Evidence of child of tender years 133a. Where, in any proceedings against any person for any offence, any child of tender years called as a witness does not in the opinion of the court understand the nature of an oath, his evidence may be received, though not given upon oath, if, in the opinion of the court, he is possessed of sufficient intelligence to justify the reception of the evidence, and understands the duty of speaking the truth; and his evidence, though not given on oath, but otherwise taken and reduced into writing in accordance with section 269 of the Criminal Procedure Code shall be deemed to be a deposition within the meaning of that section:

“evidence” includes— (a) all statements which the court permits or requires to be made before it by witnesses in relation to matters of fact under inquiry: such statements are called oral evidence; (b) all documents produced for the inspection of the court: such documents are called documentary evidence;
Provided that, where evidence admitted by virtue of this section is given on behalf of the prosecution, the accused shall not be liable to be convicted of the offence unless that evidence is corroborated by some other material evidence in support thereof implicating him.
