New Delhi: The Board of Approvals today cleared 28 SEZ proposals, including Mukesh Ambani''s Navi Mumbai project. The board gave formal approval to 21 SEZs and ''in-principle'' approvals to seven proposals.

On 6 July, the Parliamentary committee on SEZs had said that no further SEZs should be notified unless the existing law was amended to incorporate the changes related to land acquisitions.

The committee had also said that there should not be transfer of ownership, and all land for SEZs should be taken on lease by developers.

The committee, headed by Murli Manohar Joshi, had specified that the maximum area for multi-product SEZs should not exceed 2,000 hectares, if the land acquired is cultivable. However, an empowered group of ministers (GoM), had fixed the land ceiling limit at 5,000 hectares.
