Global permissions can also be revoked. Both Jira System Administrators and Jira Administrators can revoke global permissions, but Jira Administrators cannot revoke the Jira System Administrators global permission.

Perform the following steps to delete a global permission from a group:

1. Browse to the Global Permissions page
2. Click on the Delete link for the group you wish to remove from the global permission from
3. Click on the Delete button to revoke the global permission for the group

Jira has built-in validation rules to prevent you from accidentally locking yourself out by mistakenly removing the wrong permissions. For example, Jira will not let you delete the last group from Jira System Administrators global permissions, as doing so effectively prevent you from adding yourself back (since only Jira System Administrators can assign/revoke global permissions).
