CIT vs. Sati Oil Udyog Ltd (Supreme Court)

The object of Section 143 (1A) is the prevention of tax evasion. Read literally, both honest asessees and tax evaders are caught within its net.

Section 143 (1A) can only be invoked where it is found on facts that the lesser amount stated in the return filed by the assessee is a result of an attempt to evade tax lawfully payable by the assessee. The burden of proving that the assessee has so attempted to evade tax is on the revenue
