Gandhinagar: Gujarat government may have to go in for major changes in the state’s land-related laws which are currently being applied for regularizing land titles – in case it wants to apply the new impact fee law, passed in the state assembly in September 2011 for legalizing illegal structures constructed on plots of land without necessary clearances. Top Sachivalaya sources said this is particularly crucial as of 15-lakh-odd illegal structures, which the law seeks to regularize, two-thirds are land related.
