Questão jurídica principal
Whether the alleged underpriced sale and hidden profit distribution were sufficiently established for direct federal tax purposes.
Decisão extraída
The factual basis was insufficient; the case had to be sent back for further fact-finding, including valuation evidence and clarification of the parties' shareholding relations.
Fundamentação extraída
An underprice below construction cost does not by itself prove market-value undervaluation. The authorities had not proven the decisive discrepancy or the prerequisites for applying the triangle theory, and the factual record was incomplete.
