which have been put to uses other than land use specified in the development plans. So far as clause (a) category of uses are concerned, per se we find no illegality in the approach of the Government. The Government has the authority in terms of Section 90B of the Act of 1956 as it stood at the relevant time and Section 90-A as it stands today to regularise such unauthorised land conversions. However so far as clause (b) is concerned, any such regularisation of the land use, must strictly conform to the Gulab Kothari judgments. In other words, if the current land use is different from the land use permissible under the sanctioned development plan, the same would not be regularised unless and until to the extent permissible and after following the procedure as envisaged, the development plan is modified. While doing so, all rigours, restrictions and directions contained in Gulab Kothari judgments would apply. Nothing stated in this judgment would be taken as having diluted any of these directions.
