Admittedly, the provisional patta granted in favour of the 1st petitioner, who was an ex-serviceman, was cancelled long back and the said order of cancellation has become final. However, having considered his request for alienation of the assigned land, the respondents passed an order dated 11.7.1997 fixing the consideration at the rate of Rs.350/- per sq. yard. The mere fact the land situated in the same survey number was alienated to different class of persons on payment of concessional rate of Rs.1/- per sq. yard would not render the impugned action of the respondents arbitrary or discriminatory. It is also relevant to note that admittedly the land in question is a poramboke land and it is for the Government to consider the request for alienation taking into consideration the particular facts and circumstances and varying needs of different classes of persons. The 1st petitioner, who had never challenged the cancellation of the provisional assignment, cannot claim to have acquired any right much less legal right to purchase the said land at a particular price, nor any case is made out to show that the respondents in fixing the price of the land at Rs.350/- per sq. yard had acted in breach of any statutory obligation. On the face of it the matter does not involve enforcement of any legal right or statutory obligation and, therefore, it is not open to the petitioners to seek a writ of mandamus.
