It's in relation to authority as to what had to be - the rules related to authority are not negotiable for the operative, particularly in relation to the identity of the target and other important aspects.  It may be that there is some merit in "go and kill Omar" and the gun jams and you have a knife and you then stab the person.  I don't know that that would be a breach of the authority but what Van Zyl said, "why didn't you kill the woman as well?", would it be completely beyond the authority?  So that as to whether, certainly in relation to Webb denying that there was authority has very serious consequences in relation to Verster.  We will deal with the bona fide belief of those under Verster and what the effect of it is going to be.
