Leave to appeal June 1, 2019
 In PPK Willoughby Pty Ltd v Baird  NSWCA 48, this Court made reference to the proper approach of an intermediate appellate court to applications for leave to appeal from interlocutory decisions involving the exercise of discretion on questions of practice and procedure. The Court observed (at ) that discretionary decisions “engage the strictures against over-ready appellate interference and the correlative need for ‘added restraint’ associated with House v The King (1936) 55 CLR 499 with the consequence that a ‘heavy burden’ lies on an applicant seeking leave to appeal from a discretionary judgment on a question of practice or procedure” (citations omitted).
 The Court in that case also noted (at ) the well-established grounds which generally must be satisfied before leave to appeal to this Court is granted, namely that:
“Leave applications in this Court attract a general obligation on the applicant for leave to establish that there is an issue of principle, a question of public importance or a reasonably clear injustice going beyond something that is merely arguable: JaycarPty Ltd v Lombardo  NSWCA 284 at ; BEFinancial PtyLtd v Das  NSWCA 164 at -; AgeCoLtd v Liu (2013) 82 NSWLR 268;  NSWCA 26 at ; Secretary, Department of Family and Community Services v Smith (2017) 95 NSWLR 597;  NSWCA 206 at .”
