West Bengal State Electricity Transmission Co. Ltd. issued a recruitment notification for 30 posts of Junior Engineer (Civil) Grade II, including one post reserved for UR (PWD-LV) — an unreserved post carrying a horizontal reservation for Persons with Disabilities (Low Vision). The notification stipulated that if no qualified UR (PWD-LV) candidate was available, the vacancy would be filled by PWD candidates of other categories as per merit. Respondent No. 1 (an unreserved PWD-LV candidate) scored 55.667 marks; Respondent No. 3 (an OBC-A candidate who also belonged to the PWD-LV category) scored 66.667 marks. The appellant-employer offered appointment to Respondent No. 3 on merit. Respondent No. 1 challenged this before the Calcutta High Court. The Single Bench dismissed the writ petition; the Division Bench reversed, holding that so long as a qualified unreserved PWD-LV candidate was available, no reserved-category PWD-LV candidate could be appointed to the UR (PWD-LV) post.
The Supreme Court set aside the Division Bench's order and restored the Single Bench's decision. The Court held that the "Unreserved" category is not a communal or social category — it is an open pool available to all candidates irrespective of social categorisation. When a horizontal (special) reservation for PWD-LV is carved out within the Unreserved category, the post remains open to every PWD-LV candidate from any vertical social category (SC, ST, OBC or unreserved), and the sole criterion for appointment is merit. The principle of migration/mobility — well-settled since Indra Sawhney v. Union of India and restated in Saurav Yadav v. State of UP — applies equally to horizontal reservations under the Unreserved category. A less meritorious unreserved PWD-LV candidate cannot be preferred over a more meritorious OBC-A PWD-LV candidate; to hold otherwise would be patently arbitrary and violative of Articles 14 and 16.
The Court further clarified that the notification's condition ("in case of non-availability of qualified UR (PWD-LV) candidate…") merely states the obvious — it does not erect an absolute bar against meritorious reserved-category PWD-LV candidates when an unreserved PWD-LV candidate is present. The Court also noted, following Deepa E.V. v. Union of India and Union of India v. Sajib Roy, that a reserved candidate migrating to an unreserved post must not have availed any relaxation in essential qualifications — a condition satisfied on the facts, as Respondent No. 3 had availed no such relaxation.
