Question juridique clé
Whether the amended tax-adjustment rule violated Neuchâtel Constitution Art. 57(3) by allowing a simple majority to block full compensation of cold progression.
Solution extraite
No. Article 57(3) covers positive legislative acts that increase or decrease tax revenue; it does not require a qualified majority for parliamentary inaction on inflation-driven revenue changes.
Motifs extraits
The constitutional provision targets laws and decrees as active legislative measures. Failing to adjust for inflation is not itself within its scope, and requiring a three-fifths majority for non-action would create democratic blockages.
