What is the role of "unfilled vacancies" under clause (4B)?
Under clause (4B), the role of "unfilled vacancies" is to be considered as a separate class of vacancies to be filled up in any succeeding year or years, when there are no available candidates for reservation from the respective backward classes or Scheduled Castes and Scheduled Tribes. These unfilled vacancies reserved for being filled up in that year in accordance with any provision for reservation made under clause (4) or clause (4A), will not be considered together with the vacancies of the year in which they are being filled up for determining the ceiling of fifty per cent. reservation on total number of vacancies of that year.
