Unjust suspension from the service (government)

I am a government official and suspended by my appointing authority for the work which is my job (example an accountant will maintain accounts and how can he be suspended for doing his job ? ). I am an IT manager and manage IT system of the organization. I received show cause that how do you have access to organizations database, or system admin privileges (which is in any case my job profile , how can i manage the system without having the admin rights on it. There is nothing wrongful done by getting these privileges. the question was not about what wrong is done rather it was like why do you have this privilege ? and in my reply I said sir in my appointment letter my duty and responsibility is to manage the database, system administration etc and without this privilege one can not manage the system, and after getting this reply he suspended me), which is something suspending me for doing my job. What can be done ? Can i file a case of defamation ? Am i entitled for compensation ? The current status is - charge sheet handed over , the IO has submitted his report giving me the clean chit some 2 months and 12 days ago. The Appointing authority is doing nothing on it
