Question juridique clé
Whether a quality assurance system for mobile antennas needs a formal legal basis beyond the NISV and BAFU circular.
Solution extraite
No additional statute or ordinance was required; the BAFU circular was a permissible implementation recommendation and the system remained within the framework of the NISV.
Motifs extraits
The system only controls compliance with already authorized parameters; Art. 12 NISV provides for control, while Arts. 36, 38 and 41 USG support BAFU supervision and coordination. The circular does not create new binding rules.
