6A. Revision of rent. –
Notwithstanding anything contained in this Act, the standard rent, or, where no standard rent is fixed under the provisions of this Act in respect of any premises, the rent agreed upon between the landlord and the tenant, may be increased by ten per cent. every three years.
Section 6A of the Act cannot be said to be retrospective simply for the reason that if a party wants to immediately give effect to it, reliance is to be placed on antecedent to its passing. The provision does not create any liability for the past. The liability to increase the rent is only from future, i.e., after the statute came into force, Merely because it has to be seen that during the three years preceding the notice of the landlord to increase. the rent, there has been no increase in rent, if cannot be said that the provision becomes retrospective in its operation; National Co-operative Consumer Federation of India Ltd. v.
