( 1 ) IN this batch of Writ Petitions, the petitioners are questioning the validity and competence of the Municipal Corporation of Hyderabad to insist upon the production of a no-objection certificate from the District Collector, Hyderabad, as a precondition for sanctioning the layout applied for by the petitioners. The individual facts of these several Writ Petitions are not relevant for the purpose of deciding the question arising herein, and it would be sufficient if we set out the facts in the first Writ Petition, viz. , W. P. No. 4920/1984. A. The petitioner in the aforesaid writ petition says that, he is the owner of half portion of Plot No. 1, situated at Jubilee Hills, Banjara Hills, Hyderabad; that, he had purchased the same under a registered sale deed dt. 10-10-1970 from one T. V. Ramachandraiah who, in turn, is said to have purchased the same, along with some other land, from one Shamim Begum in 1967. The petitioner applied to the Municipal corporation for sanction of layout in respect of the said plot, along with a plan. The Municipal Corporation, by its proceedings dt. 17-11-1981, directed the petitioner to demarcate the roads, plots and boundaries. T
