1. In appeals limited to questions of law by statute (such as section 92F(1) of the Labour Act), merely alleging an "error at law" or "misdirection at law" is insufficient to establish a valid ground of appeal - the ground must clearly disclose what legal question is to be determined. 2. A finding that delay in making an application is inordinate and the explanation for delay is unreasonable constitutes a factual finding, not a question of law, unless the finding is grossly unreasonable (i.e., a finding no reasonable court would make). 3. An appellate court will not interfere with a lower court's exercise of discretion in granting or refusing condonation except where: (a) the lower court acted upon a wrong principle; (b) it allowed extraneous or irrelevant matters to guide it; (c) it mistook the facts; or (d) it failed to take into account some relevant consideration (applying Barros v Chimphonda principles). 4. Condonation is an indulgence granted at the discretion of the court, not a right obtainable on request, and requires consideration of the length of delay, reasonableness of explanation, prospects of success, and need for finality in litigation.
