Kernrechtsfrage
Whether the debt-lifting decision was validly served so that the debtor had to expect it.
Extrahierter Entscheid
The debtor did not have to expect service; the decision was not shown to have reached him, and no procedural relationship arose.
Extrahierte Begründung
After the payment order and objection, the debtor need not anticipate a later lifting decision. The insurer failed to show receipt of the later notice and warning letter, so neither the postal fiction nor Art. 38(2bis) ATSG helped.
