3. After the electors have taken this oath, they shall proceed to the election, and shall not depart from Frankfort until the majority have elected a king of the Romans and future emperor, to be ruler of the world and of the Christian people. If they have not come to a decision within thirty days from the day on which they took the above oath, after that they shall live upon bread and water and shall not leave the city until the election has been decided. 4. Such an election shall be as valid as if all the princes had agreed unanimously and without difference upon a candidate. If any one of the princes or his representatives has been hindered or delayed for a time, but arrives before the election is over, he shall be admitted and shall take part in the election at the stage which had been reached at the time of his arrival. According to the ancient and approved custom, the king of the Romans elect, immediately after his election and before he takes up any other business of the empire, shall confirm and approve by sealed letters for each and all of the electoral princes, ecclesiastical and secular, the privileges, charters, rights, liberties, concessions, ancient customs, and dignities, and whatever else the princes held and possessed from the empire at the time of the election; and he shall renew the confirmation and approval when he becomes emperor. The original confirmation shall be made by him as king, and the renewal as emperor. It is his duty to do this graciously and in good faith, and not to hinder the princes in the exercise of their rights. 5. In the case where three of the electors vote for a fourth electoral prince, his vote shall have the same value as that of the others to make a majority and decide the election. CHAPTER III.
