The formal offer of documentary or object evidence shall be made upon the termination of the testimony of a party’s last witness. This obviously means that this is done when a party rests its case, and not every time the testimony of each witness is terminated.
The formal offer is made orally in open court, which shows an obvious intent to do away with the option of filing a written formal offer of evidence allowed under existing rules. A party shall immediately make an oral offer of evidence of his documentary or object exhibits, piece by piece, in their chronological order, stating the purpose or purposes for which he offers the particular exhibit.
After each piece of exhibit is offered, the adverse party shall state the legal ground for his objection, if any, to its admission, and the court shall immediately make its ruling respecting that exhibit.
Since the documentary or object exhibits form part of the judicial affidavits that describe and authenticate them, it is sufficient that such exhibits are simply cited by their markings during the offer of evidence, the objections, and the rulings, dispensing with the description of each exhibit.
