Kernrechtsfrage
Whether the canton had standing under Art. 89(1) BGG to challenge the cantonal court's tax judgment.
Extrahierter Entscheid
The canton was not specially and qualitatively affected in its sovereign interests and therefore lacked standing.
Extrahierte Begründung
The abolished inheritance tax for descendants was no longer a significant regulatory field for the canton; a general interest in correct law application and financial interests were insufficient.
