Planning appeals and expert evidence — scales of justice composition

When a planning matter becomes contested

A refusal, a deemed refusal or a set of conditions you cannot live with is rarely the end of the road — but it is a decision point. A contested planning matter is not resolved by simply arguing harder. The best pathway usually depends on understanding the real issues in contention, whether the proposal can be amended, and how the planning merits should be presented.

Greiss Planning works with owners, developers and their legal teams to review the application history, council's reasons for refusal and the relevant planning controls, and to give a clear, frank assessment of the options before time and money are committed to any one course.

Your options after a refusal

  • Section 8.2 review of determination — asking the council to review its own decision under the Environmental Planning and Assessment Act, often supported by amended plans; usually faster and less costly than court.
  • Amended application — addressing the reasons for refusal directly and lodging a revised proposal.
  • Land & Environment Court appeal (Class 1 merit appeal) — an independent re-hearing of the application. Strict time limits apply; in general terms an appeal must be commenced within six months of the determination, and deadlines should always be confirmed with a lawyer.
  • Negotiation and conciliation — many Class 1 appeals resolve at a section 34 conciliation conference, where amended plans and agreed conditions can settle the dispute without a full hearing.

What we provide

  • A merit review of the refusal or disputed conditions against the planning controls.
  • Strategy advice on which pathway — review, amendment, negotiation or appeal — best fits the matter.
  • Preparation of amended plans, supporting statements and additional information.
  • Expert planning evidence for contested proceedings, prepared to the court's expert witness requirements.
  • Support through conciliation conferences and without-prejudice discussions with council.

How Greiss Planning helps

  1. Review the matter — we examine the application history, the reasons for refusal or the disputed conditions, and the relevant planning controls.
  2. Give you a frank view — a clear assessment of the planning merits, the realistic pathways and the risks of each, before you commit to any course.
  3. Prepare the material — amended plans and documentation, a section 8.2 review submission, or expert planning evidence, depending on the pathway chosen.
  4. Support the resolution — working alongside your legal team through conciliation, negotiation or hearing until the matter is determined.

Frequently asked questions

My DA was refused — what are my options?

You generally have four pathways: ask the council to review its own decision under section 8.2, lodge an amended application that addresses the reasons for refusal, commence a Class 1 merit appeal in the Land & Environment Court, or negotiate — often through conciliation. The right choice depends on the planning merits, so an early frank review is worth doing before committing to any pathway.

What is a s8.2 review versus a court appeal?

A section 8.2 review asks the council itself to reconsider its determination, usually with amended plans — it is faster and cheaper, but the decision stays with the council. A Class 1 appeal is an independent merit re-hearing before the Land & Environment Court. Some applicants pursue a review first and keep the appeal pathway in reserve, subject to time limits.

How long do I have to appeal a refusal in NSW?

In general terms, a Class 1 merit appeal against a refusal must be commenced within six months of the determination. Different limits can apply in particular circumstances, and lodging a review does not always pause the clock. Deadlines are strict and missing one can end the pathway entirely, so we recommend confirming the applicable time limit with a lawyer early.

What does an expert planning witness do?

An expert planning witness gives the court an independent professional opinion on the planning merits — how the proposal performs against the controls and the issues in contention. The duty is to the court, not the client, and evidence is usually prepared jointly with the other side's expert to narrow the real issues before the hearing.

Do I need a lawyer as well as a planner?

For court proceedings, usually yes. A planner addresses the planning merits and evidence; procedure, advocacy and legal advice are a lawyer's domain, and legal questions should always be directed to one. Greiss Planning routinely works alongside solicitors and barristers as part of the appeal team, and can do so from the earliest strategy discussions.

Is it worth appealing?

Honestly, it depends on the merits. Some refusals rest on issues that amended plans or better evidence can resolve; others reflect fundamental conflicts with the controls that no appeal is likely to overcome. We give a frank view of the prospects first — including advising against an appeal where the merits are weak — so you can decide with clear eyes.
