Doctrine of Eclipse

Meaning and Definition #

The Doctrine of Eclipse is a judicially evolved principle used to explain what happens when a pre-Constitution law becomes inconsistent with Fundamental Rights (Part III) after 26 January 1950.

If a law “in force” before the Constitution violates any Fundamental Right, it is not treated as wiped out completely. Instead, it becomes unenforceable (inoperative) only to the extent of the inconsistency. The law is said to be “eclipsed” by the Fundamental Right—like a shadow falling on it—so it continues to exist on the statute book, but cannot be enforced while the inconsistency remains.

If later the Constitution is amended (or the relevant Fundamental Right is modified) such that the inconsistency disappears, the eclipse is removed and the law revives automatically without re-enactment.

Constitutional / Statutory Basis: Article 13(1) #

The doctrine is anchored in Article 13(1):

All laws in force immediately before the commencement of the Constitution, insofar as they are inconsistent with Part III, shall, to the extent of such inconsistency, be void.

Two phrases are key:

• “laws in force… before commencement” → points to pre-Constitution laws
• “to the extent of such inconsistency” → supports partial and limited inoperativeness, not total destruction

So, under Article 13(1), the law becomes “void” only in its operation, not necessarily void in existence.

Where It Applies (Scope) #

Applies to:

1. Pre-constitutional laws (laws existing before 26 January 1950) that conflict with Part III.

Does NOT apply to:
2. Post-constitutional laws (made after 26 January 1950). These are hit by Article 13(2) and are void ab initio if they take away or abridge Fundamental Rights.

Core Features #

1. Dormant, not dead: The law remains on the statute book but is unenforceable to the extent of inconsistency.
2. Partial operation: Only the inconsistent part is eclipsed (linked conceptually to severability).
3. Automatic revival: If the constitutional bar is removed (e.g., by amendment), the law revives without fresh legislation.
4. Right-specific nuance: If the inconsistency is with a Fundamental Right available only to a certain class (e.g., Article 19 for citizens), the eclipsed law may still operate against non-citizens.

Case Laws #

Post-Constitution laws violating Fundamental Rights fall under Article 13(2) and are void ab initio. #

1) Bhikaji Narain Dhakras v. State of Madhya Pradesh (1955) #

Facts #

• The petitioners were stage-carriage operators running buses on permits under the Motor Vehicles Act, 1939.
• In the then Central Provinces & Berar, the Motor Vehicles Act, 1939 (as applicable locally) was amended by the C.P. & Berar Motor Vehicles (Amendment) Act, 1947 (referred to in the judgment as Act III of 1948), conferring extensive powers on the Provincial/State Government, including the power to create a monopoly in its favour in motor transport.
• Under the amended s. 43(1)(iv) the Government could declare that it will engage in the business of road transport service; under the amended scheme it could also cancel permits (subject to conditions).
• After the Constitution (26 Jan 1950), such monopoly/cancellation powers were attacked as violating Article 19(1)(g) (citizens’ right to trade/business).

Issue #

Whether a pre-Constitution law that became inconsistent with Article 19(1)(g) on 26-1-1950 is:

• “dead/void completely” and needs re-enactment, or
• merely inoperative to the extent of inconsistency (i.e., eclipsed) and capable of operating again if the inconsistency is removed.

Held #

• The Court explained the true effect of Article 13(1): it renders an inconsistent pre-Constitution law “inoperative to the extent of the inconsistency”—it is “overshadowed” and “remains dormant but is not dead.”
• After the Constitution (First Amendment) Act, 1951, Article 19(6) was amended so that existing laws relating to State monopoly could be protected; once this amendment removed the inconsistency, the impugned pre-Constitution Act began to operate again from the date of the amendment.
• The Court uses the classic eclipse language: between 26-1-1950 and 18-6-1951 the impugned law could not restrict a citizen’s Article 19(1)(g) right; the law was “eclipsed for the time being”, and the First Amendment “removed the shadow.”

Principle #

A pre-constitutional law inconsistent with a Fundamental Right is not wiped out; under Article 13(1) it becomes temporarily inoperative (eclipsed) to the extent of inconsistency, and revives automatically once the constitutional inconsistency is removed (e.g., by amendment).

2) Deep Chand v. State of Uttar Pradesh (1959) #

Facts #

• The appellants were private stage-carriage operators holding permits under the Motor Vehicles Act, 1939, operating on routes in U.P.
• The U.P. Legislature enacted the U.P. Transport Service (Development) Act, 1955, enabling State nationalisation/exclusive operation of certain road transport services through schemes/notifications, affecting private operators’ routes and permits.
• The operators challenged the post-Constitution Act, raising (among other grounds) the Fundamental Rights attack and the State’s attempt to rely on the eclipse-type reasoning to sustain what was otherwise invalid. The judgment expressly frames the doctrine point: a law violating Part III after 26-1-1950 is void ab initio, and doctrine of eclipse is only for pre-Constitution laws.

Issue #

Can the Doctrine of Eclipse apply to a post-Constitution law which violates Fundamental Rights, so that it lies “dormant” and could revive later?

Held #

• The Court states the core rule: where a post-Constitution law is in derogation of Part III, it is “void ab initio” (wholly or to the extent of contravention), and the doctrine of eclipse can be invoked only in the limited Article 13(1) situation (pre-Constitution laws).
• It then makes the doctrine conclusion explicit: “There is no scope for applying the doctrine of eclipse to a case where the law is void ab initio…”
• Therefore, a post-1950 law offending Part III is a nullity from inception under Article 13(2) and cannot be treated as merely “shadowed” and later revived.

Principle reaffirmed #

Eclipse is confined to Article 13(1) (pre-Constitution laws).
A post-Constitution law infringing Fundamental Rights is struck by Article 13(2) as void ab initio, leaving no room for “dormancy and/or revival.”

Conclusion #

The Doctrine of Eclipse ensures constitutional supremacy without unnecessary legislative chaos. It treats pre-Constitution inconsistent laws as temporarily inoperative, not obliterated—allowing them to revive if the constitutional barrier is removed. However, post-Constitution laws violating Fundamental Rights are void ab initio and cannot be saved by this doctrine.
