Key legal question
Whether the Tribunal could depart from the cantonally established facts on share value and guarantee structure.
Extracted holding
No. The court was bound by the cantonal findings absent a proven procedural exception; the challenge to the factual findings was inadmissible.
Extracted reasoning
The appellants did not invoke any admissible exception allowing departure from the factual findings, and the value issue had already been finally decided in an earlier Federal Supreme Court judgment.
