then to examine whether OP is dominant in that relevant market or not. The Commission observes that the allegations in the instant case relate to allotment of two apartments by OP to the Informant in its housing project ‘‘Paras Tierra’ developed at Sector -137, Noida-Greater Noida Expressway, Noida. Thus, the relevant product in this case is residential apartment/ flat which is different from plot of land or commercial space. It may be noted that a plot of land or a commercial space cannot be considered as substitutable with a residential unit by the consumers because of the difference in the characteristics of the product, difference in price and intended use. Therefore, the Commission considers the market for “ the provision of services for development and sale of residential apartments/ flats” as the relevant product market in this case . With regard to delineation of the relevant geographic market, it is observed that the conditions of competition prevailing in the geographic region of Noida and Greater Noida are homogeneous and distinct from those prevailing in adjacent areas. Therefore, the relevant geographic market may be considered in this case as the geographic region of Noida and Greater Noida. Accordingly, the relevant market in this case may be considered as the market for ‘ provision of services for development and sale of residential apartments/ flats in Noida and Greater Noida’.
