that the Petitioner-Appellant was only required to look after and discharge the duties of the officiating Principal but was never promoted/appointed on the said post. In other words, it can be said that the Petitioner-Appellant was given only current duty charge in addition to her substantive post and this arrangement did not result in promotion to the post of which, the current duty charge was handed over. In State of Haryana Vs. S.M. Sharma AIR 1993 SC 2273 , the Chief Administrator of the Board entrusted Sri S.M. Sharma, with the current duty charge of the post of Executive Engineer, which was subsequently withdrawn as a result of his transfer to other post. He challenged the said order stating that it amounts to reversion. The Apex Court held that Sri Sharma was only having current duty charge of the Executive Engineer and was never promoted or appointed to the aforesaid post and therefore, on transfer to some other post, it did not result in reversion from the post of Executive Engineer.
