Social security court decision establishing farmer's insurance status cannot have retroactive effect due to administrative error.

The Supreme Court reversed the appellate court's decision regarding a farmer's spouse's social security status, ruling that the administrative body made a clear error in choosing between insurance types. The court held that while the erroneous decision could be corrected, it could not retroactively negate the insurance coverage that had already begun. This ruling prioritized the principle of legal certainty and the protection of citizens' trust in state organs over the administrative mistake.
