Leave to appeal December 15, 2015
45 In determining whether leave to appeal should be granted, however, something more must be demonstrated than that the decision was arguably wrong. What is ordinarily required to be demonstrated is that the matter involves a question of principle or of public importance or an injustice which is reasonably clear in the sense of going beyond what is merely arguable. (See Clarke v State of New South Wales  NSWCA 27; Carolan v AMF Bowling Pty Ltd t/as Bennetts Green Bowl  NSWCA 69; Jaycar Pty Limited v Lombardo  NSWCA 284; Be Financial Pty Ltd as Trustee for Be Financial Operations Trust v Das  NSWCA 164.) Where a disproportionate amount of time and cost will be involved, that is a factor tending against the grant of leave to appeal, particularly having regard to the case management principles enshrined in the Civil Procedure Act 2005 (NSW).
