On 14 October 2012, the Geneva electorate accepted, with 54.1 % yes, a new cantonal Constitution, replacing the 165-year-old text of 1847. Turnout was a low 31.9 %, and several large municipalities — the City of Geneva, Carouge, Onex, Meyrin — rejected the text that the canton was approving.
The draft had been written by an 80-member Constituent Assembly, elected in 2008 and made up of eleven groups (six on the right, five on the left). It adopted its text on 31 May 2012 (57 votes to 15, 5 abstentions) after setting aside the most divisive subjects to secure a majority. The new Constitution came into force on 1 June 2013.
Nearly fourteen years on, the text structures the cantonal legal order — and one of its creations, the Constitutional Chamber, has become a central player in Geneva politics.
▲ Municipalities that accepted A majority of suburban and outlying municipalities, enough to carry the cantonal yes to 54.1 %. | ▼ Municipalities that rejected City of Geneva, Carouge, Onex and Meyrin — rather left-leaning urban centres, where the SolidaritéS opposition took hold. |

Arguments and verdicts — nearly 14 years on
▲ Arguments FOR Replace an 1847 Constitution with a modern text, a necessary revitalisation of the social contract. « A necessary revitalisation of the social contract. » — Socialist Party, on voting night ✓ Confirmed The text came into force on 1 June 2013 and has remained part of the cantonal legal order ever since. It modernised the institutional architecture (separation of powers, courts) and a catalogue of rights that an 1847 charter ignored. Source: Geneva Chancellery; Cst-GE, RS A 2 00 Strengthen fundamental rights and ease their justiciability through new guarantees. ✓ Confirmed The new Constitution created the Constitutional Chamber of the Court of Justice, the first court of its kind in Geneva, empowered to review the conformity of cantonal laws. It has since exercised this abstract review — notably on the secularism law in 2019. The text also enshrines extended social rights (art. 38, right to housing). Source: Geneva judiciary, Constitutional Chamber | ▼ Arguments AGAINST The proclaimed rights will remain theoretical, for lack of real justiciability. « Rights that cannot be invoked before a judge. » — SolidaritéS and associations, 2012 campaign ✗~ Partly disproven The fear largely failed to materialise: it was precisely the Constitutional Chamber that enabled judicial review of cantonal acts, and several rights (housing, secularism) produced concrete effects. The text did not remain a dead letter. Source: humanrights.ch; ATF 148 I 160 (2021) The draft dodges the real debates: foreigners' eligibility, municipal taxation, territorial organisation. ✓ Confirmed This reproach proved accurate: these three subjects were deliberately set aside to secure a majority within the Assembly. They remained unresolved and fuelled separate debates in the following years. Source: RTS, 14.10.2012; Assembly proceedings |

Nearly fourteen years on, the factual verdict leans toward the supporters, without entirely proving the opponents wrong. The bet on modernisation paid off: the 1847 text did give way, and the new charter gave Geneva instruments it lacked — first among them a genuine constitutional jurisdiction.
The left-wing opponents feared a shell of toothless rights. On that point, history mostly proved them wrong: the Constitutional Chamber worked, and rights such as housing or secularism found concrete translations. But their second reproach — that the text dodged the thorny questions — was well founded. Foreigners' eligibility and municipal taxation were carefully sidestepped so as not to bring the whole edifice down.
Perhaps that is the Geneva lesson: a compromise constitution moves forward by setting aside whatever no one agrees on. That is how it wins its majority — and postpones the real battles to later.
