How does the central government's regulation over weights and measures affect state-level competencies?
The central government's regulation over weights and measures affects state-level competencies by providing an overarching framework for standardizing measurements across the country. This ensures that there is a consistent and uniform system of measurements, which can be beneficial for trade, commerce, and the overall functioning of various industries. However, states still have some level of autonomy in implementing and enforcing these standards within their jurisdiction as per the provisions of entry 50 of List I of the Seventh Schedule.
