6 Should there not be a contract between the plaintiff and the first defendant, and should the plaintiff be unable to accept the first defendant's tender, it appeared then that it was possible, although not inevitable, that the plaintiff might accept the lowest tender, that of BCG Construction. That entity, then using the name Home Style Pty Ltd ("Home Style"), applied to be joined as a party to the plaintiff's application. Master Sanderson took the view that BCG Construction or Home Style Pty Ltd had not a sufficient interest in the question of whether a contract existed between the plaintiff and the first defendant to be joined, but might well have an interest in the question of whether, if there were no contract, the first defendant's tender was one which it was open to the plaintiff to accept. He therefore rejected the application and referred for determination, in effect as preliminary issues, those issues set out at par 2.2 and par 2.3 of the originating summons.
