Question juridique clé
Whether the cantonal smoking ban could be challenged by abstract norm control and whether the appellant had standing, including as regards water pipes.
Solution extraite
The complaint was admissible against the cantonal statute, and the appellant was sufficiently affected because shisha smoking falls within the smoking ban.
Motifs extraits
Direct review of cantonal enactments is available under the BGG. The bar operator was actually affected, since shisha is tobacco smoking and the law covers it.
