When did the Constitution of India come into force?

The Governing Provision: Article 394

The commencement of the Constitution is governed by Article 394, which is itself a rather curious provision because it deals with the coming into force of the Constitution before the Constitution as a whole had actually come into force. Article 394 reads that "this article and Articles 5, 6, 7, 8, 9, 60, 324, 366, 367, 379, 380, 388, 391, 392 and 393 shall come into force at once, and the remaining provisions of this Constitution shall come into force on the twenty-sixth day of January, 1950, which day is referred to in this Constitution as the commencement of this Constitution". This drafting technique — bringing a small cluster of provisions into immediate force while postponing the rest — was a deliberate and practical device adopted by the framers to ensure that certain foundational and preparatory tasks could be completed before the full constitutional machinery was switched on.

Why Some Provisions Commenced Earlier

The provisions that commenced on 26th November 1949 were, by their very nature, ones that needed to operate before 26th January 1950 could arrive at all. Article 60 concerns the oath to be taken by the President, Article 324 establishes the Election Commission, and Articles 366 and 367 deal with definitions and interpretation, all of which had to be functional in advance so that the transition to the new constitutional order could be organised smoothly. Similarly, Articles 5 to 9, dealing with citizenship, needed to be settled early so that the citizenry of the new Republic was defined before the Republic itself formally began. Article 393 gave the Constitution its short title, "the Constitution of India," and this too was brought into force at once.

Significance of 26th January 1950

The date 26th January 1950 was chosen deliberately, not arbitrarily, as it commemorated the Purna Swaraj declaration of complete independence proclaimed by the Indian National Congress in 1930, and this date is expressly referred to in the Preamble itself. From this date, described in Article 394 as "the commencement of this Constitution," the remaining and overwhelming bulk of the Constitution's 395 original Articles became binding law, and India transformed from a Dominion under the Government of India Act, 1935 into a Sovereign Democratic Republic.

Judicial Treatment of Commencement

The courts have had to work out several consequences flowing from this staggered commencement, particularly in relation to pre-existing laws and rights. In Keshavan Madhava Menon v. State of Bombay, the Supreme Court held that Article 13(1), which renders pre-Constitution laws void to the extent of inconsistency with Fundamental Rights, operates only prospectively from the date of commencement and does not wipe out liabilities or proceedings that had already validly arisen before 26th January 1950. Applying this reasoning, the Court held that a person being prosecuted under a law before the Constitution came into force could not escape that prosecution merely because the law later became inconsistent with a Fundamental Right, since the offence itself had been committed before the Constitution's commencement.

This principle of prospective operation also gave birth to the doctrine of eclipse, developed by the Supreme Court in Bhikaji Narain Dhakras v. State of Madhya Pradesh. A law enacted in 1948 had become inconsistent with a Fundamental Right upon the Constitution's commencement in 1950, and the Court held that such a pre-Constitution law is not wiped out altogether but merely rendered dormant or "eclipsed"; if the relevant Fundamental Right is later amended to remove the inconsistency, the law is automatically revived without need for re-enactment, precisely because it was valid when made and only became inoperative from the date the Constitution commenced. Article 372 correspondingly ensured continuity by providing that all laws in force in India immediately before the commencement of the Constitution would continue in force until altered, repealed, or amended by a competent legislature, thereby preventing a legal vacuum on 26th January 1950.

The staggered commencement scheme under Article 394 thus reflects the framers' practical wisdom: rather than switching on an entirely untested constitutional machine in one instant, they activated its essential preparatory gears first, ensuring that the Republic born on 26th January 1950 could function from its very first day without administrative or legal disruption.
