Can victim become a party in Criminal Government appeal

Dear Sir,
Since already appeal is preferred as such you can approach the High Court and assist the Government pleader who is your pleader appointed on behalf of Government to expedite the matter. Otherwise seek appointment of your own advocate along with Government Advocate under following provision of law.
==================================================================================
PERMISSION TO SEEK ENGAGEMENT OF PRIVATE ADVOCATE IN CRIMINAL CASE ALONG WITH PROSECUTOR
Section 302 of the Cr.P.C.
(The Code of Criminal Procedure, 1973) and the two Judgments of the Hon'ble Supreme Court of India i.e. M/s. J.K. International vs. State, Govt of NCT of Delhi and Ors., and Dhariwal Industries Ltd. vs. Kishore Wadhwani and Ors, are the answer to the proposition that in the case of Magistrate Trial, a Complainant or any other person can, in addition to the Public Prosecutor, assist the Court and participate in the conduct of the Trial. The mandate of the Hon'ble Supreme Court of India in the above mentioned 2 cases is also the law of the land and binding on all Courts.

I could have explained more if background is known to me. I am at your service if you visit my office.
