Civil Case From Employer Under Law 1908 Section 9

First let me brief my case. I have been working on an organization for 2.5 years whose main office is in Gujarat and I am working in haryana in a branch office. 1.5 year before they were going to close their office in haryana and so they didn't pay my salary for 5-6 months and terminate me. On this I have put up my case on labor court just after 8-10 months. Now when my case summons reached to Gujarat office, the gujarat owner put up a case against me in civil court under 1908 section 9 stating that I didn't worked for all those time, due to which he loses some business which gives him a loss of around 30 lac. For this he registered a civil case in Gujarat court. Now my questions are: 1. Can he put up a civil case where I already puts up a case against him before his case. 2. If we get any summon related to Gujarat case then can we reply them through post/ email as we cannot travel to Gujarat every time. 3. Can an employer puts a civil case on his employee even after 10 months of termination. 4. Do we have any option to dispose his case or put up a hold on his case till my case gets over.
