Questione giuridica chiave
Whether § 26 lit. b of the Zurich signposting ordinance, delegating road-advertising permit authority to municipalities, violates federal law and Art. 49 BV.
Decisione estratta
No. Federal law leaves cantons freedom to designate the competent permit authority, including municipal bodies.
Motivazione estratta
Art. 106 SVG and Art. 100 SSV require cantonal designation of the competent authority but do not reserve the task to cantonal authorities only. Art. 96(8) SSV is a special rule for certain exceptions and does not imply a general prohibition on municipal competence for ordinary, federally compliant road advertisements.
