one such allotment letter so far as the petitioner no. 1 is concerned is dated 17.12.2005. On a bare perusal of such allotment letters, it appears that a relationship of landlord and tenant would appear. However, at the same time, there is a clause which empowers the ASTC to issue vacation orders by which the allottee would be required to vacate the premises within a period of a month if the space is required by the ASTC for its own use.

The requirement of the land as an exchange with the NF Railway for creating a second entry point to the Guwahati Railway Station is undoubtedly for public purpose and the petitioners have also fairly conceded to this point. In view of the above, the argument made on behalf of the petitioners that they are tenants under the Act of 1972 is not acceptable.
