Key legal question
Whether the federal tax appeal met the motivation requirements of Art. 42 LTF
Extracted holding
The appeal did not sufficiently engage with the cantonal court's reasoning and therefore lacked topically directed motivation.
Extracted reasoning
The appellant merely repeated arguments already raised below, without showing why the canton court's analysis on retroactive disability pensions, set-off against social benefits, and the privileged tax rate violated federal or cantonal law.
