Questão jurídica principal
Whether the cantonal court arbitrarily interpreted the municipal sewer regulation by using a 0.45 utilization ratio.
Decisão extraída
No arbitrariness was shown; the challenged interpretation was at least defensible and therefore could not breach Article 9 of the Constitution.
Fundamentação extraída
The municipality itself acknowledged that Article 24 of its regulation could be read as the lower court did. Even if another reading were preferable, the decision would merely be incorrect, not manifestly untenable.
