Question juridique clé
Whether the spouses' joint liability for state tax was extinguished by claimed insolvency or separation
Solution extraite
The spouses failed to prove the husband's insolvency, so joint liability for state tax in the relevant years remained unchanged.
Motifs extraits
Insolvency must be shown by the applicants. Existing debts alone did not prove lasting inability to pay, especially given indications of undisclosed income and asset transfers benefiting the wife.
