Kernrechtsfrage
Whether the constitutional challenge was timely despite being filed before promulgation after the optional referendum period.
Extrahierter Entscheid
Premature filing did not bar admissibility; the case could be heard, although such filings usually only justify suspension.
Extrahierte Begründung
For referendable cantonal statutes, the federal deadline runs from promulgation, not from initial publication. An early appeal is not inadmissible as such.
