Key legal question
Whether the federal appeal against the cantonal non-entry decision was sufficiently reasoned under Art. 42 BGG.
Extracted holding
The appeal did not address the decisive procedural reasoning and therefore lacked an adequate legal substantiation.
Extracted reasoning
The appellant argued only about the merits of the tax fine and made no substantive showing of how the cantonal court allegedly violated federal law in applying cantonal procedural rules on cost advances and non-entry.
