Mutual consent divorce

The conviction will not be set aside just because you are going for mutual consent divorce.

You have to fight it in appeal and get it set aside and acquitted.

If this was before the disposal of the case by the trial court then at least you could have filed a quash petition. 

Who has proposed mutual consent? Is the other spice agreeing? What are the terms, if any?

The accused filed an appeal, which the court should set aside.  Mutual consent means is your wife agrees to it,  if so, on what terms and conditions.

Get the appeal case forwarded to Mediation Centre of the appellate court and get the terms endorsed in mutual consent divorce.

You should consult your lawyer who is well aware about facts of the case, an intelligent, able and competent person to advise you properly.
