In order to enjoy the benefits of working in hard and harmful jobs, the applicant's job must first be confirmed as a hard and harmful job. The task of comparing and identifying hard and harmful jobs is the responsibility of the provincial committees. Also, announcing the result to the applicant and implementing the policies and approvals of the High Council of Technical Protection are other duties of the provincial committees.Although the provincial committees mainly have diagnostic competence in examining jobs, but regarding matching the job titles claimed by the applicant with the job titles that are determined as hard and harmful jobs according to the laws and regulations,They do not have such a qualification.Because the provincial committees can not, by exercising their diagnostic competence, not recognize such jobs as a hard and harmful job and reject the applicant's request.Regarding the objections to the notification of the votes of the provincial committees, the ruling of the law is also clear and it is not safe to use diagnostic competence by the provincial committees.At the same time, in examining the job titles that are not determined as a hard and harmful job according to the laws and regulations,The diagnostic competence of the provincial committees remains intact, and the branches of the Administrative Court of Justice will be obliged to deal with the issue based on the mechanism of Article 64 of the Law of the Administrative Court of Justice in order to comply with the technical and specialized aspects of the matter.
