It is not possible to fully comprehend your question. I am replying to your question to the extent I could understand. Further please note that it is not possible for me to reply on the details facts of the case without having gone through the detailed facts.
It is not mandatory to file a cheque bounce case both under Section 138 of Negotiable Instruments Act and Section 420 of IPC. It depends on facts of the case concerned. But, generally, a cheque bounce case is filed only under Section 138 of the N.I. Act.
I cannot comment on whether this is the reason for dismissal of the case. For this, you have to read the judgment as to why it was dismissed. Consult your lawyer if you cannot draw the conclusions from the judgment.
No, if the original case was under Section 138 N.I. Act only, then it may not be possible to include Section 420 IPC while filing appeal.
Appeal has to be filed in the District (Sessions) Court.
I cannot comment on whether the appeal would be favourable to you. It all depends on detailed facts of the case and various other factors.
