Kernrechtsfrage
Whether the loss from one property sale could be deducted from property gains realized in the same calendar year under Obwalden law.
Extrahierter Entscheid
For the applicable old law, gains and losses from several real-estate sales in the same calendar year had to be taken into account consistently; limiting the loss to rate determination only was arbitrary and inconsistent with ability-to-pay.
Extrahierte Begründung
Art. 155(2) a.F. StG/OW grouped multiple gains for rate purposes, but excluding losses from the tax base while aggregating gains created random and unjust results. The former rule had to be read in line with economic ability to pay.
