Part IV of the Application and the demand notice dated 07.12.2018, is 01.07.2011 to 30.06.2016, being the dates of invoices. The invoices produced by the OC with the Application indicate that these are in respect of security services provided at various sites of the CD such as Bhoiwada, Byculla, Navi Mumbai, etc. However, in the demand notice, the OC has claimed payments in respect of different sites such as Dhule, Crown Mill, Malad, Sales Bhoiwada, Airoli, Koperkhairne, Powai, Worli, Saat Raasta, Rehab Worli, Vadodara, Kalamboli, Byculla, Seawood and Pune.

Hence, we hold that in
