3 It is pertinent to note that petitioner nos.3 and 4 never challenged the order dated 22.12.10 passed by the Deputy Collector (Enc./Rem) and the same has achieved finality. What the petitioner nos.3 and 4 have challenged, is the notice issued for implementation of the said order. The Slum Rehabilitation Scheme, sanctioned by the SRA, has already been completed by the developer and permanent rehab accommodation have been allotted to petitioner nos.3 and 4 in July, 2010. Occupation Certificate has also been granted to rehab building and the slum dwellers other than petitioner nos.3 and 4 have already shifted to the said building. The learned counsel for the petitioner nos.3 and 4 contends that they are entitled for premises admeasuring 269 sq.ft. according to the new policy and not for 225 sq.ft. , as allotted by the SRA. Developer obtained LOI on 20.2.2007, i.e., prior to 14.5.2008 on which date, new policy came into force. In the circumstances, it is not open for petitioner nos.3 and 4 to claim advantage of the new policy.
