Executive modification power permits exemptions for SEZ laws, subject to parliamentary draft review and possible disapproval. The Central Government may, by notification, exempt or adapt most provisions of the SEZ Act and related Central Acts, rules or orders for a particular SEZ or class of SEZs, excluding sections 54 and 56 and excluding modifications affecting labour, trade union and related welfare matters; such notifications must be laid in draft before both Houses of Parliament for thirty days and may be disapproved or required to be modified by both Houses within the succeeding session.
