Effect of admission

DRC 15(1) order passed in favur of tenant. landlord files a new case challenging the jurisdiction of DRCA and admitting that DRCA doesn't applies to the area so the previous order/decree u/s.15(1) are a nullity and the tenant also doesn't objects to it. So now does this absolves the tenant to stop paying the rent?? Thanks in advance for the time taken to provide valuable opinions.
