SESSION 7 6 November 1432 [Interval for a papal election]

The most holy general synod of Basel, legitimately assembled in the holy Spirit, representing the universal church, for an everlasting record. Earlier this holy synod issued a decree about the election of a Roman pontiff if a vacancy of the apostolic see occurs during this sacred council. It is entitled, It pertains to the duty of providence . . . , and is to be found in full in the fourth session. However, a doubt about that decree has occurred to some, namely that the interval of ten days which the constitution of the council of Lyons fixed for the cardinals of the holy Roman church to enter the conclave, might elapse and be too restricted at least by the time that notification of the vacancy reaches this council. For, the interval would seems to be too rigid and too short for many of the cardinals who may be away in localities distant from this council. Moreover this holy synod wishes to eliminate all grounds for doubt and to provide carefully for what is conducive to the peace and unity of God's holy church, and with all modesty and due maturity to proceed with what is known in this matter, as in all things to promote the exaltation of the catholic faith and the general reformation and peace of the christian people, for which the council is legitimately assembled in the holy Spirit. It therefore decrees that in the case of a vacancy of the apostolic see in the lifetime of this present council, nothing shall be done for the election of a Roman pontiff before the expiry of sixty days from the day of the vacancy.
