Sections 1 and 3 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Section 1 gives the Act its name, says where it applies and lets the Central Government choose when it starts. Section 3 then says the Act prevails over any inconsistent provision in another law. Together they answer two practical questions: from when does the Act bind you, and what happens if another law says something different?
The Act is called the Legal Metrology Act, 2009 and extends to the whole of India. It came into force on a date fixed by notification, and the official text records 1 March 2011 (S.O. 1(E) dated 31 December 2010). Section 3 makes the Act prevail over inconsistent provisions in any other enactment or in any instrument made under another enactment. Neither section is amended by the Jan Vishwas Acts of 2023 or 2026.
Section 1(1): short title
The Act "may be called the Legal Metrology Act, 2009". It is Act 1 of 2010, and the date printed under the title in the official text is 13 January 2010. The long title tells you what the law is for: to establish and enforce standards of weights and measures, to regulate trade and commerce in weights, measures and other goods sold or distributed by weight, measure or number, and for connected matters. That last idea is why the Act reaches packaged goods and their labels, not only scales and measuring jars. For a plain-language overview, see our introduction to the Legal Metrology Act, 2009.
Section 1(2): extent
Sub-section (2) says the Act "extends to the whole of India". It is a Central Act, so it applies in every State and Union territory. The Act divides administration between the Centre and the States (Director and Central officers under section 13, Controller and State officers under section 14), but the substantive law is the same everywhere. States make their own rules under section 53 for matters such as licence forms and fees, which is why procedure can differ by State even though the Act does not.
Section 1(3): commencement by notification
Sub-section (3) does not fix a date. The Act "shall come into force on such date as the Central Government may, by notification in the Official Gazette, appoint and different dates may be appointed for different provisions of this Act."
Two points follow:
- The Central Government chose the date. The footnote in the official text reads: "1st March, 2011, vide notification No. S.O. 1(E), dated 31st December, 2010". That is the date recorded for the Act's commencement.
- The power to appoint different dates for different provisions exists, so the footnote alone does not prove that every section started on one day. If a dispute turns on the exact start date of a particular section, check the notification itself; the text we have does not reproduce it.
| Instrument | What the source says about its start |
|---|---|
| Legal Metrology Act, 2009 | Section 1(3): date to be appointed by notification; footnote records 1 March 2011 (S.O. 1(E), 31 December 2010) |
| Legal Metrology (General) Rules, 2011 | Rule 1(2): come into force on 1 April 2011 (notified as G.S.R. 11(E), 7 February 2011) |
| Legal Metrology (Packaged Commodities) Rules, 2011 | Rule 1(2): come into force on 1 April 2011 (notified as G.S.R. 202(E), 7 March 2011) |
Notice the gap: the Act started on 1 March 2011, the Rules on 1 April 2011. Read each instrument's own commencement clause when you need the operative date for a specific obligation, and note that the General Rules were notified on 7 February 2011, before the Act's recorded start, while each set of Rules takes effect only from its own rule 1(2) date. If you need help fixing the right date for a particular notice or prosecution, a legal consultation can trace the notification for you.
Section 3: the Act overrides inconsistent law
Section 3 reads: "The provisions of this Act shall have effect notwithstanding anything inconsistent therewith contained in any enactment other than this Act or in any instrument having effect by virtue of any enactment other than this Act."
Break it into parts:
- "Notwithstanding anything inconsistent": the override works only where there is an inconsistency. If another law can be followed together with the Act, both apply.
- "Any enactment other than this Act": Central and State Acts.
- "Any instrument having effect by virtue of any enactment": rules, regulations, orders and notifications made under other laws.
The section protects the Act's core content: standard units, standard weights and measures, verification, declarations on pre-packaged commodities and the penalties. A State law or a trade regulation cannot, for example, allow quotation of a price in a non-standard unit if section 11 forbids it.
What section 3 does not do
- It does not cancel other laws on the same goods. A packaged food must still meet food law; a cosmetic must still meet drugs law. Section 3 only resolves conflicts.
- It does not itself defer to other laws. Where the Legal Metrology (Packaged Commodities) Rules, 2011 step aside for another law, the Rules say so. For example, rule 6(1) provides in an Explanation that for food packages the Food Safety and Standards Act, 2006 and its rules apply instead of the name-and-address clause, and a proviso makes the same move for the date declaration. The Packaged Commodities Rules are quoted here as amended up to March 2022; check later amendments.
Examples
Example 1: start date. A dealer is challenged over a verification lapse said to have occurred in February 2011. The Act's footnote shows a start on 1 March 2011, so the first step is to check whether the provision relied on had begun by that date.
Example 2: conflict. A local notification requires goods to be quoted in a unit that the Act does not treat as a standard unit. To the extent it is inconsistent with the Act's standard-unit provisions, section 3 makes the Act prevail.
Common mistakes
- Treating 1 April 2011 as the Act's start. That is the date for the two sets of Rules; the Act's footnote records 1 March 2011.
- Reading section 3 as cancelling every other law that touches packaged goods. It only overrides inconsistent provisions.
- Assuming a State can relax an Act-level duty by its own rules. State rules under section 53 fill in procedure; they sit below the Act.
