Questione giuridica chiave
Whether the forced merger decree violated municipal autonomy and cantonal constitutional guarantees.
Decisione estratta
The merger did not violate municipal autonomy or the Ticino constitutional rules on municipal fusion; the canton may order a compulsory merger under the constitution and statute.
Motivazione estratta
Art. 50 Federal Constitution and Ticino constitutional provisions do not bar compulsory mergers. The cantonal constitution expressly allows the Grand Council to decide a merger under statutory conditions, and the challenged decree fell within that framework.
