“20. Scheme of Regulations 101 to 107 makes it clear that after receiving an intimation of vacancy, the District Inspector of Schools is empowered to send the application of member of deceased employee, who is entitled for compassionate appointment to the institution, who has to issue appointment letter to such candidate. It is, however, implied in the scheme that in the event there is no candidate entitled for compassionate appointment to fill a particular vacancy, the intimation of which has been received by the District Inspector of Schools, the District Inspector of Schools can direct the appointing authority to fill up vacancy by direct recruitment but even in a case the selection is made by direct recruitment by the Principal/committee of management, prior approval is required of the District Inspector of Schools before issuing an appointment letter to the selected candidate. Without prior approval of the Inspector, the Principal or the committee of management cannot issue an appointment letter or permit joining of any candidate. The requirement of prior approval in Regulation 101 is a condition precedent before issuing an appointment letter and is mandatory. The observation of the learned single Judge in the case of Dingur v. District Inspector of Schools, Mirzapur (supra) as quoted above, is also to the effect that approval has to be considered by the District Inspector of Schools after examining ,the proceeding relating to appointment and after examining as to whether prescribed procedure in a fair manner has been followed or not.
