You are in dilemma only because you might not be aware of the process of law and you are not consulting with a good lawyer.
First thing, engage a lawyer. Best choice would be the one who won the case for your earlier. As he knows all the facts and seems intelligent enough to convince the lawyer, he would be probably pull you out of trouble again.
Now coming to your questions, whenever a court decides any case, the aggreived has a right to appeal to a higher court. Even in case of verdict from Supreme Court, you can again appeal in SC before a larger bench. In your case, you need not worry at all. It was the fault of Police which did not served any notices and your dates went in vain.
Now first thing to know is that if the appeal was filed within the prescribed limitation period of 6months. If not, then you can file an application before the court trying the appeal to dismiss the case on the grounds of limitation. But if the case was filed within 6months or if the court has already condoned the delay, then you will have to face and contest the appeal.
The primary reason for consideration of any court's order is if in the order the judge failed to note any important fact or made an error of law. Otherwise, a general appeal shall be dismissed within a year after institution.
If the appellant is able to convince the higher court and you loose this appeal, then you will be given approx one week to get your bail from Higher Court and in my view you all would get the bail easily. Once you are convicted, you would be ordered to surrender unless you have not taken bail from a higher court.
Just have faith in god and our courts, if you are true, nothing can cause any problem to you. All the best
