(2) If it appears, or it is proved to the satisfaction of the Court, that the appellant has not complied with the requirements of this Sub-Part, with respect to the giving or service of notice of appeal or grounds of appeal or with the requirements of section 733, the Court shall dismiss the appeal and affirm the decision, with or without costs against the appellant, as it may think fit unless, on good and sufficient cause being shown, the Court considers that it would be most unjust in the circumstances to do so, in which case it may hear the appeal on such terms and conditions as it may consider proper or make any other order as it thinks fit.
