No. If you look at the Guide to VMS System Security you will find (Figure
4-4) a flowchart. Even if an ACL explicitly denies access then it will
branch off to BB (UIC based checks). If the requester UIC is the owner UIC
then it checks the protection code for the object. If you read between the
lines of section 4.2.3 then it is clear that UIC based protection always
grants CONTROL access to the owner.
