Questão jurídica principal
Whether the tax authority was entitled to assess turnover by estimation because the bookkeeping was unreliable.
Decisão extraída
Yes. The accounting lacked essential records and did not permit reliable tracing of cash movements, so estimated assessment was justified.
Fundamentação extraída
Incomplete books and missing daily revenue records made the accounts non-probative; the taxpayer did not show that the estimate was manifestly wrong.
