In Qlik Sense 1.0 it was possible for the Root Admin to make change to the Root Admin rule and as a result lock himself out. That kinda defies the whole idea behind a root admin; "he/she with all access". We got a lot of complains of people accidentally doing this, locking themselves out of the QMC and ending up doing a shift-delete and a full reinstall. So this was fixed in QS 1.1.
I am not a legal expert, but I would make sure the root admin has signed all related privacy statements and contracts.
