Key legal question
Whether the taxpayers' cash book was kept in a manner giving it evidentiary value for 2001 tax assessment.
Extracted holding
No. Bare receipts and expenses had to be recorded continuously, completely, and contemporaneously; weekly or bundled entries were insufficient.
Extracted reasoning
For bookkeeping and record-keeping duties, entries must be made close in time to the business event. In cash-intensive businesses the cash book is essential; delayed posting undermines its objective reliability.
