On 2 June 2002, voters in Vaud and Geneva jointly buried the most ambitious institutional project French-speaking Switzerland had ever seen: the "Oui à la région!" initiative, which called for the launch of a merger process between the two cantons. The verdict was unambiguous — roughly 77 per cent No in Vaud and 80 per cent in Geneva (85,623 No against 21,435 Yes in Geneva, on a 51.6 per cent turnout).
The idea was born in 1997 from an appeal published simultaneously in the Journal de Genève and the NZZ, signed by two former cantonal ministers — Vaud Radical Philippe Pidoux and Geneva Socialist Bernard Ziegler. Their diagnosis: the Lake Geneva arc forms a single living and labour basin, yet remains governed by two administrations, two tax systems and two bodies of law. The Union Vaud-Genève association gathered signatures in both cantons and forced a coordinated vote on the same Sunday.
Nearly a quarter of a century later, the question the initiators raised — how to govern a region that outgrows its borders — has lost none of its relevance. But the answer the two cantons chose was institutionalised cooperation, not marriage.
▲ The result in Vaud No at roughly 77 per cent. Not a single Vaud district accepted the initiative; rejection was uniform, from the lakeside cities to the rural Gros-de-Vaud and the canton's north. | ▼ Across the Versoix Geneva refused even more bluntly: 80 per cent No (85,623 votes to 21,435) on a 51.6 per cent turnout. Four voters out of five, on either side of the cantonal border, said no. |
Key players
▲ Yes camp • Philippe Pidoux (former Vaud minister, Radical, co-author of the 1997 appeal) • Bernard Ziegler (former Geneva minister, Socialist, co-author of the appeal) • Union Vaud-Genève (initiative committee) • Pierre Maudet (young Geneva Radical, future cantonal minister, campaign manager) | ▼ No camp • Vaud government (including finance minister Pascal Broulis) • Geneva government (unanimously opposed) • Ligue vaudoise (traditionalist movement, spearhead of the identity-based No) • Nearly all cantonal parties (Liberals, official Radicals, SVP, Christian Democrats, most of the left) |
Arguments and verdicts — almost 24 years on
▲ Arguments FOR (Yes camp) Cantonal borders are obsolete: the Lake Geneva region must unite to matter. "Many people share the view that cantonal borders are obsolete." — Pierre Maudet, campaign manager, in Le Temps ✓~ Partially confirmed The diagnosis proved correct: the Lake Geneva basin kept functioning as a single region — so much so that Vaud and Geneva created the Métropole lémanique in 2011 to speak with one voice in Bern, plus the cross-border Grand Genève. But the political conclusion — merging — never prevailed: cooperation sufficed. Source: Le Temps (2002); ge.ch, ten-year review of the Métropole lémanique (2021) A single canton would bring rationalisation, simplification and economies of scale. The initiators promised better framework conditions through fiscal and legislative simplification. — Union Vaud-Genève campaign material, as reported in the press ✗~ Partially refuted The argument was never tested, but the facts drained it of its force: without any merger, the region obtained Léman 2030, the Léman Express and sustained economic prosperity. Two administrations, two tax systems and two bodies of law still coexist — without regional development being held back. Source: SBB/Léman 2030; grand-geneve.org | ▼ Arguments AGAINST (No camp) Cantonal identities are non-negotiable; the merger is an artificial construct doomed to fail. "The canton of Vaud is a little Switzerland of its own, with its lake, its plateau and its mountains." — Pascal Broulis, Vaud minister, in the campaign press ✓ Confirmed The 77 and 80 per cent rejections vindicated the identity-based diagnosis, and history sealed it: in nearly a quarter of a century, no party, no government and no committee has seriously revived the idea of a Vaud-Geneva merger. Source: Le Temps, "L'idée d'une fusion entre Vaud et Genève est enterrée pour longtemps"; Tribune de Genève (2022) No merger needed: intercantonal cooperation can solve the shared problems. The Ligue vaudoise and both governments championed collaboration between sovereign cantons over mutual absorption. — Ligue vaudoise pamphlet "Vaud-Genève: unis contre la fusion" ✓ Confirmed That is precisely the scenario that unfolded: the Métropole lémanique convention (2011), joint pre-financing of the Léman 2030 rail programme, the Léman Express launched in 2019, the cross-border Grand Genève. Cooperation delivered most of what the merger had promised. Source: FAO VD / ge.ch (2021); grand-geneve.org |

What the region built without merging | ge.ch · FAO VD · grand-geneve.org · SBB |
| ✓ | Métropole lémanique (2011) — the Vaud and Geneva governments signed a convention to defend their interests jointly in Bern: transport, healthcare, taxation. The ten-year review (2021) highlights the cantonal pre-financing of major rail works. |
| ✓ | Léman 2030 and the Léman Express — a framework agreement with the Confederation and SBB to expand rail capacity between Lausanne and Geneva; the cross-border Léman Express commuter network, launched in December 2019, became Europe's largest cross-border regional rail network. |
| ~ | Grand Genève — the Franco-Vaud-Geneva agglomeration (a GLCT public body since 2013, over one million inhabitants) has co-financed more than 1.6 billion francs of measures with the Confederation. Yet its governance remains fragile: lacking direct democratic legitimacy, it depends on members' goodwill. |
| ~ | The borders have not gone away — cross-border-worker taxation, intercantonal fiscal equalisation, tax competition and hospital planning still require negotiations between two sovereign states. The problem the initiators identified remains; only their solution was discarded. |
Twenty-four years on, the vote of 2 June 2002 stands as one of the great clarifying moments of federalism in French-speaking Switzerland. The opponents won twice: massively at the ballot box, then on the facts, since the intercantonal cooperation they promised as an alternative was actually built — Métropole lémanique, Léman 2030, the Léman Express, Grand Genève.
The initiators were not entirely wrong, however. Their diagnosis — a region functioning as a single living basin, governed by structures that stop at the Versoix river — is precisely what drove the two cantons to institutionalise their alliance from 2011 onwards. History's irony is that the victors of the No went on to implement part of the losers' programme, in a lightweight version that left the flags untouched.
The political lesson endures: in Switzerland, identities cannot be merged by force of efficiency arguments. The four-to-one rejection, identical on both sides of the border, showed that a canton is an affective political community before it is an administrative unit. Every territorial redesign since — from the Bernese Jura to municipal mergers — has had to reckon with that reality.
