It was said on behalf of the petitioners that even if the Authority was set up for providing housing accommodation to the people in different income groups (keeping in view their financial capacity/affordability) yet a statutory body like the Authority operating on 'no profit no, loss ' basis must have a scientifically prescribed formula for working out its price structure and that must be uniformly applied to all those who apply for flats and to whom they are allotted and such a statutory Authority cannot discriminate in working out the disposal price of the flats by including surcharge in respect of some MIG schemes within a certain specified period, a surcharge not authorised by law and not sanctioned by the Authority as a component of price and unknown to pricing of flats, while others similarly situated and similarly circumstanced and belonging to the same income group enjoyed the benefit cf getting flats at cost price and, therefore, petitioners have been accorded discriminatory treatment in the matter of price of flats allotted to them.
