Key legal question
Whether § 26 lit. b of the Zurich signposting ordinance, delegating road-advertising permit authority to municipalities, violates federal law and Art. 49 BV.
Extracted holding
No. Federal law leaves cantons freedom to designate the competent permit authority, including municipal bodies.
Extracted reasoning
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.
