8. Memorandum when evidence not taken down by Judge.
Where the evidence is not taken down in writing by the Judge, 2[or from his dictation in the open Court, or recorded mechanically in his presence,] he shall be bound, as the examination of each witness proceeds, to make a memorandum of the substance of what each witness deposes, and such memorandum shall be written and signed by the Judge and shall form part of the record.
Query : what does the above matter what to say ? because as per the reading it seems that when any witness gives the oral evidence in the open court the judge has to takedown the every evidence which the witness gives in oral i think the meaning but confused so pls clarify me ?
So what does grounds of appeal & memorandum of appeal means in simple wrods.
