Kernrechtsfrage
Whether the right to be heard was violated by non-disclosure of a witness statement and, if so, whether the defect was cured on appeal.
Extrahierter Entscheid
Any procedural defect was cured in the administrative appeal because the applicant learned the essential content of the withheld statement, could comment on it, and the reviewing authority had full cognizance without causing prejudice.
Extrahierte Begründung
A cure is exceptional, but is possible when the higher authority has the same scope of review, the party can fully exercise its rights afterwards, and the violation is not serious. Those conditions were met here.
