What are the complaints against you that have been given as a retaliation to your complaint against the principal.?

If you have received a show cause notice in writing then you give a reply suitably mentioning that this notice is nothing but a vendetta due to yor complaint against the principal

Since your career is at stake you may have to take a wise decision either to withdraw your complaint or take up the matter legally.

If you are taking up legally then you may have to gather substantial evidence against the principal for all his acts of corruption.

The CBSE authorities may be in hand and glove with the principal or may be they do not want the reputation of the school to get spoiled or may be they also get their share out of such corrupt acts.

If you want yo can escalate the matter through ministry of education or department of education through its secretary and find a solution for this, but you must be prepared for a big legal battle against the giant machinery  which no doubt is corruptive and may be able to corrupt the authorities concerned. 

Move a representation with the concerned competent authority in the present matter, apprising the Authority of everything that has transpired till date. In your representation, you must explain in detail as to how the Principal is abusing his dominant position and taking recourse to corrupt practises.  Also specify as to how he is bent upon to harass you, just because you objected to his corrupt practices.

If no action is taken upon your representation, you may approach the High Court in a writ petition.
