Questão jurídica principal
Whether input tax deduction had to be reduced because the aircraft purchases and services were used mainly for the shareholder's private purposes rather than taxable output transactions.
Decisão extraída
Yes. The disputed inputs did not flow into taxable outputs but served the shareholder's private needs, so the input tax deduction had to be reduced.
Fundamentação extraída
The factual findings showed a hidden purpose and primarily private use; occasional third-party revenues did not change the dominant private character of the company’s activity.
