Examinations

Students accused of cheating on college campuses should hire a student defense attorney – in particular, one who understands that a cheating case will look more like a computer crimes defense than a college code of conduct infraction.

• Read the accusations against you carefully — more than once — and talk to your parents or other guardians in your life who can give you good advice and possibly help you pay for an attorney. 
• Do not speak about the accusations against you to any other students on campus, even if they are your friends. 
• Do not try to defend yourself to the professor who’s accusing you — or anyone else on campus — before you’ve spoken to your attorney. 

How do you say the student was expelled on false /speculative cheating ? Can you prove your statement?

If so, submit your representation to institution..

In sensitive matters always trust a local advocate and step in for remedy as per his directions, if you are really innocent.

The authority is bound to hear the alleged wrong doer before taking any action which entails civil consequences.
