9 I have indicated earlier in this decision the plaintiff filed its statement of claim on 11 March 2008 and the first defendant filed its original defence on 26 March 2008. Mr M W Schwikkard, a partner of the law firm, Jackson McDonald, deposed in an affidavit that on the basis of instructions received up until March 2008 and documents provided by the first defendant, he prepared a defence which he forwarded to the first defendant for comment on 20 March 2008. The first defendant made several minor changes but did not provide any instructions that the statement of claim had pleaded the incorrect contract. Mr Schwikkard deposed that the plaintiff made discovery on 22 May 2008 but inspection was delayed pending negotiations. Inspection occurred on 7 January 2009. Further supplementary discovery was made by the plaintiff on 20 February 2009, 20 April 2009, 12 May 2009 and 13 May 2009. From the discovered documents and from interviewing witnesses, Mr Schwikkard concluded that the relevant contract was not the BSD contract pleaded in the statement of claim but was the Head Contract as pleaded in the minute of the proposed amended defence.
