Motu Proprio is the formula by which the Roman Pontiff indicates that he issues an act on his own initiative, most commonly in an Apostolic Letter that establishes or changes law or governance.
Overview
In law, motu proprio (Latin for 'on his own impulse') describes an official act taken without a formal request from another party. Some jurisdictions use the term sua sponte for the same concept.
In Catholic canon law, it refers to a document issued by the pope on his own initiative and personally signed by him.[1] Such a document may be addressed to the whole church, to part of it, or to some individuals.[1] The first papal motu proprio was promulgated by Pope Innocent VIII in 1484.[2] It continues to be a common form of papal rescript, especially when establishing institutions, making minor changes to law or procedure, and when granting favours to persons or institutions.
Meaning and documentary form
The Latin words mean on one's own initiative. Vatican documents commonly bear the heading Apostolic Letter issued Motu Proprio, making clear that Motu Proprio and Apostolic Letter answer different questions: the former describes papal initiative, while the latter names the document form. Usage has made motu proprio a convenient noun for the resulting act, but the distinction remains useful.
Such acts frequently amend the Code of Canon Law or the Code of Canons of the Eastern Churches, create institutions, transfer competencies, approve statutes, or issue special norms. They are often concise and operational. Their title, promulgation clause, vacatio, territorial or personal scope, and transitional rules must be read together.[3]
Not merely spontaneous
The formula does not mean that the pope acted without consultation, drafting assistance, or study. It locates the juridical initiative and authorship in the Roman Pontiff rather than presenting a petitioner's favor as the source. Canon 38 itself recognizes that even a Rescript may be given motu proprio, confirming that the phrase is not confined to one legislative genre.
Legal effect and limits
Many acts issued Motu Proprio are papal laws because their operative provisions enact general norms and are duly promulgated. Others are singular or institutional acts. The phrase alone does not tell whether a norm is universal, particular, temporary, retroactive, or derogatory; those matters depend on the text and Canon Law.[4]
Canon 38 warns that a singular administrative act, even a Rescript given motu proprio, lacks effect insofar as it harms another's acquired right or contradicts law or approved custom unless competent authority expressly adds a derogating clause. Papal competence is supreme, yet sound interpretation still asks exactly what the act says and whom it binds.[5]
No magisterial shortcut
Motu Proprio does not mean ex cathedra and carries no automatic rank within Grades of Magisterial Teaching. A legislative text ordinarily expresses Church Discipline; a preamble may also contain Authoritative Doctrine. The faithful owe each element the response appropriate to its actual character.
Reading and citation
A proper entry identifies the formal heading, date of signature and promulgation, effective date, provisions amended, competent executing bodies, and subsequent corrections or authentic interpretations. Merely reporting that the pope issued a motu proprio leaves the juridical result unexplained.[6]
Capitalization varies in English, while Latin is conventionally italicized in prose. The spellings motuproprio and motu-proprio denote the same term, but not every papal initiative is legislation. The source text remains controlling.

Effect
An important effect of issuing a document in this way is that a rescript containing the clause motu proprio is valid and produces its effect even in cases where fraud would ordinarily have vitiated the document, since the pope does not rely on the reasons alleged when he grants a favour.[2] Withholding of the truth in what, according to canonical law, style and practice, must for validity be expressed, normally renders a rescript invalid, but not if the rescript is issued motu proprio.[7] Consequently, canonists traditionally called the clause the "mother of repose".[2] The designation motu proprio indicates that the validity of the document is independent of the validity of whatever reasons may have been adduced in a request for its issuance.[2]
However, a motu proprio has no effect in so far as it harms the acquired right of another or is contrary to a law[8] or approved custom, unless it expressly states that it is derogating from these matters.[9]
Form
A motu proprio rescript begins by giving the reasons for issuing it, and then indicates the law or regulation made or the favour granted. It is less formal than a constitution and carries no papal seal. Its content may be instructional (e.g., on the use of chant), administrative (e.g., concerning a church law or the establishment of a commission), or merely to confer a special favour.[10]
Civil law
More generically, this phrase (or proprio motu; Latin allows free word order) is used to indicate an act taken by a court without a motion from a party to the case. The term is used very rarely in legal opinions in the United States, where sua sponte is preferred, but proprio motu is used in Canada.[11] Proprio motu is used to refer to a decision by the prosecutor of the International Criminal Court to initiate an investigation into a situation without a referral from the Security Council or a state party; this power is granted by article 15(1) of the Rome Statute. European Court of Justice judgments use the phrase "of its own motion" and its equivalent in other community languages.[12]
As it relates to a monarch, the term motu proprio describes the condition of a royal decree being made expressly on the sovereign's initiative, a practice more usual in some nations than in others.
Relating to orders of chivalry, like the Order of Malta, the grand master according to the statutes can confer the order motu proprio, instead of in response to a nomination by a national delegation.

From the 1913 Catholic Encyclopedia
The name given to certain papal rescripts on account of the clause motu proprio (of his own accord) used in the document. The words signify that the provisions of the rescript were decided on by the pope personally, that is, not on the advice of the cardinals or others, but for reasons which he himself deemed sufficient. The document has generally the form of a decree: in style it resembles a Brief rather than a Bull, but differs from both especially in not being sealed or countersigned. It issues from the Dataria Apostolica, and is usually written in Italian or Latin. It begins by stating the reason inducing the sovereign pontiff to act, after which is stated the law or regulation made, or the favour granted, It is signed, personally by the pope, his name and the date being always in Latin. A Motu Proprio was first issued by Innocent VIII in 1484. It was always unpopular in France, where it was regarded as an infringement of Gallican liberties, for it implied that the sovereign pontiff had an immediate jurisdiction in the affairs of the French Church. The best-known recent example of a Motu Proprio is the instructions issued by Pius X on 22 November, 1903, for the reform of church music.
The phrase motu proprio is frequently employed in papal documents. One characteristic result of its use is that a rescript containing it is valid and produces its effect even in cases where fraud would ordinarily have vitiated the document, for the words signify that the pope in granting the favour does not rely on the reasons alleged. When the clause is used in dispensations, the latter are given a broad interpretation; a favour granted motu proprio is valid even when counter to ecclesiastical law, or the decisions of the pope himself. Consequently, canonists call the clause the "mother of repose": "sicut papaver gignit somnum et quietem, ita et hæc clausula habenti eam." (See RESCRIPTS.)
