Regarding SF5 Charge Sheet

Hi, I have a serious query related to my friends carrier I work in a couple government organization. I felt sick and was on leave from last 2 years. i stay far away from city. I applied private medical sick . Doctor who issued certificate is a government doctor running camp at some other place. as I stay far away from city I did not went to department hospital. all this 2 years I have been submitting sick certificates time to time. Never there is any delay. During this period my close relatives approached member of parliament of my constituency with medical documents and asked if he can help in any way to get transferred to my native place. honorable MP gave a letter which was forwarded to my office administration by their office. now my office administration has issued standard form 5 charge sheet . they want to initiate action on me.  could you please let me know how to face it ? what can be the consequences. some people are telling that when employee has been on sick leave administration has no right to issue charge sheet .
