Interim Maintenance Appeal

Hi All, My wife has got interim maintenance order under DVC, Rs. 27000/- per month and order says interim maintenance is applicable till final DVC is adjudicated. I did not go for appeal on humanitarian ground believing she will withdraw the case and join me back with my daughter. However, she ditched me and filed criminal appeal for this interim order, asking 1 lakh per month for her and our daughter. I have been paying interim maintenance regularly, she is dragging original DVC case and after two years it is still in PW-3 cross state. There is no prima fascia evidence against me and my family that she has alleged in DVC. She has worked for 5 years before she filed the case, an MBA graduate and have completed B.Ed also, but after filling the case, she is presenting herself as a "bechari" women and says she can't work now and need money for her maintenance. I have filed for Divorce as well, but that will take longer time. My salary is 1.3 lakh and my mother is dependent on me, also I have been paying 32K home loan and many other expenses, including my medical expenses, hyper tension, heart related medicines that I got after this DVC case. 1. Do we have any judgment which says if DVC is running and adjudicated, appeal ti enhance interim maintenance should not be entertained by the higher court? 2. How do I fight this case? Please help! thanks Ravi
