Kernrechtsfrage
Whether the complaint alleging unequal treatment and unfair proceedings before the Federal Administrative Court was well founded.
Extrahierter Entscheid
The procedure remained fair; the appellant was not disadvantaged because it could reply to the BAZL submissions and the authority's late filing did not create unfairness.
Extrahierte Begründung
Article 29(1) BV guarantees fairness in the individual procedure, and expert authority submissions are relevant to factual clarification. The conduct was regrettable but not decisive for fairness.
