The binding legal principles established are: (1) Urgency is determined by when the need to act arises, not by when proceedings are initially instituted - where a party becomes aware of a default judgment and acts promptly to seek rescission and stay of execution, the matter is urgent notwithstanding earlier procedural steps; (2) An honest mistake by legal counsel in confusing case numbers does not constitute deliberate or careless abstention that defeats urgency; (3) Courts have discretion to condone procedural irregularities including pagination errors where the correct forms were used and no prejudice results; (4) For purposes of granting a stay of execution pending rescission, the applicant must demonstrate prospects of success in the rescission application; (5) Under section 105 of the Customs and Excise (General) Regulations, SI 154 of 2001, immigration stamps in a passport are the primary evidence for determining whether a person has resided outside Zimbabwe for the requisite period for an immigrant's rebate, and where a passport is altered or tampered with, it ceases to be valid documentary proof regardless of alternative evidence presented.
