Question juridique clé
Whether the imputed rent assessment for the appellant's self-occupied house was arbitrary under Art. 9 BV.
Solution extraite
No arbitrariness was shown; the assessment followed the cantonal rules and a 10% discount below market rent was not constitutionally required.
Motifs extraits
The appellant did not sufficiently substantiate unequal treatment. The cantonal regulation differentiated between regions. The prior assessed amount was already the taxable imputed rent, so no further 10% deduction had to be made. No fixed percentage follows from the cantonal constitutional rule on owner-occupied housing.
