What if I got court notice of proclamation?

My father followed all bank guidelines and sanctioned poor farmers those loans. Total loan was of Rs 25 lakhs and now outstanding is around 10-12 lakhs. There was an inquiry set up by the bank. He was asked questions by senior authorities regarding this fraud and he answered all. We thought the matter was over as the bank lawyer told he will inform if anything happens further. But after my father got transferred, there was huge fight between the new manager and all customers. Fight was very serious and police was also involved. After 5 years, my father received a court notice of proclamation. This letter was dated in 2017 but he received it in 2023.
