Mitis Iudex Dominus Iesus (2015)

Pope Francis’s apostolic letter motu proprio of 15 August 2015, reforming the canonical process for the declaration of marriage nullity. Preamble, eight fundamental criteria, and the key articles of the annexed Ratio procedendi — the rules every tribunal now applies. In force 8 December 2015.

What this document is. The 2015 reform that rewrote how every Latin-rite marriage tribunal runs a nullity case. Mitis Iudex — “The Gentle Judge” — replaced cann. 1671–1691 of the 1983 Code in their entirety and annexed twenty-one supplementary articles (the Ratio procedendi) that govern the day-to-day practice of the tribunal. Its companion document for the Eastern Catholic Churches, Mitis et misericors Iesus, makes parallel changes to the Codex Canonum Ecclesiarum Orientalium.

Why a petitioner reads it. Three reasons. First, the “new process” everyone refers to is this document. Second, the question of whether your case proceeds by the ordinary process or the briefer process before the bishop turns on the circumstances named in art. 14 §1 of the Ratio — that article is reproduced verbatim below. Third, the headline change — that an affirmative first-instance sentence is now executive after the appeal term lapses, with no automatic confirmation by a second instance — is the reason a 2026 case can reach its end in months rather than years.

The companion document is the 1983 Code itself, post-amendment. The replaced canon texts (cann. 1671, 1672, 1673, 1675, 1676, 1677, 1678, 1679, 1680, 1683, 1685, 1687, 1688, 1691) are walked verbatim with per-canon commentary in the CIC 1671–1707 library entry. This page reproduces the parts of Mitis Iudex that are not in the Code itself: the preamble, the eight fundamental criteria, and the Ratio procedendi.

Section I

The preamble — why Pope Francis reformed the process

Preamble — opening

The Gentle Judge, the salvation of souls, and the keys

The Gentle Judge, the Lord Jesus, the Shepherd of our Souls, entrusted to the Apostle Peter and to his Successors the power of the keys to carry out in the Church the work of justice and truth; this supreme and universal power of binding and loosing here on earth asserts, strengthens, and protects the power of Pastors of particular Churches, by virtue of which they have the sacred right and the duty before the Lord to enact judgment toward those entrusted to their care.

What this opening signals. Pope Francis frames the reform inside the salvation-of-souls principle: the canonical process exists not as an end in itself but as a service of the salus animarum, the supreme law of the Church (can. 1752). The bishop is named, in the first sentence, as the one who enacts judgment toward those entrusted to him — not the tribunal as an autonomous office.

What it means for you. The motu proprio's posture toward the petitioner is pastoral. The procedural changes that follow are oriented at reducing delay, expanding access, and placing the bishop closer to the case. Read the rest of the document with that lens in mind.

Preamble — the synodal mandate

The synod fathers and the call for a swifter process

Through the centuries, in acquiring a clearer awareness of the words of Christ, the Church has come to and has expounded more deeply the doctrine of the indissolubility of the sacred bond of marriage, has elaborated the system of nullities of matrimonial consent, and has more properly disciplined the judicial process in such a manner that ecclesiastical discipline may be more consistent with the truth of the faith she professes.

All this has been done with the supreme law of the salvation of souls always as a guide, given that the Church, as Blessed Paul VI wisely taught, is the divine plan of the Trinity, and so all of her institutions, even though always perfectible, must aim toward the goal of conveying divine grace and consistently, according to the gifts and the mission of each one, favoring the good of the faithful, in that this is the essential end of the Church.

Aware of all this, I decided to undertake the reform of the processes regarding the nullity of marriage, and I have to this end constituted a Group of persons preeminent for their juridical doctrine, their pastoral prudence, and their forensic experience who, under the guidance of the Most Excellent Dean of the Roman Rota, have sketched the project of reform…

The synodal context. The motu proprio was promulgated in August 2015, between the two assemblies of the Synod on the Family (October 2014 and October 2015). The synod fathers had repeatedly raised the cost (in time, in money, in pastoral burden) of the existing two-instance process — especially for petitioners in remote dioceses or in regions with very few qualified tribunal personnel. The reform was Pope Francis’s direct response to that synodal concern, drafted by a commission led by Msgr. Pio Vito Pinto, then Dean of the Roman Rota.

What did not change. The motu proprio is explicit, in the preamble and throughout: the substantive doctrine of marriage — its indissolubility, the canonical grounds of nullity, the requirement of moral certitude in the judge before a declaration of nullity is given — is not touched. What changed is procedural: how the tribunal does its work, not what the tribunal must find before it declares.

Section II

The eight fundamental criteria of the reform

Preamble — the criteria block

The eight criteria that organize every change

Pope Francis names, in the preamble, eight fundamental criteria that guided the work of the reform commission. They are the spine of the motu proprio: every change to the Code, and every article of the Ratio procedendi, can be referred to one of these eight. They are reproduced below, in order, with the Pope’s own framing followed by Companion commentary.

  1. A single executive sentence in favor of nullity

    Above all, it seemed that the double conforming decision in favor of the nullity of the marriage was no longer necessary in order for the parties to be admitted to new canonical marriages; it was instead sufficient that the moral certitude of the first judge be reached according to the law.

    The headline change. Before 2015, an affirmative sentence (a declaration of nullity) at the first-instance tribunal automatically went to a second-instance tribunal for confirmation; only after a “double conforming decision” was the petitioner free to marry again. The reform abolishes the automatic second-instance review. A single affirmative sentence is executive after the fifteen-day appeal window lapses (CIC can. 1679, can. 1630 §1). The right of appeal remains; the automatic re-review does not.

  2. A single judge under the responsibility of the bishop

    A single judge has been established, under the responsibility of the bishop, in the first instance. The bishop, in the exercise of his pastoral function with his proper judicial power, will assure that no laxity is permitted in this regard.

    The widening of the sole-judge faculty. A college of three judges remains the norm (CIC can. 1673 §3). But where a college cannot be constituted in the diocese or in a nearby tribunal, the bishop is to commit the case to a sole clerical judge, ordinarily with two lay assessors (CIC can. 1673 §4). The motu proprio reframed this as a normal exception, not an emergency one, especially for dioceses with limited tribunal personnel.

  3. The bishop himself is judge

    The bishop himself is judge. So that the teaching of the Second Vatican Council finally be brought into practice in an area of great importance, it has been decided to render evident the fact that the bishop himself, in his Church, of which he is constituted shepherd and head, is by that very fact the judge of those faithful entrusted to his care.

    The recovery of the bishop as judge. The Council taught (LG 27) that the bishop holds in his particular Church the threefold office of teaching, sanctifying, and governing — the governing office includes the judicial. Mitis Iudex makes this concrete by giving the bishop personal competence in the briefer process (CIC can. 1683, can. 1687) and by reaffirming his role as the first-instance judge by canonical right (can. 1673 §1).

  4. A briefer process

    It has been established, in fact, in addition to the documentary process, a briefer process — in addition to the current ordinary process — to be applied in those cases in which the alleged nullity of marriage is supported by particularly clear arguments.

    The processus brevior. A new procedural track, distinct from both the ordinary process and the documentary process. It is reserved to cases where (1) both parties petition or one petitions with the other’s consent, and (2) the nullity is supported by particularly clear arguments. The bishop himself is the judge. The instruction is compressed; the sentence comes from the bishop personally. Where the bishop cannot reach moral certitude in the briefer process, the case reverts to the ordinary process (CIC can. 1687 §4). The circumstances permitting use of the briefer process are enumerated at art. 14 §1 of the Ratio, below.

  5. The appeal to the Metropolitan See

    The appeal to the Metropolitan See has been restored, given that the function of headship of a Province, stable in the centuries, is a distinctive sign of the synodality in the Church.

    The route of appeal. Under the reform, an appeal against the sentence of a suffragan diocese normally goes to the tribunal of the Metropolitan see (the archdiocese of the province); an appeal from the Metropolitan’s own diocese goes to a tribunal stably designated by him; appeals from sentences of the briefer process go to the Metropolitan. The Roman Rota remains as the ordinary second-instance appellate tribunal for any case the parties wish to lodge there (CIC can. 1680, §1).

  6. The proper task of the Episcopal Conferences

    Episcopal Conferences should be inspired by the duty to share with the bishops the implementation of the reform, with respect for the right of bishops to set up tribunals in their dioceses. The reinstitution of the proximity between the judge and the faithful, in fact, will not have success if the stimulus does not come from the Conferences to the individual bishops, together with the necessary help to bring into practice the reform of the matrimonial process.

    What this asks of conferences (like the USCCB). The conferences are charged with helping bishops re-localize tribunal access — especially in regions where geographic distance, language, or expense have effectively excluded petitioners from the process. The reform’s success was framed by Pope Francis as depending on episcopal-conference-level coordination, not only diocesan-level action.

  7. The appeal to the Apostolic See

    It is necessary, however, to preserve the appeal to the ordinary Tribunal of the Apostolic See — that is, the Roman Rota — in respect of the ancient juridical principle, so that the bond between the See of Peter and the particular Churches may be strengthened, taking care, in the discipline of such appeal, to restrain any abuse of the law, lest harm come to the salvation of souls.

    The Rota stands. The reform did not abolish the Rota; it preserved it as the appellate forum of the Apostolic See. Either party may always appeal to the Rota (CIC can. 1680 §1). The Rota also remains a court of jurisprudence whose decisions guide tribunals worldwide. The qualifier — “taking care … to restrain any abuse” — underlies the introduction of the “manifestly dilatory” rejection-of-appeal provision (CIC can. 1680 §2).

  8. The provisions for the Eastern Churches

    As regards the Eastern Churches, I have considered separately the canonical disciplines of those Churches, mindful of the peculiarities of their juridical and pastoral tradition, with care to safeguard the proper distinctions in the Code of Canons of the Eastern Churches.

    The Eastern parallel. The companion motu proprio Mitis et misericors Iesus, issued on the same date, makes parallel reforms to the Codex Canonum Ecclesiarum Orientalium (CCEO), the code of the twenty-three sui iuris Eastern Catholic Churches. The substantive principles (single executive sentence, sole judge faculty, the briefer process) are the same; the canonical numbering and some terminology differ.

Section III

Ratio procedendi, art. 14 §1 — circumstances that permit the briefer process

Ratio procedendi · Art. 14 §1 Annexed to the motu proprio

The enumerated circumstances permitting the briefer process

§1. Among the circumstances that can permit the handling of a case for the nullity of marriage through the briefer process according to cann. 1683–1687 are included, for example: the defect of faith which can generate simulation of consent or error that determines the will; the brevity of conjugal cohabitation; an abortion procured to avoid procreation; obstinate persistence in an extramarital affair at the time of the wedding or immediately afterwards; the deceitful concealment of sterility, or of a serious contagious disease, or of children from a previous relationship, or of imprisonment; a reason for the marriage entirely foreign to married life or consisting of the unplanned pregnancy of the woman, the physical violence inflicted to extort consent, the lack of use of reason proved by medical documents, etc.

What this article does. It enumerates — non-exhaustively, with “for example” and “etc.” — the circumstances in which a case may be sent to the briefer process before the bishop instead of the ordinary process. The enumeration is illustrative, not closed; the operative test, set in CIC can. 1683, is whether the nullity is supported by “particularly clear arguments” and both spouses petition or one petitions with the other’s consent. Where either gate fails, the case is routed to the ordinary process; the briefer process is not available against the will of a participating respondent who contests the claim of nullity.

What it means for you. If your case turns on a circumstance named or analogous to one named in this article — for example, your former spouse concealed an extramarital affair active at the time of the wedding, or there was a procured abortion to avoid procreation, or the marriage was contracted under physical coercion — and your former spouse either joins the petition or does not contest it, ask your advocate or the judicial vicar whether the briefer process applies. The decision is made by the judicial vicar in the joinder-of-issue decree (CIC can. 1676 §2). Where granted, the case will be decided by the bishop personally; where denied, the case proceeds through the ordinary process — not a downgrade, simply a different track for a case that does not meet both gates.

What it does not say. The article does not say that these circumstances are grounds of nullity. They are indicators — factual patterns that frequently correlate with one of the substantive grounds of nullity (most commonly: simulation under can. 1101 §2; error under can. 1097; deceit under can. 1098; defect of due discretion under can. 1095, 2°; or duress under can. 1103). The tribunal must still adjudicate the substantive ground; the briefer process is a procedural acceleration, not a substantive presumption of nullity.

Section IV

Ratio procedendi, art. 15 — when the briefer process must not be used

Ratio procedendi · Art. 15 Annexed to the motu proprio

Cases excluded from the briefer process

Should the libellus be proposed for instituting an ordinary process, but the judicial vicar holds that the case can be handled through the briefer process, he, in the act of notifying the libellus, according to the norm of can. 1676 §1, should invite the party who did not sign the libellus to make known to the tribunal whether he or she wants to associate himself or herself with the petition presented and to participate in the trial. He, every time it is necessary, should invite the party or parties, who signed the libellus, to integrate it according to the norm of can. 1684, so that the case can be handled through the briefer process.

What this article does. It instructs the judicial vicar, on receipt of a libellus filed for the ordinary process, to consider whether the briefer process is available — that is, whether both spouses agree to proceed and whether the supporting arguments are particularly clear — and to invite the non-signing party to associate with the petition where appropriate. The reform actively presumes the judicial vicar will route cases to the briefer process when both gates are met; the briefer process is not a fallback but a preferred path for the cases that qualify.

The negative implication. Where the respondent declines to join (or to consent to) the petition, the briefer process is unavailable — the case must proceed by the ordinary process. The respondent retains, by canonical right, the standing to be heard, to be cited, and to participate; the reform did not deprive the respondent of process.

Section V

Ratio procedendi, selected other articles

Ratio procedendi · Art. 3 Pre-judicial / pastoral inquiry

The diocesan service of consultation and accompaniment before the case opens

The pre-judicial or pastoral investigation, which welcomes the separated faithful or those divorced who doubt the validity of their own marriage or are convinced of the nullity of the same, in the structures of parochial or diocesan pastoral care, will lead to the gathering of useful elements for the eventual introduction of a matrimonial cause among the faithful, judicial or administrative.

What this article authorizes. The pre-judicial inquiry — in most US dioceses a meeting (or series of meetings) with the parish priest, a deacon, or a diocesan pastoral worker before any libellus is filed — is named for the first time in the universal law. It is not a tribunal proceeding; it is the place where a Catholic who suspects the nullity of his marriage sits down with the Church and is heard. The fruit of that inquiry, if a case is to be opened, is the early framing of grounds and the early identification of witnesses. Many dioceses have institutionalized this as the “consultation” or “preliminary inquiry” step before the formal libellus is drafted.

Ratio procedendi · Art. 4 Reach of the inquiry

What the pre-judicial inquiry is to do

This pastoral inquiry gathers the useful elements to introduce, on behalf of the parties, before the competent tribunal, the cause of nullity of marriage. It investigates, with all due diligence, whether or not there are grounds to support a positive judgment regarding the nullity of the marriage.

The diagnostic function. The inquiry is, in practice, the first place the question of grounds is raised. A trained intake worker reads the petitioner’s history against can. 1095, can. 1096, cann. 1097–1099, can. 1101, can. 1102, can. 1103, can. 1108 — the canonical grounds — and helps the petitioner see which ones may apply. The Companion’s canonical-grounds diagnostic is designed to give a petitioner the same map before the first meeting with the tribunal.

Ratio procedendi · Art. 7 Free access in the briefer process

Free access where possible

§1. Taking into account the protection of the principle of remuneration, in accordance with art. 7 §1, the Episcopal Conferences should ensure that, given the security of just remuneration for the tribunal’s ministers, the gratuitousness of the procedure be assured, insofar as possible, given that the Church, showing the faithful in such close question of salvation a generous love, manifests the gratuitous love of Christ by which we have all been saved.

The cost dimension. Pope Francis named, in art. 7 of the Ratio, the goal of gratuitousness — that no Catholic should be unable to bring a case for canonical reasons because of money. In practice, US dioceses charge a modest filing fee (typically $0–$1,200 depending on diocese, sometimes structured as a sliding-scale or waivable cost); the Episcopal Conference’s 2016 guidance affirmed this principle.

What it means for you. If a fee is a barrier, say so to the judicial vicar’s office in writing. Most dioceses have a written fee-waiver policy that is rarely invoked because petitioners do not know it exists. The cost of the case is not, in canonical principle, a gate to the case.

Section VI

Implementation, in-force date, and the Eastern parallel

Final dispositions

When the reform took effect, and how to read it alongside the Code

The dispositions of these present Letters, given as Motu Proprio, will enter into force after a vacatio legis, on 8 December 2015, Solemnity of the Immaculate Conception of the Blessed Virgin Mary. With the entry into force of the present Letters, the dispositions of cann. 1671–1691 of the Code of Canon Law are abrogated and substituted by the following dispositions.

The vacatio legis. The motu proprio was signed 15 August 2015 (Solemnity of the Assumption of the Blessed Virgin Mary) but did not take effect until 8 December 2015 (Solemnity of the Immaculate Conception). All cases libelled on or after that date proceed under the new norms; cases libelled before that date but still in instruction transitioned on a tribunal-by-tribunal basis under transitional norms issued by the Apostolic Signatura.

How to read the motu proprio alongside the Code. The Code is the operative law. Mitis Iudex rewrote cann. 1671–1691; those canons are now read in their new form (walked verbatim in the CIC entry). The Ratio procedendi is supplementary — it is not part of the Code but is the universal norm for the procedural practice the reform introduced, and tribunals are bound by it. The preamble is interpretive: it is consulted when the meaning of a Code change or a Ratio article is contested.

The Eastern Catholic parallel. Mitis et misericors Iesus, issued on the same day, makes parallel changes to the CCEO. A Maronite Catholic, a Ukrainian Greek Catholic, a Melkite, a Chaldean — any of the twenty-three Eastern Catholic Churches in communion with Rome — will see his case run in substantially the same shape (single executive sentence, sole judge faculty, briefer process before the eparch), but the canonical numbering and tribunal terminology will differ. If you are an Eastern Catholic, the eparchial chancery, not the Latin tribunal, is the place to begin.
