Kernrechtsfrage
Whether the 1994 declaratory decision could be declared null because it allegedly misclassified the farm and ignored leased land.
Extrahierter Entscheid
The defects alleged were not serious, obvious, and exceptional enough to justify nullity; at most the decision was appealable, not void.
Extrahierte Begründung
Nullity of administrative acts is exceptional. Errors in factual assessment, legal application, or discretion normally do not nullify a decision, especially where legal certainty prevails. The disputed classification was at most a difficult borderline assessment.
