Kernrechtsfrage
Whether the original applicants were entitled to appeal to the Verwaltungsgericht despite not having been parties in the departmental complaint proceedings.
Extrahierter Entscheid
Yes. Persons who initiated the first-instance request for traffic measures have standing to appeal the later decision annulling those measures, even if they were not admitted to the departmental proceedings.
Extrahierte Begründung
The applicants had a legally relevant interest in the traffic arrangement affecting access and use of the road. The lack of participation below did not bar appeal because they were wrongly denied participation; standing is not limited to persons already heard by the reviewing authority.
