| Practice area | [Privacy, Data Protection & Cyber](https://ailawframework.com/practice/privacy-data-protection-and-cyber.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | From the form or script the lawyer supplies, mark whether the requester is being treated as an authorised recipient, whether the individual is told the law, the purpose, that refusal is not an offence, and the consequences of refusal, and whether any later use matches a purpose the guide allows. Flag a request to use the number to prove identity, as a general identifier, or for matching that is not authorised. The tool does not collect or store a tax file number. |
| What the lawyer must review | The lawyer decides whether the organisation may ask for the number, approves the collection wording, and decides any incidental number already received. |

## 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 form or script the lawyer supplies, mark whether the requester is being treated as an authorised recipient, whether the individual is told the law, the purpose, that refusal is not an offence, and the consequences of refusal, and whether any later use matches a purpose the guide allows. Flag a request to use the number to prove identity, as a general identifier, or for matching that is not authorised. The tool does not collect or store a tax file number.
- What the lawyer does: The lawyer decides whether the organisation may ask for the number, approves the collection wording, and decides any incidental number 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 the collection text names the authorising law, the purpose, that it is not an offence to refuse, and the consequences of refusal.
2. Confirm the number is not used to prove identity for a financial institution, as a national identifier, or for matching, unless the guide’s authorising laws apply.
3. For a number received incidentally, record that it must not be used or recorded inconsistently with the rule, and that destruction or de-identification applies when the number is no longer required, subject to the Archives Act point for a Commonwealth record.

## 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.
