Section 78(A) of Electricity Supply Act, 1948 that the Board should follow the procedure followed by the Andhra Pradesh Public Service Commission in respect of recruitment of Assistant Engineers. This letter specified that the APPSC was considering the candidates qualified who had obtained 40 marks (for OC) and 35 marks (for BC) for the purpose of being called for oral interview. The respondent Board was directed by the Government, exercising the power under Section 78-A of Electricity Supply Act, 1948, to follow the above procedure. Accordingly, the procedure directed by the Government in its letter dated 20-03-1986 was followed and since the petitioner did not secure 40% marks being an O.C. candidate (in the written examination) and had secured only 31 marks, she was not selected. Additional affidavit filed by the respondent further asserts that even in the application issued for the recruitment, it is clearly specified that only those candidates who qualified in written examination with a minimum the qualifying marks as specified would be called for interview in the ratio of 1:2. The copy of application form has been annexed to the counter affidavit and it clearly shows that guideline No.7 in the application form annexed to the application form clearly specifies that O.C. candidates are required to obtain 40% marks at the written examination for being called for interview.
