What is the significance of the Explanation provided in section 288?
The Explanation provided in section 288 clarifies that the term "law of a State in force" includes laws passed or made before the commencement of the Constitution, which were not previously repealed, even if they were not operational either at all or in specific areas. This ensures that older laws related to taxing water or electricity are still considered valid and enforceable unless explicitly overridden by the President through an order.
