3.It is pertinent to note that, for the promotion to be given in the year 1992, the appellant submitted his representation only in the year 2010, i.e., after a lapse of nearly 18 years. The learned Single Judge taking into consideration the delay in submitting the appellant's representation, dismissed the writ petition, finding that, if the appellant's representation is considered, that will unsettle the settled things. The learned Single Judge also relied upon the judgment of the Hon'ble Supreme Court reported in AIR 1974 SC 2271 [P.S.Sadasivaswamy v. State of Tamil Nadu). wherein, the Apex Court held that, as far as promotion is concerned, one should approach the Court within a period of six moths and in extraordinary cases, within a period of one year. When the petitioner had filed the writ petition only in the year 2010, after a lapse of 18 years, the learned Single Judge has rightly dismissed the writ petition.
