# Stop a judging rule

POST

/v1/projects/{projectId}/judging-rules/{ruleId}/unregister

```sh
curl --request POST \
  --url https://example.com/v1/projects/example/judging-rules/example/unregister \
  --header 'Authorization: Bearer <token>'
```

It queues nothing more; its versions and the items it queued stay. `unregistered: false` when it was already stopped. Needs `write` on the project.
