Section 49 SEZ Act: Power to Modify Provisions

Updated 11 October 2026 · Fact-checked

Section 49 of the SEZ Act, 2005 lets the Central Government, by notification, direct that any provision of the SEZ Act (other than sections 54 to 56) or of any other Central Act does not apply to SEZs, or applies only with exceptions, modifications and adaptations. Labour matters are protected, and a draft must be laid before Parliament for thirty days.

Understand Section 49: Power to Modify Provisions in SEZs

An SEZ is meant to work with fewer procedural hurdles than the rest of India. But the SEZ Act cannot list every change needed in every other law. Section 49 solves this. It gives the Central Government a flexible tool: a notification that switches off or adapts a legal provision for SEZs.

The power has a wide reach. The notification can cover any provision of the SEZ Act itself (except sections 54 to 56), or any other Central Act, and the rules, regulations, notifications, orders or directions made under it. The one carve-out is the provisions relating to the making of rules or regulations.

The notification can work in two ways. Under clause (a), a provision shall not apply to one SEZ, a class of SEZs, or all SEZs. Under clause (b), it applies only with exceptions, modifications and adaptation as the notification specifies. So the Government can exempt fully or tailor the law.

There are two safeguards. First, the proviso says the section does not apply to modifications on trade unions, industrial and labour disputes, welfare of labour including conditions of work, provident funds, employers' liability, workmen's compensation, invalidity and old age pensions, and maternity benefits. Labour protection stays intact in SEZs. Second, sub-section (2) requires a copy of every proposed notification to be laid in draft before each House of Parliament for a total of thirty days, in one session or in successive sessions.

If, before the end of the session following the sessions in which the draft was laid, both Houses agree in disapproving it, the notification is not issued. If both agree on a modification, it is issued only in that modified form. Link this with section 51, which gives the SEZ Act overriding effect over inconsistent laws, and section 53, which treats an SEZ as outside the customs territory of India for authorised operations.

Key rules to remember

Who exercises the power: Central Government, by notification; Not the State Government and not the Board. States have a separate power under section 50 for State taxes, levies and duties.
Scope of the power: SEZ Act (except sections 54 to 56) + any other Central Act + rules, regulations, notifications, orders, directions; Provisions relating to making of rules or regulations are excluded.
Two kinds of direction: (a) shall not apply; (b) shall apply only with exceptions, modification and adaptation; Either can be for one SEZ, a class of SEZs or all SEZs.
Labour proviso: No modification on trade unions, labour disputes, labour welfare, provident funds, employers' liability, workmen's compensation, pensions, maternity benefits; Labour laws continue to apply in SEZs.
Parliamentary control: Draft laid before each House for a total of 30 days; Both Houses agreeing to disapprove stops the notification; agreeing to a modification means it is issued only in that form.

How to solve Section 49: Power to Modify Provisions in SEZs questions

Use this method for any question on the power to modify laws for SEZs.

1Identify who is acting. Section 49 is a Central Government power exercised by notification.
2Check what is being modified. It must be the SEZ Act (not sections 54 to 56) or another Central Act or its rules, notifications or orders. A State law is not covered.
3Decide which limb applies: non-application under clause (a) or application with modification under clause (b), and for which SEZs.
4Test the labour proviso. If the change touches trade unions, labour disputes, labour welfare, provident fund, workmen's compensation, pensions or maternity benefits, the power cannot be used.
5Check the procedure: the draft must be laid before both Houses for thirty days.
6Apply the outcome rule: disapproval by both Houses means no notification; agreed modification means issue in modified form.
7Write a clear conclusion in one line, citing section 49, and link to section 51 or 53 if the question involves overriding effect or customs territory.

Quickest way: Four-point check for Section 49

When to use it: Use for MCQs and short case questions where you must say whether a notification under section 49 is valid.

Who: Central Government only.
What: SEZ Act except sections 54 to 56, or other Central Act and rules under it.
Not allowed: labour matters in the proviso.
Process: draft laid for thirty days; both Houses can block or modify.

Common mistakes in Section 49: Power to Modify Provisions in SEZs

Saying the State Government can modify laws under section 49.
Students mix it up with section 50, which deals with State exemptions.
Fix: Section 49 is Central Government. Section 50 lets the State notify policies and laws for exemption from State taxes, levies and duties.
Stating that all sections of the SEZ Act can be modified.
The words 'any provision' are read without the bracket.
Fix: Sections 54 to 56 are excluded. Remember the bracket.
Forgetting the labour proviso.
Students focus on customs and tax benefits only.
Fix: Remember labour matters: unions, disputes, welfare, PF, employers' liability, workmen's compensation, pensions, maternity benefits cannot be modified.
Saying Parliament must approve the notification before it is issued.
Laying a draft is confused with positive approval.
Fix: The draft is laid for thirty days. It is stopped or modified only if both Houses agree to disapprove or modify.
Confusing section 49 with section 52 on Chapter XA of the Customs Act.
Both relate to customs law in SEZs.
Fix: Section 49 is a general notification power. Section 52 says Chapter XA of the Customs Act, 1962 and the SEZ Rules and Customs Procedure Regulations of 2003 stop applying to SEZs from a date the Central Government notifies.
Thinking one notification must cover all SEZs.
Students overlook the words 'class of Special Economic Zones'.
Fix: The notification can target one SEZ, a class of SEZs or all.

Worked examples

Example 1

The Central Government proposes a notification under section 49 stating that a specified provision of the Customs Act, 1962 shall apply to SEZs only with certain adaptations. (a) Is this within section 49? (b) What procedure must be followed before it is issued?

Show the solution

The Customs Act, 1962 is a Central Act, so it falls within the power.
Applying a provision only with adaptations is clause (b): application with exceptions, modification and adaptation.
The notification can be for all SEZs or a class of SEZs.
Procedure: a copy of the proposed notification must be laid in draft before each House of Parliament for a total of thirty days, in one session or in successive sessions.
If both Houses agree in disapproving it before the end of the session following, it is not issued. If both agree on a modification, it is issued only in that modified form.

Answer: Yes, it is within section 49(1)(b). The draft must be laid before both Houses for thirty days; it can be stopped or modified only by agreement of both Houses.

Example 2

A draft notification proposes that, for all SEZs, provisions of a Central Act on provident funds shall not apply to employees working in SEZs. Can the Central Government issue it under section 49?

Show the solution

Section 49(1) allows non-application of Central Act provisions to SEZs.
But the proviso states that the section does not apply to modifications relating to provident funds, among other labour matters.
So the matter falls in the protected labour category.
The Central Government therefore cannot use section 49 for this purpose, even though the draft is laid before Parliament.

Answer: No. The proviso to section 49(1) bars modification on matters including provident funds, so the notification cannot be issued under this section.

Exam tips

Learn the exact exclusion: sections 54 to 56 of the SEZ Act cannot be modified under section 49.
Memorise the labour list in the proviso; MCQs often test one item from it.
Distinguish section 49 (Central, modify laws), section 50 (State, State tax exemption), section 51 (overriding effect) and section 52 (Chapter XA of Customs Act).
In case questions, always mention the thirty-day laying of the draft before both Houses.
Write short: who, what, limit, procedure, conclusion.
