If, as contended for on behalf of the respondents, section 11 of the Act were to be construed as entitling a landlord to apply for eviction of a tenant on the ground of irregular payment of rent amounting to ' non payment ' of rent and as empowering the Controller to determine as to whether irregular payment of rent amounts to non payment of rent within the meaning of sub section (1)of section 11, and subsection (3) of section 18 were to be construed as making the decision of the Controller on this question of law a final one, it will appear that not only this Act will have conferred a right upon the landlord very much in excess of the right that he enjoys under the ordinary law in the matter of determination of tenancies, but that it will have conferred very much larger power on the Controller than that possessed by the Civil Courts under the ordinary law in the matter of passing decrees for eviction of tenants.
