Question juridique clé
Whether the appellants had standing to challenge the Meldeauflage provisions
Solution extraite
Thommen lacked even virtual interest as the measure could only be ordered by the canton of residence, so the complaint was inadmissible in that respect.
Motifs extraits
The Zurich ordinance did not apply to him for Meldeauflage, because only the residence canton is competent under BWIS.
