Parliament Legislating for States by Consent

Legislation by consent refers to Article 252, which allows Parliament to make a law on a State List subject when the legislatures of two or more States themselves ask for it — and lets any other State later opt in to the same law by passing its own adoption resolution. Unlike Articles 249 and 250, this route depends entirely on the States' own initiative rather than a Rajya Sabha resolution or a national emergency.

What Article 252 Provides

Article 252(1) applies to "matters with respect to which Parliament has no power to make laws for the States except as provided in articles 249 and 250" — that is, ordinary State List subjects outside any emergency or national-interest override. It states that if it appears to the legislatures of two or more States that a particular matter should be regulated by Parliament instead, and if resolutions to that effect are passed by all the Houses of the Legislatures of those States, "it shall be lawful for Parliament to pass an Act for regulating that matter accordingly."

Crucially, the resulting Act does not stop at the States that asked for it. It automatically applies to those requesting States, and it can later be extended to "any other State by which it is adopted afterwards by resolution passed in that behalf" by that State's own Legislature. In effect, Article 252 offers a standing template: once Parliament legislates for the requesting States, any other State can simply adopt the same law rather than re-legislating from scratch.

Who Controls Amendment and Repeal

Article 252(2) settles an important point about ownership of the law once it exists: an Act passed under this Article "may be amended or repealed by an Act of Parliament passed or adopted in like manner but shall not, as respects any State to which it applies, be amended or repealed by an Act of the Legislature of that State." Once States hand a subject over to Parliament this way, they cannot unilaterally take it back by their own legislation — only Parliament (through a further Article 252 process) can amend or repeal the resulting law for the States it covers.

Why States Use This Route

The practical value of Article 252 is uniformity without a constitutional amendment. If several States want identical regulation on a State List subject — say, a regulatory or licensing regime — asking Parliament to legislate once, rather than each State separately, avoids duplicated, potentially inconsistent, State-level drafting. Any State that did not join the original request can adopt the resulting Union law later if it comes to see the same benefit, without having to draft its own version.

Feature	Detail
Who initiates	Two or more State Legislatures, by resolution passed in all Houses
Subject covered	State List matter outside Articles 249/250
Who can join later	Any other State, by its own adoption resolution
Who can amend/repeal	Only Parliament — not the State Legislature, once the State is covered

Where This Fits Among Parliament's Other Routes into the State List

Article 252 stands beside Article 249 (national interest, Rajya Sabha resolution), Article 250 (national emergency), and Article 253 (implementing international agreements) as one of the constitutionally recognised ways Parliament can step into the State List. What distinguishes it is direction of initiative: here the States themselves ask Parliament in, rather than Parliament acting on a national or emergency ground.

UPSC Relevance

Prelims

• Minimum number of States needed to trigger Article 252 (two) and the requirement that resolutions be passed by all Houses of those States' Legislatures.
• The adoption mechanism — a State not originally party can later adopt the Act by its own resolution — is a distinguishing, testable feature.
• Note that only Parliament, not the concerned State Legislature, can amend or repeal the resulting Act for that State.

Mains

• Useful in GS2 answers on cooperative federalism, since Article 252 is a State-initiated (rather than Centre-imposed) route into Union legislation on a State subject.
• Can be contrasted with Articles 249/250/253 to build a complete picture of Parliament's exceptional powers over the State List for federalism-themed questions.

FAQ

Q1. How many States must request Parliament to legislate under Article 252? At least two States, through resolutions passed by all the Houses of their respective Legislatures.

Q2. Does an Article 252 law automatically apply to every State? No. It applies only to the States that requested it, plus any other State that later adopts it by its own resolution.

Q3. Can a State amend or repeal an Article 252 law on its own? No. Once a State is covered by such an Act, only Parliament can amend or repeal it for that State; the State Legislature cannot.

Q4. How is Article 252 different from Article 249? Article 249 is triggered by a Rajya Sabha resolution in the national interest; Article 252 is triggered by the requesting States' own legislatures, with no Rajya Sabha role.

Q5. What kind of subjects does Article 252 cover? Ordinary State List matters that are not already covered by the national-interest power (Article 249) or the emergency power (Article 250).

Quick Revision

• Article 252 — two or more States request Parliament to legislate on a State subject; Parliament may then pass the Act.
• Other States can adopt the resulting Act later by their own resolution.
• Only Parliament, not the State Legislature, can amend or repeal such an Act for a covered State.
• Initiative comes from the States, unlike Article 249 (Rajya Sabha) or Article 250 (Emergency).
