Automatic summary, not yet reviewed

- A candidacy would automatically get a majority of council seats (half plus one) if it wins over 35% of the vote and leads the next candidacy by five points, or if it wins over 30% and leads by ten points.
- If no candidacy meets those thresholds, a second round would be held. Only candidacies that got at least 15% of valid votes in the first round could take part.
- After the runoff, the leading candidacy would get half plus one of the council seats if it wins over 40% of the vote or leads the runner-up by at least 7 points. Otherwise, seats would be allocated based on first-round results.
- The majority bonus would only apply to parties that ran alone or on a joint list presented before the vote. The goal is to prevent later deals that push aside the most voted option.
- The Government would have one month from the law's entry into force to approve the rules needed to run the second round.
