# Enable Case Nullification
Learn how to configure your Vault to enable Case nullification.
## About the Feature
Support for Case Nullification was added in 22R1. Vaults created in 22R2 or later include the necessary configuration by default, while Vaults originally deployed earlier than 22R1 must have the configuration upgrades described on this page to enable this feature.
This feature allows users to void a Case and nullify previous transmissions.
See Suppress, Nullify, or Amend a Safety Report for more information.
