(3) The Court may, subject to such terms and conditions as it thinks fit, extend the time limits mentioned in sub-sections (1) and (2), if the appellant shows to the satisfaction of the Court that he has been unavoidably prevented from filing his notice of appeal or grounds of appeal, as the case may be, provided that on the hearing of any application for an extension of time under this subsection, the opposite party shall have an opportunity of being heard and, if the Court thinks fit, of adducing evidence against the granting of leave. appeal for
