ATS Infrastructure Defaulting in Buyback Agreement

We had invested with ATS infrastructure under their guaranteed buyback scheme in their property ATS Tourmaline, sector 108 in the year 2014. The terms of the scheme were as follows: 1. ATS guaranteed Purchaser/Investor to buy back the apartment at a premium after expiry of 3 years from the date of booking. 2. ATS agreed to pay 18% per annum interest for the period of delay on the total repurchase price payable to the Purchase/Investor. 3. ATS was liable to pay to the Bank all instalments, Pre possession EMI, interest to the bank directly and keep the Purchaser/Investor fully indemnified in this regard. 4. A Memorandum of Understanding (MOU) was duly signed between ATS and Investors for the scheme and a Tripartite Agreement was signed between the Bank (loan provider), ATS and Investors. As per the agreement, we had initiated the buyback agreement in the year 2017, and ATS had accepted to process the buyback. It has been 2 years since then and there has been no recourse. They are openly accepting the fact that they have defaulted. A case was filed with NCLT and an IRP was appointed but ATS got a stay from Supreme court on the same till July. In the meantime, they have not made any attempt to settle but are instead treating the affected buyer as defaulter. Also, the bank is constantly pressurising to pay the EMIs . What should be our next course of Action in this?
