The Supreme Court case involves Mitsubishi Corporation, a non-resident company claiming it was not liable for advance tax due to TDS not being deducted by the payer for the assessment year 2004-05. The Court ruled that there was no obligation to pay advance tax when tax was not deducted, thus reversing lower court decisions which held otherwise. This ruling clarifies that the amendment brought by the Finance Act 2012 does not apply retroactively to the case at hand.
