Yes but this doesn't obey immunity, it can counter it. You see, there was a server (here is admin manual)
http://ownageclan.com/adminmanual1.php that I played once, and it had a RCON Kick command, so you can kick other admins with immunity if they were abusing their powers. I may wanna add a ban command too
On the link, scroll down on that page and you will see the command...
