Question juridique clé
Whether the omission of an express creditor designation in the tax assessment justified refusal of definitive debt enforcement.
Solution extraite
The omission did not justify refusal, because the creditor identity was sufficiently clear from the assessment and the debtor could not be left in doubt.
Motifs extraits
Formal requirements for party designation in enforcement proceedings must not be overstretched; decisive is whether the debtor is uncertain about the creditor's identity. A cantonal tax office issuing an assessment for the direct federal tax acts for the Canton, not for itself, and no real doubt about the creditor existed.
