Checklist for complying with the LEC Gen AI practice note and the UCPR expert code: restricted material, permitted uses, affidavit disclosures, verifying citations, and leave before planning, heritage or ecology experts use Gen AI.

## Key facts

- Kind: Checklist. Steps or checks to work through and tick off.
- Practice area: [Planning & Environment](https://ailawframework.com/precedents/planning-and-environment.md)
- Jurisdictions: New South Wales
- AI level: Red. Keep AI out of the decisive steps. A lawyer does the work.
- Law stated as at: 2026-10-17
- Status: Maintained. Checked on 2026-10-17 against the 4 authorities it cites, for New South Wales.

## When to use it

Use at the start of every LEC matter and again before filing affidavits, expert reports or submissions. Give the objector section to community objectors and other self-represented participants who prepare statements.

## How AI may be used

Lawyer-led compliance task. AI may help track the checklist, but it must not generate evidence, and verification of citations must not be done solely by AI.

**AI may:**

- Maintain the matter's AI-use register and remind the team of checklist steps.
- Prepare chronologies, indexes and document summaries permitted by para 9B, from material that is not restricted.
- Draft submissions for a lawyer to verify citation by citation.

**AI must not:**

- Must not generate, edit or rephrase the content of affidavits, witness statements or objector statements.
- Must not draft any part of an expert report without the Court's prior leave.
- Must not be used as the only check that cited authorities exist and are accurate.

**The lawyer checks:**

- Every affidavit and witness statement contains the required Gen AI disclosure.
- Every expert has received the practice note and the UCPR code, and any Gen AI use has prior leave.
- Submissions contain the verification statement and the citations were checked by a person against the source.
