Canon 29. General decrees, by which a competent legislator makes common provisions for a community capable of receiving a law, are true laws and are regulated by the provisions of the canons on laws.

Decreta generalia, quibus a legislatore competenti pro communitate legis recipiendae capaci communia feruntur praescripta, proprie sunt leges et reguntur praescriptis canonum de legibus.

Canon 30. A general decree, as in can. 29, cannot be made by one who has only executive power, unless in particular cases this has been expressly authorised by the competent legislator in accordance with the law, and provided the conditions prescribed in the act of authorisation are observed.

Qui potestate exsecutiva tantum gaudet, decretum generale, de quo in can. 29, ferre non valet, nisi in casibus particularibus ad normam iuris id ipsi a legislatore competenti expresse fuerit concessum et servatis condicionibus in actu concessionis statutis.

Canon 31. §1 Within the limits of their competence, those who have executive power can issue general executory decrees, that is, decrees which define more precisely the manner of applying a law, or which urge the observance of laws.

§2 The provisions of can. 8 are to be observed in regard to the promulgation, and to the interval before the coming into effect, of the decrees mentioned in §1.

§1. Decreta generalia exsecutoria, quibus nempe pressius determinantur modi in lege applicanda servandi aut legum observantia urgetur, ferre valent, intra fines suae competentiae, qui potestate gaudent exsecutiva.

§2. Ad decretorum promulgationem et vacationem quod attinet, de quibus in §1, serventur praescripta can. 8.

Canon 32. General executory decrees which define the manner of application or urge the observance of laws, bind those who are bound by the laws.

Decreta generalia exsecutoria eos obligant qui tenentur legibus, quarum eadem decreta modos applicationis determinant aut observantiam urgent.

Canon 33. §1 General executory decrees, even if published in directories or other such documents, do not derogate from the law, and any of their provisions which are contrary to the law have no force.

§2 These decrees cease to have force by explicit or implicit revocation by the competent authority, and by the cessation of the law for whose execution they were issued. They do not cease on the expiry of the authority of the person who issued them, unless the contrary is expressly provided.

§1. Decreta generalia exsecutoria, etiamsi edantur in directoriis aliusve nominis documentis, non derogant legibus, et eorum praescripta quae legibus sint contraria omni vi carent.

§2. Eadem vim habere desinunt revocatione explicita aut implicita ab auctoritate competenti facta, necnon cessante lege ad cuius exsecutionem data sunt; non autem cessant resoluto iure statuentis nisi contrarium expresse caveatur.

Canon 34. §1 Instructions, namely, which set out the provisions of a law and develop the manner in which it is to be put into effect, are given for the benefit of those whose duty it is to execute the law, and they bind them in executing the law. Those who have executive power may, within the limits of their competence, lawfully publish such instructions.

§2 The regulations of an instruction do not derogate from the law, and if there are any which cannot be reconciled with the provisions of the law they have no force.

§3 Instructions cease to have force not only by explicit or implicit revocation by the competent authority who published them or by that authority’s superior, but also by the cessation of the law which they were designed to set out and execute.

§1. Instructiones, quae nempe legum praescripta declarant atque rationes in iisdem exsequendis servandas evolvunt et determinant, ad usum eorum dantur quorum est curare ut leges exsecutioni mandentur, eosque in legum exsecutione obligant; eas legitime edunt, intra fines suae competentiae, qui potestate exsecutiva gaudent.

§2. Instructionum ordinationes legibus non derogant, et si quae cum legum praescriptis componi nequeant, omni vi carent.

§3. Vim habere desinunt instructiones non tantum revocatione explicita aut implicita auctoritatis competentis, quae eas edidit, eiusve superioris, sed etiam cessante lege ad quam declarandam vel exsecutioni mandandam datae sunt.
