Awaiting reports from the Maharashtra government and developers, the Board of Approval today deferred decision on Mukesh Ambani-promoted Navi Mumbai SEZ but approved the Tata's Gopalpur SEZ in Orissa.Commerce Secretary and BoA Chairman G K Pillai told reporters that the government had received a report from the Revenue Department on the Navi Mumbai project, but was awaiting views from the state government and the developers."We wanted to get comments from the developers and the state government on the report of the Revenue Department," Pillai said.The Revenue Department wanted to know whether arrangements had been made for plugging possible revenue leakages because of a road passing through the zone being promoted by Ambani and his close aide Anand Jain.The 1,173 hectare Gopalpur SEZ, promoted by Tatas in Ganjam district of Orissa, was deferred in September last year as the BoA wanted to ensure that it posed no problem to a security facility nearby."
