MAT on statutory corporations depends on company-status preconditions; debatable liability cannot be introduced through rectification.

Section 154 cannot be used to introduce a disputed MAT liability against a statutory corporation where applicability of section 115JB is debatable and requires detailed reasoning beyond patent rectification. The Tribunal noted that a corporation created under a special enactment is not a company under the Companies Act framework, so the book-profit mechanism does not operate unless the statutory preconditions for company-based computation are satisfied. For assessment year 2013-14, the post-amendment position did not change that result, and MAT remained inapplicable to the assessee.

Issues: (i) Whether the applicability of section 115JB to the assessee, a statutory corporation established under a special enactment, could be brought to tax through rectification under section 154; (ii) Whether the post-amendment position for assessment year 2013-14 altered the non-applicability of MAT to such a statutory corporation.

Issue (i): Whether the applicability of section 115JB to the assessee, a statutory corporation established under a special enactment, could be brought to tax through rectification under section 154.

Analysis: The assessee was held to be a statutory body created under its governing enactment and not a company incorporated under the Companies Act. The controversy whether MAT could be imposed on such an entity required examination of the statutory status of the assessee, the nature of its accounts, and the scope of section 115JB, all of which showed that the issue was not free from doubt. The attempted invocation of section 154 would have required a long-drawn reasoning process and not the correction of an obvious and patent mistake. The rectification jurisdiction could not be used to effect a substantive change of opinion or to travel beyond the scope of the original assessment or giving-effect order.

Conclusion: The use of section 154 to apply MAT was not permissible, and the rectification orders for the earlier years were invalid.

Issue (ii): Whether the post-amendment position for assessment year 2013-14 altered the non-applicability of MAT to such a statutory corporation.

Analysis: The amendment to section 115JB from assessment year 2013-14 was considered, but the assessee remained a statutory corporation created under a special law and not a company in the sense required for MAT computation. The Tribunal applied the later judicial understanding that the deeming provisions in the Income-tax Act did not by themselves extend MAT to entities whose accounts were not prepared under the Companies Act framework. The book-profit machinery could not operate where the foundational requirement of company status under the relevant corporate accounting regime was absent.

Conclusion: MAT was held not leviable even after the post-amendment regime, and the assessee's appeal for assessment year 2013-14 was allowed.

Final Conclusion: The rectification-based MAT additions were set aside for the relevant years, the Revenue's appeals were dismissed, and the assessee succeeded for assessment year 2013-14 on the substantive MAT issue.

Ratio Decidendi: Section 154 cannot be used to introduce or alter a disputed MAT liability where the issue is debatable, and section 115JB applies only where the statutory preconditions for company-based book-profit computation are satisfied.
