## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Planning & Environment](https://ailawframework.com/practice/planning-and-environment.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | From the consent, record whether it writes a lapsing period of less than 5 years, and whether the period has already expired. If both are still open on the face of the consent, record that an application for an extension of 1 year may be made before the period expires, and that the consent authority may grant it if satisfied the applicant has shown good cause. Record that an extension, if granted, runs from the later of the date the consent would have lapsed and the date the extension was granted, or the date an appeal determination allowed it. Record that the section does not apply to complying development. Do not draft the application. Do not say that good cause has been shown. |
| What the lawyer must review | The lawyer decides whether to apply and what good cause is put forward. Section 4.54 of the Environmental Planning and Assessment Act 1979 (NSW) applies where, in granting a development consent, the consent authority reduced the lapsing period to less than 5 years. The applicant, or any other person entitled to act on the consent, may apply to the consent authority before the period expires for an extension of 1 year. The consent authority may grant the extension if satisfied the applicant has shown good cause. The opened text has no subsection (3). An extension runs from the later of the date the consent would have lapsed but for the extension, and the date the consent authority granted it or, if the Court allowed the extension in determining an appeal, the date the Court determined the appeal. The Act's definition of Court was not opened. The section does not apply to complying development. This task does not prepare the application. |

## Checking plan

**Source-by-source verification**

Trace relied-on content to independent sources and check for relevant material the output has missed.

- What the AI does: From the consent, record whether it writes a lapsing period of less than 5 years, and whether the period has already expired. If both are still open on the face of the consent, record that an application for an extension of 1 year may be made before the period expires, and that the consent authority may grant it if satisfied the applicant has shown good cause. Record that an extension, if granted, runs from the later of the date the consent would have lapsed and the date the extension was granted, or the date an appeal determination allowed it. Record that the section does not apply to complying development. Do not draft the application. Do not say that good cause has been shown.

- Who reviews: Responsible lawyer with competence in the matter
- Basis: Practical workflow informed by the linked primary sources; the traffic light and working checks are editorial guidance, not a court classification.
- Why: The level reflects what the work is, the consequence of an error, and how much of the output the lawyer must independently re-derive.

## Checks the lawyer makes

1. Do not treat a consent that still has a 5-year period as eligible.
2. Do not draft the extension application or the good-cause reasons.
3. Do not invent a subsection (3). The opened text goes from subsection (2) to subsection (4).
4. Record that the section does not apply to complying development.

## Notes

- These are suggested working checks. Confirm the required checking with the responsible lawyer before work starts; the checking approach does not establish permission to use AI.
