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.
