New Delhi: Special economic zones (SEZ) after getting the green signal from the group of ministers are being termed as unconstitutional by legal experts.

Articles 243 G and 243 Z (e) and Z (d) in the constitution introduced in 1992 will be stumbling blocks for the smooth passage of the SEZs despite 117 of them being cleared by the Centre.

Legal experts said the Articles require each village community to make its development plan which would be incorporated in the district plan. However, district planning committees or the State Finance Commissions are not in place in most states except in Kerala.

"Till such time as a village or district committee with specific development plans is in place, the SEZs cannot be thrust on the country," say the activists who are planning a countrywide agitation against SEZs from April 9.
