## Key facts

| Practice area | [Defamation & Media Law](https://ailawframework.com/practice/defamation-and-media-law.md) |
| Human involvement | Yellow: Lawyer and AI draft together |
| How AI is used | From the capture log, list each publication date, the forum the lawyer names, and the date that falls one year later for a California libel or slander claim. Show the count. Name no other state's period. |
| What the lawyer must review | You pick the accrual date and the forum. California Code of Civil Procedure § 340(c) requires an action for libel or slander to be brought within one year. Other states set their own periods. A federal filing still uses the state period that applies. Rule 11 reaches the date you put in a federal pleading. Opinion 512: you check the arithmetic. |

## Checking plan

- What the AI does: From the capture log, list each publication date, the forum the lawyer names, and the date that falls one year later for a California libel or slander claim. Show the count. Name no other state's period.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- The one-year figure is California § 340(c). Do not use it for another state.
- Tolling, the discovery rule and republication are state-law questions. The table does not decide them.
