Factual and Procedural Background
The Plaintiff applied to Company B on 16 June 2023 for planning permission to change the use of a residential property to a recreational camping site comprising six cabins (gross floor area stated as 180 m2), a gravel access path, a wastewater treatment system and ancillary works. Water supply was from an existing well. The proposed operation was "car-free" with guest access primarily by water taxi to a jetty on the site; a Natura impact statement was submitted. The site (stated area 0.410 ha) is located approximately 6.2 km north of The City on the western shore of a local lake and is served by an existing gated vehicular access onto a designated Strategic Route (referred to in the decision as The Road).
Company B granted permission on 2 February 2024 with a condition requiring access to the glamping units to be in accordance with the car-free proposals. Two third parties (Notice Party 1 and Notice Party 2) appealed the grant to Company A. An inspector was appointed, conducted an external site inspection, and reported that it had not been adequately demonstrated that the car-free proposal would prevent intensification of use of the existing entrance onto the Strategic Route. Company A, following the inspector's recommendation, refused permission by order dated 20 March 2025.
The Plaintiff commenced judicial review proceedings on 6 May 2025 seeking certiorari quashing Company A's order and related reliefs. Ex parte leave was granted on 26 May 2025. The judicial review hearing occurred on 3 March and resumed on 27 April 2026. Judgment was delivered by Judge Humphreys on 8 May 2026, dismissing the proceedings.
Legal Issues Presented
- Whether Company A lawfully determined the application on its merits or impermissibly presumed the Plaintiff would not operate the development in accordance with the plans and particulars (including the car-free access arrangements).
- Whether Company A's decision was irrational, unreasonable or took into account irrelevant considerations by treating the proposal as requiring vehicular access and applying development plan objectives for Strategic Routes.
- Whether Company A breached fair procedures or failed to give adequate reasons for concluding that the proposed development would, in practice, require car access.
- Whether the enforceability and workability of the proposed car-free operation were legitimate and determinative planning considerations for Company A in refusing permission.
Arguments of the Parties
Plaintiff's Arguments
- The application, submissions and updated NIS made clear the proposal was car-free with arrivals/departures by water taxi, public transport, walking or cycling; letters of support from water transport providers were included.
- Company A improperly refused to decide the application on its merits by presuming the Plaintiff would not comply with the car-free operation and by effectively rejecting an application not before it (i.e. vehicular access).
- The question of compliance with any access stipulation is an enforcement matter for the local planning authority and not properly determinative of the grant of permission.
- Company A failed to give adequate reasons and acted contrary to fair procedures by effectively disbelieving the Plaintiff without adequate basis.
Respondent's (Company A) Arguments
- Company A and the inspector expressly considered the car-free proposals and alternative transport arrangements; the decision and inspector's report show the submissions were addressed.
- In assessing the planning merits the inspector and Company A were entitled to evaluate the likely practical operation and effects of the proposal; enforceability and workability are legitimate planning considerations.
- Objective CDP11.14 (policy for Strategic Routes) was a relevant consideration because, if the proposal would in practice lead to car-based access, the effects on The Road were properly assessable.
- The decision contained adequate reasons when read with the inspector's report; the challenge is in substance a merits-based disagreement that does not establish illegality.

Court's Reasoning and Analysis
The court began by emphasising settled principles: judicial review addresses legality not merits, and the Plaintiff bears the onus of proof to show illegality. The court identified the central factual/legal axis as whether Company A lawfully assessed the workability and enforceability of the Plaintiff's car-free proposal, including whether the Commission could reasonably conclude the proposal would, in practice, result in intensified use of the existing vehicular entrance onto the Strategic Route and thereby conflict with the relevant development plan objective (CDP11.14).
The court analysed the inspector's report and Company A's decision, noting that the inspector expressly recorded the car-free proposals and assessed transport matters (§§7.7–7.14), concluding it had not been adequately demonstrated that the proposal would avoid intensification of use of the entrance. The court applied established authority that conditions and permissions must be workable and enforceable and that decision‑takers may lawfully evaluate whether a proposal can practicably operate as submitted.
Applying those principles, the court found Company A's concerns about the practicality and enforceability of the car-free arrangements to be legitimate and rational. The court rejected the Plaintiff's contention that assessment of workability impermissibly trespassed into enforcement functions, holding instead that enforceability is a proper planning consideration and that a red line around part of the property did not preclude assessment of how the development would integrate with the surrounding environment.
The court addressed each core ground (presumption of non-compliance; failure to decide on merits; irrationality/irrelevant considerations; fair procedures; inadequate reasons) and concluded that each amounted, in substance, to a merits-based disagreement. The inspector's evaluative judgments about proximate services, likely guest behaviour, and traffic implications were held to be lawful, non-speculative assessments. The court found no failure to give adequate reasons when the decision is read holistically with the inspector's report.
Ultimately, the Plaintiff had not discharged the onus to show that Company A's decision fell outside the range of lawfully open options; the refusal was within the Commission's evaluative discretion.
Holding and Implications
DISMISSED
Holding: The court dismissed the judicial review proceedings and ordered that the dismissal be perfected forthwith with no order as to costs unless any party applies otherwise within the times and in the manner specified in the judgment (with opportunities for written submissions on costs and a further listing to confirm the order).
Implications: The direct effect is to uphold Company A's refusal of permission. The judgment reiterates established principles (onus on applicant; distinction between legality and merits; relevance of workability and enforceability) but does not purport to create novel legal precedent beyond applying existing authority to the facts of this case.
