How to appeal a DA decision in NSW (Land & Environment Court)
Had a development application refused, conditioned harshly, or sitting undetermined in NSW? An applicant can appeal to the Land and Environment Court for a fresh merits review. This guide explains the Class 1 appeal, the deadlines, where objectors stand, and what a strong submission needs.
⏰ Appeal deadlines are strict
A Class 1 merits appeal is generally brought within 6 months of the determination or deemed refusal. Confirm the exact period for your matter — it's strict.
Appeal rights in New South Wales
After a council determines a development application, an applicant can appeal the determination to the Land and Environment Court for a merits review (a Class 1 appeal) under the Environmental Planning and Assessment Act 1979. The Court re-considers the DA on its planning merits.
If you're the applicant
An applicant can appeal a refusal, the conditions imposed, or a deemed refusal (where the council hasn't determined the DA within the statutory period).
If you objected
Objectors generally do NOT have merit appeal rights in NSW (designated development is the main exception). For objectors, the submission stage during exhibition is the key opportunity — see the objection guide.
How to appeal — step by step
- 1Confirm you have an appeal right
Applicant appeals cover refusals, conditions and deemed refusals. If you objected, check whether the development is 'designated development' — otherwise a merit appeal generally isn't available to you.
- 2Note the deadline
A Class 1 appeal is generally brought within 6 months of the determination (or the deemed refusal). Confirm the exact period for your matter — don't let it lapse.
- 3Commence the appeal in the Court
File the Class 1 application with the Court, identifying the DA, the determination and the grounds of appeal.
- 4Prepare your planning case
Frame the case against the LEP, DCP and any SEPP, test the proposal against the controls, and cite comparable LEC decisions. The Court runs on planning merits and evidence.
- 5Conciliation and hearing
Many Class 1 matters go to a s.34 conciliation conference first; if not resolved, a hearing follows. A well-organised planning submission helps at both stages.
What a strong the Land and Environment Court submission needs
- A clear statement of the planning grounds — not a list of complaints, but the scheme provisions the decision turns on
- The proposal tested against the actual controls (zone, overlays, and the residential / amenity standards)
- Comparable tribunal decisions in point — how the tribunal has treated similar proposals before
- A focused, well-organised written submission the tribunal member can follow

Appealing in New South Wales — FAQ
Can an objector appeal a DA approval in NSW?
Generally no — third-party merit appeals are limited to designated development. For most objectors, the submission during public exhibition is the main opportunity to influence the outcome, which is why getting it right matters so much.
What is a deemed refusal?
If the council doesn't determine the DA within the statutory period, it's treated as a refusal you can appeal — you don't have to wait indefinitely for a determination.
What is a s.34 conciliation conference?
A without-prejudice conference run by a Commissioner to try to resolve the appeal by agreement (often with amended plans). A clear planning submission helps you negotiate from strength.
What does a submission cost?
Our LEC submission is $399 (instant), framing your planning case for the Court. Fixed, published price — no 'request a quote'.
