a person who is required to answer a charge must know not only the accusation but also the testimony by which the accusation is supported.

"In Meenglas Tea Estate v. The workmen., AIR 1963 SC 1719, the Supreme Court observed "It is an elementary principle that a person who is required to answer a charge must know not only the accusation but also the testimony by which the accusation is supported. He must be given a fair chance to hear the evidence in support of the charge and to put such relevant questions by way to cross-examination as he desires. Then he must be given a chance to rebut the evidence led against him. This is the barest requirement of an enquiry of this character and this requirement must be substantially fulfilled before the result of the enquiry can be accepted".
