Kernrechtsfrage
Whether the interim assessment effective 1 January 1997 was arbitrary because the tax authority allegedly already knew of the cohabitation when the 1997/98 assessment became final.
Extrahierter Entscheid
No. The record did not show that the authority knew of the cohabitation merely because the maintenance contract was internally forwarded within the tax administration.
Extrahierte Begründung
The appellant's inference from internal transmission of a document only proved awareness of the wife's move, not knowledge of cohabitation of mother and child. The cantonal court's factual assessment was therefore not manifestly erroneous.
