“reasons recorded”

The validity of reassessment proceedings initiated under Section 147, by issuing a notice under Section 148, must be judged solely on the reasons originally recorded by the Assessing Officer. These recorded reasons cannot be supplemented, improved upon, or modified at any later stage.

A mistake apparent from the record under Section 154 must be an obvious and patent error, not one that requires a long and elaborate process of reasoning or where two opinions are conceivable. Rectification under Section 154 is not permissible for re-examining issues already considered or requiring detailed re-computation.

Reassessment of income, especially after a summary assessment under Section 143(1), requires the Assessing Officer to possess fresh, tangible material to form a reason to believe that income has escaped assessment; a mere reappraisal of existing records or a change of opinion without new material is not permissible.

Reassessment proceedings are invalid if initiated based on documents already available on record without fresh tangible material, and if the sanction under section 151 is accorded mechanically, indicating non-application of mind.

The requirement of statutory prior approval by a high-ranking authority, even if administrative, serves as an in-built protection against arbitrary exercise of power by the Assessing Officer. While such approval need not record elaborate reasoning, the approving authority has a heavy duty to ensure it is not an empty ritual, fulfilling its purpose of supervisory control.

Reassessment proceedings are invalid if the reasons recorded for initiating action under section 148 are not served on the assessee within the limitation period prescribed by section 149. Furthermore, reassessment cannot be based on a mere change of opinion without tangible material, particularly when the assessee has made a full and true disclosure of material facts.

For assessments under Section 153C, a specific satisfaction note by the Assessing Officer of the person searched, recorded prior to initiating proceedings, is a jurisdictional prerequisite, rendering its absence void. The approval function under Section 153D is administrative and does not require elaborate reasoning.

Reassessment proceedings under Section 147 are invalid if the Assessing Officer records satisfaction based on borrowed satisfaction or information without independently applying their mind and forming their own 'reason to believe' that income has escaped assessment. The AO must arrive at an independent conclusion, not merely act on a report from an investigation wing without due diligence.
