I filed a recovery suit against a firm of Gurgaon,which was later on decreed on 5-7-2010 exparte as defendant didnot appear.Now my execution is pending whereas defendant now sent me a demand notice through email alleging that rs 50000/- are outstanding against me,it is important to mention here that for which transaction JD/defendent is claiming Rs. 50000/-,for the same transaction court has passed decree in my favour,i want to know is second suit is maintainable for same transaction/matter which has already decided ,secondly kindly tell me limitation for appeal for set asiding ex party decree.Thanx
