Clarificatory Letters Cannot Amend OBC Creamy Layer Norms: Salary-Only Exclusion Invalid and Parity Required for PSU/Private and Government Employees

1. Introduction

UNION OF INDIA v. ROHIT NATHAN (2026 INSC 230, decided on 11-03-2026) is a common judgment disposing of three sets of civil appeals arising from orders of the Madras High Court (31.08.2017), the Delhi High Court (22.03.2018), and the Kerala High Court (25.02.2022). The appellants were the Union of India/DoPT, and the respondents were successful Civil Services Examination candidates seeking recognition as OBC (Non-Creamy Layer).

The recurring administrative trigger was DoPT’s denial of OBC-NCL benefit to candidates whose parents were employed in PSUs/banks/private organisations under Category II(C) of the Schedule to the Office Memorandum dated 08.09.1993 (“1993 OM”), on the ground that the parental salary exceeded the creamy-layer income ceiling, relying on the DoPT’s Letter dated 14.10.2004 (“2004 Letter”).

The Supreme Court framed two broad questions of law:

• Issue 1: Whether the 2004 Letter can override/supersede the 1993 OM governing creamy layer exclusion.
• Issue 2: Whether treating wards of PSU/private employees differently from wards of Government employees (for similar grades/classes of posts) amounts to hostile discrimination under Articles 14–16.

2. Summary of the Judgment

The Supreme Court dismissed all appeals and upheld the impugned High Court decisions. It held, in substance, that:

• A clarificatory letter cannot override, amend, or dilute the parent executive policy (the 1993 OM); if it travels beyond clarification and alters rights/liabilities, it becomes legally untenable.
• Creamy layer determination cannot be made solely on parental salary without anchoring the enquiry to the 1993 OM’s status/post-based architecture (especially within the Service Category).
• Applying salary-based exclusion to PSU/private employees while not doing so for similarly placed Government employees creates hostile discrimination (equals treated unequally) and violates the equality code.
• The Union/DoPT was directed to consider claims of respondents and intervenors as per the judgment and implement within six months. The Court also directed creation of supernumerary posts “as required” to accommodate eligible candidates.

3. Analysis

3.1 Precedents Cited (and their Role)

(A) Creamy layer as a constitutional imperative

• Indra Sawhney and others v. Union of India and others (1992 Supp (3) SCC 217): The constitutional source of the “creamy layer” exclusion. The judgment reiterates Indra Sawhney’s core idea: the backward class is a collectivity, but advanced individuals/sections within it must be excluded to prevent monopolisation and to preserve substantive equality. This case supplied the normative yardstick against which the 1993 OM and later “clarifications” were judged.
• Indra Sawhney v. Union Of India and others ((2000) 1 SCC 168) (as cited in submissions): Relied on by the Union to argue that non-exclusion of creamy layer violates Articles 14 and 16 (unequals cannot be treated as equals). The Court accepted the general proposition but insisted that the method of exclusion must remain faithful to the governing framework (1993 OM) and equality.
• Ashok Kumar Thakur v. Union of India ((2008) 6 SCC 1): Cited to support periodic review and meaningful creamy-layer exclusion. The Court treated it as reaffirming the principle that backwardness is not permanent, but it did not accept that this permits salary-only disqualification through a subordinate “clarification” that creates unequal treatment.
• State of Kerala and Others v. N.M. Thomas and Others (MANU/SC/0479/1975 : 19.09.1975 - SC) and its approval in Indra Sawhney and others v. Union of India and Others (1992 Supp (3) SCC 217): These authorities were used to emphasise that Article 16(4) is not a carve-out hostile to equality, but a method of achieving equality. Therefore, a creamy-layer rule that itself produces arbitrary inequality is constitutionally suspect.

(B) The doctrinal evolution: caste, poverty, means test

• M.R. Balaji and others v. State of Mysore (AIR 1963 SC 649) and State of Andhra Pradesh and another v. P. Sagar (1968 SCR (3) 595): Cited by the Court in its constitutional background to reiterate that caste may be relevant, but cannot be the only determinant; excessive or irrational classification subverts equality.
• K.C. Vasanth Kumar and another v. State of Karnataka (1985 SCC OnLine SC 339), K.S. Jayasree v. State of Kerala ((1976) 3 SCC 730), and R. Chitralekha v. State Of Mysore ((1964) 6 SCR 368 : AIR 1964 SC 1823): These cases were referenced to show the jurisprudential legitimacy of “means” as a refining criterion within backward classes, but only when deployed rationally, consistently, and without producing new inequities.

(C) Limits of executive “letters” and administrative invalidity

• R.P. Bhardwaj v. Union of India ((2005) 10 SCC 244) and K. Sampath v. State of Tamil Nadu (MANU/TN/9958/2006): Invoked by respondents to argue that an operative Office Memorandum cannot be modified by a mere letter. The Court’s reasoning aligns with this principle: a “clarification” cannot introduce a substantive new exclusion mechanism.
• Madhuri Patil v. Commissioner, Tribal Development ((1994) 6 SCC 241): Cited (in submissions) for the broader principle that caste/status certificates carry presumptive validity unless set aside by the competent scrutiny mechanism. While the Supreme Court did not decide the dispute on certificate-finality alone, the citation reinforced caution against ad hoc administrative negation of certified status.

(D) Article 142 and supernumerary posts

• Sushma Gosain v. Union of India ((1989) 4 SCC 468), Dr. PPC Rawani v. Union of India ((1992) 1 SCC 331), Union of India v. Vijay Kumari (1994 Supp (1) SCC 94), Dr. D.K. Reddy v. Union of India ((1996) 10 SCC 177), Delhi Administration v. Nand Lal Pant ((1997) 11 SCC 488), Union of India v. Parul Debnath ((2009) 14 SCC 173): Cited to support the proposition that, in exceptional circumstances, courts can direct creation of supernumerary posts to do complete justice and avoid unsettling existing cadres. The Court relied on this broad remedial approach while noting DoPT’s assurance (as recorded in the Parliamentary Committee report).

(E) Consistency in governmental stand (contextual relevance)

• Neil Aurelio Nunes v. Union of India ((2022) 4 SCC 64): Raised to highlight the Union’s prior distinction between OBC creamy-layer computation and EWS computation (salary included for EWS, excluded for OBC as per that stand). The Court treated such material as reinforcing that salary-only exclusion is not a settled, uniformly legitimate reading of the OBC framework.

3.2 Legal Reasoning

(A) The 1993 OM is the governing framework; the 2004 Letter cannot rewrite it

The Court treated the 1993 OM as the “foundational guidelines” implementing Indra Sawhney through a structured scheme: (i) primarily status/post-based exclusion (Categories I–III, especially Category II for service), and (ii) a residual Income/Wealth Test (Category VI), with express instructions on how income is to be treated.

Against this, the Court reiterated a general administrative law proposition: a mere “clarification” cannot introduce a substantive condition absent in the parent policy. If it does, it ceases to be clarificatory and effectively becomes an amendment—something a letter cannot validly accomplish in this context.

(B) Salary cannot be the sole determinant; creamy layer is not a purely income-driven idea in the service context

The Court read the scheme as requiring attention to parental status and category of post. It held that “mere determination” cannot be “decided solely” on income; doing so distorts the 1993 OM’s structure, which excludes higher service echelons (Group A/B analogues) based on status criteria that reflect social advancement.

Importantly, the Court did not accept an approach that treats the absence of “equivalence” (between PSU/private posts and Government posts) as a license to shift to salary-only disqualification. Until equivalence is determined, Category II(C) cannot be administered in a way that effectively penalises PSU/private employees’ wards more harshly than Government employees’ wards in similar grades.

(C) Paragraph 9 of the 2004 Letter cannot be read in isolation to justify salary-based exclusion

The Court scrutinised paragraphs 7–10 of the 2004 Letter and concluded, overall, that: income from salaries/agriculture/other sources should not be “clubbed” in a manner that makes salary alone decisive. It highlighted that overemphasis on paragraph 9 to make income determinative would be legally untenable.

The Court also relied on institutional materials—particularly the 21st Report of the Parliamentary Committee on Welfare of Other Backward Classes (2018-19)—which recorded that the 2004 Letter “confused” rather than clarified the position and that its provenance was problematic. This strengthened the Court’s conclusion that paragraph 9 cannot be elevated into an amendment of the 1993 OM.

(D) Hostile discrimination: parity for similarly placed Government and PSU/private employees

On Issue 2, the Court applied classic Article 14 logic (intelligible differentia + rational nexus) and held that: if Group C/D Government employees’ wards are not excluded merely because salary rose with pay commissions, then excluding wards of PSU/private employees holding equivalent lower-grade posts solely due to salary is unequal treatment of equals.

The Court framed the discrimination as particularly pernicious because reservation itself is a facet of equality; an irrational creamy-layer filter can illegally exclude genuine claimants and invert the constitutional purpose.

(E) Relief architecture: extension to intervenors and supernumerary posts

Besides dismissing the appeals, the Court directed DoPT to consider claims of respondents and intervenors under the clarified principles and implement within six months, and to create supernumerary posts “as required”. This is significant: rather than leaving similarly situated candidates to fragmented litigation, the Court signalled a systemic, compliance-oriented remedy.

3.3 Impact

• Administrative law constraint on “clarifications”: Departments cannot rely on letters to introduce substantive disqualifications inconsistent with the parent OM. This strengthens rule-of-law discipline in reservation administration.
• Uniformity and equality in creamy-layer filtration: The decision reduces scope for differential treatment between wards of Government employees and PSU/private employees when posts are comparable in level, addressing long-running “equivalence pending” distortions.
• Service allocation consequences in CSE and beyond: DoPT must re-process affected candidates (including intervenors) and may need cadre-neutral solutions (supernumerary posts) to avoid disruption.
• Policy pressure to complete equivalence exercises: The decision implicitly increases pressure on Government to undertake and notify equivalence/comparability, rather than perpetuating interim arrangements that generate litigation and inequality.

4. Complex Concepts Simplified

• “Creamy layer”: The relatively advanced members within OBCs who must be excluded so reservation benefits reach the genuinely backward. It is a constitutional requirement flowing from equality, not a discretionary policy choice.
• “Status/post-based exclusion” vs “income test”: The 1993 OM primarily excludes based on the parent’s service status (e.g., higher Groups A/B). Income/wealth operates as an additional filter, not a substitute that can be applied in a way that erases the status architecture.
• “Equivalence of posts”: A policy determination comparing PSU/private posts with Government posts to apply the same service-status criteria. Until equivalence is determined, administration must not create new inequalities.
• “Hostile discrimination”: Unequal treatment of similarly situated persons without a constitutionally valid basis—here, penalising PSU/private employees’ wards for salary while not similarly penalising Government employees’ wards in comparable lower posts.
• “Supernumerary post”: An additional, temporary post created to accommodate a candidate without displacing existing incumbents—often used as a remedial tool to implement judgments while minimising cadre/seniority disruption.

5. Conclusion

UNION OF INDIA v. ROHIT NATHAN decisively reaffirms that (i) executive “clarifications” cannot be used to amend or override the governing creamy-layer framework of the 1993 OM, (ii) creamy layer status cannot be determined solely by parental salary divorced from the OM’s status-based structure, and (iii) reservation administration must not produce hostile discrimination between similarly placed Government and PSU/private employees’ wards.

The judgment’s systemic direction—extending relief principles to intervenors and permitting supernumerary posts—positions it as a compliance-driven precedent, likely to shape OBC-NCL verification and service allocation disputes wherever “equivalence not determined” has been used to justify salary-centric exclusion.
