Questione giuridica chiave
Whether the administrative law appeal against the refusal to recuse the commission president was admissible only on the recusal question.
Decisione estratta
The appeal could address only the recusal issue; the requested declaration on the scope of expropriation and the provisional payment request were inadmissible.
Motivazione estratta
A decision on recusal by a federal expropriation commission is appealable, but the review is confined to that question and does not extend to other issues in the pending expropriation proceedings.
