Kernrechtsfrage
Whether the refusal to hear witnesses and order a counter-expertise violated the right to be heard or arbitrariness protection.
Extrahierter Entscheid
No. The cantonal authority made an admissible anticipatory assessment of the evidence; the appellant did not show an unconstitutional refusal of evidence or arbitrary reasoning.
Extrahierte Begründung
The existing expert report was deemed complete, coherent, and sufficient. The proposed evidence was unclear, partly irrelevant, or incapable of changing the result. The constitutional complaint did not meet the strict substantiation requirements.
