Kernrechtsfrage
Whether the appeal against the Federal Administrative Court's refusal of night-work authorization is admissible and the challenged factual findings may be reviewed.
Extrahierter Entscheid
The appeal was admissible in principle, but new evidence submitted for the first time before the Federal Supreme Court was disregarded, and the factual findings were upheld.
Extrahierte Begründung
Review is limited by Art. 105 and 99 BGG; only facts established below count unless the lower judgment gives rise to new evidence. The appellants' new survey could and should have been filed earlier.
