which came into force on 3-3-2005. Prior to amendment, clause (b) provided for assignment of larger extents, namely, not more than one acre in the plains and not more than one acre of wet land or three acres of dry land in hilly tracts, if there are no improvements in the land, and where there are improvements effected on the land by the occupant, not more than two acres in the plains and not more than two acres of wet land or four acres of dry land in hilly tracts. It is stated by the petitioner that the land in question is not in hilly tracts. Therefore, the maximum extent that could be assigned, before the amendment of the Rules in 2005, is one acre or two acres, depending on the question whether the petitioner has effected valuable improvements in the land. The amended Rules would apply to any assignment after the amendment, irrespective of the date of application and therefore, the maximum extent that could be assigned to the petitioner, if he is entitled to get assignment, is not more than fifty cents of land. “
