Kernrechtsfrage
Whether connection fees under the Solothurn building and fee regulations are subject to limitation periods.
Extrahierter Entscheid
Yes. Although the BauG, KER and the municipal regulation contain no express prescription rule, public-law claims lapse by the passage of time as an unwritten principle. For one-time connection fees, the court applied a 10-year assessment limitation by analogy to cantonal rules for one-time taxes and to general civil-law prescription principles.
Extrahierte Begründung
The court first noted the absence of an express limitation provision. It then relied on the recognized unwritten principle that public-law claims extinguish over time. For the start and length of the period, it looked primarily to analogous public-law rules, and failing that to general civil-law principles. Because connection fees are one-off causal charges comparable to one-time taxes rather than recurring taxes, the 10-year assessment limitation was the most fitting analogy.
