Questão jurídica principal
Whether the wife's joint liability for the spouses' cantonal and communal tax debts violates equality and marriage rights.
Decisão extraída
No. Spousal tax solidarity is a permissible collection mechanism and does not breach equality or the right to marry.
Fundamentação extraída
Married spouses are treated as an economic unit in tax law and in general marital rules; different treatment from concubins is justified. The fact that Vaud did not mitigate solidarity upon one spouse's insolvency does not make the rule arbitrary.
