Question juridique clé
Whether the amended Aargau tax law's low-income deduction violates equality under Art. 8 BV.
Solution extraite
The complaint did not establish a constitutional violation; the cantonal legislature had room to grant tax relief for modest incomes, and the attack on the system was insufficiently substantiated.
Motifs extraits
The court held that the deduction could be viewed as tax relief for modest incomes rather than a social deduction. The complainant failed to show that the tariff, considered with the deduction, was unconstitutional or that the overall tax burden across income levels disregarded economic capacity. The complaint also did not satisfy the substantiation requirements.
