5.2. The Act was enacted to provide a speedy machinery for eviction of unauthorised occupants of public premises by way of summary eviction. Section 5 of the Act provides for eviction of unauthorised occupation. Section 7 of the Act provides for recovery of rent and damages in respect of public premises from the persons who had unauthorisedly occupied the same, by appointing Estate Officers, who have been given power, after necessary enquiry to pass orders of eviction of such unauthorised occupants. The Estate Officer has also been given powers to remove and to order demolition of unauthorised constructions. Since the encroachment of the public premises are considered as a public menace which are required to be discouraged in the larger public interest, as no one has got the right to occupy or encroach the public premises, the Estate Officer is empowered to exercise his power of enquiry by adopting a summary eviction proceedings giving notice within seven days to the respective occupants, which is mandatory, not merely directory in character, as the failure to make an effective reply to the notice may result in loss of occupation of the premises."
