“change of opinion”

An Assessing Officer cannot initiate reassessment proceedings under Section 147 of the Income Tax Act based on a mere change of opinion. Reassessment is permissible only when there is fresh tangible material leading to the belief of income escapement, not merely a review of existing facts.

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.

An Assessing Officer cannot reopen an assessment under Section 147 based on a mere change of opinion regarding the same material available during the original assessment. Reopening requires fresh, tangible material or information that leads to a reason to believe income has escaped assessment.

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 initiated under Section 147 beyond four years from the end of the relevant assessment year are invalid unless the assessee failed to disclose fully and truly all material facts necessary for assessment. Without such failure, the notice issued under Section 148 is time-barred and without jurisdiction.

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.

Reassessment proceedings under Section 147 are invalid and void ab initio if initiated based on 'borrowed satisfaction' without the Assessing Officer's independent application of mind, or merely on documents already available on record without fresh tangible material.
