Questione giuridica chiave
Whether the cantonal tax claim was time-barred
Decisione estratta
The prescription was validly interrupted by the cantonal tax authority's letter of 14 September 2000.
Motivazione estratta
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.
