Art. 170 BV obliges the Federal Assembly to ensure that federal government measures are reviewed for their effectiveness. This provision is a constitutional innovation of the 1999 Federal Constitution without equivalent in the old Federal Constitution of 1874 (SGK-Uhlmann/Bussmann, Art. 170 BV, N. 1).
The Federal Assembly does not have to conduct the effectiveness reviews itself, but may delegate them to the Federal Council, to parliamentary auxiliary bodies, or to external bodies (BSK-Lienhard/Mächler/Marti Locher, Art. 170 BV, N. 11). In practice, Parliament fulfills this mandate primarily through evaluation clauses in laws that oblige the Federal Council to review certain measures. Currently, around 110 such clauses exist in federal law.
«Effectiveness» is understood in a broad sense and comprises three sub-criteria (SGK-Uhlmann/Bussmann, Art. 170 BV, N. 20 ff.): the implementation status (is the measure actually implemented?), the degree of objective achievement (does the measure achieve its objectives?), and economic efficiency (are costs and benefits in reasonable proportion?).
The subject of effectiveness reviews are all «federal measures», regardless of their legal form. This includes not only measures of the federal government and federal administration, but also laws of Parliament, decisions of the federal courts, and even the actions of the Federal Assembly itself (SGK-Uhlmann/Bussmann, Art. 170 BV, N. 18).
A concrete example: The Federal Act on International Child Abduction was systematically reviewed based on an evaluation clause to determine whether the legal instruments for protecting abducted children actually function effectively. Such evaluations can lead to the adaptation or improvement of laws.
However, Art. 170 BV is not justiciable. Individuals cannot claim an entitlement to the conduct of specific effectiveness reviews (SGK-Uhlmann/Bussmann, Art. 170 BV, N. 31). The decision of which measures are reviewed when and how lies in the political discretion of the Federal Assembly.
The provision is intended to ensure that government measures are not only formally correctly enacted, but also practically effective. It thereby contributes to democratic accountability and supports evidence-based policy-making in Switzerland.
N. 1 Art. 170 BV represents a constitutional innovation that has no equivalent in the old Federal Constitution of 1874. The express anchoring of effectiveness review only gained entry into the revision process for the new Federal Constitution at a late stage. The constitutional drafts of 1995/96 did not yet contain a corresponding provision.
N. 2 The expert commission of both parliamentary supervisory committees initially proposed the creation of an independent body for the evaluation of state measures. Instead, the parliamentary supervisory committees linked effectiveness review to the Federal Assembly's supreme oversight competence in their supplementary report of 1997. This conception remained during parliamentary deliberations, whereby effectiveness review was extracted as an independent provision from the current Art. 169 BV (BSK-Lienhard/Mächler/Marti Locher, Art. 170 BV, N. 1 ff.; SGK-Uhlmann/Bussmann, Art. 170 BV, N. 1 ff.).
N. 3 According to the materials, the constitutional provision aimed to manage the increasing complexity of public tasks through systematic review. Rapporteur Schmid stated in the National Council debate: «The question of the effectiveness, efficacy and efficiency of state measures is becoming increasingly important against the background of the growing complexity of public tasks. Do the measures taken by the authorities have any effect at all? Do they show the intended effect? Are they in a reasonable cost-benefit ratio?» (AB N SD 1998, 91).
N. 4 Art. 170 BV stands in the 3rd section («Competences») of the 2nd chapter on federal authorities. The provision anchors a competence and guarantee mandate of the Federal Assembly. It has a close systematic connection to supreme oversight under Art. 169 BV, but goes beyond it in two respects.
N. 5 Firstly, Art. 170 BV particularly emphasises the standard of effectiveness, while supreme oversight under Art. 169 BV is not limited to this standard. Secondly, the provision extends the Federal Assembly's review mandate beyond the subject matter of Art. 169 BV, particularly regarding measures by the constitutional and legislative authorities (SGK-Uhlmann/Bussmann, Art. 170 BV, N. 18; Biaggini, Art. 170 BV, N. 4).
N. 6 Art. 170 BV stands in systematic connection with further constitutional provisions that demand effective state task fulfilment: Art. 5 BV (rule of law principle), Art. 8 BV (equality before the law), Art. 9 BV (prohibition of arbitrariness), Art. 35 BV (realisation of fundamental rights), Art. 36 BV (proportionality), Art. 43a para. 5 BV (needs-based fulfilment of state tasks), Art. 126 para. 1 BV (budget management) and Art. 178 para. 1 BV (appropriate organisation of the administration).
N. 7 The constitutional mandate is directed at the Federal Assembly as addressee. The democratic dimension of effectiveness review is thus emphasised: The people's representatives bear ultimate responsibility for ensuring that state measures serve the common good.
N. 8 The organs of the Federal Assembly (Art. 31 ParlA) are tasked with ensuring effectiveness review. The parliamentary committees ensure effectiveness review in their areas of competence (Art. 44 para. 1 lit. e ParlA) and take into account the results of effectiveness reviews (Art. 44 para. 1 lit. f ParlA).
b) Guarantee Mandate
N. 9 The formulation «ensures that» establishes a guarantee mandate. The Federal Assembly need not conduct the reviews itself, but may delegate them. It may give the Federal Council a mandate (Art. 27 lit. a ParlA), review effectiveness reviews conducted by the Federal Council (Art. 27 lit. b ParlA) or commission effectiveness reviews itself (Art. 27 lit. c ParlA).
N. 10 The Federal Audit Office (FAO) and the Parliamentary Administration Control (PAC) serve as permanent auxiliary bodies. The FAO focuses on the aspect of economic efficiency (Art. 5 para. 2 FAA), while the PAC conducts evaluations on behalf of the supervisory committees within the framework of parliamentary supreme oversight (Art. 10 para. 1 lit. a ParlO).
c) Federal Measures
N. 11 The subject of effectiveness reviews are all «federal measures», regardless of their legal form. Measures by all three branches of government are covered: legislative, executive and judicial. The term encompasses both generally abstract and individually concrete measures.
N. 12 The implementation and enforcement of federal measures by cantons and private parties also fall under the scope of application, insofar as they can be qualified as enforcement of federal law (BSK-Lienhard/Mächler/Marti Locher, Art. 170 BV, N. 17; SGK-Uhlmann/Bussmann, Art. 170 BV, N. 18).
N. 13 Non-action can also be the subject of an effectiveness review. Unlawful omissions can be just as consequential as active action (Biaggini, Art. 170 BV, N. 4; SGK-Uhlmann/Bussmann, Art. 170 BV, N. 18).
d) Effectiveness as Review Standard
N. 14 The term «effectiveness» is to be understood in a broad sense. In practice, it comprises three sub-criteria (SGK-Uhlmann/Bussmann, Art. 170 BV, N. 20 ff.):
Implementation status (effectiveness): extent and type of implementation
Goal achievement level (effectiveness in the narrow sense): achievement of regulatory objectives
Economic efficiency (efficiency): cost-benefit ratio
N. 15 Which review criteria an evaluation takes as its standard and in what weighting is context-dependent. For basic services, needs-based fulfilment is in the foreground, while in other areas economic aspects can be weighted more heavily.
N. 16 The guarantee mandate is legally binding for the Federal Assembly, but not justiciable. Individuals cannot derive a direct subjective claim to the conduct of effectiveness reviews from Art. 170 BV. The Federal Assembly has considerable discretionary scope regarding the question of whether, when and how measures are reviewed.
N. 17 The Federal Assembly regularly fulfils the mandate by enacting special legal evaluation clauses that oblige the Federal Council to conduct effectiveness reviews. Currently, approximately 110 such clauses exist in federal law (FOJ, Overview Evaluation Clauses).
N. 18 Although Art. 170 BV is directed at the Federal Assembly, the Federal Council also has the inherent competence to initiate effectiveness reviews at any time. This follows from its constitutional competences for state leadership (Art. 174 BV), planning and coordination (Art. 180 para. 1 BV) and for the enforcement of legislation (Art. 182 BV).
N. 19 The norm grants the Federal Assembly review and investigation powers without conferring additional decision-making competences or information rights (SGK-Mastronardi, 2nd ed., Art. 170 BV, N. 8; Biaggini, Art. 170 BV, N. 4).
N. 20 The question of whether Art. 170 BV establishes a constitutional principle of effectiveness of state measures is controversially discussed in legal doctrine. Flückiger derives from the provision a «principe d'efficacité» that obliges addressees to examine state measures through evaluation (CR-Flückiger, Art. 170 BV, N. 27). Mastronardi argues that the mandate for effectiveness review only makes sense if output legitimation is an objective recognised by the Federal Constitution (SGK-Mastronardi, 2nd ed., Art. 170 BV, N. 18).
N. 21 The opposing view, represented by Uhlmann/Bussmann, rejects such a constitutional principle. They argue that Art. 170 BV is not justiciable and it is systematically not convincing to derive a principle of general scope from a competence norm. A constitutional principle limited to federal measures would moreover be of little value (SGK-Uhlmann/Bussmann, Art. 170 BV, N. 31). Biaggini also expresses doubts about such a principle (Biaggini, Art. 170 BV, N. 3).
N. 22 Another point of contention concerns the scope of the review obligation for the Federal Assembly's own measures. While prevailing doctrine affirms a self-evaluation obligation of parliament (Biaggini, Art. 170 BV, N. 4; SGK-Uhlmann/Bussmann, Art. 170 BV, N. 18), it is disputed how far this obligation reaches in practice and what concrete requirements arise from it.
N. 23 When formulating evaluation clauses, the Federal Office of Justice recommends regulating the following elements: the reporting authority, the addressee of the results, the time of review, the final product as well as the criteria and subject of the review (FOJ, Recommendations Evaluation Clauses 2012, p. 4).
N. 24 Conducting evaluations involves considerable effort. Implementation analyses typically require 6 months and approximately 60,000 francs, impact analyses at least one year and 100,000 francs. For economic efficiency analyses, costs vary greatly depending on scope (FOJ, Legislative Drafting Guide 2025, N. 1166).
N. 25 The Swiss Evaluation Society (SEVAL) has developed standards to be observed in the planning and conduct of evaluations. These include criteria for assessing quality, general basic principles as well as standards for planning, conduct, assessment and communication of results (SEVAL Standards 2016).
N. 26 In practice, the Federal Council takes a more active role than parliament. The federal administration has an evaluation network with over 110 staff from all departments. When commissioning external evaluations, attention must be paid to the independence of evaluators and a results-open mandate formulation to avoid improper influences (Pleger/Sager, Influencing Evaluators, p. 23 ff.).
BGE 141 I 172 of 24 August 2015 (2C_1006/2014)
The Federal Supreme Court clarifies the nature of parliamentary high-level supervision over the administration. High-level supervision has predominantly political characteristics, which allows the cantons to provide for an exception to the guarantee of access to the courts. Relevant to Art. 170 BV is the finding that parliamentary control mechanisms are largely excluded from judicial control.
«High-level supervision has predominantly political characteristics, which allows the cantons to provide for an exception to the guarantee of access to the courts. The exclusion of the jurisdiction of cantonal judicial authorities for reviewing the exercise of parliamentary high-level supervision violates neither the prohibition of arbitrariness nor the guarantee of access to the courts.»
Judgment AU.2007.1_A of the Federal Criminal Court of 18 December 2007
This judgment deals with the information rights of parliamentary committees in the context of business audits. The court confirms that parliamentary committees possess extensive information rights in exercising their supervisory function, which gained constitutional status with the Federal Constitution of 1999.
«The information rights of parliamentary committees gained constitutional status with the Federal Constitution of 18 April 1999 and were strengthened in the sense that in case of conflict, the controlling authority and not the controlled entity decides on their exercise.»
BGE 137 I 77 of 2 February 2011 (1C_415/2010)
The Federal Supreme Court distinguishes between abstract norm control and political effectiveness review. While the former is subject to judicial review, parliamentary effectiveness review under Art. 170 BV remains reserved to the political sphere. The court clarifies the limits of judicial control over parliamentary supervisory activities.
«The cantonal legal provision is subject to appeal against enactments, whereby in the legislative process the admissibility of the prerequisites was discussed. There is thus a total revision, which is why every provision of the new law can be subjected to abstract norm control.»
Judgment 2C_280/2020 of the Federal Supreme Court of 15 April 2020
The Federal Supreme Court confirms that federal enactments are not subject to abstract norm control. This case law is relevant to Art. 170 BV as it shows the limits of judicial review of parliamentary control activity. Effectiveness reviews fall fundamentally within the sphere of political and not judicial control.
«Federal enactments are not subject to abstract norm control. The Federal Supreme Court can only examine a Federal Council ordinance preliminarily within the framework of incidental norm control for its conformity with law and constitution.»
From the practice of parliamentary business audit committees (cf. various reports of the Federal Assembly 1990-2020), it emerges that Art. 170 BV is primarily implemented through the organizational provisions of the business audit committees and the Parliamentary Administration Control. Judicial control is limited to procedural aspects, not to the material assessment of effectiveness.
Case law shows that Art. 170 BV is conceived as a programmatic norm that requires parliamentary implementation. Direct claims for effectiveness reviews cannot be derived from the norm. The control function is exercised by specialized parliamentary bodies (GPK, PVK), whose activity remains largely reserved to the political sphere.
Note on the state of case law: Art. 170 BV has a thin case law density, as it is an organizational norm that primarily regulates the internal functioning of the Federal Assembly. The cited decisions concern related aspects of parliamentary control and high-level supervision that are relevant for understanding Art. 170 BV.
