Question juridique clé
Whether cantonal court vacation periods suspend the deadline for direct federal tax appeals.
Solution extraite
No. The 30-day deadline for direct federal tax appeals is exhaustively governed by federal law, which does not provide for court vacations.
Motifs extraits
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.
