18 On the last possible day for compliance with the order dated 3 February 1999, Jeanette May Chesson swore an affidavit of discovery in respect of the first, sixth, and seventh named third defendants by counterclaim, they being, Callao Pty Ltd as trustee for the S J Chesson Family Trust, Austasia Real Estate Pty Ltd as trustee for the Dutco Superannuation Fund, and Austasia Real Estate Pty Ltd. Precisely three documents were discovered, two being certificates of incorporation in respect of Callao Pty Ltd and in respect of what is described as "Ducto", but is probably intended to be Dutco, and a certificate of registration on change of name. The only documents which Mrs Chesson deposed Callao and Austasia did have in their possession but do not now have in their possession, custody or power, were originals of letters written by Callao's and Austasia's solicitors to the plaintiffs' solicitors (presumably a reference to the plaintiffs by counterclaim) and the originals of pleadings and other documents filed in court by Callao's and Austasia's solicitors. There are in the affidavit the usual references to instructions; notes and memoranda prepared for solicitors in Pt II in the first Schedule to the list. Otherwise, Mrs Chesson deposed that neither Callao nor Austasia nor any other person on their behalf has now or ever have had in their possession, custody, or power any other document whatever relating to any matter in question in this action. For completeness, I note that Mrs Chesson's affidavit deposes that she is a director of each of the third defendants to which I have referred, and is authorised by them to make the affidavit.
