Legal Metrology: formula sheet

Key formulas

Legal metrology (s 2(g))

Units + methods + instruments of weighment and measurement, with mandatory technical and legal requirements, to ensure public guarantee of security and accuracy

Use this to state the objective of the Act.

Pre-packaged commodity (s 2(l))

Packed without the purchaser being present + any package, sealed or not + pre-determined quantity

All three elements must be present. A sealed package is not required.

Weight or measure (s 2(w))

Weight or measure specified by or under the Act + weighing or measuring instrument

Instruments are included in the definition.

Legal metrology officer (s 2(h))

Additional/Joint/Deputy/Assistant Director or Controller + Inspector, appointed under sections 13 and 14

The Director and Controller are not in this list; they are defined in s 2(c) and 2(a).

Extent and commencement (s 1)

Whole of India; in force 1 March 2011

Commencement was by notification; different dates could be set for different provisions.

Standard units (s 11)

No quotation, price list, invoice, advertisement, net quantity or dimension except in standard units; not applicable to export

The exemption in s 11(2) covers export of goods, things or service.

Metric basis of units

Every unit = metric system based on the international system of units (s. 4)

No non-metric unit can be used as a legal unit of weight or measure.

Seven base units (s. 5)

Length: metre | Mass: kilogram | Time: second | Electric current: ampere | Temperature: kelvin | Luminous intensity: candela | Amount of substance: mole

Learn the pairs in this order. Examiners ask for the list.

Standard weight or measure (s. 8)

Conforms to standard unit + conforms to applicable s. 7 provisions = standard weight or measure

No manufacture or import of non-conforming ones, except for exclusive export or scientific research.

Valid standard (s. 9)

Reference / secondary / working standard valid only if verified and stamped

Without verification and stamping it is not deemed a valid standard.

Approval of model required BEFORE manufacture or import

Two provisos: exemptions for certain items, and approval of models approved abroad.

Penalty for alteration (s. 26)

Fine up to ₹50,000; repeat offence: imprisonment 6 months to 1 year, or fine, or both

Duty to verify

Possession/custody/control + likely use in transaction or protection → verify BEFORE use (Section 24(1))

Verification is at the place and hours the Controller specifies, on payment of the prescribed fee.

Test Centre route

Central Govt prescribes kinds → verification through Government approved Test Centre (Section 24(2)-(4))

The Central or State Government notifies the centre; it engages qualified persons and collects the prescribed fee.

Public servant and good faith (section 13(5) and (6))

Director, Controller and authorised officers = public servants; no suit, prosecution or legal proceeding for acts done in good faith

The text refers to section 21 of the Indian Penal Code. Mention it only as the Act's wording.

Inspection and seizure (section 15)

Reason to believe (written information, personal knowledge or otherwise) → enter at reasonable time, search, inspect, seize, require documents

Covers obstructing the officer's powers or functions, and obstructing entry into premises for inspection and verification.

Compounding (section 48(1))

Listed offence → compounded before or after prosecution → on payment of the prescribed sum to the Government

Section 40 is not among the offences listed for compounding.

Compounding limit (section 48(3) proviso)

Compounding sum ≤ maximum fine for that offence

The proviso sits in sub-section (3), so be careful when applying it.

Repeat offence bar (section 48(4))

Same or similar offence within 3 years of compounding → no compounding

An offence after 3 years from the earlier compounding is treated as a first offence.

Effect of compounding (section 48(5))

Offence compounded → no further proceedings for that offence

This gives the offender finality.

Company offences (section 49)

Company + nominated person (or, if none, every person in charge and responsible) = deemed guilty

Defence: offence without knowledge and all due diligence exercised. Others liable on consent, connivance or neglect.

Quick revision

• Section 7 makes the base units in section 5 the standard units of weights and measures, and the base unit of numeration in section 6 the standard unit of numeration.
• Section 18(1) bars manufacturing, packing, selling, importing, distributing, delivering, offering, exposing or possessing for sale any pre-packaged commodity that lacks the prescribed standard quantities and declarations.
• Section 18(2): an advertisement mentioning the retail sale price of a pre-packaged commodity must declare the net quantity or number.
• Section 13: the Central Government appoints the Director and officers for inter-State trade and commerce.
• Section 14: the State Government appoints the Controller and officers for intra-State trade and commerce.
• Officers under section 13 work under the Director's superintendence, direction and control; officers under section 14 work under the Controller's.
• Officers are deemed public servants, and no legal proceeding lies for anything done in good faith under the Act.
• Section 40: obstructing the Director, Controller or an officer is punishable with imprisonment up to two years, and up to five years for a second or later offence.
• Section 48: offences may be compounded before or after prosecution, on payment of the prescribed sum.
• Section 48(4): compounding does not apply to the same or similar offence within three years of the earlier compounding.

• Section 52: the Central Government makes rules, which must be laid before Parliament for thirty days.

Common mistakes

• Saying a pre-packaged commodity must be sealed. Fix: Remember the words: in a package of whatever nature, whether sealed or not. The key tests are absence of the purchaser and a pre-determined quantity.
• Listing the Director and Controller inside the definition of legal metrology officer. Fix: Section 2(h) lists Additional, Joint, Deputy and Assistant Directors and Controllers, and Inspectors. The Director and Controller are defined separately in s 2(c) and 2(a).
• Listing fewer than seven base units or mixing in derived units like litre or newton. Fix: Memorise the seven pairs: metre, kilogram, second, ampere, kelvin, candela, mole.
• Saying a reference standard is valid once it is made to specification. Fix: State that section 9(2) requires verification and stamping, and 9(3) says otherwise it is not a valid standard.
• Saying verification is needed merely because someone possesses a weight or measure. Fix: Always add the condition: circumstances indicating use or likely use in a transaction or for protection.
• Saying verification can be done after use begins. Fix: State that verification must be done before putting the weight or measure into such use.
• Saying the package must be sealed to be pre-packaged. Fix: Section 2(l) says "whether sealed or not". The test is the buyer's absence and the pre-determined quantity.
• Applying section 18 to goods weighed in front of the customer. Fix: Check the definition first. If the buyer is present at packing, it is not a pre-packaged commodity.
• Saying the Central Government appoints the Controller. Fix: Remember: Director goes with Centre (section 13), Controller goes with State (section 14).
• Treating section 14 as covering inter-State trade. Fix: Always attach the scope: section 14 officers act in relation to intra-State trade and commerce only.

Exam tips

• Learn section 2 definitions in groups: people, things, activities. This helps you recall them quickly in short notes.
• Quote the key words of definitions such as pre-packaged commodity and legal metrology officer. Paraphrasing loses marks when elements are missed.
• In fact-based questions, apply each element of the definition separately before concluding.
• Cite section numbers only when you are sure. Section 1, 2, 11 and 18 are safe to cite from this topic.
• Link definitions to later provisions: pre-packaged commodity leads to section 18, and obstruction of officers is dealt with in section 40.
• Write section numbers beside each rule. ICSI answers reward the provision first, then analysis, then conclusion.
• Learn the seven base units as a table in your head so you can write them in under a minute.
• Remember that detail like fees, tolerances and procedures is left to rules under section 52. Say so instead of guessing figures.
