Key legal question
Whether the complaint met the admissibility and substantiation requirements, including hearing and fact-finding objections.
Extracted holding
The complaint was admissible in principle, but the objections to the refusal of an on-site inspection and to the factual findings were insufficiently substantiated and failed on the merits.
Extracted reasoning
The Federal Supreme Court held that the appellant did not show arbitrariness or a decisive denial of the right to be heard; several factual assertions were unsupported or irrelevant to the outcome.
