Kernrechtsfrage
Whether the company’s appeal on direct federal tax was time-barred because cantonal holiday suspensions did not apply.
Extrahierter Entscheid
The appeal on direct federal tax was late; the cantonal suspension of deadlines during judicial holidays did not apply to federal direct tax proceedings.
Extrahierte Begründung
Article 133 LIFD exhaustively regulates time limits and does not provide for holiday suspension. Harmonization concerns do not justify importing cantonal holiday rules into IFD proceedings absent a specific cantonal rule; counsel should have known the applicable federal deadline rules.
