2 The parties entered into a written contract for the sale and purchase of the property in August 1999. The plaintiffs commenced this action on 21 August 2000. Initially they sought specific performance of the contract. By their statement of claim, which was filed with the writ, they also sought damages "in lieu of or in addition to specific performance". The defendant filed a defence to that statement of claim on 27 September 2000. However the plaintiffs had re-sold the property by a contract dated 4 September 2000. Apparently they had changed their minds about seeking specific performance by then at the latest. Thereafter, this litigation became surprisingly complex. The defendant made a number of interlocutory applications. He lodged a caveat in respect of the property, and the plaintiffs successfully instituted separate proceedings for its removal. A number of orders were made. The defendant was aggrieved by them, and instituted three Full Court appeals. He also commenced proceedings in the Federal Court against the present plaintiffs, their agent, and their original solicitor. A lot happened in the various proceedings, but for a long time nothing was done to amend the statement of claim in this action in consequence of the re-sale of the property. That was eventually done, at my instigation, on 5 July 2002. The defendant needed to file an amended defence, but never did so. I conducted a series of directions hearings over the following months. The defendant ceased to attend them, but continued to receive transcripts of what was said at them, and to submit documents to the Court. After my first deadline for the filing and service of an amended defence had passed, I ordered that it be filed on or before 2 September 2002, and made a self-executing order for the action to be dismissed if that was not done. Subsequently, information came to my attention suggesting that the defendant might be suffering from some form of psychiatric disorder. I directed that judgment was not to be entered against him until an order or direction to the contrary was given. Eventually I decided that, because of the possibility that the defendant was temporarily unfit to participate in court proceedings, the most just course was to order that the action be tried on affidavit, without pleadings, and to direct that it be listed for trial. Such a course gave the defendant an opportunity to participate in the trial, either personally or with legal representation. Such a course also made it possible, if he did not appear at the trial, for him to apply for a new trial under the Supreme Court Rules 2000, r563. Thus, if illness had prevented him from appearing at the trial, and the plaintiffs had succeeded, and he had applied for a new trial on recovering from his illness, a judge could have ordered a new trial if that was considered just. However, by the time the trial commenced, the defendant was apparently well enough to participate in court proceedings. I did not attempt to compel him to formulate his defences to the action in an amended pleading. I doubt that he would have been able to do so adequately. Thus, the trial proceeded on affidavits and without pleadings.
