Withrawl of degree by institute

No degree can be withdrawn like that. Take a reason in wrting and take up the matter with UGC.

The degree once granted cannot be easily cancelled by any body. It should be done only by that  body   which has issued it and such strict action can only be taken affording an opportunity of hearing followed by passing a well reasoned order or speaking order mentioning all circumstances which lead to the decision. 

The matter doesnot seems to be common one as a inquiry was conducted by ministery as per your version agisnt such an reputed institution . It implies that its not only about your complaint. The issue seems to much more important as been projected by you. 

before taking any action , you must procure all the relevent information about the agenda of inquiry done and must have all necessary documents ready for filing a writ petition in HC concnered. You may obtain a relevent inforamation under Right to Information Act.

Finally consult a Expert /Advocate and proceed further.
