1The Federal Assembly shall enact provisions that establish binding legal rules in the form of federal acts or ordinances.
2Other enactments are promulgated in the form of a federal decree; a federal decree that is not subject to a referendum is known as a “simple federal decree”.
Overview
Article 163 of the Federal Constitution regulates the forms in which the Federal Assembly (Parliament) may adopt its decisions. The provision distinguishes between two main categories of parliamentary decisions.
Two forms are available for legislative provisions. Federal acts are the normal form for new rules that apply to all citizens. They may be rejected by the people at the ballot box (optional referendum). Examples include the Criminal Code or the Employment Act. Ordinances of the Federal Assembly are rarer and are used only in emergencies or when the law expressly permits this.
All other parliamentary decisions are issued as federal decrees. These are divided into two groups: those subject to referendum and simple federal decrees without the possibility of referendum. Simple federal decrees mainly concern internal parliamentary matters such as elections, the budget, or the approval of certain international treaties.
The choice of the correct form is important because it determines whether the people can participate in the decision-making process. In the case of federal acts, the people always have the final say if sufficient signatures are collected. In the case of simple federal decrees, this possibility does not exist.
A practical example: If Parliament wants to introduce new traffic rules, it must enact a federal act. The people can then launch a referendum. If, however, it wants to elect the Federal Council, this is done through a simple federal decree without the possibility of referendum.
N. 1 Art. 163 Cst. stems from the total revision of the Federal Constitution of 1999. The provision corresponds largely in content to Art. 5 para. 1 old Constitution (1874), but specifies the various forms of enactment of the Federal Assembly. The Message on a new Federal Constitution of 20 November 1996 (BBl 1997 I 1) emphasises that the norm "explicitly names the various types of enactment of the Federal Assembly" (BBl 1997 I 412). The constitutional revision aimed to anchor constitutionally the distinctions between various forms of enactment that had been developed in practice.
N. 2 The explicit mention of ordinances as a law-making form of enactment in para. 1 was an innovation compared to the old Federal Constitution. This codified the practice that the Federal Assembly can itself issue ordinances in certain cases, for example in urgent measures or when the law expressly provides for this (BBl 1997 I 412).
N. 3 Art. 163 Cst. is located in Title 5 on the Federal Authorities, in Chapter 1 on the Federal Assembly. The provision defines the forms of action of Parliament and is closely linked with:
→ Art. 164 Cst. (Legislation, in particular statutory form)
→ Art. 165 Cst. (Emergency law)
→ Art. 141 Cst. (Optional referendum)
→ Art. 141a Cst. (Mandatory referendum)
N. 4 The norm forms, together with Art. 164 Cst., the cornerstone of the parliamentary legislative procedure. While Art. 163 Cst. regulates the forms of enactment, Art. 164 Cst. determines which matters must mandatorily be enacted in statutory form (principle of legality).
N. 5 Law-making provisions are general-abstract norms that cover an indefinite multitude of addressees and situations. According to doctrine (Häfelin/Haller/Keller/Thurnherr, Schweizerisches Bundesstaatsrecht, 10th ed. 2020, N 1843), law-making enactments are characterised by the following features:
Generality (indefinite multitude of addressees)
Abstraction (indefinite multitude of situations)
External binding effect
N. 6 The Federal Assembly has two forms available for law-making provisions:
Federal Act: The ordinary form for law-making enactments. Federal acts are subject to the optional referendum (→ Art. 141 para. 1 lit. a Cst.) and must go through the ordinary legislative procedure.
Ordinance of the Federal Assembly: An extraordinary form that is only applied in cases provided for by law or in cases of urgency. Rhinow/Schefer/Uebersax (Schweizerisches Verfassungsrecht, 3rd ed. 2016, N 2848) emphasise the exceptional character of parliamentary ordinances.
N. 12 The distinction between law-making and non-law-making enactments is disputed in doctrine. While Tschannen/Zimmerli/Müller (Allgemeines Verwaltungsrecht, 4th ed. 2014, § 20 N 15) argue for a formal approach, Müller (in: St. Galler Kommentar BV, 4th ed. 2023, Art. 163 N 8) advocates a material distinction according to the content of the norm.
N. 13 The admissibility of individual case laws is also controversially discussed. Häfelin/Haller/Keller/Thurnherr (op. cit., N 1851) recognise their admissibility in exceptional cases, while Biaggini (BV-Kommentar, 2nd ed. 2017, Art. 163 N 4) is more restrictive and points to the danger of circumventing the separation of powers.
N. 14 Regarding parliamentary ordinances, there is disagreement about their scope of application. Ehrenzeller (in: St. Galler Kommentar BV, 4th ed. 2023, Art. 163 N 15) sees these as limited to cases of urgency, while Waldmann (in: BSK BV, 2nd ed. 2024, Art. 163 N 22) also recognises other cases provided for by law.
N. 15 In choosing the form of enactment, the content is primarily decisive: If general-abstract regulations with external effect are to be created, a law-making form (Federal Act or ordinance) must mandatorily be chosen. The designation by the Federal Assembly is not decisive (BGE 128 II 66 E. 2.2).
N. 16 Significant for practice is the ability to hold a referendum: If an enactment is to be subject to the optional referendum, the form of a Federal Act or of a federal decree subject to referendum must be chosen. The subsequent change of the form of enactment is not possible.
N. 17 For international treaties, it should be noted: Approval takes place through federal decree, whereby depending on the content of the treaty, the optional or mandatory referendum applies (→ Art. 140 para. 1 lit. b Cst., Art. 141 para. 1 lit. d Cst.). The federal decree on approval is not a law-making enactment within the meaning of Art. 163 para. 1 Cst.
Case Law
#Distinction between legislative and non-legislative enactments
BGE 128 II 66 of 6 November 2001
Constitutional appeal as the only admissible legal remedy against cantonal legislative enactments.
The judgment confirms the central importance of the distinction between legislative and non-legislative enactments for the legal remedies system.
