tenant sents suit, claiming 5 Lakh, is it possible?

I had rented a shop for a sweet and snacks stall and entered into 11 months agreement. After 7 months I personally served 2 months notice for vacating 3 shops i owned for my own purpose of the premise for starting a business. This particular sweet and snacks shop tenant is not vacating, I had several meetings with him but he is still postponing with requesting 1 more month and this has now reach 5 months. I finally cut the power supply, he made a CSR police complaint, and after discussion, he confirmed to vacate in 1 month and gave a written statement in the police station hence i released electricity and also I served a legal notice to him to vacate by April 19th. He replied on 18th April with notice claiming he had losses of 5 lakh bec of vacating, he claims 5 lakhs. Finally 29th April he had sent suit & applied ad -interim. I had to rush on 30th April for appearing with a lawyer. What should I do further? this falls in munsiple court rural, ponneri, tiruvallur district, Tamilnadu.
