submitted the L.T.C. claim of Rs.1,48,300/- to the respondent no.2 for audit and for balance payment. The claim of the petitioner was returned back by the respondent no.2 on 31.5.2012 as the petitioner had purchased the tickets from the agent that was not authorized by the respondents. Since the petitioner learnt that the cases in regard to the return of the irregular claims were being considered by the Ministry of Finance for one time relaxation vide communication dated 22.2.2012, the petitioner resubmitted the claim. At the time of resubmission, the petitioner found that the travel agent had charged an amount of Rs.4,300/- in excess and accordingly, the petitioner resubmitted the claim by deducting the excess amount of Rs.4,300/-. The claim was, however, returned by the impugned communication dated 13.12.2013 as the petitioner had not purchased the air tickets from one of the agencies mentioned in the circular and had purchased the same from a private agent. The petitioner has impugned the communication dated 13.12.2013 by the instant petition. By an amendment to the petition, the petitioner has also challenged the circular dated 16.9.2010, so far as it imposes the condition of purchasing the air tickets from the authorized travel agencies, as being unconstitutional, illogical, irrational and discriminatory.
