Canon 401 §1 of the
1983 Code of Canon Law states that archdiocesan/diocesan bishops (including cardinals) are requested to submit their resignation to the pope on reaching the age of 75 years. Some do so earlier with a view to having the resignation take effect immediately on reaching 75. Bishops should also offer their resignation if ill-health or other grave problems render them unsuited for fulfilling their office. The letter of resignation goes first to the
apostolic nuncio or
apostolic delegate, the pope's representative in the country or region. He forwards it to whichever department of the
Holy See has particular responsibility for the selection of bishops for the country in question: the
Dicastery for Evangelization in the case of mission countries, the
Dicastery for the Eastern Churches in the case of even
Latin bishops in certain Middle Eastern countries and Greece, the
Secretariat of State if the country's government has been given the right to present objections of "a general political nature" (not of a party-political kind) or is involved in some other way, but generally the
Dicastery for Bishops. The congregation presents the bishop's offer of resignation to the pope, who has a range of options from rejecting the offer of resignation to accepting it with immediate effect. In the case of diocesan bishops who have reached 75 years of age, the usual decision is to accept the resignation but with effect only from the date of publication of the appointment of a successor, a decision known as acceptance
nunc pro tunc (now for then). If the resignation is accepted with immediate effect, the
episcopal see becomes vacant on publication of the pope's decision. Vacancy of a see may also occur because of a bishop's transfer to another see or position, or because of his death. In the case of a
nunc pro tunc acceptance, the see does not become vacant immediately, but the process that leads to the appointment of a successor begins without delay. One important element in selecting a bishop is the list of priests, of both the
diocesan and the
religious clergy, that the bishops of the ecclesiastical province or the whole
episcopal conference judge to be suitable generically (without reference to any particular see) for appointment as bishops. They are required to draw up this list at least once every three years, so that it is always recent. When it comes to a concrete appointment for a particular see, the papal representative (apostolic nuncio or delegate) asks either the outgoing bishop, or in case of a
sede vacante, the
vicar general or
diocesan administrator, to draw up a report on its situation and the needs. That person will be the bishop who has presented his resignation or, if the see is vacant, the diocesan administrator or
apostolic administrator. The papal representative is also obliged to consult the
metropolitan archbishop and the other bishops of the province, the president of the bishops conference, and at least some members of the
college of consultors and the
cathedral chapter. He may also consult others, whether clergy, diocesan or religious, and "lay persons of outstanding wisdom". Canon law insists on enabling those consulted to provide information and express their views confidentially, requiring that they be consulted "individually and in secret". Accordingly, when the
Irish Times of 12 April 2007 published the text of the letter with which Archbishop
Giuseppe Lazzarotto,
Apostolic Nuncio to Ireland, consulted certain priests on the choice of their next bishop, he said, "All aspects relating to the process of episcopal appointments should be dealt with in the strictest confidentiality. I trust that you will understand that I cannot depart from this practice." The nuncio then decides on a short list, or
terna, of three candidates for further investigation and seeks precise information on each of them. Since if it were widely known that a priest who was not the one who was finally chosen for the post had been under consideration, people might think he had been excluded because of some fault found in him, the nuncio will ask those consulted about individual candidates to observe the strictest confidentiality on the fact of the consultation. He will then send to the Holy See a list of the (usually) three candidates that seem to be the most appropriate for consideration, together with all the information that has been gathered on them and accompanying the information with the conclusions that he himself draws from the evidence. The qualities that a candidate must have are listed in canon 378 §1. As well as being at least 35 years old and a priest for at least 5 years, he should be "outstanding in strong faith, good morals, piety, zeal for souls, wisdom, prudence and human virtues", and should possess the other qualities needed for fulfilling the office in question; and he should be well versed in sacred Scripture, theology and canon law and, preferably, hold a doctorate in one of these fields. Moreover, according to ancient tradition bishops are always to be celibate and exceptions are not granted (this is not generally an issue as Roman Catholics priests are required to be celibate but it happens in
personal ordinariates for former Anglicans: should a married priest be appointed an ordinary of an ordinariate he isn't consecrated bishop and rules the ordinariate as a priest). The
Dicasteries of the
Roman Curia responsible for the appointment (one of the four indicated above) studies the documentation provided by the nuncio, taking into consideration his opinion, but not necessarily accepting it. It might even reject all the candidates he has proposed and ask him to prepare another list, or it might ask him to provide more information on one or more of the individuals who have already been presented. When the congregation decides on which person should be appointed, the list and the related conclusions are presented to the pope, asking him to make the appointment. If he agrees, the papal act is communicated to the nuncio for him to obtain the consent of the individual to his appointment and to choose a date for its publication. The newly appointed bishop is obliged to get episcopal consecration within three months of the arrival of the
papal bull of his appointment, which is usually prepared at least a month after the publication. If the consecration takes place within the diocese, he takes charge immediately. If it occurs elsewhere, a separate act is required, after the consecration, for taking possession of his new post. Bringing the process to a conclusion requires much time, usually taking at least nine months, and it may on occasion take up to two years. The procedure described above is the normal one for the appointment of a diocesan bishop. In the case of an
auxiliary bishop, the diocesan bishop chooses the three priests to be presented for the appointment, but the nuncio still has the duty of gathering information and opinions on the candidates, and the congregation can either select one of them or ask for a different list of candidates to be presented. In some countries, the diocesan
chapter or some other body decides on the three names to send, through the nuncio, to the Holy See. With the names, the nuncio sends the information he has gathered on the candidates. If none of the three candidates is acceptable to the Holy See, the chapter is asked for another list. However, the Holy See can reject the list in its entirety and appoint someone not proposed by the chapter. In other cases the cathedral chapter chooses the bishop from among a list of three presented to them by the Holy See. The chapter participates in the election of bishops of 13 of the 27 German dioceses (
Aachen,
Cologne,
Essen,
Freiburg,
Fulda,
Hildesheim,
Limburg,
Mainz,
Münster,
Osnabrück,
Paderborn,
Rottenburg-Stuttgart,
Trier), 3 Swiss dioceses (
Basel,
Chur,
Sankt Gallen), and 1 Austrian (
Salzburg). For the
personal ordinariates established under the
apostolic constitution Anglicanorum Coetibus, out of respect for the synodal tradition of Anglicanism, the ordinary will be appointed by the Roman pontiff from a
terna of names presented by the governing council (CN Art. 4 § 1) In the past, privileges regarding the appointment of bishops were granted to kings and other civil authorities. In accordance with the decision of the
Second Vatican Council, the 1983 Code of Canon Law lays down that "for the future, no rights or privileges of election, appointment, presentation or designation of Bishops are conceded to civil authorities." In about a dozen countries, the civil government still has the right of consultation or even of presentation. ==Eastern Catholic Churches==
