Supreme Court of India (V. R. Krishna Iyer, D. A. Desai and A. P. Sen, JJ.; judgment delivered by Krishna Iyer, J.), Civil Appeal No. 1526 of 1978, decided September 22, 1978 — appeal by special leave from the judgment/order dated 9-8-1977 of the Himachal Pradesh High Court in Civil Revision No. 68 of 1976 — East Punjab Urban Rent Restriction Act, 1949, as applied to Himachal Pradesh, S. 13(2)(ii)(b) ('used the building ... for a purpose other than that for which it was leased'). A harijan cobbler-tenant of a portion of a shop in Ram Bazar/Bazaar, Simla (annual rent Rs. 300/-), who cooked his food and stayed at night in the rear portion of the leased shop, was proceeded against for eviction on the ground of diversion of user; the lease deed (Ex. P. 1) disclosed no purpose, yet the High Court in revision restored the Rent Controller's eviction order on the inference that letting of a shop must be for a commercial purpose. Held: statutory construction cannot be divorced from the social setting; welfare legislation protecting tenants must be read in a Third World perspective, doubts being tested by the Gandhian talisman (Moti Ram applied); the intention of the parties is garnered from the social milieu, and where the lease does not spell out the purpose it cannot be held exclusively commercial or incompatible with residential use of a portion; incidental staying, cooking and eating by a petty tradesman-tenant is not a diversion — a different 'purpose' connotes majuscule change in mode of enjoyment, not minor variations; oral permission cannot replace the statutory written consent, but the landlord's long acquiescence reinforced the two-fold-purpose reading; consequently S. 13(2)(ii) was not attracted. The later amendment defining 'non-residential building' to cover partly business/partly residence use was noted as legislative approval of the de facto position, its applicability to pending proceedings being expressly left uninvestigated. Appeal allowed with costs; tenant not to be ejected; trial court directed to restitute possession under S. 144 C.P.C. within one month, ignoring any other tenant inducted by the landlord.
