Questão jurídica principal
Whether the administrative law appeal was admissible without a cantonal final decision.
Decisão extraída
The appeal was not admissible because the canton had not yet opened a final cantonal instance for direct federal tax cases.
Fundamentação extraída
Following the court's prior judgment of 19 December 2003, cantons that provide a further cantonal review instance for harmonized cantonal taxes must, from tax year 2001 onward, also open the same instance path for direct federal tax; otherwise the Federal Supreme Court cannot hear the case as last instance.
