(1) If a proceeding or defence, or any particular claim, cause of action or ground of defence ("claim") is hopeless, untenable, bound to fail, or could not possibly succeed, then it ought be summarily dismissed. In other words, a claim which ought be dismissed under the old test will be dismissed under s 63.
(2) Section 63, however, is less stringent. It does not direct an inquiry into whether a certain and concluded determination could be made that the proceeding, or a claim, would necessarily fail. What is required is a practical judgment by the court as to whether a claim has more than a "fanciful" prospect of success.
(3) The court's discretion whether to exercise the power of summary dismissal is very wide. Section 64 of the Act expresses that the power is based in a consideration of the interests of justice. The Act provides direction in Part 2.1. The discretion is to be exercised to facilitate the just, efficient, timely and cost effective resolution of the real issues in dispute between the parties. The court's powers in furthering the overarching purpose are facilitated by having regard to the objects and matters set out in s 9 of the Act.
(4) The court may be satisfied, on an interlocutory application, that there is no real prospect of success in a civil proceeding but nevertheless consider the dispute to be of such a nature that only a full hearing on the merits is appropriate. Whether a full hearing on the merits is appropriate is a relevant discretionary consideration in the circumstances of each proceeding.
(5) The power to order summary dismissal is to be exercised with great care, as a trial upon evidence of issues raised is the well-settled approach to the determination of litigation. When proceeding on a summary application to assess the prospect of success, a judge ought to feel confident that an assessment can properly be made of whether the overarching purpose is facilitated on dismissal of the impugned claims.
(6) That argument directed to the issues relevant on the application, perhaps even extensive submissions, may be necessary to demonstrate that the case of the plaintiff has no real prospect of success is not ordinarily a relevant consideration.
