Email overlooked - student debarred

A lawsuit based on negligence is a type of personal injury claim. When someone acts carelessly and injures another person, they are legally liable. As in this case, due to the coordinator's negligence in overlooking your mail and forwarding the list of debarred students without making the necessary changes at his end, your daughter suffered despite her appearing for the exams.
Typically, educational institutions are considerate of children's medical conditions. If the coordinator of exams overlooked the mail you sent regarding your daughter's permission to appear for the exam provided by the concerned professor, he is liable for negligence and can be held for trial in a civil court for the same. 
You must show a failure on the part of the coordinator/ educational institution to meet their reasonable obligation of care to prove that they are at fault. You would also be required to illustrate proof of negligence. In this case, it would be the mail sent by you and the approval of the concerned professor. 
Thus to answer your query specifically-  You can file a lawsuit on negligence against the coordinator/ educational institution in the civil court.
I hope this helps.

Thank you very much for your kind reply. It helps a lot and provides direction for me. I had approached the management and i think they must have realised their mistake and have assured me that they will remove her name from the debarred list.
