Questão jurídica principal
Whether the appellant's right to be heard was violated by an inspection conducted without inviting him.
Decisão extraída
Yes. The inspection was a probative measure by the deciding authority's case handler, so the parties had to be invited.
Fundamentação extraída
The commission president acted as a functional part of the deciding authority and relied on the inspection in the decision. In a contentious traffic-measure procedure, evidentiary inspections must as a rule be carried out with the participation of the parties; the ex parte participation of the city representative further infringed equality of arms.
