Learned counsel for the appellants contends that a preliminary issue was raised by the appellants before the Tribunal below regarding substitution of Kotak Mahindra Bank being valid or not relying upon a judgment dated 25.05.2009 passed by the Hon’ble High Court of Lucknow Bench in writ petition no. 11080(MB)/2008 filed by some other party, wherein the Hon’ble High Court has set aside the assignment deed, on the basis of which Kotak Mahindra Bank got itself substituted and the appellants also intended to file some application in this regard, but the Tribunal below did not consider the request of the appellant and declined to decide any issue as preliminary issue and vide impugned order dated 21.09.2016 fixed the case for hearing on 24.10.2016. Hence, the present appeal has been filed by the appellants praying that the impugned order dated 21.09.2016 may be set aside and the issue regarding substitution of Kotak Mahindra Bank be decided as preliminary issue.
