ADV DE JAGER
Mr de Koker, we only accept sworn statements as evidence.  If all the parties accept this as the truth, you can submit these but it has no meaning if the person who made the affidavit is not available to be questioned by the other interested parties.  You can negotiate with the other parties, if you agree that these papers be handed in, then it can be done otherwise it's quite pointless unless they're all going to be prepared to stand and give evidence and cross-questioned.
