Bank Imposed Legal Charges And Forcing ToPay

Hi, I've taken a home loan from PSU bank for Amarpali Builder Flat. Amarpali did fraud with thousand of buyers and case is running in supreme court. I've book flat in July 2012, and bank disbursed 40% (12 Lac) of loan amount till 2014, and i was paying EMI from july 2012 till June 2017, and stop paying EMI from July 2017 (because there was no hope and development on project). Bank send me notice from "debt tribunal recovery" in Oct 2018 to pay the dues. I've paid 18-20 month EMI in 2-3 installment with interest from Jan - March 2019. Now Bank asking me to deposit 45K as lawyer fees, I am already in paid since not getting flat and paying EMI with no hope and now bank also pressurising me for 45K while i am paying EMi on time also. Now what to do and how to avoid this 45K
