How did the President's power over major ports and aerodromes change after this amendment?
After the Constitution (Twenty-sixth Amendment) Act, 1971, the President could issue public notifications directing that certain laws or existing laws would either not apply to major ports or aerodromes or would have exceptions or modifications in their application. This power allowed the President to make specific adjustments to the legal framework governing these areas for the benefit of national interests or specific needs at the time.
