Whistle blow

The dismissal from service can be done only after proper departmental enquiry conducted 

Did the employer order for any enquiry into the irregularity?

No Whistle blowing doesn't fall under any sort of financial fraud or job related irregularity , it will fall under professional misconduct for which dismissal as punishment is against the Doctrine of Proportionality.

Whistle blowing is not an offence for which an employee may be suspended and dismissed as stated by you.

Whether there was a departmental inquiry conducted before passing the order of dismissal, if so, did the deliquent official defend properly ?

What are the facts of the case and your concern? 

Instead of posting an examination hall question paper, it would be appreciated if you may come out with your dispute /problem for consideration and obligation of experts on this platform.
