Kernrechtsfrage
Whether the refusal of full access to the file violated the appellant's right to be heard under the Administrative Procedure Act.
Extrahierter Entscheid
The complaint failed because the confidential information was not decisive; the essential content had been communicated and the appellant could comment and offer counter-evidence.
Extrahierte Begründung
Under Arts. 26-28 PA, access may be restricted for important private interests, but use of withheld material is permissible if its essential content is disclosed. Since the challenged information was not essential to the outcome, any defect was immaterial.
