Questione giuridica chiave
Whether the public-law appeal against the cantonal general ordinance was admissible.
Decisione estratta
The appeal was formally admissible as a challenge to a general normative act, filed in time and directly before the federal court because no cantonal abstract-norm review existed.
Motivazione estratta
The ordinance was a general measure under Art. 84 OJ; the 30-day deadline was met; exhaustion of cantonal remedies was not required because Neuchâtel provided no abstract review procedure.
