Retrospective application of tax laws upheld for pending assessments in partially excluded areas under constitutional legislative power.

The Income-tax Act, 1922 was already in force in the partially excluded areas of Chotanagpur and Santal Parganas, so lack of an earlier specific notification did not defeat its application. Section 92 of the Government of India Act, 1935 was treated as conferring legislative power on the Governor to apply laws with exceptions, modifications and retrospective effect, including regulations for peace and good government. Notices issued before the Governor's notification did not deprive the Income-tax Officer of jurisdiction, because notice and return provisions were only assessment machinery. The retrospective notification and validating regulation validly applied the taxing enactments to pending proceedings, and the assessments were upheld.

Issues: (i) whether the Indian Income-tax Act, 1922 continued to operate in the partially excluded areas of Chotanagpur and Santal Parganas without a prior notification or regulation specifically applying it; (ii) whether Section 92 of the Government of India Act, 1935 conferred legislative power on the Governor to issue notifications and regulations with exceptions, modifications, and retrospective effect; (iii) whether notices issued under Section 22 of the Indian Income-tax Act, 1922 before the Governor's notification deprived the Income-tax Officer of jurisdiction to complete the assessment; and (iv) whether the Governor's notification and validating regulation could validly apply the taxing enactments retrospectively to pending assessment proceedings.

Issue (i): whether the Indian Income-tax Act, 1922 continued to operate in the partially excluded areas of Chotanagpur and Santal Parganas without a prior notification or regulation specifically applying it.

Analysis: The Act extended to the whole of British India and, by the constitutional continuity provision, continued in force in Bihar unless altered by competent authority. The partially excluded character of the area did not mean that the parent Income-tax Act was absent altogether. The later notification and regulation were therefore concerned with the application and timing of amendments and ancillary fiscal enactments, not with creating the very existence of the charging law in the area.

Conclusion: The Act was already in force in the area, so this objection failed.

Issue (ii): whether Section 92 of the Government of India Act, 1935 conferred legislative power on the Governor to issue notifications and regulations with exceptions, modifications, and retrospective effect.

Analysis: The power to direct application of an Act with exceptions or modifications was treated as legislative in character because the Governor could alter the operation of statutory provisions in the area. The regulation-making power under Section 92(2) was wider still and authorised regulations for peace and good government, including repeal or amendment of existing laws applicable to the area. Read together, the provisions vested plenary legislative authority for the subject-matter in the Governor when acting under the respective sub-sections.

Conclusion: Section 92 conferred legislative power, including power to make the relevant enactments applicable with retrospective effect.

Issue (iii): whether notices issued under Section 22 of the Indian Income-tax Act, 1922 before the Governor's notification deprived the Income-tax Officer of jurisdiction to complete the assessment.

Analysis: The liability to tax arises from the charging provisions, while notice and return provisions are machinery provisions for assessment and quantification. The validity of the assessment does not depend on the prior validity of the notice as a foundation of liability or jurisdiction. Even if the notices preceded the notification, the assessment proceedings were still pending when the applicable law was extended, so the machinery could operate on the law then in force.

Conclusion: The prior notices did not invalidate the assessments or deprive the officer of jurisdiction.

Issue (iv): whether the Governor's notification and validating regulation could validly apply the taxing enactments retrospectively to pending assessment proceedings.

Analysis: The notification expressly declared that the specified Acts should be deemed to have been applied retrospectively from the dates on which they came into force in other parts of Bihar. The regulation, enacted under Section 92(2), was designed to remove doubts and likewise used deemed retrospective language. Because the assessment and appellate proceedings were still pending when the retrospective measures took effect, the assessments were governed by the extended law and remained valid.

Conclusion: The retrospective application was valid and cured any doubt about the assessments.

Final Conclusion: The challenge to the validity of the tax assessments failed on all substantial grounds, and the assessments were upheld.

Ratio Decidendi: In taxing statutes, liability flows from the charging provisions and assessment provisions are only machinery; and where a constitutional authority is empowered to apply or amend laws for a special area, that power includes retrospective application to pending proceedings if the legislation so provides.
