Powers of State Governments curtailed

Earlier State Governments were allowed to approve models of weights and measures intended to be used exclusively within the State under Section 73 of the SoWM (Enforcement) Act, 1985. The provision has not been included in the Legal Metrology Act, 2009.

The State Government has now no authority to grant approval of a model. The State laboratories are not competent to test any model, unless the laboratory is recognized for such tests by the GOI or the task has been assigned to it.

This will be a major problem for small manufacturers who sell their products within the state.
