The Calcutta High Court set aside an employment rejection based solely on colour blindness, holding that such disqualification requires a demonstrable functional nexus to the specific job duties under the employer's Medical Attendance Rules. The court found Coal India's rejection of Surendra Kumar Gupta for an Accountant post arbitrary as its own rules confined colour blindness testing to Group A (mining-connected) employees, not Group B office roles like accounting.
Background & Facts
The Dispute
The petitioner, Surendra Kumar Gupta, an Other Backward Class candidate, applied for the post of Accountant/Cost Accountant (T & S Grade 'A') at Eastern Coalfields Limited (ECL) following Employment Notification No. ECL/CMD/C -6/Rectt./Acct -19/36/619 dated 28th September, 2019. He appeared in the provisional selection list published on 13th November, 2021, but was declared "Unfit for Employment" via letter dated 16th December, 2021, due to colour blindness detected during Initial Medical Examination (IME) conducted on 06th-07th December, 2021.
Key Facts
- The petitioner meets minimum physical standards for all employee classes under MAR Clause 1-A
- His role as Accountant/Cost Accountant is office-based, involving no underground mining, machinery operation, or authorised driving
- ECL's Medical Attendance Rules (MAR) Chapter VIII classifies employees into Group A (mining-connected) and Group B (all others)
- MAR Clause 1-A requires compulsory night vision and colour blindness testing for Group A appointees
- MAR contains no mention of colour blindness testing for Group B employees
- A CMO/HOD Medical, CIL advisory dated 14th July, 2016 explicitly states: "according to MAR, there is no mention of testing colour blindness for persons falling under Group B"
- The impugned letter dated 16th December, 2021 cited "Colour Blindness" as the sole reason for unfitness
- Seven other provisionally selected candidates below the petitioner received appointment letters despite similar colour blindness status
- CIL issued a clarification on 3rd August, 2022 stating colour blindness testing would be conducted for all concerned, though acceptance may not extend to posts requiring effective colour discrimination

The Parties' Positions
Petitioner's Contention: The MAR's functional classification places Accountants in Group B where colour blindness testing is not required; rejection violates Articles 14 and 16 as no functional nexus exists between colour blindness and accounting duties; reliance on Nandkumar Narayanrao Ghodmare v. State of Maharashtra and Ashes Kumar Roy v. CIL.
Respondent's Contention: Mines Rules 1955 extend medical requirements to all ECL employees; modern accounting involves colour-coded data requiring effective colour discrimination; reliance on Tarun Pan v. State of WB and Ali Hossain Mandal v. W.B. Board of Primary Education.
Relief Sought
The petitioner sought: (i) setting aside the 16th December, 2021 rejection letter; (ii) direction to appoint him to the Accountant/Cost Accountant post; (iii) necessary consequential steps for appointment letter issuance.
The Legal Issue
The central question was whether colour blindness, without a demonstrated functional nexus to the duties of an Accountant/Cost Accountant post, could constitute a valid ground for denial of employment under Coal India Limited's Medical Attendance Rules.
Arguments Presented
For the Petitioner
Counsel argued that MAR's Group A/B classification is functionally based on actual job duties, not pay grades; the petitioner's office-based accounting role falls under Group B where MAR expressly omits colour blindness testing requirements; the 2016 CMO advisory confirms this interpretation; rejecting the petitioner solely on colour blindness violates the functional nexus principle established in Nandkumar Narayanrao Ghodmare (supra) and Ashes Kumar Roy (supra); the respondent's post-hoc reliance on Mines Rules cannot override MAR's specific functional classification.
For the Respondent
Counsel contended that Mines Rules 1955's statutory definition of "mine" includes offices connected to mining operations, thus applying medical standards universally; modern accounting necessitates colour discrimination for interpreting charts and graphs; the 3rd August, 2022 CIL clarification supports colour blindness testing for all roles; reliance on Tarun Pan (supra) affirmed that selection panel inclusion does not create indefeasible right to appointment.
The Court's Analysis
The Court began by emphasizing that MAR's Group A/B classification is a "conscious" functional distinction made by the employer to prescribe appropriate physical standards at pre-employment examination. It stressed that "the medical standard must necessarily be applied with reference to the category in which the concerned employee falls." The Court noted MAR Clause 1-A's textual scheme limits compulsory night vision and colour blindness testing to Group A employees only, with no such requirement for Group B.
The 2016 CMO advisory was deemed "of considerable significance" as an internal directive reiterating strict adherence to MAR and Mines Rules, explicitly stating MAR contains "no mention of testing colour blindness for persons falling under Group B." The Court rejected the respondent's attempt to equate the advertisement's "T & S Grade 'A'" designation with MAR's Group A, holding that "the latter is a functional classification for determining physical and medical standards" while the former is merely a "grade or service classification."
Applying the functional nexus principle from Nandkumar Narayanrao Ghodmare (supra), the Court found no evidence that colour blindness interferes with accounting duties: "Nothing has been placed before this Court to establish that the duties attached to the post require the petitioner to perform underground mining work, operate mining machinery, drive authorised vehicles, undertake electrical or mechanical work, or perform any other function in which colour discrimination is inherently connected with safety or efficient discharge of duties." The respondent's assertion that modern accounting requires effective colour discrimination was deemed "unsupported by any contemporaneous recruitment condition, prescribed job specification, medical standard or other material."
The Court held that the respondent's post-August 2022 clarification cannot retrospectively supply a disqualification absent at the relevant recruitment stage, citing Tej Prakash Pathak v. Rajasthan High Court (2025) on maintaining notified eligibility criteria sanctity. Ultimately, the rejection was found "contrary to the applicable Medical Attendance Rules, unsupported by any demonstrated functional necessity and consequently arbitrary in law."
The Verdict
The petitioner succeeded. The Court set aside the rejection letter dated 16th December, 2021, directed respondents to give effect to the provisional selection for the Accountant/Cost Accountant (T & S Grade 'A') post by treating colour blindness as non-disqualifying, and ordered necessary consequential steps for appointment letter issuance within four weeks from the judgment's communication date.
What This Means For Similar Cases
Functional Nexus Is Non-Negotiable
Employers cannot rely on abstract medical conditions to disqualify candidates; disqualification requires proof that the condition impairs performance of specific job duties. For office roles like accounting, colour blindness alone is insufficient grounds for rejection without evidence of functional impact on core duties such as financial analysis or report preparation.
Employer's Own Rules Govern
When an employer establishes functional classifications (like MAR's Group A/B), medical standards must be applied strictly within that framework. Internal advisories clarifying rule interpretation (e.g., the 2016 CMO letter) carry significant weight in determining applicable standards, and post-recruitment clarifications cannot alter the recruitment-stage criteria.
Administrative Discretion Has Limits
Public employment decisions must align with notified rules; authorities cannot substitute their own standards for prescribed ones. The doctrine that "no person should suffer because of an act of the Court" requires remedies to neutralize unlawful administrative action, hence the four-week compliance timeline to prevent irreversible consequences from time's efflux.
