Shri
I stand still to the views given before. Making an effort that in erstwhile Act, the Cess and Surcharge were levied on aggregate basis while in Comp.Cess Act it is levied as Ad valorem. This makes lots of difference from my point of view. As an example, in GST decision is passed by high court that if principal supply i.e. Electricity is exempted all other supply forming composite supply will be exempted. while this is not applicable to mixed supply.
In other words in erstwhile Act cess and surcharge were levied on the duty/tax, so if duty/tax is exempted levy of cess or surcharge is not applicable means Cess were depending upon duty/tax. While here it is the case of ad valorem means it is not dependent of duty/tax.
Shri Kasturiji Sir, with due respect, we lay foundation for querist, now it upto him/her to take decision as per their wisdom.
With Due Regards
