Questione giuridica chiave
Whether the cantonal and municipal tax assessments unlawfully treated the married couple more heavily than comparable cohabiting couples.
Decisione estratta
No. The burden differential of about 5.76% to 6.09% remained within the tolerated range and did not show a systematic, constitutionally relevant disadvantage.
Motivazione estratta
Absolute tax equality is not required. A canton must ensure a fair balance across all relevant taxpayer groups; a difference below the usual 10% threshold does not justify judicial correction absent a general, systematic overtaxation of married couples.
