What are some possible implications of the provisions in Article 297 for India's maritime zones?
Some possible implications of the provisions in Article 297 for India's maritime zones are:

1. The Union government has complete control over all lands, minerals, and other valuable resources found within India's territorial waters, continental shelf, and exclusive economic zone (EEZ). This means that states cannot make decisions or laws regarding these resources without approval from the Union government.
2. The Union government can exploit and utilize these resources for the benefit of the nation, subject to any laws enacted by the Parliament.
3. The limits of India's maritime zones (territorial waters, continental shelf, EEZ) can be adjusted or modified by the Parliament through legislation as per national interests.
4. State governments may have some role in managing trade and business related to the resources within their territorial waters, but they must abide by any federal laws enacted by the Union government.
5. The EEZ's resources, such as fish stocks and oil reserves, are also vested in the Union government for purposes of governance and economic development.
