CHAIRPERSON
Sorry, Professor de Koker, we have a procedure you know in these proceedings, we don't just conduct hearings at random on an ad-hoc basis.  You can't just in the middle of the evidence, while you are cross-examining the witness just stop leading evidence and just start arguing certain aspects of the case in the middle of a hearing.
	We really find this to be causing us great difficulty.  If you have got points to argue, to raise and even you feel you want to criticise some the reports and the like, do that at the right stage.  We're busy talking about certain things which are matters of argument and the witness is in the meantime sitting in the witness box.  The witness is there for you to put questions to him - we lead evidence, finish the evidence and then argue the case later.
