under DCR 33(7), a report is forwarded by the concerned Executive Engineer to the Second Respondent, inter alia, in respect of the status of the building, certifying the list of the occupants/tenants in accordance with Clause-14(4) and 14 of Appendix-III to DCR 33(7). On 14 August 2002, the Second Respondent issued a no objection certificate for redevelopment and certified 12 tenants/occupants in respect of the building. The inspection extract of the Municipal Corporation certified that there were 12 tenants/occupants of which 7 were residential and 5 were non-residential. The inspection extract pertains to 1995-96. However, the Petitioners submitted a representation to the office of the Executive Engineer, C-III Division contending that the tenants at serial numbers 5 and 6, 7 and 8 and 11 be considered as non-residential and submitted sub-tenancy agreements and declarations in support of the submission. Based on those documents, the then Executive Engineer submitted a revised proposal to consider the said tenants/occupants as non-residential and furnished a modified list of tenants. Based thereon, a no objection certificate was issued on 14 August 2002. On 21 February 2007, a complaint was received from one Vimal Bharati stating that the tenements which were certified as non-residential by the Executive Engineer were, in fact, residential tenements. In view thereof, the Chief Officer of the Repair Board called upon the Petitioners to furnish proof of use of the tenements as non-residential, which the Petitioners omitted and failed to do. According to the affidavit, no permission from the Municipal Corporation for change of the use of the premises has been submitted till date. It was in this background that the order came to be passed by the Chief Officer on 10 November
