Per Dharmadhikari, J :-

These petitions are placed before the Full Bench after a detailed order was passed in W.P.No.1326 of 2007 on 27th July, 2007.

2. The Maharashtra Slum Areas (Improvement, Clearance and Re-development) Act, 1971, (hereinafter referred to as "Slum Act" for short) came to be extensively amended in 1996-97 and 2001, introducing Chapter I-A therein. That Chapter is entitled "Slum Rehabilitation Scheme". Under that Chapter falls Section 3A. This provision is inserted with a view to establish a Slum Rehabilitation Authority (S.R.A. for short) for implementing Slum Rehabilitation Scheme. After this Chapter was introduced in the Slum Act and such Authority became functional for Brihanmumbai and its suburbs, that the S.R.A. decided to undertake and implement several rehabilitation schemes. The State took notice of proliferation of Slums on public lands and properties. Therefore, it decided to confer wide powers on the S.R.A. so that the public lands are cleared by S.R.A. acting in coordination with the local authorities. For that purpose, the State Government made appropriate amendments and inserted provisions in the planning and local laws. Insofar as, Mumbai is concerned, S.R.A. was put in charge of permitting developments on lands, which had large slum pockets. Lands were of private/public ownership. Therefore, after amending Maharashtra Regional and Town Planning Act (M.R.T.P. Act) for short, the Development Control Regulations for Brihanmumbai (D.C. Rules 1991) were also amended. These Development Control Regulations are traceable to section 22(m) of the M.R.T.P. Act, 1966. For individual development to be controlled, monitored and regulated as also restricted, development control rules were made and they are traceable to the Development Plan itself.

3. One of the Regulations in the set of Regulations, to control development in Mumbai, pertains to Floor Space Index and its computation (F.S.I). While, computing the permissible F.S.I. for development of the lands/property, incentives were offered by the State and Local Body (Brihanmumbai Municipal Corporation) to Developers and Builders. An obligation was cast upon them as also the owners of these private lands to rehabilitate the slum dwellers at the same site as far as possible and after discharging this obligation to develop the plot/land. The incentive was increased F.S.I. or appropriate adjustments in computing permissible outer limit. At the same time, the slum pockets were also offered incentive inasmuch as persons residing in slums were permitted to organise themselves into Cooperative Housing Societies and such Cooperative Societies were further permitted to come forward with a proposal for development of the land, on which slums are situated or located, either by societies themselves or an outside Agency and incentives were offered for the same as well.

4. The underlying object for the above being clearance of the lands by removal of the slums and dilapidated structures. It is now a well known fact of which judicial notice has been taken repeatedly, that large scale encroachment takes place as far as Government properties and lands are concerned. The Government and its instrumentalities and agencies are unable to control encroachment, illegal squatting and unauthorised development on its lands as the political will and strength is lacking. The slum pockets being Vote Banks, preventive or prohibitory measures are not initiated at right time. The number of encroachers and squatters on lands, roads and pavements have increased and one can witness the same. Once the incentives were offered as above and regulatory and rehabilitation measures and schemes were mooted number of disputes and differences between the slum dwellers/encroachers and the local authority and appropriate agencies have arisen which are consuming valuable time of this Court. In such disputes, the acts and omissions of the Authorities and Agencies are highlighted. The State and t
