When determining whether to grant leave to execute pending appeal, the court must exercise its discretion by determining what is just and equitable in all circumstances, having regard to: (1) the potentiality of irreparable harm to the appellant if leave is granted; (2) the potentiality of irreparable harm to the respondent if leave is refused; (3) the prospects of success on appeal, including whether the appeal is frivolous or vexatious; and (4) where both parties may suffer irreparable harm, the balance of hardship or convenience. Where a necessary party (such as a relevant Minister in a mining dispute) is absent from proceedings, this may tip the balance against granting leave to execute pending appeal, even if the absence was not fatal to the original application.
