The dumb witness is one who is unable to speak due to physical deformity. Section 119 applies only to those cases when the witness is deaf and mute or a person who has taken a religious van of silence. In case of such witness the evidence may be taken by means of written questions-answers techniques or by recording signs. The evidence given shall be deemed to be oral evidence. “The reception of the evidence of such person rests on the ground of expediency.”
The court while recording the evidence of dumb witness, must record both signs as well as the interpretations of the interpreter and then only it becomes admissible under the Indian Evidence Act.
