#1. Legislative History

No. 1 The introduction of the proportional system for National Council elections was adopted by popular vote on 13 October 1918, after the people had rejected three earlier initiatives. This historic turning point ended the majoritarian electoral system that had been in place since 1848 and led to a fundamental transformation of the political landscape.

No. 2 The 1999 constitutional revision adopted the existing regulation materially unchanged (BBl 1997 I 1, 370). The constitutional legislator deliberately refrained from a new regulation of controversial issues such as the relevant population figure for seat allocation or constituency division.

#2. Systematic Classification

No. 3 Art. 149 BV stands in the systematic context of the provisions on the Federal Assembly (Title 5, Chapter 1). The norm is closely linked with:

• → Art. 150 BV (Council of States) as the second parliamentary chamber
• → Art. 34 BV (political rights) as a general electoral rights guarantee
• ↔ Art. 8 para. 1 BV (legal equality) regarding equality of voting power
• → Art. 136 BV (political rights) with respect to eligibility

No. 4 As lex specialis, Art. 149 BV takes precedence over the general electoral rights guarantee of Art. 34 BV (Judgment 1C_322/2015 of 19.8.2015 consideration 3.3). This is particularly significant for assessing proportional fairness and cantonal constituency division.

#3. Elements of the Offence / Normative Content

#Representatives of the People (para. 1)

No. 5 The 200 National Councillors represent the people, not their cantons. This characterisation fundamentally distinguishes the National Council from the Council of States and establishes the free mandate without obligation to follow instructions.

No. 6 The determination of 200 seats was made in 1962 (AS 1963 847). This number represents a compromise between adequate representation and the working capacity of parliament.

#Proportional System (para. 2)

No. 7 The "principle of proportional representation" requires seat allocation according to the vote shares of the parties. The Federal Act on Political Rights specifies this through the Hagenbach-Bischoff procedure (BGE 129 I 185 consideration 7.1.1).

No. 8 The "direct election" excludes electoral colleges and guarantees direct legitimacy by the electorate. The four-year legislative period with complete renewal ensures periodic democratic accountability.

#Constituencies (para. 3)

No. 9 The designation of cantons as constituencies is a deliberate federalist decision. This historically developed division enjoys high legitimacy (Judgment 1C_322/2015 of 19.8.2015 consideration 4.3).

No. 10 The cantonal constituency division leads to considerable differences in proportional fairness. In small cantons with few seats, equality of success value is structurally limited (Garrone, L'élection populaire en Suisse, 182 ff.).

#Seat Distribution (para. 4)

No. 11 The "population figure" as the distribution key is not conclusively defined. The Federal Council takes the position that the permanent resident population including foreigners should be decisive, as they pay customs duties and taxes just as Swiss citizens do.

No. 12 The guarantee of at least one seat per canton privileges small cantons and breaks through the pure proportional principle in favour of federalist consideration.

#4. Legal Consequences

No. 13 Art. 149 BV establishes:

• The subjective right to participate in National Council elections under the proportional system
• The entitlement of cantons to at least one National Council seat
• The obligation to conduct complete renewal elections every four years
• The prohibition of constituency changes without constitutional revision

No. 14 The constitutional norm has direct effect and requires specification by the Federal Act on Political Rights (SR 161.1) only in technical details.

#5. Controversies

#Basis for Calculating Seat Distribution

No. 15 It is disputed which population is decisive for seat distribution:

• Federal Council: The permanent resident population including foreigners should be considered
• Thurnherr: This line of argumentation disregards the mismatch between the representatives and the persons they represent
• Schumacher: Advocates for considering only those entitled to vote (ZBl 1999, 524 f.)

#Proportional Fairness in Small Cantons

No. 16 Doctrine controversially discusses whether the factual disadvantage of small parties in cantons with few seats is constitutional:

• Garrone: Sees this as a systemic but problematic inequality (L'élection populaire, 186)
• Vatter: Emphasises the federalist legitimacy of this distortion (Das politische System, 242)
• Weber: Calls for improvements in "proportional accuracy" within the existing system (AJP 2010, 1378 ff.)

#6. Practical Guidelines

No. 17 In electoral appeals, note that:

• Art. 149 BV as lex specialis takes precedence over Art. 34 BV
• The Federal Act on Political Rights conclusively regulates the procedure
• Recounts are subject to the special rules of Art. 11 VPR, not general voting jurisprudence (BGE 138 II 5)

No. 18 For constitutional revisions concerning the electoral system:

• Changes to constituency division require a constitutional amendment
• The proportional system cannot be modified at the legislative level
• International obligations (→ Art. 25 UN Covenant II) must be observed

No. 19 Practical implementation occurs through:

• Federal Act on Political Rights (SR 161.1)
• Ordinance on Political Rights (SR 161.11)
• Cantonal implementing provisions within the framework of federal requirements

#Electoral System and Proportional Principle

Judgment 1C_322/2015 of 19.8.2015 E. 3.2 Appeal against the announcement of the National Council election in the Canton of Zug; constitutional conformity of the seat allocation procedure. The judgment confirms the constitutional basis of the National Council electoral system under Art. 149 BV.

«National Council elections are regulated in the Federal Constitution and in the Federal Act on Political Rights. According to Art. 149 para. 2 BV, the members of the National Council are determined by the people in direct election according to the principle of proportional representation, with a complete renewal taking place every four years. Each canton forms an electoral district (Art. 149 para. 3 BV), and the seats are distributed to the cantons according to population size, with each canton being entitled to at least one seat (Art. 149 para. 4 BV).»

Judgment 1C_322/2015 of 19.8.2015 E. 3.3 Procedure-specific interpretation of Art. 149 BV in relation to Art. 34 BV. The Federal Court holds that Art. 149 BV stands as lex specialis in relation to the general electoral rights guarantee.

«The electoral system provided for in the Federal Act may not meet the Federal Court's requirements for an electoral system in cantonal and municipal proportional elections according to Art. 34 BV. The question arises whether the current electoral procedure of simple proportional representation is not already bindingly predetermined in Art. 149 BV and whether this constitutional provision takes precedence over Art. 34 BV as lex specialis.»

#Interpretation in Conformity with International Law

Judgment 1C_322/2015 of 19.8.2015 E. 4.3 Compatibility of the National Council electoral system with Art. 25 UN Covenant II. The federal structure of the electoral district division according to cantons is considered justified under international law.

«The Federal Constitution expressly establishes in Art. 149 para. 3 BV the traditionally federally determined cantonal territories as electoral districts. This division dates back to the introduction of the proportional electoral system for National Council elections in the popular vote of 13 October 1918, thus has a pronounced historical as well as federal reference and accordingly has high legitimacy.»

#Recount in Case of Tied Votes

BGE 138 II 5 of 1.1.2011 E. 2.2 Entitlement to recount in National Council electoral procedure. The Federal Court specifies the specific requirements for National Council elections under proportional procedure.

«Federal legislation regulates the election of the National Council under proportional procedure exhaustively; in particular, the question of whether and when a recount is to be carried out is regulated in Art. 11 VPR. The practice established with BGE 136 II 132 for votes is not applicable in this area.»

BGE 138 II 5 of 1.1.2011 E. 2.3 Particularities of the National Council electoral procedure compared to federal votes. The case law underlines the special legislative regulation of National Council elections.

«The case law established in BGE 136 II 132, according to which a very close result in a federal popular vote constitutes an 'irregularity' within the meaning of Art. 77 para. 1 lit. b BPR and grants entitlement to a recount, is not applicable to the election of the National Council under proportional procedure (Art. 77 para. 1 lit. c BPR), because the procedure is characterized by urgency and is regulated in detail by the BPR.»

#Historical Development

BGE 129 I 185 of 18.12.2002 E. 7.1.1 Foundations of the seat allocation procedure according to Hagenbach-Bischoff. The judgment confirms the legislative design of the proportional principle anchored in Art. 149 BV.

«The law essentially establishes seat allocation according to the Hagenbach-Bischoff distribution system (particularly according to Art. 40 ff. BPR).»
