Key legal question
Whether the 1995-1998 cantonal tax debts were extinguished, prescribed, or protected by good faith based on the 2006 final statements.
Extracted holding
No. The 2006 complementary final statements did not replace earlier assessments, prescription had not expired, and no binding assurance by the authority was shown.
Extracted reasoning
The statements were expressly supplementary; the prescription period ran only from the 2005 final judgment and had not expired; correspondence and later detailed accountings showed no state assurance that earlier debts were cancelled.
