Questão jurídica principal
Whether the public-law agreement remained in force beyond 2006 and required continued tax-loss compensation
Decisão extraída
The agreement continued to apply after 2006; the compensation obligation remained in force for later stages of the landfill.
Fundamentação extraída
The cantonal court's finding of a concordant actual will regarding duration was binding absent manifest error; alternatively, even under trust-based interpretation, the decision was not arbitrary.
