On an application for leave to appeal, the Court is required to take into account the following considerations:
(a) The power to order an amendment to a pleading is discretionary and is therefore subject to the limitations identified in House v The King.[2]
(b) The decision of the trial judge was interlocutory in character. In Livingspring Pty Ltd v Kliger Partners,[3] this Court recognised the legislative policy in respect of the hearing of appeals against interlocutory orders and endorsed the statement of the Full Court in Perry v Smith,[4] that 'the object [of cutting down the number of interlocutory appeals] which Parliament had should be recognised by
this Court in a liberal manner, and not begrudgingly'.[5] As a consequence, appeals from interlocutory orders should not be permitted except in special circumstances.[6]
(c) The exercise of the discretion to allow an amendment does not determine substantive rights. It is a matter of practice and procedure. Accordingly, an appellate court should exercise particular caution in considering an application for a grant of leave to appeal decisions of that kind.[7] In Livingspring's case,[8] the Court said that we should be guided by the following statement of Sir Frederick Jordan in Re Will of Gilbert:
If a tight rein were not kept upon interference with the orders of Judges of first instance, the result would be disastrous to the proper administration of justice. The disposal of cases could be delayed interminably, and costs heaped up indefinitely, if a litigant with a long purse or a litigious disposition could, at will, in effect transfer all exercises of discretion in interlocutory applications from a Judge in Chambers to a Court of Appeal.[9]
Accordingly, leave to appeal should only be granted where there is sufficient doubt attending the decision below and substantial injustice would be done were the decision to stand.[10] These are stringent requirements.[11]
