| What the lawyer must review | The lawyer decides which items to contest and on what basis, drafts the responding affidavit with the deponent, and checks every reference. |

## Checking plan

**Lawyer-led judgement**

The lawyer makes the substantive assessment. Any permitted AI assistance remains supporting work with its own checks.

- What the AI does: From the other side’s Costs Summary and the file, list each claimed item and stage with the work the file shows was done, mark items that appear excessive, duplicated or outside the costs order, and tabulate the differences. The tool writes nothing in the responding affidavit.
- What the lawyer does: The lawyer decides which items to contest and on what basis, drafts the responding affidavit with the deponent, and checks every reference.
- 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.
- Restriction: The lawyer makes the substantive assessment. Any permitted AI assistance remains supporting work with its own checks.

## Checks the lawyer makes

1. Confirm the material (including produced and subpoenaed documents subject to the implied undertaking or any confidentiality order) may go into the tool before it is used.
2. Check each contested item against the costs order’s scope.
3. Check every reference to the other side’s summary.
4. Confirm the filing date in the timetable.

## 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.
