I think would think rather Mr Visser, that it is evidence but you have a right of cross-examination if you wish to challenge any - that this is evidence in chief so to speak.  If they wish to challenge you can then say we want to cross-examine those people.  If you don't want to - because it seems to me gentlemen that this is a largely academic discussion.  On the evidence - information available it appears quite clear this man was poisoned, how and in what manner, we don't know but the evidence really - none of these doctors seeks to point a finger at any particular person, they merely relate the symptoms they found at certain times and I don't think that they are really in dispute are they?
