21.According to para-23(2) of the Full Bench Judgment, the minimum strength of the required teachers in Elementary School with 5 Standards shall be 5, out of which, one would be the Head Master. If this is the position, where the Elementary School, having 5 standards, would be entitled to claim sanctioning of 5 secondary grade teachers out of which, one can be designated as Headmaster and their very policy of the Government is reflected in 5(1)A of the said GO which would state that the elementary school which is having strength up to 80, out of two secondary grade teachers, one can be in the grade of Headmaster. So, certainly, the designation of the petitioner as Headmistress in the third respondent school in the year 1994 itself cannot be found fault with, because, the policy of the Government as reflected in G.O.Ms.No.525 and the mandatory guidelines given in the judgment of this Court in 2006(5) CTC 385, by the order, dated 4.11.2016 would only strengthen the stand of the third respondent school that atleast one out of the two secondary grade teachers sanctioned to the school can be either designated or shall be in the grade of Head Master/Headmistress. So, this is what had been done by the third respondent from 1994 whereby the petitioner had been designated as Headmistress and the same also been approved by the second respondent where the second respondent has also fixed the salary to the petitioner. This arrangement had been continuing for several years. Nothing had come in the negative from the respondents department probably, because of the policy decision in the meanwhile come out by G.O.No.525 and also mandatory Guidelines of this Court referred to above. Subsequently, after several years, only in the year 2002, actual sanction of a Headmaster has been made. Merely because, the respondents department has given a sanction to the Head Master post to the third respondent after a decade or more, that would not take away the right of the third respondent to designate one of the secondary grade teachers as Headmistress of the school, as without a Headmaster, as stated above, no school can be functioning and also rightly the said appointment had been approved by the second respondent.
