Chapter 1: Case Overview and Core Disputes

Basic Information

Court of Hearing: Land and Environment Court of New South Wales (Class 1)

Presiding Judge: Bradbury AC (Acting Commissioner)

Cause of Action: Appeal against a development control order requiring demolition (order appeal under Environmental Planning and Assessment Act 1979 (NSW))

Judgment Date: 28 October 2021

Core Keywords:

Keyword 1: Authentic Judgment Case

Keyword 2: Development control order

Keyword 3: Unauthorised building works

Keyword 4: Secondary dwelling characterisation

Keyword 5: Procedural fairness under Schedule 5

Keyword 6: Building Information Certificate and compliance timeframe

Background

The Respondent local council was investigating an unrelated complaint about a neighbouring property when its officer noticed a separate structure in the rear yard of the Applicants’ residential land. The council’s subsequent checks showed there was no development consent authorising that structure. The council then issued an order requiring the structure to be demolished, services disconnected, and the slab removed. The Applicants, as owners of the land, challenged that order in the Land and Environment Court.

This dispute was not about a minor paperwork error. It was a contest between two competing realities: the council’s enforcement obligation to respond to a building erected without consent, and the Applicants’ practical wish to keep the structure and regularise it through proper approvals rather than immediate demolition.

Core Disputes and Claims

What the Court was required to determine was not whether the structure existed or whether consent was missing. Those matters were effectively conceded. The central legal focus was the proper discretionary outcome on an appeal: should the order stand as drafted, be revoked, or be modified, and if modified, on what terms and with what compliance timeframe.

Applicants’ position (relief sought in substance):

1. Revocation of the demolition order, or a result that avoids immediate demolition.
2. Recognition that the structure was said to be used for storage rather than habitation.
3. A pathway to lodge applications to legalise the structure and use it going forward.

Respondent’s position:

1. Confirmation that the order was lawfully made and procedurally fair.
2. Maintenance of enforcement action given the absence of consent and concerns about compliance with building standards.
3. Resistance to any outcome that would allow an unlawful dwelling-type structure to remain indefinitely without proper certification and approvals.

Chapter 2: Origin of the Case

The relationship between the parties began in the most ordinary way that planning disputes often do: a resident complains, the council investigates, and the enforcement lens widens beyond the initial complaint.

The Applicants owned a residential lot in an R2 Low Density Residential zone. At some point years earlier, a separate building had been erected in the rear yard. Whatever the Applicants’ reasons for constructing it, the structure was not supported by development consent.

The decisive moment came when the council officer, present next door for another investigation, saw the rear-yard structure from outside the Applicants’ land. That visual observation triggered council checks, which confirmed no consent existed for the building. From there, the administrative machinery of enforcement moved quickly: a notice of intention to issue an order was served, the Applicants made written representations, and the council then issued a formal development control order requiring demolition and associated works.

In human terms, the conflict escalated because each side viewed the same structure through a different lens.

• For the council, it was a compliance risk: a building that looked capable of residential occupation, erected without assessment against planning controls or building standards.
• For the Applicants, it was part of their property’s “everyday utility”, framed as storage and, in their mind, something that should be capable of being resolved through approval processes rather than demolition.

That mismatch in framing fed the litigation: once an enforcement order is issued, owners often feel the bulldozer is already idling at the kerb, even though the planning system still provides pathways to seek certification and consent.

Chapter 3: Key Evidence and Core Disputes

Applicants’ Main Evidence and Arguments

1. The notice and order history, including their written representations to council.
2. Email correspondence between the Applicants and the council concerning the order process.
3. Photographs and material lodged with the Class 1 application showing the structure and items stored inside.
4. A short letter from a consulting engineer asserting the building was structurally sound and compliant with nominated standards and the National Construction Code, expressed in a brief “to whom it may concern” style.

Key arguments advanced by the Applicants:

• The order was made “without proper investigation and procedure”, including that the council officer did not enter their land.
• The building was said not to be a “granny flat” or residential accommodation, but storage.
• The council allegedly failed to consider their representations.
• They were allegedly not given an opportunity to fix the situation by applying for approvals and a Building Information Certificate.
• The structure was asserted to be structurally sound and not harmful to neighbours or the environment.

Respondent’s Main Evidence and Arguments

1. Council documents supporting the enforcement decision, including the notice of proposed order and the final order.
2. Investigation notes by the council officer recording the enforcement process and consideration of representations.
3. An expert report and oral evidence from a senior building surveyor employed by the council, including a sketch of the building and observations from inspection.

Key arguments advanced by the Respondent:

• The statutory preconditions for the order were met: a building requiring approval was erected without approval.
• The order process complied with the procedural fairness requirements in Schedule 5 of the Environmental Planning and Assessment Act 1979 (NSW).
• The structure, by its internal fit-out, was properly characterised as a dwelling and therefore a secondary dwelling in planning terms.
• Even if used as storage, it was not exempt development under the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008.
• The Applicants’ engineering letter was inadequate to establish structural adequacy, and there were specific concerns observed on inspection (including issues relating to the slab).

Core Dispute Points

1. Procedural fairness: whether the council followed the Schedule 5 notice and consideration requirements, and whether not entering the land undermined the lawfulness of the process.
2. Characterisation: whether the structure was a dwelling or merely storage, and why that distinction mattered under the zoning controls and exempt development rules.
3. Exempt development: whether the structure could fit within the Codes SEPP concept of a garden shed and, if so, whether size thresholds were exceeded.
4. Structural adequacy: whether the Applicants’ evidence was sufficient to neutralise safety/compliance concerns.
5. Discretionary outcome: whether the demolition order should be enforced immediately, or modified to give time to pursue a Building Information Certificate and development consent.

Chapter 4: Statements in Affidavits

This matter illustrates a practical reality of self-prepared or self-managed litigation: parties often provide documents that resemble affidavits in purpose, even if they do not read like professionally drafted sworn evidence.

The Applicants’ narrative style focused on perceived unfairness in process, and on an asserted practical truth: “it is storage, not a dwelling”. Their materials sought to persuade by common-sense framing rather than by tight alignment to the statutory elements that matter most in a development control order appeal.

The council’s approach, by contrast, was methodical and enforcement-oriented. Its evidence aligned to the legal architecture:

• Identify the statutory source of power for the order.
• Prove the jurisdictional facts: building erected without consent, owners served, notice procedure followed.
• Provide expert observations that support characterisation and justify enforcement urgency, including safety concerns.
• Address the Applicants’ representations by pointing to the documentary record of consideration.

In-depth comparison: the same fact told in two ways

Same fact: “What is this structure in the backyard?”

• Applicants’ framing: a storage building, implying the regulatory burden should be lighter and the enforcement response disproportionate.
• Council’s framing: a building containing features of a self-contained living space, implying residential capability and therefore a more serious planning and building control concern.

The boundary between “untruths and facts” in this case did not turn on an allegation of deliberate lying. It turned on a more common litigation fault line: people describe a structure by how they wish it to be perceived (use intention), whereas planning law often asks what it is capable of being used for, viewed objectively, and what approvals were required regardless of asserted use.

Strategic Intent behind procedural directions

The Court’s procedural management in this appeal had a clear objective: test the Applicants’ objections against the statutory framework and evidence chain rather than allowing the dispute to drift into generalised grievance about council conduct.

A conciliation conference was arranged, which served two strategic functions:

1. It created a chance for pragmatic resolution, including inspection and discussion of a compliance pathway.
2. It generated clearer evidence about what the building contained and how it should be characterised.

---

Chapter 5: Court Orders

Prior to final hearing, the procedural pathway included:

1. Service of a notice of intention to issue a development control order, including a draft order and a stated compliance period.
2. An opportunity for the Applicants to make written representations about why the order should not be made, or about its terms and compliance timeframe.
3. The issuing of the development control order requiring demolition and associated disconnection/removal works.
4. Listing and conduct of a conciliation conference under the Land and Environment Court Act 1979 (NSW), which did not resolve the matter.
5. Listing for hearing, with council calling oral evidence from its building surveyor, including cross-examination.

---

Chapter 6: Hearing Scene: Ultimate Showdown of Evidence and Logic

The hearing was structurally simple but evidentially decisive. The statutory basis for an order existed and was largely uncontested. The real contest was whether the Applicants’ complaints about process, characterisation, and fairness justified revocation, or whether the proper outcome was a tailored modification that balanced enforcement with a realistic compliance pathway.

Process Reconstruction: Live Restoration

The Applicants’ representative cross-examined the council’s building surveyor. The most important contest points were:

1. What did the building actually contain and look like on inspection?
2. Could the building plausibly be treated as exempt development, like a garden shed?
3. Were there observable building-standard concerns that made the Applicants’ brief engineering letter insufficient?
4. Was the council’s enforcement process procedurally fair under the statutory scheme?

The evidentiary pivot was that the Applicants did not call oral evidence to contradict the surveyor’s observations about internal fit-out. That meant the Court was left with a largely unchallenged description: bathroom facilities, a kitchen fit-out, bedrooms, and living space. In planning disputes, capability and adaptation matter. A building with the physical ingredients of separate residential occupation is difficult to downplay as mere storage when the objective features point the other way.

Core Evidence Confrontation

The most decisive evidence was:

• The surveyor’s inspection observations describing residential-style fit-out.
• Photographs showing a variety of stored goods not associated with gardening, undermining the “garden shed” framing.
• The size estimate of the structure, placing it well above the typical exempt development threshold for a small shed.
• The council officer’s investigation notes demonstrating that the Applicants’ representations were at least considered before the order was issued.
• The Applicants’ short engineering letter, contrasted with the council’s explanation of why meaningful structural adequacy assessment requires more detail and, sometimes, destructive testing.

Judicial Reasoning with Original Quotation

Context: The Applicants argued they were denied procedural fairness and that the council did not follow proper process.

“I find that the Council has complied with those requirements.”

Why that statement mattered: It signalled that the Court treated Schedule 5 as the governing procedural code. Once compliance with that code was found, the Applicants’ fairness complaint largely collapsed, and the dispute moved to discretionary modification rather than revocation.

Context: The Applicants framed the building as storage; the council said it was capable of separate residential occupation.

“I am satisfied that the facilities … render the Building capable of being occupied … as a separate domicile.”

Why that statement mattered: Planning characterisation is often anchored to capability. By finding the structure was capable of separate occupation, the Court anchored the building’s planning significance as more than a casual shed-like structure, making enforcement logically justified even if the Applicants asserted a different use intention.

---

Chapter 7: Final Judgment of the Court

The Court upheld the appeal in the sense that it did not leave the order untouched. It modified the order rather than revoking it.

The operative result was:

1. The development control order remained in force but was varied.
2. Terminology was corrected so that references to “granny flat” were replaced with “secondary dwelling”.
3. The compliance date was extended to allow time for the Applicants to pursue two formal pathways:
   • development consent for the use of the secondary dwelling; and
   • a Building Information Certificate under Div 6.7 of Part 6 of the Environmental Planning and Assessment Act 1979 (NSW).
4. The modified order preserved demolition as the end point if approvals were not obtained within the extended timeframe.
5. The Applicants were given liberty to apply to extend time further where reasonable steps had been taken.

This outcome is best understood as “enforcement with a measured off-ramp”: the structure remained unlawful at the date of judgment, but the Court adjusted the order to make compliance practically achievable without unnecessary immediate demolition where regularisation might be possible.

Chapter 8: In-depth Analysis of the Judgment: How Law and Evidence Lay the Foundation for Victory

Special Analysis

This case carries an instructive jurisprudential value in the way it shows the Land and Environment Court’s practical use of discretion on an order appeal. The Court did not treat enforcement as a binary switch of “demolish” versus “do nothing”. Instead, it treated the appeal power as a tool to calibrate compliance to reality, while holding firm to legality: a building erected without consent remains unlawful unless and until approvals are obtained.

The judgment also illustrates a quiet but important principle: procedural fairness in this statutory context is not an open-ended moral inquiry. It is, to a significant extent, codified. If the enforcement authority follows the statutory notice and representation scheme, fairness will usually be treated as satisfied, unless something exceptional is shown.

Judgment Points

1. A concession on the core illegality narrows the field.
   The Applicants did not meaningfully dispute the jurisdictional facts: the building required consent and consent was absent. That meant the “battlefield” became discretionary outcome, not foundational legality.

2. Procedural fairness was treated as compliance with the statutory code, not as an invitation to re-litigate council investigation style.
   The Applicants criticised the council officer for not entering the land. The Court treated this as legally irrelevant where the statutory notice and representation requirements were met and observation from an adjoining property was possible.

3. Characterisation was driven by objective features and capability, not asserted intent.
   The building’s internal configuration was determinative. A bathroom, kitchen facilities, bedrooms, and living area are not neutral details. They are strong indicators of a separate domicile.

4. Exempt development arguments fail quickly when size and fit are wrong.
   Even if “shed-like” labels are applied, the Codes SEPP contains specific categories and thresholds. Once the Court accepted the evidence that the structure did not fit the relevant category and exceeded size limits, exempt development was effectively off the table.

5. Structural adequacy is not proved by a bare conclusion.
   The Applicants’ engineering letter lacked detail, timing, methodology, and the kind of reasoning that would satisfy a certifier or council in a Building Information Certificate process.

6. Discretion was exercised to allow a legalisation pathway without surrendering enforcement.
   The Court acknowledged that the structure had existed for years and that, if approvals could be obtained, demolition would be unnecessary. That led to a compliance extension tied to concrete milestones: consent and a Building Information Certificate.

7. Precision in terminology matters in enforcement instruments.
   Replacing “granny flat” with “secondary dwelling” was not cosmetic. It aligned the order with the planning language that governs assessment and reduces ambiguity about what is being regulated.

8. Liberty to apply is a safeguard for genuine compliance efforts.
   The Court built a practical safety valve into the orders: if the Applicants take real steps but need more time, they can seek an extension rather than be forced into demolition by an unrealistic deadline.

Legal Basis

The Court’s reasoning operated within a clear statutory scaffold:

• Power to issue an order requiring demolition where a building requiring approval is erected without approval, under the development control order regime in the Environmental Planning and Assessment Act 1979 (NSW).
• Procedural fairness and notice requirements governed by Schedule 5 of that Act, including the notice of proposed order and the opportunity to make representations.
• The Court’s appeal powers on an order appeal, allowing revocation, modification, substitution, and compliance directions.
• Planning characterisation under the applicable local environmental plan definitions, including “dwelling” and “secondary dwelling”.
• Exempt development assessment under the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008, including category fit and maximum floor area thresholds.
• Building Information Certificate pathway under Div 6.7 of Part 6 of the Environmental Planning and Assessment Act 1979 (NSW), which is a practical route to address building compliance where a structure already exists.

Evidence Chain

Each decisive conclusion can be expressed as: Conclusion = Evidence + Statutory Provisions.

Victory Point 1: The order-making foundation was established.

• Evidence: Absence of development consent for the structure; ownership of the land by the Applicants; existence of the building.
• Statutory provisions: Order power for unauthorised building erection; order appeal discretion.
• Result: The Court treated demolition enforcement as justified in principle.

Victory Point 2: Procedural fairness was satisfied.

• Evidence: Notice of proposed order served; draft order provided; compliance period specified; representations invited; representations made; investigation notes recorded consideration.
• Statutory provisions: Schedule 5 procedure; deeming effect where requirements met.
• Result: The fairness challenge did not justify revocation.

Victory Point 3: Characterisation as a dwelling-type structure was supported.

• Evidence: Inspection observations of bathroom, kitchen facilities, bedrooms, living room; capability for separate occupation.
• Statutory provisions: Local plan definitions of dwelling and secondary dwelling.
• Result: The structure was treated as at least capable of being a separate domicile.

Victory Point 4: Exempt development was rejected on category and scale.

• Evidence: Stored items not garden-related; structure not apt to be a garden shed; floor area estimated around 60 m2; size not disputed.
• Statutory provisions: Codes SEPP exempt categories and maximum floor area.
• Result: Consent was required regardless of asserted storage use.

Victory Point 5: Structural adequacy was not established by the Applicants.

• Evidence: A brief engineering letter without inspection date, methodology, or reasoning; council surveyor concerns about slab and construction features.
• Statutory provisions: Practical requirements of certification processes, including the type of information expected for a Building Information Certificate.
• Result: The Applicants did not prove the structure was structurally adequate for the purpose of revoking enforcement.

Victory Point 6: Modification was justified by practical compliance fairness.

• Evidence: The building existed for several years; Applicants expressed willingness to apply for consent and a certificate; belief (even if mistaken) that the order prevented applications.
• Statutory provisions: Court power to modify an order and to make orders about compliance.
• Result: The Court extended time and linked compliance to obtaining consent and a certificate.

Victory Point 7: Enforcement remained real, not symbolic.

• Evidence: Compliance was still mandatory unless approvals were obtained.
• Statutory provisions: Order framework and compliance powers.
• Result: The modified order kept demolition as the default consequence if legalisation failed.

Judicial Original Quotation

Context: The Court addressed the Applicants’ view that they were not given a chance to seek approvals while the order existed.

“The Applicants could … have done either … at any time.”

Why that statement mattered: It clarifies that, legally, an order does not freeze the planning system. Owners can pursue approvals even while an order exists. The Court used this to reject revocation as unnecessary, while still recognising that extending time was a practical, proportionate response.

Context: The Court explained why the Applicants’ engineering material did not carry the weight they claimed.

“A more detailed report will be required.”

Why that statement mattered: It set expectations for what “proof” looks like in building compliance contexts. A bare assurance is not a substitute for structured expert reasoning that addresses concealed elements, standards, and inspection limitations.

Analysis of the Losing Party’s Failure

The Applicants did not “lose” in the blunt sense of having their appeal dismissed, but their main thrust — revocation and a finding that the order was wrongly made — largely failed. The reasons were practical and instructive:

1. Misalignment between arguments and statutory tests.
   Complaints about investigation style did not defeat a codified Schedule 5 process where notice and representations were given and considered.

2. Lack of contradictory evidence on key factual points.
   The council’s inspection evidence about internal fit-out was effectively unchallenged by oral testimony. Without competing evidence, the Court had little basis to accept the “storage only” framing as decisive.

3. Over-reliance on conclusory engineering material.
   The Applicants’ letter did not contain the detail needed to establish structural adequacy, especially where the council raised specific concerns about slab construction and moisture protection.

4. Underestimating the role of capability and adaptation in planning characterisation.
   In planning law, a structure’s capability to be used as a separate domicile can matter more than the owner’s asserted present use.

5. Treating revocation as the only “fair” outcome.
   The Court demonstrated that fairness can be achieved through modification and compliance pathways, without surrendering the integrity of enforcement.

Implications

1. If you build first and seek approval later, the legal risk tends to be relatively high.
   The planning system is designed for assessment before construction. Retrospective pathways exist, but they are not guaranteed, and they often require stronger evidence than people expect.

2. Fairness in statutory enforcement often looks like process compliance, not personal reassurance.
   Even if you feel unheard, the Court will ask: were you notified, invited to respond, and was your response considered? If yes, fairness arguments may have limited traction.

3. How a building is fitted out can matter as much as what you call it.
   A structure with the fittings of a separate home will likely be treated more seriously than a simple shed, even if you say you are using it for storage today.

4. The best defence is a credible evidence chain, not a single letter.
   If you need to prove structural adequacy, commission a detailed report that explains inspections, standards applied, limitations, and reasoning.

5. Courts can be practical without being permissive.
   A modification that gives time for approvals can be a humane outcome, but it is still anchored in a strict principle: if approvals fail, demolition remains on the table.

Q&A Session

Q1: If I receive a demolition order, can I still apply for development consent or a Building Information Certificate?

A1: In many cases, yes. The existence of an order does not necessarily prevent you from lodging applications. However, the timing and strategic approach matter, and you should act quickly because orders often have strict compliance deadlines.

Q2: Does calling a building a “storage shed” avoid the need for development consent?

A2: Not automatically. Exempt development rules are specific and threshold-driven. If the structure does not fit within the prescribed category or exceeds size limits, development consent may still be required, even if you only store items inside.

Q3: What kind of evidence is usually needed to persuade a council to issue a Building Information Certificate?

A3: Typically, detailed building compliance evidence is required. That often includes a comprehensive engineering or building survey report addressing the relevant standards, identifying what was inspected, how concealed elements were assessed, and why the building is structurally adequate and compliant, acknowledging any limitations.

2. Self-examination of Core Statutory Elements

⑤ Property, Construction and Planning Law

Core Test (Statutory Warranties)

Was the work performed in a proper and workmanlike manner? Were the materials supplied good and suitable for the purpose?

Practical application to cases of this kind:

1. Identify what work was actually carried out.
   This includes slab works, framing, waterproofing, cladding, roof structure, wet area installation, plumbing and electrical fit-out, and any drainage works.

2. Identify what standards the work should meet.
   Relevant benchmarks can include the National Construction Code requirements, relevant Australian Standards, and any local authority requirements relevant to certification.

3. Examine whether the work shows signs of departure from proper and workmanlike construction.
   Indicators can include poor compaction, inadequate moisture barriers, questionable fixings, insufficient bracing, and visible defects in concrete or framing.

4. Assess whether materials and systems were suitable for the purpose.
   Suitability is assessed against expected performance, durability, and safety, not merely whether the structure is still standing.

5. Compile evidence capable of persuading a decision-maker.
   A brief assertion tends to be insufficient. A report should explain the inspection method, the tests performed, limitations, and reasoning.

Risk warning in non-absolute language:
Even where a structure appears stable, the risk of adverse findings tends to be relatively high if concealed elements cannot be properly verified or if documentation is incomplete.

Core Test (Defects)

Is it a Major Defect (6-year statutory warranty) or a Minor Defect (2-year statutory warranty)? Does the defect render the building uninhabitable or cause the destruction of the building?

Practical application to unauthorised structure disputes:

1. Identify defects and classify them.
   Major defects often relate to structural performance, waterproofing failures in a way that threatens integrity, or systemic non-compliance.

2. Determine whether defects affect habitability or structural safety.
   Even in a planning enforcement setting, perceived structural risks can make it harder to obtain certification.

3. Consider evidence limitations.
   Retrospective inspections often face constraints because key elements are concealed. That limitation should be addressed transparently.

Risk warning:
Where an unauthorised structure includes wet areas and a slab, defects relating to moisture management and waterproofing tend to be treated as higher risk and may require extensive evidence to overcome.

Core Test (Planning)

Have the conditions of the Development Application (DA) or Complying Development Certificate (CDC) been breached?

Practical application to retrospective approval and enforcement matters:

1. Determine whether any approval exists.
   If no consent exists, the question becomes whether consent was required and whether any exempt or complying pathway applied.

2. Identify the planning controls applicable to the land.
   This includes zoning, permissible uses, development standards, and definitions relevant to “dwelling” or “secondary dwelling”.

3. Test exempt development eligibility strictly.
   Exempt development categories are narrow. The structure must fit the category and satisfy all standards, including size thresholds.

4. Consider pathways for regularisation.
   A development application may be possible, but success depends on compliance with planning controls and whether impacts can be acceptably managed.

Risk warning:
Retrospective approval tends to involve relatively high uncertainty where the structure is large, capable of occupation, or raises safety compliance questions.

---

3. Equitable Remedies and Alternative Claims

This dispute is primarily statutory planning enforcement, but alternative legal concepts may become relevant in the broader dispute ecology, particularly if the matter expands into loss allocation or reliance-based arguments.

Promissory / Proprietary Estoppel

Did the other party make a clear and unequivocal promise or representation? Did you act in detrimental reliance? Would it be unconscionable for them to resile?

Practical relevance here:
– Estoppel is rarely a direct shield against statutory planning enforcement by a public authority. However, if an owner relied on a clear written assurance by an authority that consent was unnecessary, an argument might be explored in relation to fairness, legitimate expectations, or public law remedies, though outcomes tend to be uncertain and highly fact-specific.

Risk warning:
Even where an official is said to have made informal comments, courts tend to be cautious about treating that as a basis to defeat statutory compliance obligations.

Unjust Enrichment / Constructive Trust

Has the other party received a benefit at your expense? Is it against conscience for them to retain it?

Practical relevance here:
– In planning disputes, these doctrines are more commonly seen in private disputes between co-owners, builders, or neighbours, rather than as a direct defence to enforcement. They may arise if there are separate claims about who paid for construction or who should bear demolition and rectification costs.

Risk warning:
Where the dispute is fundamentally regulatory, equity doctrines tend to be peripheral and may not provide a reliable pathway to avoid compliance.

Procedural Fairness

Did the decision-maker afford natural justice? Was there an opportunity to be heard? Was there apprehended bias?

Practical relevance here:
– Procedural fairness is central to order-making. If statutory notice requirements are not met, a fairness challenge tends to have stronger prospects.
– If the statutory code is complied with, the prospects of a successful fairness challenge tend to reduce significantly unless a distinct unfairness is demonstrated.

Risk warning:
A general sense of unfairness, without identifying a procedural step that was missed or legally inadequate, tends to be a weaker foundation for relief.

---

4. Access Thresholds and Exceptional Circumstances

Regular Thresholds

In planning enforcement order contexts, key “hard” indicators often include:

1. Was development consent required for the building or use?
2. Is there an applicable exempt development pathway, and are all criteria satisfied?
3. Was the statutory notice and representation process followed?
4. Is there credible evidence of structural adequacy and compliance sufficient for certification processes?
5. Has the owner taken timely steps to regularise the development?

Exceptional Channels

Even where consent was required and missing, exceptional considerations can influence discretionary outcomes:

1. Time and settled circumstances.
   A structure existing for years may support an argument for a realistic compliance pathway rather than immediate demolition, although it does not legalise the structure.

2. Genuine steps toward compliance.
   Courts tend to look more favourably on owners who promptly engage experts, lodge applications, and cooperate with inspection and information requests.

3. Clear capacity for lawful approval.
   If there is a credible case that a development application and Building Information Certificate could succeed, modification of timing can be a practical outcome.

Suggestion:
Do not abandon a potential pathway to regularise a structure simply because an order has been issued. Compare your circumstances against the planning controls and certification requirements, and act quickly, because the compliance clock usually continues to run.

---

5. Guidelines for Judicial and Legal Citation

Citation Angle

It is recommended to cite this case in legal submissions or debates involving:

1. The scope of the Land and Environment Court’s discretion on an appeal against a development control order.
2. The practical application of Schedule 5 procedural fairness requirements in development control orders.
3. The planning characterisation of a structure based on capability for separate occupation rather than asserted use intention.
4. The Court’s willingness to modify an order to allow time for Building Information Certificate and development consent pathways while preserving demolition as a consequence if regularisation fails.

Citation Method

As Positive Support:
– When your matter involves an unauthorised building erected without consent, and the issue is whether an order should be modified to provide a realistic compliance pathway tied to specific approval milestones, this authority can support an argument for conditional time extension rather than revocation.

As a Distinguishing Reference:
– If the opposing party cites this case to argue that modification should always be granted, you should emphasise the factual differences, such as stronger evidence of structural adequacy, clearer exempt development eligibility, or materially different impacts, to argue the discretionary balance should be struck differently.

Anonymisation Rule

When recounting the reasoning for public-facing summaries, avoid real party names and use procedural titles such as Applicants and Respondent, while retaining the case name and citation in formal legal citation contexts.

---

Conclusion

This case shows how planning enforcement disputes are often won or lost on discipline: discipline in following the statutory procedure, discipline in building a coherent evidence chain, and discipline in asking the Court for a remedy that fits the legal reality.

The golden sentence:
Everyone needs to understand the law and see the world through the lens of law. The in-depth analysis of this authentic judgment is intended to help everyone gradually establish a new legal mindset: True self-protection stems from the early understanding and mastery of legal rules.
