Assessment years: 1970-71
01 · Facts of the case
These sixteen appeals by special leave challenged a common Gauhati High Court judgment on section 10(26)(a) of the Income-tax Act, 1961. The Court set out the circumstances of the respondent in Civil Appeal No.579 of 1975: he belonged to the Jaintia Scheduled Tribe and was a permanent resident of the United Khasi-Jaintia Hills Autonomous District. He had entered Assam Government service in 1941 and, for the previous year relevant to AY 1970–71, was posted at Shillong as Secretary to that Government. His office in the Assam Secretariat stood within the part of Shillong Municipality outside the relevant Sixth Schedule area (physical pages 2–3/SCR 414 H–415 C).
The Officer regarded his salary as arising in a non-scheduled area and assessed it to tax. The respondent disputed that source conclusion and alternatively challenged the validity of making the exemption depend on the source’s location. His Article 226 petition attacked the assessment and demand notices for AY 1970–71. The High Court held the source distinction artificial and inconsistent with an exemption intended to benefit Scheduled Tribe residents, struck down sub-clause (a) under Article 14, and quashed the notices and assessments (physical pages 3–4/SCR 415 C–416 A).
Tribal status and specified-area residence were admitted. Whether his salary in fact accrued or arose from a qualifying source was left open by the High Court and remained undetermined in the Supreme Court. Thus the common legal question concerned the validity of the source condition, not a final factual denial of this respondent’s salary exemption. The report does not supply separate assessment years or facts for the other fifteen appeals (physical page 6/SCR 418 B–E; physical page 10/SCR 422 E–F).

02 · Discussion by the Hon’ble Court
The Court traced the exemption from the 1922 provision introduced and amended in the 1950s to section 10(26) of the 1961 Act. It explained that S.K. Datta v. Lawrence Singh Ingty had invalidated the exclusion of Government servants and that the 1970 amendment removed that exclusion. This historical discrimination was different from the geographic-source condition now in issue (physical pages 4–5/SCR 416 B–417 B).
The provision as reproduced required Scheduled Tribe status, residence in a specified territory, and income of the qualifying kind. The third requirement contained alternatives: income from a source in the specified territories under sub-clause (a), or dividend/interest-on-securities income under sub-clause (b). The Court’s analysis therefore did not erase the statutory dividend/interest limb. The dispute before it was the validity of sub-clause (a), not a claim under sub-clause (b) (physical page 5/SCR 417 C–H).
The High Court and respondent relied on Lawrence Singh Ingty’s statement that the exemption was given to a class. The Court rejected extracting that statement from its setting. Ingty concerned an unjustified distinction within the selected tribal residents between Government employees and others, such as private employees or professionals. The validity of sub-clause (a) had not even indirectly been questioned there. Ingty did not establish a blanket exemption for every income of every qualifying tribal resident (physical pages 6–8/SCR 418 F–420 A).
A taxing law remains subject to Article 14. But, within legislative competence, the legislature has substantial room to choose taxable persons, districts, property, goods, incomes and objects. A heavier burden on some members of a category does not alone establish invalidity; an unjustifiable unequal operation within the selected range does. Applying that principle, the Court treated classification by source as integral to the 1961 Act’s scheme and illustrated it from residence, agricultural income and other exemptions/deductions. Those illustrations were not independent rulings on claims under those provisions (physical pages 8–9/SCR 420 B–421 E).
The source distinction was intelligible and served the dual aim of benefiting the selected tribal residents and the specified areas economically. The Court also explained that removing it could facilitate sham profit-allocation arrangements and unequal treatment of tribal and non-tribal participants in the same outside business. These were illustrative risks, not findings that this respondent had undertaken such an arrangement. It rejected counsel’s Article 46 argument and recognised legislative responsibility for the extent and conditions of protective fiscal policy (physical pages 9–10/SCR 421 E–422 C).
The Court accordingly upheld sub-clause (a). Counsel’s further contention that the salary’s real source lay within the tribal areas, despite the office’s location, was expressly left undecided. No general rule that the work-site alone determines salary source was declared (physical page 10/SCR 422 D–F).

03 · Judicial decision
The Court reversed the High Court’s judgment, held section 10(26)(a) constitutionally valid and allowed all sixteen departmental appeals. It expressly left the actual source of the respondent’s salary open and undetermined. Each side was to bear its own costs. The final order contains no express remand direction or final adjudication of the disputed source fact (physical page 10/SCR 422 D–F).
Source: See the proposition-specific paragraph and PDF-page references below.
04 · Outcome / in whose favour
In whose favour: Revenue on constitutional validity; factual salary-source entitlement unresolved
Civil Appeals Nos.579–594 of 1975 allowed; High Court judgment reversed; parties to bear their own costs
Geographic-source condition upheld under Article 14; salary-source fact and consequent individual entitlement expressly undecided
No blanket exemption; no holding that this salary necessarily arose outside the specified area; no work-site-only source test; no independent adjudication under the dividend/interest limb.

05 · AKHB REVIEW POINT
Keep the validity of an exemption condition separate from whether a taxpayer satisfies it. Establish tribal status and qualifying residence, identify the applicable historical territorial text, and analyse the income-source issue on its evidence. This decision supplies constitutional reasoning for a geographic-source condition; it does not answer the source issue that the Court expressly reserved.
The separately checked official historical versions show why the applicable year matters: territorial language changed while the source and dividend/interest alternatives remained distinct. The 2011 compilation records later territorial amendments and a 21 January 1972 effective date for the 1974 substitution, differing from the judgment’s printed 25 January date. These bounded comparisons and the later Badiya citation do not establish today’s exemption limits or a complete subsequent-treatment history.

- finding
- Madhukar Balkrishna Badiya (17 August 1988) expressly cites Rymbai for legislative latitude in tax classification subject to Article 14, in a motor-vehicle-tax case. The passages do not decide the salary-source question or the contemporary reach of section 10(26).

- finding
- The separately checked 2011 compilation and official 1977, 1986 and 2016 HTML editions retain the distinction between tribal status, specified residence and qualifying income. Section 10(26)(b) separately covers dividend or interest on securities. The 2011 notes identify the 1970 amendment retrospectively from 1 April 1962 and subsequent territorial changes. The 1974 substitution date is given as 21 January 1972 in the later compilation/1986 note, whereas the judgment prints 25 January 1972.
- limit
- Only disclosed provision and amendment-note bounds reviewed. The judgment itself records deletion of the government-service exclusion by the 1970 Act. No complete amendment chain, gazette-date adjudication, current-law validation or 2025 mapping.

- Caption uses N. Takim Roy Rymbai; the judicial opening prints R. Takin Roy Rymbai. The caption title is retained and the variant is not silently harmonised.; The appellate caption identifies a High Court judgment of 11 October 1974 but lists some underlying Civil Rule years as 1976 and 1975. The impossible chronology is preserved as a reporter inconsistency; no corrected lower-court docket years are invented. The Supreme Court group is clearly Civil Appeals Nos.579–594 of 1975.; The judgment prints 25 January 1972 for the 1974 territorial adaptation’s effective date; the separately checked official-hosted 2011 compilation and official 1986 amendment note give 21 January 1972. No primary Gazette reconciliation was completed.; The headnote’s description of office location and the Officer’s conclusion must not be read as a Supreme Court finding of salary source. SCR 418 D and 422 E–F expressly reserve that issue.; The government-service exclusion and its invalidation concerned the earlier statutory version. The adjacent section 10(26A) government-service omission in later compilation notes is a different provision.; The sham-partnership discussion is a legislative-policy illustration, not an allegation or finding about the respondent.
- AY 1970–71 is expressly stated for the respondent in Civil Appeal No.579 of 1975. The common judgment does not separately specify the years or individual facts for the other fifteen appeals; none are inferred.
