Key legal question
Whether the Federal Supreme Court could review the defendant's challenges to the factual findings on quantity sold and profit margin
Extracted holding
The challenges were largely inadmissible because they attacked evidence assessment and factual findings, which are binding on appeal absent a proper federal-law exception.
Extracted reasoning
Lost profit, its amount, and natural causation are matters of fact. The appellant mostly contested the lower court's appraisal of evidence and failed to show a cognizable violation of federal law or a proper basis for factual supplementation.
