Calcutta High Court, Appellate Side (Reetobroto Kumar Mitra, J.), WPA 6468 of 2026, delivered 21.05.2026 — An Associate Professor of the Indian Statistical Institute challenged the initiation of disciplinary proceedings against him, in essence the chargesheet/articles of charge dated 09.01.2026 issued by respondent no. 5 (Prof. Pallab Banerji, HAG professor of IIT Kharagpur and Council member), who was appointed alternate Disciplinary Authority after the Officiating Director — the designated DA under Rule 10 read with Appendix II of the Standing Service Orders, 1963 — recused herself being a central figure of the incident of 07.10.2025. Held, dismissing the petition: (i) at the stage of show cause notice/chargesheet the only sustainable ground of challenge is jurisdictional deficiency of the authority (following Oryx Fisheries); (ii) an Officiating Director appointed by the Chairman under Bye-law 6.5.3 for an emergent six-month term exercises the same powers as the Director and validly acts as designated DA; (iii) the Chairman-approved appointment of respondent no. 5 as alternate DA, communicated by the Chief Executive Officer on 11.11.2025, was an administrative function within jurisdiction — the Note to Clause 12.4 of the Service Orders of 1963 (deeming a non-employee Council member to be above employee rank) applies by analogy, respondent no. 5 being of higher rank than the petitioner; (iv) Clause 11.2.1 must be harmoniously construed with Appendix II, the petitioner not being under the direction and control of his divisional head for this purpose; (v) no bias — the articles of charge merely set out the statements and charges; the Deputy Director's complaint was maintainable as that of a person aggrieved present at the incident, and the tentative witness list could not be assailed at this stage; (vi) the CCS (Conduct) Rules, 1964 apply through Appendix IV Clause 5.1 (deeming of Government of India rules) as the institute has no conduct rules of its own; (vii) the petitioner never raised jurisdictional deficiency in his three replies to the show cause notice.
