Kernrechtsfrage
Whether the cantonal tax claim was time-barred
Extrahierter Entscheid
The prescription was validly interrupted by the cantonal tax authority's letter of 14 September 2000.
Extrahierte Begründung
Article 78 LMSD must be read in light of the CO rules on interruption; in public tax law, official acts aimed at fixing the tax claim and communicated to the taxpayer can interrupt prescription.
