reasonable level of certainty needs to be convicted

Reasonable level of certainty needs to be convicted 

case: Rang Bahadur Singh V. State of U.P. 

“The time-tested rule is that acquittal of a guilty person should be preferred to conviction of an innocent person. Unless the prosecution establishes the guilt of the accused beyond reasonable doubt a conviction cannot be passed on the accused. A criminal court cannot afford to deprive liberty of the appellants, lifelong liberty, without having at least a reasonable level of certainty that the appellants were the real culprits.”
