promotional avenue in the police department is from Grade-II to Grade-I, Head Constable, Sub-Inspector and Inspector of Police. While the petitioners were serving in Salem Range, there was a vacancy in the promottee quota and in view of the same, they were promoted as SubInspector of Police on temporary basis on 11.07.2007. However, their probation was not declared after completion of two years period in SubInspector of Police. Had their probation been declared within a period of two years, their names would have been included in the 'A' list in the year 2009 itself. However, the second respondent, by an order dated 27.12.2010, directed the third respondent to pass consequential order. Subsequently, after a lapse of one year, the second respondent, by an order dated 11.12.2011, included the names of the petitioners in the 'C' list of regular Sub-Inspector of Police for the year 2010. Although the crucial date is 01.01.2010, the department fixed the crucial date as 06.09.2011 erroneously.
