Challenging departmental penalty

Sir, I work in a psu and have been penalized by my department based on some assumption .Inquiry was held and article of charges remained not proved against me .However the disciplinary authority didn't accepted the inquiry findings and served disagreement memorandum and finally penalised me.I submitted my appeal to my appealate authority which was also rejected by him.The charges framed against me are against our manual..Now if I try to move to court for justice the empanel lawyer of my dept will definitely make plea that I have not exhausted all the channels of my dept and will ask to write to our CMD..The court has accepted such plea in past .Is there any legal remedy which will allow me to settle through court itself and stop from going to CMD.Already the disciplinary authority has penalized me and the appellate authority has rejected my plea and it took 4 years to complete this process. I want to settle my case through high court instead of CMD because it will impact my career.
