pleadings submitted by legal counsel. The Ombudsman operates inquisitorially, pursuing independent lines of inquiry across administrative or systemic contexts without pleading restrictions.
Financial Accessibility: Applications for judicial review in the courts entail prohibitive legal costs; the Ombudsman process is entirely free of charge to the complainant (taxpayer-funded).
Remedial Breadth: Court remedies in administrative law are generally bounded by doctrines of formal legality. The Ombudsman evaluates whether decisions or administrative acts are reasonable or unreasonable, unjust, or simply wrong, and can determine that an underlying statute or government policy is flawed.
Absence of Strict Precedent: The Ombudsman is not bound by a strict doctrine of judicial precedent (stare decisis); each officeholder is legally entitled to form their own independent view in response to changing societal standards.
Own-Motion Inquiries: Courts cannot adjudicate without an active claim filed by a plaintiff; the Ombudsman possesses statutory authority to initiate investigations on their own motion/volition without requiring an external complaint.
Compliance and Enforcement: The Ombudsman does not possess coercive judicial powers to issue criminal sentences, impose terms of imprisonment, or levy fines. Recommendations carry moral weight backed by reporting mechanisms and statutory deadlines (such as the requirement under the Official Information Act to comply within days).
Systemic Investigations and Oversight in Practice
Secure Facilities and OPCAT Inspections (Wakari Hospital):
Under its jurisdiction pursuant to the Optional Protocol to the Convention against Torture (OPCAT), the Ombudsman inspects places of detention, including secure psychiatric and intellectual disability facilities.
An inspection of a secure facility for intellectually disabled individuals with mental conditions at Wakari Hospital in Dunedin uncovered conditions falling far below international benchmarks (the United Nations Mandela Rules) and Health New Zealand guidelines.
Specific observed abuses included a patient being transported on an evacuation mat ("evac mat") due to mobility non-compliance and another patient subjected to solitary seclusion in a room for multiple years with negligible human contact.
Rather than delaying intervention for approximately 5 months to draft, peer-review, and clear natural justice processes for a formal report, the Chief Ombudsman immediately confronted the Chief Executives of Health New Zealand and the Ministry of Health.
Direct executive intervention resulted in the immediate closure of the offending ward and initiated an investigation across all secure intellectual disability facilities nationwide (approximately 5 facilities in total).
Incarceration of Wāhine Māori:
Māori women are severely overrepresented within the New Zealand penal system, comprising approximately 70% of the incarcerated female population.
Department of Corrections projections indicate that over the subsequent decade (projected to approximately 2036), the incarcerated population of Wāhine Māori will increase by an additional 80% or more on current levels.
To intervene systemically, the Ombudsman bypassed general public reporting and submitted a specialized report to Parliament's Justice Select Committee immediately prior to Scrutiny Week.
Scrutiny Week is an annual parliamentary mechanism during which all departments of the Crown, public sector Chief Executives, and Ministers are summoned before select committees and interrogated on performance and jurisdiction.
The report equipped select committee members to cross-examine department heads directly regarding ethnic disproportionality in the justice sector.
Local Government Oversight and Natural Disasters:
The Ombudsman oversees local government actions, heavily exemplified by administrative fallout following Cyclone Gabriel.
Teams investigated issues surrounding severe land degradation, property categorizations and zoning, and disputed insurance disbursements.
Educational Institutions and School Boards:
School boards are public bodies subject to the Ombudsman Act and Official Information Act, yet typically operate with limited administrative support (often relying on a single individual to process requests).
Ombudsman intervention frequently centers on disciplinary actions under the Education and Training Act, including the formal stand-down and suspension of students.
Oversight ensures boards adhere to administrative procedures and observe natural justice, granting students and their representatives adequate opportunities to participate.
The Ombudsman advises school boards against adopting overly legalistic approaches or unnecessarily hiring external lawyers, emphasizing the statutory mechanisms available to handle burdensome requests:
Refusing requests that require substantial collation and research, following consultations to narrow the scope.
Charging reasonable fees to recover processing costs.
Relying on statutory exemptions for frivolous and vexatious requests.
The Official Information Act (OIA) and Open Governance
Legislative Presumption and the Danks Committee:
Prior to the OIA, New Zealand operated under the Official Secrets Act, which enforced institutional secrecy.
The Danks Committee overturned this presumption, establishing that official information must be made progressively available unless conclusive or countervailing public interest reasons justify withholding.
Information requests must be decided and communicated within 20 working days or "as soon as reasonably practicable."
Personal Devices and Record-Keeping (Prime Minister's Office):
An ongoing investigation into Prime Minister Chris Luxon's office examined environmental policy information supplied by lobbyists to a senior ministerial adviser.
The information was stored on the adviser's personal device rather than official databases, accompanied by arguments that it fell outside the scope of the OIA.
Official information retains its legal character regardless of the physical storage medium or device upon which it is held, and public authorities must monitor, retrieve, and disclose such material when requested.
Anti-Transparency Workplace Culture (Ministry of Education):
A recorded staff hui within the Ministry of Education revealed officials advising colleagues not to record discussions in writing specifically to evade the Official Information Act ("don't write this down. We don't want the Official Information Act").
Deliberate omissions of decision-making foundations represent an institutional retreat toward pre-Danks secrecy, warranting systemic investigation into agency culture.
Adapting Common Law Standards to Modern Pressures:
Frivolous and Vexatious Thresholds: Under common law, establishing that a request is frivolous or vexatious requires a high bar that distinguishes strictly between the complainant and the complaint. In response to rising levels of unreasonable behavior, sovereign citizen campaigns, and self-represented litigants, the Ombudsman increasingly supports public agencies in using this provision to manage bad-faith disruption.
Protection of Officials Against Harassment: Common law historically presumed that the names and organizational roles of decision-makers within departments (such as the Ministry of Justice or Immigration New Zealand) should be publicly disclosed. Because automated data aggregation, artificial intelligence, and social media scraping expose officials to targeted harassment, threats, or improper inducements, the Ombudsman supports agencies withholding staff names to prevent harassment.
Institutional Challenges, Public Administration, and Reform
Root Causes of Public Sector Administrative Failure:
Administrative injustice rarely stems from malicious public servants; it primarily arises from structural inefficiencies, administrative silos, unverified assumptions about program success, and excessive risk aversion.
The public sector often misuses "pilots" and "fail-fast" frameworks as convenient, short-term funding alternatives, abandoning successful initiatives rather than providing long-term baseline funding.
The Legal Profession and the Rule of Law:
Society requires lawyers who think independently, advocate for vulnerable parties against administrative overreach, and defend the rule of law (under both thick and thin conceptions).
Legal practitioners must view the Ombudsman not as an afterthought, but as a primary, flexible, accessible, and cost-effective mechanism for client redress.
Procedural Fairness in Administrative Law: The Duty to Follow Procedure
The Primacy of Process in the Common Law:
Administrative law scrutinizes the executive along two axes: who possesses the power to decide (jurisdiction, lawful delegation, statutory authorization) and how that power is exercised (procedural legality).
The common law system is fundamentally process-focused, requiring decision-makers to adhere strictly to mandated procedures.
Port Louis Corporation: When the Governor-General of Mauritius altered municipal council boundaries, the council resigned to evade statutory consultation. The courts scrutinized procedural compliance thoroughly, demonstrating that statutory processes are mandatory and taken seriously by reviewing judges.
A concerning legislative trend involves statutes explicitly stating that a procedural failure does not render the ultimate decision unlawful (such as specific provisions in the Building Act).
Statutory Silence and the Presumption of Procedure:
Where an empowering statute grants administrative power to strip rights or property but remains completely silent regarding procedure, common law judges will imply the duty to act fairly.
Cooper v Wandsworth Board of Works (1863):
A builder, Cooper, erected a two-story structure in Wandsworth, England. Planning regulations required builders to provide the local Board of Works with 7 days' advance notice before commencing construction so drainage could be laid.
Cooper gave notice only 5 days prior to commencing construction. An inspector discovered the structure mid-construction, and the Board of Works demolished the building under an express statutory power to demolish unnotified works.
The Board of Works did not grant Cooper a hearing before demolition, arguing that the governing statute contained no procedural requirement for a hearing.
Cooper sued in trespass (analogous to the unlawful state entry in Entick v Carrington).
Justice Biles (Byles) established the foundational doctrine: "The common law will supply the omission of the legislature."
The court ruled that where an individual's rights or property are affected, the principles of natural justice are presumed to apply unless Parliament expressly excludes them in the legislation.
The Doctrine of Natural Justice: Origins, Revival, and Codification
The Twin Pillars of Natural Justice:
Natural justice does not signify abstract morality or vague notions of unfairness; it consists of two distinct, procedural common law principles derived from the adversarial justice system:
Audi alteram partem ("hear the other side"): The right to a fair hearing and the opportunity to present one's case before an adverse decision is made.
Nemo judex in causa sua ("no one shall be a judge in their own case"): The absolute rule against actual or apparent bias.
A third, related procedural ground is the doctrine of legitimate expectations: where a public authority represents that a specific process will be followed, it cannot deviate from that process without fair notice.
Revival in the Administrative State: Ridge v Baldwin (1964):
Following Cooper, the doctrine of natural justice lay largely dormant for approximately 80 years, narrowly restricted to judicial or quasi-judicial bodies exercising property-deprivation powers.
In Ridge v Baldwin (1964), the House of Lords resurrected Cooper to constrain the expanding post-war administrative state:
Ridge, the Chief Constable of Brighton, was prosecuted for conspiracy and corruption. He was acquitted at trial, but the trial judge criticized his professional conduct as corrupt and unfit for high office.
The local Watch Committee (headed by Baldwin) summarily dismissed Ridge under a nineteenth-century statute permitting the removal of police constables deemed negligent or unfit, providing him with no charge, no notice, and no hearing.
Ridge sought administrative relief not to regain his post, but to substitute his dismissal with a resignation to secure his police pension.
The House of Lords held that the dismissal was void for breach of natural justice.
Lord Morris established that before someone is condemned, they must receive an opportunity to defend themselves, requiring prior disclosure of the allegations, charges, or suggestions they must meet.
Ridge v Baldwin abolished the rigid distinction between judicial and administrative functions, confirming that natural justice applies to any public decision that deprives an individual of their rights, status, or office.
Codification Under the New Zealand Bill of Rights Act 1990 (NZBORA):
S27 of the NZBORA codifies the right to justice and the observance of natural justice by public tribunals and authorities.
Historically, courts distinguished S27 from the broader common law, interpreting S27 as applying solely to adjudicative bodies while common law applied across all public administration.
This distinction was critical because common law judicial review does not award monetary damages, whereas public law damages (Baigent's damages) can be granted for breaches of the Bill of Rights Act.
In the Combined Beneficiaries Union case, the courts harmonized these regimes, determining that common law natural justice and S27 of the NZBORA apply concurrently and govern public administrative decisions in the same manner.
Substantive Elements of the Right to a Hearing (Audi Alteram Partem)
Adequate Notice and the Burden of Service:
Natural justice requires that an affected individual receive sufficient, timely notice of an upcoming proceeding, detailing the subject matter and potential consequences.
The affirmative legal duty to ensure that notice is effectively served rests entirely on the public decision-maker, not the individual.
Moana Case (Moyang):
An immigration advisory panel determined that an applicant and her husband should be interviewed regarding their visa status.
The applicant's solicitor lost contact with the client after legal aid was declined and withdrew representation. The department could not locate the applicant, no interview occurred, and the Associate Minister cancelled the visa.
The court established two core holdings: once a decision-maker determines that natural justice requires a hearing or interview, that requirement cannot be abandoned; and the responsibility to ensure the interview occurs rests upon the decision-maker before a lawful adverse determination can be made.
Disclosure of Essential Information and Medical Evidence:
A fair hearing requires the disclosure of all material facts and expert reports relied upon by the decision-maker, enabling the individual to respond meaningfully.
Daganayasi v Minister of Immigration:
A Fijian mother sought to halt her deportation on the ground that her son suffered from a rare medical condition requiring specialist treatment unavailable in Fiji.
The immigration department appointed an independent medical referee, who reported that the child's condition had improved.
The Minister affirmed deportation, asserting that the best and most recent medical advice had been obtained, but failed to disclose the medical referee's report to the mother.
The child's treating specialist clinic was never consulted, depriving the applicant of the opportunity to challenge the referee's assessment with specialist evidence.
The Court of Appeal held that the failure to disclose the adverse medical referee report denied the applicant a meaningful hearing, rendering the deportation decision unlawful.
Disclosure of Adverse Preliminary Findings:
If an inquiry or investigative body forms tentative conclusions adverse to a party, it must disclose the underlying evidence and provisional findings prior to final determination to afford the party an opportunity to rebut them.
This rule applies heavily to inquiries by regulatory agencies such as the Commerce Commission and findings of inquiry commissions (as established in the Erebus Royal Commission litigation).
Oral Hearings vs. Paper Determinations:
There is no universal common law right to an oral hearing; in many administrative contexts, written representations satisfy procedural fairness (New Zealand Stock Exchange case: the immense financial scale of a transaction does not automatically compel an oral process).
Public authorities cannot implement blanket policies refusing oral hearings on grounds of administrative convenience, financial expense, or bureaucratic efficiency.
Osborne v Parole Board:
The court struck down a paper-only parole board policy, holding that a fair hearing cannot occur on paper alone where significant facts are disputed, personal credibility is at issue, mitigation requires oral presentation, or independent assessments of risk management are needed.
Evans Case:
An accused who had already pleaded guilty was denied the opportunity to address the judge orally during proceedings.
The High Court recognized that denying an oral address breached natural justice, but declined to grant relief because the guilty plea meant that an oral hearing would not have changed the outcome.
Legal Representation:
The right to a hearing does not confer an automatic right to legal representation before administrative tribunals.
A tribunal cannot impose a blanket ban refusing legal representation under any circumstances (Drew case under S27 of the NZBORA).
The Tarrant case establishes non-exhaustive criteria for determining when legal representation must be permitted to ensure procedural fairness:
The seriousness of the allegation and the severity of the potential penalty.
Whether complex points of law are involved.
The capacity of the individual to present their own case (considering age, education, and language).
The degree of procedural complexity.
The necessity for administrative speed.
The preservation of procedural fairness and equality between opposing parties.
Cross-Examination of Witnesses:
Cross-examination is not an inherent common law right in administrative decision-making.
Where material factual evidence is fiercely contested or the personal credibility of witnesses is determinative, natural justice requires permitting cross-examination.
The Duty to Give Reasons:
Under S23 of the Official Information Act 1982, New Zealand citizens and permanent residents possess an enforceable statutory right to receive written reasons for decisions made about them in their personal capacity.
Outside of specific statutory entitlements, the New Zealand common law does not recognize a universal, freestanding legal duty for public decision-makers to give reasons for their decisions.
Awatere Case:
The courts treat the provision of reasons as excellent administrative practice that prevents arbitrary governance and facilitates statutory appeals.
A failure to deliver reasons will not automatically invalidate a decision under common law judicial review unless reasons are required by statutory context or procedural fairness.
New Zealand Bill of Rights Act 1990: Framework, Characteristics, and the Hansen Approach
Constitutional Underpinnings and Characteristics of the New Zealand Bill of Rights Act 1990 (NZBORA):
Source and Origins: NZBORA is grounded in international human rights instruments, primarily the International Covenant on Civil and Political Rights (ICCPR).
Legal Status: It is an ordinary statute; it is neither supreme law nor entrenched under the New Zealand constitutional framework. Under s4, courts cannot hold any enactment invalid, ineffective, or unconstitutional, nor decline to apply any provision of an enactment, by reason only of inconsistency with NZBORA.
Substantive Rights Included: It affirms most fundamental civil and political rights (such as freedom of expression, freedom of movement, and freedom from discrimination), but completely omits second-generation (economic, social, and cultural) and third-generation (environmental, developmental) human rights.
Acceptable Shorthand and Exam Conventions: In academic legal writing for this topic, "NZBOR" or "NZBORA" are standard accepted abbreviations. Leading authorities may be referenced by single-word or short names (for example, Hansen, Atkinson, Fitzgerald, Taylor, or McAllister), whereas generic party names like Ministry of Health must be avoided as ambiguous. Terms such as declaration of inconsistency may be abbreviated as "DI" or "DOI".
The Six-Step Hansen Test for Legislative Inconsistency:
R v Hansen [2007] NZSC 7 sets out the authoritative methodology for New Zealand courts to analyze enactments alleged to breach human rights:
Step One (Natural Meaning): Ascertain the natural meaning of the contested legislative text. The natural meaning refers strictly to what the specific statutory words achieve and their precise operational effect, rather than the broad policy purpose of the overall Act. While the overall statutory purpose informs interpretation, meaning and purpose are distinct legal concepts.
Step Two (Prima Facie Inconsistency): Determine whether the natural meaning creates an apparent inconsistency with a protected right or freedom. If discrimination is alleged under s19, the test from Ministry of Health v Atkinson must be applied. For other rights (such as freedom of movement or assembly), inconsistency is evaluated from first principles. Even if an analyst considers that no inconsistency exists, the remaining steps must be worked through in alternative analysis.
Step Three (Justified Limitations / The Oakes Inquiry): Assess whether the prima facie limitation is demonstrably justified in a free and democratic society under s5 of NZBORA, applying the Canadian R v Oakes proportionality framework:
Sufficiently Important Objective: Does the legislative objective relate to concerns that are pressing and substantial?
Rational Connection: Is the limiting measure rationally connected to the objective, or is it arbitrary, unfair, or based on irrational considerations?
Minimal Impairment: Does the provision impair the right as little as reasonably possible to achieve the objective, or are less restrictive means available?
Overall Proportionality: Is there proportionality between the severity of the right's limitation and the legislative objective achieved?
Step Four (Outcome of S5): If the limit is demonstrably justified, the inquiry ends, and the natural meaning is adopted as rights-consistent.
Step Five (Alternative Meaning under S6): If the limit is not justified under s5, the court must determine under s6 whether an alternative, rights-consistent meaning is "reasonably possible". Under the orthodox Hansen standard, the alternative interpretation must be tenable, genuine, and not strained. However, decisions such as Fitzgerald v R suggest that courts may exercise expansive interpretative latitude to read down provisions or read in words to preserve consistency with protected rights.
Step Six (Resolution via S6 or S4): If a rights-consistent meaning is reasonably possible, it must be preferred. If no rights-consistent meaning is available without violating the clear intent and text of Parliament, s4 mandates that the natural meaning must be applied despite its inconsistency.
The Atkinson Test for Freedom from Discrimination (Section 19 NZBORA and the Human Rights Act 1993):
Under Ministry of Health v Atkinson [2012] NZCA 184, determining whether discrimination has occurred involves a two-part inquiry:
Step One: Differential Treatment on a Prohibited Ground: Identify whether the complainant is treated differently compared to an appropriate comparator group in an identical or analogous situation, based on a prohibited ground listed in s21 of the Human Rights Act 1993 (such as age, sex, disability, or marital status).
Step Two: Material Disadvantage: Determine whether that differential treatment results in a real, concrete disadvantage. The term "material" requires an actual burden, such as financial disparity, exclusion from social benefits, differential access to health services, or concrete loss of opportunity, rather than theoretical or trivial harm.
Direct vs. Indirect Discrimination: Direct discrimination occurs where the facial language or purpose of an enactment overtly draws distinctions based on a prohibited ground. Indirect discrimination (Quilter v Attorney-General) arises where a facially neutral rule or practice imposes an adverse, disproportionate impact upon a protected group.
Positive Discrimination (Affirmative Action): Differential treatment is not unlawful if it constitutes a genuine measure to advance groups disadvantaged by unlawful discrimination. To be legitimate, it must target an established disadvantaged group, work to correct a specific imbalance, and not create an indefinite or arbitrary status of preferential treatment.
Application to National Community Mentoring Scheme Bill (Clause 6 Case Study):
Statutory Setting: Clause 6 establishes eligibility criteria for appointment as a "community mentor" exclusively for persons between 58 and 85 years of age. Clause 9 grants substantial benefits to appointed mentors, including generous remuneration and priority access to state health and social initiatives. The Bill's stated objectives are providing experienced mentors to local communities and advancing the status and interests of elderly persons.
Step 1 (Natural Meaning): Clause 6 imposes a mandatory age qualification, strictly limiting mentor appointments—and consequently the lucrative benefits of clause 9—to the age bracket of 58 to 85 years.
Step 2 (Atkinson Test): Differential treatment exists between persons aged 58 to 85 and individuals willing and able to mentor who fall outside that age bracket (< 58 or > 85), based directly on the prohibited ground of age. Material disadvantage is established through complete exclusion from substantial financial pay and priority social/healthcare services. It cannot be sustained as positive discrimination, because individuals aged 58 to 85 are not categorically disadvantaged in a manner that justifies permanent preferential access, nor is the differential treatment temporary.
Step 3 (Oakes Proportionality Inquiry):
Objective: Deploying experienced individuals to mentor local communities is a sufficiently important objective.
Rational Connection: Highly tenuous. Although life experience correlates with age, experience and mentoring capacity are not categorically unique to those aged 58 to 85. Younger individuals possess valuable skills, and individuals aged 85 and older may retain full mental and physical capacity. The lower bound of 58 is arbitrary (drawing an irrational line between a 57-year-old and a 58-year-old).
Minimal Impairment: The objective could be achieved through age-neutral application processes and merit-based testing, or by widening the eligibility boundary (such as reducing the threshold to age 40). While courts often show deference to executive and legislative decisions involving financial expenditure and resource allocation, an absolute age barrier cannot be regarded as minimally impairing.
Overall Proportionality: Denying substantial economic and healthcare advantages to capable citizens based on arbitrary age bands is disproportionate to the statutory goal.
Step 5 and Step 6 (S6 and S4): The language of clause 6 is absolute, mandatory, and unambiguous. Reading in a judicial proviso (such as allowing exceptional applicants outside the age window) would conflict with the text and Parliament's specific wording. Consequently, no rights-consistent interpretation is reasonably possible under s6. S4 must apply, giving legal effect to the discriminatory natural meaning.
Reporting Obligations and Remedies for Legislative Breaches:
S7 Attorney-General Reporting: Under s7 of NZBORA, the Attorney-General is legally mandated to report to the House of Representatives upon the introduction of any bill that appears to impose an unjustified limit on a protected right.
Declarations of Inconsistency (DOI): Formal declarations that an enactment is inconsistent with NZBORA can be issued by the courts (Attorney-General v Taylor [2018] NZSC 104). S7A and 7B of NZBORA codify the downstream statutory procedure: following a final judicial declaration of inconsistency, the Attorney-General must present the declaration to the House of Representatives within a prescribed timetable, and the Government must formally respond to Parliament stating its legislative intentions.
Exclusivity of Declaratory Relief for Enactments: Common law damages, Baigent damages, and prerogative orders are unavailable against legislative provisions due to s4.
Human Rights Review Tribunal (HRRT): For breaches of the Human Rights Act 1993 outside direct primary legislation (including discrimination, sexual harassment, and privacy breaches), the HRRT possesses statutory jurisdiction to award damages, restraining orders, and declaratory relief.
Judicial Review Grounds: Illegality, Purpose, and Statutory Considerations
The Scope and Structure of Judicial Review:
Judicial review concerns supervision of executive power, evaluating who makes the decision, how the decision is made (procedural propriety, statutory preconditions, natural justice, bias, and legitimate expectations), why the decision is made (illegality, improper purpose, relevant and irrelevant considerations), and what substantive decision was made (unreasonableness).
Jurisdictional Roots: Under Anisminic Ltd v Foreign Compensation Commission [1969] 2 AC 147, any material error of law made by an administrative decision-maker causes them to exceed their statutory jurisdiction, rendering the resulting determination a nullity.
The Wednesbury Structuring: Associated Provincial Picture Houses Ltd v Wednesbury Corporation [1948] 1 KB 223 establishes that public authorities must remain within the "four corners of the Act". A decision is illegal if made for an improper purpose, if irrelevant considerations are taken into account, or if mandatory relevant considerations are omitted.
Doctrine of Improper Purpose:
Statutory powers conferred for a specific public purpose cannot be lawfully deployed to achieve an extraneous, collateral, or unauthorized objective.
Quinlan v Wellington City Council: Wellington City Council intended to construct the Wellington cable car. Lacking immediate authority under local government legislation, and seeking to bypass the formal ministerial approvals mandated by the Tramways Act, the council used generic statutory powers intended for elevators and public works to seize Ms. Quinlan's land and deny her planning permission. The court held this was an improper purpose; powers designed for elevators could not be used to construct a tramway or restrict private building plans ahead of an unapproved tramway scheme.
Padfield v Minister of Agriculture, Fisheries and Food [1968] AC 997: Under the Milk Marketing Board scheme, milk prices and regional transport subsidies were fixed nationally. Producers in certain regions suffered disproportionate financial losses due to shifting transport costs. The governing Act permitted producers to lodge complaints with the Minister, who had discretion to refer disputes to a statutory committee of investigation. The Minister refused to refer the complaint, motivated by a desire to avoid political embarrassment and unfavorable committee findings. The House of Lords held this to be an improper purpose; the discretion to refer complaints was frustrated for political self-interest rather than advancing the policy of the enactment.
Lower Hutt City Council: A local authority attempted to close a public street relying on ordinary proprietary ownership rights. The court held that the council must use the specific, formal statutory street-closure mechanisms rather than relying on its status as landowner for an improper purpose.
Pub Charity: The Gambling Commission exercised statutory powers to suspend gaming machine (pokie) licenses as a punitive sanction against an operator. The court held that statutory suspension powers were granted for remediation and regulatory compliance, not for punishment; utilizing them punitively constituted an improper purpose.
Relevant Considerations:
A decision-maker must consider all mandatory factors and exclude unauthorized matters. Relevant considerations are categorized as:
Statutory Mandatory Considerations: Explicitly specified in the empowering enactment. In school disciplinary cases, a board of trustees suspending a student must consider statutory factors, such as whether a suspension can be lifted or whether the alleged conduct was actually committed; failing to record and demonstrate consideration of these points renders the suspension unlawful.
Statute-Implied Considerations: Factors that the court infers must be considered based on the subject matter, scope, and purpose of the statute. In Simes, a barrister was deregistered from legal aid work by the Legal Services Agency based on an audit report containing both positive commendations and negative criticisms. The agency based its decision exclusively on the negative elements. The court held that where an authority commissions an audit report, it is an implied mandatory consideration to weigh the report in its entirety, including positive findings; selective focus on negative elements invalidated the decision.
International Treaties as Implied Considerations: Under New Zealand's dualist legal structure, unincorporated international treaties do not form part of domestic law without statutory enactment. However, entering into international conventions creates an obligation for executive decision-makers to treat treaty standards as mandatory relevant considerations. In deportation proceedings, executive obligations under the United Nations Convention on the Rights of the Child (UNCRC) require the best interests of dependent children in New Zealand to be actively considered; an administrative failure to evaluate the position of dependent children invalidates a deportation order.
Contextual Mandatory Considerations: Arise from the specific factual and commercial reality of a decision. In Thames Valley Electric Power Board v P环境中 (NZ), an electric power board undertaking corporatization and share allocation failed to consider the distinct position of a capital-intensive pulp and paper mill that consumed approximately 80% of the district's electric power. The court determined that omitting the unique profile of a dominant industrial consumer was an omission of an essential relevant consideration.
Te Tiriti o Waitangi as a Relevant Consideration:
Even where an empowering statute lacks an express "Treaty clause", administrative law requires decision-makers to treat Te Tiriti o Waitangi / the Treaty of Waitangi as an essential relevant consideration whenever the subject matter touches upon Māori interests, taonga, or customary rights. The Treaty is an organic constitutional instrument that colors all executive matters to which it has relevance.
Huakina Development Trust v Wellington Water Board [1987] 2 NZLR 188: Customary and spiritual Māori values (tikanga, metaphysical relationship to water bodies) are relevant considerations in planning and water-discharge licensing decisions under general environmental statutes.
New Zealand Maori Council v Attorney-General (Radio Frequencies) [1991]: Executive allocation of radio spectrum frequencies required substantive and active consideration of Waitangi Tribunal recommendations concerning the preservation of Te Reo Māori under the Treaty principle of active protection, prior to privatizing or licensing spectrum assets.
Ngāi Tahu (Whale Watching, Kaikōura): The Director-General of Conservation sought to issue additional commercial whale-watching permits in Kaikōura to third-party commercial operators. Ngāi Tahu challenged the action on the basis that the Crown failed to consider their customary rights under Article 2 of the Treaty (guaranteeing undisturbed possession of fisheries, estates, and taonga). The Court of Appeal ruled that while the Treaty does not grant an absolute veto power to Māori, it requires the Crown to give active, meaningful protection to Ngāi Tahu's prior investments and commercial enterprise in the whale-watching industry. The failure to give Ngāi Tahu's Article 2 interests substantial weight in the permit-allocation process rendered the executive decision unlawful.
Irrelevant Considerations:
A public body exceeds its authority if it takes into account considerations that are legally impermissible, extraneous, or contrary to the scheme of the empowering statute.
Fiordland Venison: The governing game meat regulations established five clear statutory criteria for granting processing licenses (applicant suitability, historical compliance, premises suitability, sanitary fitness for purpose, and impact on existing licensed processors). The Minister declined a license application on the ground that the government wished to limit the number of commercial operators and restrict overall game hunting capacity. The court held that because the statutory list was exhaustive, economic rationalization and industry restriction were irrelevant considerations that the Minister was prohibited from considering.
District Court Legal Aid Allocation: A District Court refused to grant legal aid to an accused person based on administrative budgetary constraints and an assessment of the seriousness of the charge. The Legal Services statute mandated that legal aid grants be determined solely by "the interests of justice". The court held that internal departmental budgetary deficits are extraneous to the interests of justice, making reliance on financial resources an irrelevant consideration that voided the refusal.
Interchangeability and Legal Realism: In administrative law practice, categories of illegality frequently overlap. An irrelevant consideration can often be framed as an improper purpose, or vice versa (as seen in Quinlan). Litigators routinely plead improper purpose, failure to take into account relevant considerations, and reliance on irrelevant considerations concurrently.
Subjectivity and Roberts v Hopwood [1925] AC 578: The Poplar Borough Council resolved to pay all municipal employees a minimum wage of 4 pounds per week, deliberately paying equal wages to female workers and male workers performing identical labor. The House of Lords struck down the decision as ultra vires and unlawful, holding that the council had breached its fiduciary duty to rate-paying citizens. Lord Atkinson described the council's decision as being driven by an irrelevant consideration: "eccentric principles of socialistic philanthropy" and a "feminist ambition to secure equality of the sexes in the world of labour". The council members were surcharged and imprisoned for non-compliance. This authority serves as a structural warning regarding the subjective, value-laden nature of judicial determinations of what constitutes an "irrelevant" consideration.
Substantive Review, Unreasonableness Standards, and Intensity of Review
Substantive Review and Constitutional Restraint:
Substantive review interrogates the substance or merits of the final decision itself (the "what" question), rather than procedural legality (the "how" or "why").
Constitutional Difficulties: Substantive review creates acute tension with democratic principles and parliamentary sovereignty. Administrative decision-makers are vested with statutory discretion by Parliament and are politically accountable. Judges are unelected and lack technical, commercial, and financial expertise in complex policy areas (such as municipal rating, resource management, or pharmaceutical subsidies). Unlike civil law jurisdictions (France's Conseil d'État, Germany) or modern England (which has a dedicated Administrative Court within the High Court), New Zealand has no specialist administrative courts or specialist administrative judges.
Two Avenues of Substantive Review in New Zealand: Direct breach of NZBORA by an executive body (which allows the substantive decision to be invalidated), and common law unreasonableness.
The Wednesbury Unreasonableness Doctrine:
Associated Provincial Picture Houses Ltd v Wednesbury Corporation [1948] 1 KB 223: Wednesbury Borough Council granted a Sunday cinema license on the express statutory condition that "no children under the age of fifteen years shall be admitted to any entertainment, whether accompanied by an adult or not". The cinema owners challenged the condition as ultra vires and unreasonable.
The Standard: Lord Greene MR held that the court can only intervene if an administrative decision is "so absurd that no sensible person could ever dream that it lay within the powers of the authority", or "so unreasonable that no reasonable authority could ever have come to it".
The Red-Haired School Teacher: Lord Greene MR introduced the hypothetical example of a municipal teacher dismissed solely because she had red hair. Such a dismissal would be so irrational and perverse that no sensible body could ever contemplate it falling within their legal authority. There was no actual teacher with red hair in Wednesbury; it was an illustrative legal metaphor demonstrating the exceptionally high threshold required for unreasonableness.
Non-Stand-Alone Character: Pure unreasonableness rarely stands alone. A decision so irrational that no reasonable body could make it almost invariably suffers from underlying illegality, bias, procedural unfairness, or reliance on irrelevant considerations.
Modern Expansion and Structuring of Substantive Review:
Substantive Unfairness: In Thames Valley Electric Power Board, Cooke P recognized "substantive unfairness" as an independent head of review, bridging the gap between procedural error and pure irrationality.
Justice Thomas's Framework in Waitakere City Council v Lovelock [1997] 2 NZLR 385: The Court of Appeal attempted to lower and structure the high Wednesbury standard, identifying specific operational indicators of substantive unreasonableness:
A decision that is manifestly disproportionate.
A failure to give sufficient weight to a fundamental common law right or human value.
A clear logical flaw or contradiction in the underlying reasoning.
A failure to comply with a public body's fiduciary duty to its constituents.
An unreasonable failure to balance the competing interests of disparate community groups.
Variable Intensity of Review ("Hard Look"): The scrutiny applied by courts fluctuates according to context. Decisions involving fundamental civil rights, personal liberty, or statutory discrimination receive intensive review ("hard look" scrutiny, as seen in Discount Brands Ltd v Westfield (NZ) Ltd regarding planning consents and commercial impacts). Conversely, decisions involving macro-economic policy, broad public resource allocation, or technical resource consents (Ports of Auckland) attract a highly deferential, "light-touch" standard of review.
Unreasonableness Categories in Modern Jurisprudence:
Disproportionality of Outcome: In Laruer, a professional rugby player received a -to--month suspension following an in-game disciplinary infraction. The court held the outcome to be substantively unreasonable because the severity of the sanction was grossly disproportionate when measured against established domestic and international sporting penalties.
Inconsistency with Statutory Scheme / Failure to Accommodate Exceptions: In R (Rogers) v Swindon NHS Trust [2006] EWCA Civ 392, a health authority refused to fund the breast cancer drug Herceptin for a patient under a blanket financial rationing policy. While the empowering statute permitted the trust to restrict funding, the policy recognized that funding could be granted in "exceptional cases". The court held that the trust's refusal was substantively unreasonable because its policy provided no rational, medical definition of what constituted an exceptional case, operating as an unlawful blanket ban.
Frustration of Statutory Objects: In the 2003 Urban Māori Fisheries Allocation case, regulations established a settlement trust fund for urban Māori following the Treaty of Waitangi fisheries settlement. The trustees imposed rules excluding certain urban groups from accessing industry training grants. The court held these exclusions unreasonable because restricting access to educational training directly frustrated the overarching statutory purpose of the fisheries settlement.
Fiduciary Duty and Public Rating Cases:
Local councils and public authorities owe an implied fiduciary duty to their ratepayers and taxpayers to act with commercial prudence, balance budgets responsibly, and refrain from imposing unnecessary financial extractions.
Prescott v Birmingham Corporation [1955] Ch 210: Birmingham Corporation had statutory authority to run municipal transport and charge "such fares as they may see fit". The council introduced a scheme offering completely free bus travel to old-age pensioners. The court invalidated the policy, holding that the statutory power to vary fares did not authorize waiving fares entirely for a specific demographic, because the council had breached its fiduciary duty to ratepayers by conferring a municipal subsidy without statutory authorization.
Mackenzie District Council (Hydro-Dam Taxation): Following the corporatization of the state electricity sector, hydro-electric generation dams in the Mackenzie Basin were transferred to state-owned enterprise (SOE) Electricorp. Under standard rating valuation mechanisms, Mackenzie District Council—a rural authority serving a sparse population—received an unprecedented municipal rating windfall of approximately . Electricorp challenged the assessment. The High Court intervened under substantive unreasonableness and fiduciary duty, ordering the council to reduce the tax levy because the local authority possessed no genuine infrastructure need for such an extreme surplus.
The Retraction in Wellington City Council v Woolworths New Zealand Ltd (No 2) [1996] 2 NZLR 537: The Mackenzie precedent triggered widespread litigation across New Zealand, with commercial ratepayers challenging municipal differential rates. Woolworths challenged Wellington City Council's rate differential, which levied significantly higher commercial rates than residential rates. The Court of Appeal reversed the trend, firmly shutting the door on judicial rate-setting and retreating to traditional Wednesbury unreasonableness. Richardson P held that municipal rating allocations involve political, social, and economic choices committed by Parliament to elected local representatives; the courts will only intervene if a rating system is so irrational that no reasonable council could ever have enacted it. Mackenzie was isolated as an exceptional case involving an extraordinary, unbudgeted rating windfall.
Public Law and Judicial Review Remedies
Fundamental Principles Governing Public Law Relief:
Discretionary Nature: All remedies in judicial review are discretionary. Even if an applicant establishes an error of law, natural justice breach, or substantive unreasonableness, the High Court may refuse relief based on delay, applicant conduct, administrative disruption, or overriding public policy considerations (codified under the Judicial Review Procedure Act 2016).
No General Damages at Common Law: Damages are unavailable for judicial review at common law. Because the courts and the executive are constitutional branches of the indivisible Crown, the common law did not permit the Crown to impose a financial penalty upon itself. Monetary compensation is available only if the claimant establishes an independent private law cause of action (for example, tortious trespass where statutory authority is absent, as in Entick v Carrington [1765]) or public law compensation under NZBORA (Simpson v Attorney-General [Baigent's case] [1994] 3 NZLR 667).
Prerogative Orders (Common Law Writs):
Certiorari (Quashing Order): The court quashes and nullifies an unlawful decision. Certiorari does not dictate what the ultimate outcome must be; the administrative decision-maker retains jurisdiction to re-take the decision, provided they apply correct legal procedures, exclude irrelevant considerations, and comply with the law. In Rogers (Herceptin), the decision was quashed, leaving the trust free to reconsider the application under a lawful policy framework.
Mandamus (Mandatory Order): Compels a public official or administrative body to perform a public or statutory duty that they have neglected, refused, or failed to discharge.
Prohibition (Prohibiting Order): Prohibits an administrative decision-maker from proceeding with an unlawful course of action, continuing an ultra vires inquiry, or exceeding their jurisdiction.
Statutory Reform: Judicial Review Procedure Act 2016:
Prior to the Judicature Amendment Act 1972, applicants were required to plead specific common law prerogative writs individually, creating severe procedural pitfalls. The Judicature Amendment Act 1972 and its modern successor, the Judicial Review Procedure Act 2016 (JRPA), streamlined public law litigation into a unified "application for review".
Under s16 and s18 of the Judicial Review Procedure Act 2016, an applicant can seek review of statutory powers of decision and request any combination of quashing orders, mandatory directions, declarations, or injunctions.
Where an applicant seeks to challenge the exercise of non-statutory executive powers (such as the exercise of the royal prerogative or contractual actions by state entities that fall outside the JRPA definition of a statutory power), they must still rely directly on the common law prerogative remedies.
Ordinary Civil Remedies in Administrative Law:
Injunctions: An order restraining a body from committing an unlawful act or compelling an act. Injunctions remain subject to state immunity limitations when directly targeting the Crown.
Declarations: The declaration is the most common remedy in administrative law. A declaration authoritatively states the legal rights of the parties and pronounces whether an executive act is lawful or unlawful. It carries no coercive power (it cannot be executed via bailiffs or contempt proceedings). Courts favor declarations against public authorities because constitutional comity assumes the executive will voluntarily comply with an authoritative judicial statement of the law. This practice avoids constitutional confrontations regarding whether the courts can issue coercive sanctions against the Crown (M v Home Office [1994] 1 AC 377; Minister of Foreign Affairs v Poll).
