## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Class Actions / Representative Proceedings](https://ailawframework.com/practice/class-actions-representative-proceedings.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | List, from the sample files, the facts that differ from file to file on how a loss is calculated. Do not choose a methodology. |
| What the lawyer must review | You decide whether the differences are common questions and what method, if any, can be used. Federal Rule of Civil Procedure 23(a)(2) requires questions of law or fact common to the class before members may sue as representatives. A list of differences is not that decision. Formal Opinion 512: check each point against the sample file. Model Rule 1.6: claimant files do not go into a public tool. |

## Checking plan

- What the AI does: List, from the sample files, the facts that differ from file to file on how a loss is calculated. Do not choose a methodology.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- The list shows differences in the samples. It does not decide that a common method exists.
- Rule 23(a) has four prerequisites. Common questions are only one of them.
