Key legal question
Whether the appeal could challenge the expropriation decision and the requested plan changes.
Extracted holding
The appeal was admissible only to the extent that the appellants concretely showed a federal-law violation affecting their properties; general criticism of the project was inadmissible.
Extracted reasoning
In expropriation objection proceedings, all objections against the expropriation and plan-change requests may be raised, but private affected parties may not attack the project in general; municipalities may invoke only neighboring-rights protection under Art. 7(3) EntG.
