Once the judgement is passed, a debtor may want to appeal to Appellate tribunal. 
But here there is problem.
At the time of filing appeal, debtor has to deposit 50% of amount. 
In Special cases, Tribunal may reduce such deposit to 25%.
But in no case, it can totally wave deposit. Appeal is not maintainable unless deposit is made.
For more reference, please check judgement of Supreme Court dated 18/3/2011 in case of N C G versus UCO Bank.
