Upon the written pleadings follows the oral discussion in Court; it consists of the oral development of the pleas of the parties (article 63, last paragraph). The discussions are under the direction of the president of the tribunal, and are public only if it be so decided by the tribunal with the consent of the parties. Minutes with regard to the discussion are to be drawn up by secretaries appointed by the president, and only these official minutes, which are signed by the president and one of the secretaries, are authentic (article 66). During the discussion in Court the agents and counsel of the parties are authorised to present to the tribunal orally all the arguments they may think expedient in support of their case. They are likewise authorised to raise objections and to make incidental motions, but the decisions of the tribunal on these objections and motions are final and cannot form the subject of any further discussion.
