delay in disposal of appeal at high court

Sir My wife filed a case for maintenance under 125 of CrPC at family court alwar,on false claims/misrepresentation of facts.An appeal is pending at high court Jaipur for more than one year.Actually it is a case of money extortion by in -laws. A maintenance of 25000 out of 41000 has been awarded ignoring my liabilities/home loan instalments. How to get my appeal to be decided speedly at high court? Any direction from supreme court will be right in this regard?
