The effect of s. 80-IA(9) is that s. 80-IA deduction has to be reduced for s. 80HHC deduction in all cases and not only when the combined deduction exceeds the profits

CIT vs. M/s Atul Intermediates (Gujarat High Court)

Sub-section (9) of s. 80IA is aimed at restricting the successive claims of deduction of the same profit or gain under different provisions contained in sub-chapter C of Chapter VI of the Act. This provision, therefore, necessarily impacts other deduction provisions including s. 80HHC of the Act. Nothing contained in s. 80HHC suggests that the deduction provided therein was immune from any outside influence or that the provision was impregnable by any other statute or enactment. Accepting any such theory would lead to incongruous results. Even the assessee concedes that sub-section (9) of s. 80IA would operate as to limiting the combined deductions to a maximum of the profits and gains from an eligible business of the undertaking or enterprise. If s. 80HHC contained a protective shell making it immune from any outside influence, even this effect of sub-section (9) of s. 80IA could not be applied. This would completely render the provisions of sub-section (9) of s. 80IA redundant and meaningless.
