Key legal question
Whether the conviction for negligent violation of the Planning and Building Act was arbitrary because the excess built area was below 1% and thus not punishable.
Extracted holding
A negligible excess of less than 1% in approved building volume could not, on these facts, constitute a legally relevant violation; the conviction was untenable.
Extracted reasoning
System-related measurement and implementation tolerances in building projects must be accepted. The cantonal administrative court’s 1% tolerance for minor deviations was deemed reasonable, and the lower court’s distinction between measurement inaccuracies and omitted room areas was unconvincing given the tiny overages at issue.
