State Enforcement Rules

The Legal Metrology Enforcement Rules is the tool by which the State Authorities enforce various provisions of the Legal Metrology Act, 2009 and Rules made thereunder. Section 53 of the Act provides that State Government may make rules, after consultation with the Central government, for carrying out various provisions of the Act.

Different State Governments have notified their Enforcement Rules to be effective from different dates and also there are some deviations from the Model Rule circulated by the Central government.

The Rules of a particular state should be consulted for the exact provision and the Schedule applicable in that state.

However, some states like Maharashtra allows you to do so while in other states, you may be penalized. Consult your State Rules.

Suspension and cancellation of license

A license may be suspended and finally may be cancelled, if an enquiry shows that the licensee was obtained by furnishing false information or the licensee has violated any provisions of the Act or Rules or terms or conditions of license.

During the suspension period, the licensee cannot continue his business but, if the enquiry is not completed within three months, the suspension order lapses automatically.
