Mismanagement of exam center during sbi po exam.

In response to your query

After reading your facts I understood that yours s a case of "Personal injury". It is a type of tort lawsuit in which the person suing has suffered physical, emotional or financial harm due to the actions of the person being sued.

Negligence is the most common cause of personal injury. Types of personal injury/ negligence- include gross negligence, reckless conduct, intentional misconduct and, in rare cases, strict liability.

Every personal injury claim has two basic issues: liability and financial compensation. The financial costs a plaintiff can recover are known as "damages," which typically include the injured person's medical bills, pain and suffering, and diminished quality of life.

So because you have suffered emotionally as you couldn't concentrate on your examination due invigilator's mistake therefore you can sue him for personal injury.
