[19] The defendants do not point to any prejudice flowing from delay other than the type of prejudice identified by McHugh J in Brisbane South Regional Health Authority v Taylor.[4] Such prejudice, of course, as His Honour points out, can be both real and substantial. I do not consider however that it should prove fatal to the application. As the plaintiff's counsel points out the plaintiff could, if the application were to be rejected, commence separate proceedings and seek to have them heard with the existing proceedings. Moreover, the defendants are all members of the same group of companies with, it would seem, a common interest in the outcome of the proceeding. There is also substance in the point that the fifth defendant has known of and had an involvement in matters subject of the proceedings for a considerable length of time.
