Issues Involved:
1. Interpretation of Section 115J and its impact on carry forward of unabsorbed investment allowance.
2. Prima facie adjustments under Section 143(1)(a) and their validity.
3. Rectification under Section 154 and its scope.
4. Disallowance of investment allowance for the assessment year 1982-83.
5. Disallowance of investment allowance for the assessment year 1989-90.

Detailed Analysis:

1. Interpretation of Section 115J and its Impact on Carry Forward of Unabsorbed Investment Allowance:
The main issue revolves around the interpretation of Section 115J of the Income-tax Act, particularly its sub-section (2) and how it affects the carry forward of unabsorbed investment allowance. The assessee declared income under Section 115J, which was 30% of the book profits. The Assessing Officer (AO) argued that the unabsorbed investment allowance should be deemed to have been allowed to the extent of the available income, reducing the carry forward amount significantly. The Tribunal noted that there were multiple interpretations of Section 115J, supported by opinions from eminent jurists, indicating that the issue was debatable. Consequently, the Tribunal held that the addition of Rs. 1,67,85,300 made by the AO was beyond the scope of prima facie adjustments and rectification under Section 154, and hence, invalid.

2. Prima Facie Adjustments under Section 143(1)(a) and Their Validity:
The Tribunal emphasized that prima facie adjustments under Section 143(1)(a) are limited to obvious and patent mistakes. The adjustments should be apparent from the return of income or accompanying documents. The Tribunal found that the AO's adjustments for the assessment years 1990-91 and 1991-92, particularly concerning the interpretation of Section 115J, involved debatable points of law and were thus beyond the permissible scope of prima facie adjustments.

3. Rectification under Section 154 and Its Scope:
The Tribunal clarified that Section 154 allows for rectification of mistakes apparent from the record, similar to the scope of prima facie adjustments under Section 143(1)(a). However, the Tribunal reiterated that debatable issues are outside the scope of rectification under Section 154. The Tribunal directed that the orders under Section 154 for both assessment years be modified in light of this interpretation.

4. Disallowance of Investment Allowance for the Assessment Year 1982-83:
The AO disallowed Rs. 54,67,510 of investment allowance claimed for the assessment year 1982-83, which had already been absorbed in earlier years as per orders under Section 154. The Tribunal upheld this disallowance, stating that the AO could refer to past records to verify the correctness of carry forward claims. The Tribunal found that the assessee's claim was an apparent mistake, justifying the rectification under Section 154.

5. Disallowance of Investment Allowance for the Assessment Year 1989-90:
The AO disallowed Rs. 16,01,115 of investment allowance for the assessment year 1989-90 based on a Supreme Court judgment delivered after the return was filed. The Tribunal held that the claim made by the assessee was in line with the prevailing Gujarat High Court judgment at the time of filing and could not be considered an apparent mistake. Thus, the Tribunal directed the cancellation of this addition.

Conclusion:
The Tribunal partly allowed the appeals, directing modifications to the orders under Section 154 for the assessment years 1990-91 and 1991-92. The key takeaway is that debatable issues cannot be addressed through prima facie adjustments or rectification under Sections 143(1)(a) and 154. The Tribunal upheld the disallowance of the investment allowance for the assessment year 1982-83 but canceled the disallowance for the assessment year 1989-90.
