Section 133A enables the income-tax authority only to record any statement of any person which may be useful but does not authorize for taking any sworn in statement - Paul Mathews & Sons v. CIT [2003] 129 Taxman 416 (Ker.).
Section 133A does not empower any ITO to examine any person on oath. In contradistinction to the power under section 133A, section 132(4) enables the authorized officer to examine a person on oath and any statement made by such person during such examination can also be used in evidence under the Income-tax Act. On the other hand, whatever statement is recorded under section 133A is not given an evidentiary value. The statement obtained under section 133A would not automatically bind upon the assessee. Therefore, admission made during such statement cannot be made the basis of any admission - CIT v. S. Khader Khan Son [2008] 300 ITR 157 (Mad.).
