Reservation has always been a highly contested subject in India. The binaries between ‘reserved’ vs ‘deserved’ are created to show a picture where meritorious students are not picked and instead those with less merit get picked on the basis of reservation. The fight is put between the unreserved category candidates and those who come under SC/ST and OBC category.
But there is an another category which cuts across the two sides is Persons with Disability (PwD) who are entitled to get 3% reservation as per the Pwd Act 1995. This reservation is called ‘horizontal reservation’ because anyone from any category can be a person with disabilities. Seats in various government services are identified as per the physical requirements of a candidate required for that particular job.
