SHEO NATH SINGH vs APPELLATE ASSISTANT COMMISSIONER OFINCOME TAX, CALCUTTA

The Supreme Court held that under Section 34(1-A) of the Income-tax Act, 1922, the 'reason to believe' must stem from an honest and reasonable belief based on substantial grounds, not mere suspicion. The Court ruled that the High Court erred in sustaining a preliminary objection while also deciding on the validity of the notice, emphasizing that the Income-tax Officer's jurisdiction hinges on the existence of valid reasons for belief. The appeal was allowed, affirming the need for a proper basis for the Income-tax Officer's actions.
