Question juridique clé
Whether Basel-Stadt's stricter smoking ban in § 34 GGG/BS was precluded by federal law and federal competence rules
Solution extraite
The cantonal rule was not contrary to federal law or the constitutional competence order.
Motifs extraits
Art. 4 PaRG leaves room for stricter cantonal health rules; the cantonal measure pursues both health protection and prevention of smoking, and in restaurants the protection of guests and staff cannot be clearly separated.
