“5. In view of the acute problem of unemployment, whenever few vacancies are notified by any public authority, it is common that thousands of applicants apply for such posts. If the applicants are permitted to rectify applications after cut-off dates, the same would render the scrutiny process indefinite. In the course of such recruitment process, many persons, though they belong to the OBC category or SC/ST category, might not have obtained the required caste certificate before the cut-off date. Such persons, being law abiding and being conscious of the bar contained in the notification of the cut-off date, might not have applied seeking employment. In case the authority starts accepting caste certificates subsequent to the prescribed cut-off dates whenever a candidate approaches the authority, the remaining candidates who had not applied would definitely be affected.
