Dear Sogemar,
" Examination-in-Chief " which is also called as " Direct Examination " is the starting point in any litigation. It has been defined u/s 137 of the Indian Evidence Act,1872.
The Examination-in-Chief of a witness by a party who calls him shall be his Examination-in-Chief. It is the first oral evidence after the witness has been sworn in before the adjudicating forum.
It is the province of the party by whom the witness is called to examine for the purpose of eliciting from the witness all the material facts within his knowledge which tend to prove the party's case.
With reference to the case in the Labor Court, the claimant has to state orally what he has already mentioned in the claim statement putting forth all the facts cogently leading to the claim. If the claim is pertaining to his dismissal or discharge or retrenchment from service, he has to state the position held by him under the respondent, the period of employment right from his appointment, the salary last drawn,the circumstances leading to the cause of action and the remedy prayed for. Along the course of his evidence, he should mark the documents if any as his exhibits.
