Section 83 of the Evidence Act prescribed that an affidavit shall not be admitted which is proved to have been sworn before a person on whose behalf the same is offered or before his legal practitioner or a clerk of the legal practitioner. The import of this provision is that affidavits cannot be sworn before certain persons. Therefore the person duly authorised as commissioner of oath that signed the deponents’ affidavit must state his name. The information on name is verifiable.
