Questione giuridica chiave
Whether the subsidiary constitutional complaint against the cantonal inadmissibility judgment was admissible despite the incidental nature of the decision.
Decisione estratta
The complaint was admissible because the applicant could invoke a formal denial of justice and a possible irreparable prejudice from the continued suspension.
Motivazione estratta
Limiting irreparable prejudice to substantive rights would prevent challenges to formal denials of justice; that interpretation of cantonal law was arbitrary where the naturalization procedure risked being delayed indefinitely.
