Vertical vs Horizontal Reservation in Seats: Supreme Court Insights

Disclaimer: This blog post provides general information on reservation policies based on Indian court judgments. It is not legal advice. Consult a qualified lawyer for specific cases, as outcomes depend on individual circumstances.

Reservations in India aim to promote equality by addressing historical disadvantages. However, confusion often arises between vertical reservation and horizontal reservation in seats for jobs, education, and elections. If you've searched for Verticle Horizental Reservation Seats (noting the common misspelling of Vertical Horizontal), this guide clarifies these concepts using key Supreme Court rulings.

We'll break down definitions, differences, application methods, and real-world examples from landmark cases. Understanding this can help candidates in competitive exams, job selections, and admissions avoid common pitfalls.

What is Vertical Reservation?

Vertical reservation (also called social reservation) allocates a fixed percentage of seats or posts to specific social groups like Scheduled Castes (SC), Scheduled Tribes (ST), and Other Backward Classes (OBC). These are compartmentalized quotas.

• Typically capped at 50% total (15% SC, 7.5% ST, 27% OBC), as per Indra Sawhney v. Union of India (1992).


• Seats are filled separately within each category based on merit among eligible candidates.


• Example: In 100 seats, 50 might be unreserved (open/general), 15 for SC, etc. Rajesh Kumar Daria VS Rajasthan Public Service Commission - 2007 Supreme(SC) 973

Vertical reservations create distinct pools that do not overlap. A meritorious SC candidate can migrate to the open category without counting against SC quota. SAURAV YADAV VS STATE OF UTTAR PRADESH - 2020 7 Supreme 243

What is Horizontal Reservation?

Horizontal reservation (special reservation) cuts across vertical categories. It applies proportionally to open seats and reserved seats. Common examples include:

• Women (often 20-33%)


• Persons with Disabilities (PwD) (3-4% under RPwD Act, 2016)


• Ex-servicemen (5-10%)

Key principle: Horizontal reservation has to be provided by cutting across amongst vertical reservation. Satpal VS Oriental Bank of Commerce - 2017 Supreme(Raj) 249

• It's not a separate pool but an interlocking quota. Women from SC get counted in both SC (vertical) and women (horizontal) quotas.


• Importantly, horizontal quotas like women or PwD do not count toward the 50% vertical cap. Union of India VS National Federation of the Blind - 2013 7 Supreme 129 Mahesh Gupta VS Yashwant Kumar Ahirwar - 2007 6 Supreme 276

Key Differences: Vertical vs Horizontal

| Aspect | Vertical Reservation | Horizontal Reservation |
|--------|----------------------|------------------------|
| Basis | Social backwardness (SC/ST/OBC) | Special categories (women, PwD, ex-servicemen) A. P. Public Service Commission VS Baloji Badhavath - 2009 4 Supreme 17 |
| Application | Separate compartments | Cuts across all vertical categories |
| 50% Cap | Counts toward limit | Outside the limit Union of India VS National Federation of the Blind - 2013 7 Supreme 129 |
| Migration | Merit-based to open category possible | Compartmentalized; limited migration Pinki Asati VS State of M. P. - 2020 Supreme(MP) 509 |
| Example | 27% OBC seats filled from OBC candidates | 30% women seats from all categories, including OBC women |

As explained: Horizontal (special) reservation differs from vertical (social) reservation – Thus women selected on merit within the vertical reservation quota will be counted against the horizontal reservation for women. Public Service Commission, Uttaranchal VS Mamta Bisht - 2010 4 Supreme 504

How Seats Are Filled: Step-by-Step Process

Supreme Court rulings provide a clear method to avoid errors like excess selection. Follow this sequence:

1. Prepare overall merit list (ignoring categories initially).


2. Allocate open/general seats to top merit candidates (e.g., 50-65%).


3. Fill vertical quotas (SC/ST/OBC) from category-specific merit lists, adjusting for those already in open list. SAURAV YADAV VS STATE OF UTTAR PRADESH - 2020 7 Supreme 243


4. Apply horizontal quotas by pulling up candidates across categories if needed. For example:


5. If fewer SC women qualify, pull from general women merit.


6. Ex-servicemen: If an ex-serviceman candidate secured lesser marks than the last candidate in the vertical reservation category, the ex-serviceman candidate shall be pulled up. Satpal son of Shri Lal Chand Saharan by caste Saharan VS Oriental Bank Of Commerce - 2017 Supreme(Raj) 124

Illustration from Anil Kumar Gupta v. State of U.P.: 20% women reservation is horizontal within vertical quotas; misapplication led to excess women selections, but courts granted limited relief without disturbing entire lists. Rajesh Kumar Daria VS Rajasthan Public Service Commission - 2007 Supreme(SC) 973

Common Mistake: Treating horizontal as vertical leads to over-reservation. In MBBS admissions, 30% women quota across categories was upheld, but excess open seats were created. Anil Kumar Gupta VS State Of U. P. - 1995 Supreme(SC) 767

Landmark Cases and Rulings

1. Indra Sawhney (Mandal Case) (1992)

Base for 50% cap on vertical reservations. Horizontal like PwD falls under Article 16(1), not 16(4). Union of India VS National Federation of the Blind - 2013 7 Supreme 129

2. Anil Kumar Gupta v. State of U.P. 1995 (5) SCC 173

RPSC wrongly applied 20% women as horizontal within vertical, causing excess selections. Relief to specific appellants only. Rajesh Kumar Daria VS Rajasthan Public Service Commission - 2007 Supreme(SC) 973

3. Union of India v. National Federation of the Blind (2013)

PwD 3% reservation computed on total vacancies, not just identified posts. Horizontal across all cadres. Union of India VS National Federation of the Blind - 2013 7 Supreme 129

4. Recent PwD Rulings

Reservation for persons with disability has to be computed on total number of vacancies in the cadre strength. It is a horizontal reservation. No sub-classification by caste. Kanakalta Sahu vs Paradip Port Trust - 2024 Supreme(Online)(Ori) 3470

5. Women and Ex-Servicemen

Reservation for women is horizontal; meritorious reserved women count toward it. No migration if availing relaxations. SAURAV YADAV VS STATE OF UTTAR PRADESH - 2020 7 Supreme 243 Gaurav Verma vs Airport Authority of India - 2026 Supreme(Del) 141

6. Medical Admissions and AIQ

Horizontal women quota upheld, but total cannot exceed limits. States cannot alter All India Quota reservations. Ashish Sharma and Others v. State of Chhattisgarh and Others - 2004 Supreme(Online)(Chh) 16 Neil Aurelio Nunes VS Union of India - 2022 Supreme(SC) 103

Challenges and Misapplications

• Excess Selection: RPSC selected extra women due to faulty policy; court allowed partial relief. Rajesh Kumar Daria VS Rajasthan Public Service Commission - 2007 Supreme(SC) 973


• PwD Computation: Must be on total cadre, not post-wise. Union of India VS National Federation of the Blind - 2013 7 Supreme 129


• No Right to Reservation: No citizen of India can claim reservation as a matter of right. A. P. Public Service Commission VS Baloji Badhavath - 2009 4 Supreme 17

In elections/panchayats, aggregate vertical reservations cannot exceed 50%; rotation applies. Ajay Kumar VS State Of U. P. Thru. Addl. Chief Secy. Panchayat Raj, Lko. - 2021 Supreme(All) 258

Key Takeaways

• Vertical: SC/ST/OBC – fixed pools, 50% cap.


• Horizontal: Women/PwD/Ex-SM – cross-cutting, outside cap.


• Filling Rule: Merit first, then vertical, then adjust horizontal.


• 50% Rule: Applies only to vertical; horizontal adds without breaching. Mahesh Gupta VS Yashwant Kumar Ahirwar - 2007 6 Supreme 276


• Courts intervene only for gross errors, often protecting existing appointments.

Grasping vertical horizontal reservation seats ensures fair competition. Misapplication can lead to writ petitions, but merit remains paramount. For personalized guidance, seek expert advice.
