hand, we find that according to Section 11(9) of the Act, where the tenancy is for a specified period agreed upon between the landlord and the tenant, the landlord shall not be entitled to apply to the Rent Control Court for eviction of the tenant before the expiry of such period. In the above view, we are of the opinion that, the Legislature was so conscious to omit such a bar against institution of rent control petition seeking fixation of fair rent even if there is an agreement between the landlord and the tenant fixing the rent with provision for periodical enhancement. The absence of such a statutory bar gives rise to an inference that the Legislature has consciously permitted the landlord to approach the Rent Control Court to get the fair rent determined, notwithstanding the stipulation regarding periodical enhancement in the lease agreement. Therefore, it can be concluded that an agreement fixing the rent with periodical enhancement, at a specified rate, between the landlord and tenant, will not preclude the landlord from instituting a rent control petition invoking Section 5(1) of the Act, for fixation of fair rent.'
