Commencement of Statutes — Interpretation of Statutes Notes

Commencement of Statutes

Here is a real trap examiners love. A Central Act is assented to by the President on 26 January at 10.30 a.m. A man does the forbidden act at 9 a.m. the same day — an hour before the assent. Is he caught? Most students say “no, the Act was not yet in force at 9 a.m.” The law says otherwise: a statute comes into force from the first moment of the day it commences, not from the clock-time of assent. The 9 a.m. act is caught. One line of the General Clauses Act decides the whole problem.

What is commencement, and when does a statute come into force?

Commencement means the day on which a statute comes into operation — the moment it becomes binding law. Enactment (passing) and commencement are two different things: an Act may be passed today but commence months later.

There are three possible situations. Learn each:

The Act fixes its own date. Many Acts say “This Act shall come into force on such date as the Central Government may, by notification, appoint.” Until that notification, the Act — though passed — is not in force. The government may even bring different provisions into force on different dates.
The Act is silent. If a Central Act says nothing about commencement, Section 5 of the General Clauses Act, 1897 supplies the answer: it comes into force on the day it receives the assent of the President (for a Central Act) or the Governor/President (for a State Act).
The “whole day” rule. When an Act commences on a given day, it is treated as operative from the very first moment (12 midnight) of that day, not from the hour of assent. The law does not, as a rule, notice fractions of a day. So an act done earlier that same day, before the physical moment of assent, is still governed by the Act.

Who and where. Commencement rules bind everyone the Act applies to and operate throughout the territory to which the Act extends. The trigger (when) is the assent date, the notified date, or the whole day of commencement, depending on which of the three situations applies.

Section 5, General Clauses Act, 1897: “Where any Central Act is not expressed to come into operation on a particular day, then it shall come into operation on the day on which it receives the assent … of the President.”

In Simple Terms: A statute becomes law on its commencement day — the date it fixes, or (if silent) the day it is assented to. And it operates from the start of that whole day, so the clock-time of assent does not matter.

🧩 WORKED EXAMPLE — The 10.30 a.m. assent

Facts. A Central Act is assented to on 26 January at 10.30 a.m. and is silent on commencement. X does the prohibited act at 9 a.m. the same day.

Rule. Under s.5 GCA the Act commences on the day of assent (26 January); and by the whole-day rule it operates from the first moment of that day, the law ignoring fractions of a day.

Apply. Commencement is 26 January — the entire day. X’s act at 9 a.m. falls within 26 January, even though it was before the 10.30 a.m. assent.

Conclusion. X is governed by the Act. The clock-time of assent is a decoy; the Act reaches back to midnight of its commencement day.

Case Laws

A.K. Roy v Union of India (1982) — where an Act leaves commencement to government notification, the provision is not in force until the notification is issued; the power must be exercised, not withheld arbitrarily.
Union of India v Ganesh Das Bhojraj (2000) — a notification bringing a provision into force operates from the date of its publication in the Official Gazette.
