This discussion clarifies the process of adding new grounds of appeal, particularly when crucial documentary evidence was not presented in the lower court. Generally, appellate courts are reluctant to admit fresh evidence not considered during the trial. However, if the evidence proves the lower court's judgment is erroneous and was available but not considered, amending the memorandum of appeal might be possible. It's strongly advised to consult a local lawyer for specific guidance, as appellate courts typically review the trial court's proceedings and pleadings.
