## 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 and the application the lawyer has marked, record that a development consent which authorises the erection of a building, but not the use of the building once erected, is sufficient to authorise the use of the building when erected for the purpose for which it was erected, if that purpose was specified in the application. Record that this does not authorise occupation of the building if an occupation certificate is required before occupation. Do not decide that the purpose was specified. Do not decide that occupation can start. |
| What the lawyer must review | The lawyer decides whether the consent is an erection consent, whether the purpose was specified, and whether occupation can start. Section 4.19 of the Environmental Planning and Assessment Act 1979 (NSW) says a development consent that authorises the erection of a building, but not the use of the building once erected, is sufficient to authorise the use of the building when erected for the purpose for which it was erected if that purpose was specified in the application for development consent. The section does not authorise the occupation of such a building if Part 6 requires an occupation certificate to be issued. The definitions section was not opened. A separate task checks whether use can start without an occupation certificate. This task does not apply that check and does not decide that occupation can start. |

## 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 and the application the lawyer has marked, record that a development consent which authorises the erection of a building, but not the use of the building once erected, is sufficient to authorise the use of the building when erected for the purpose for which it was erected, if that purpose was specified in the application. Record that this does not authorise occupation of the building if an occupation certificate is required before occupation. Do not decide that the purpose was specified. Do not decide that occupation can start.
- What the lawyer does: The lawyer decides whether the consent is an erection consent, whether the purpose was specified, and whether occupation can start. Section 4.19 of the Environmental Planning and Assessment Act 1979 (NSW) says a development consent that authorises the erection of a building, but not the use of the building once erected, is sufficient to authorise the use of the building when erected for the purpose for which it was erected if that purpose was specified in the application for development consent. The section does not authorise the occupation of such a building if Part 6 requires an occupation certificate to be issued. The definitions section was not opened. A separate task checks whether use can start without an occupation certificate. This task does not apply that check and does not decide that occupation can start.
- 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. Copy the consent and the purpose only as they appear in the papers the lawyer has marked.
2. Keep both sentences: the use that is authorised, and the occupation that is not.
3. Do not decide that the purpose was specified or that occupation can start.

## 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.
