## Checking plan

**Line-by-line review**

Review the complete output at the level of each line, paragraph or clause; check facts, meaning and omissions.

- What the AI does: From the lodged document, the due diligence record and the new information, list each statement affected, each new circumstance, and the corresponding passage, and draft the supplementary or replacement wording with a verification reference for each change, for the lawyer to rework.
- What the lawyer does: The lawyer decides whether the matter is materially adverse, whether a supplementary or a replacement document is appropriate, settles every line and its verification, and decides the consequences for applicants already received.
- 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. Confirm unannounced, price-sensitive deal information goes only into a tool approved for inside information and is handled under the deal’s information barrier.
2. Verify every new statement against the due diligence record.
3. Decide materiality with the due diligence committee, not the tool.
4. Confirm the applicant-consequences analysis before lodgment.

## 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.
