Kernrechtsfrage
Whether the appeal could be treated as a direct abstract constitutional review of Art. 155(1) StG/SH.
Extrahierter Entscheid
No; the deadline for abstract review of the cantonal norm had long expired, so the norm could only be reviewed incidentally in a concrete case.
Extrahierte Begründung
Direct challenge to a cantonal enactment must be filed within the statutory time limit after publication under Art. 101 BGG; that period had expired.
