Kernrechtsfrage
Whether cantonal court vacation periods suspend the deadline for direct federal tax appeals.
Extrahierter Entscheid
No. The 30-day deadline for direct federal tax appeals is exhaustively governed by federal law, which does not provide for court vacations.
Extrahierte Begründung
Art. 140 and 145 DBG, read together with Art. 133 DBG, contain a complete rule on deadline computation and restoration; there is no room for cantonal deadline suspension rules.
