Strict rules of evidence as per the Indian Evidence Act is not applicable in any proceedings before an Administrative Tribunal but only substantial rules of evidence i.e., the Principles of Natural Justice are only applicable. Sorry, I am not able to make out anything from your cryptic post about the evidence of employment of a person in a case against perjury before a criminal court in order to stop interim maintenance. Better you present the complete facts leading to your present question, if you are willing.
