The duties of the Union or Central Government include subjects of national importance such as defence of the country, foreign affairs, banking, communications and currency. This is because, a uniform policy on these matters will be maintained throughout the country. All the laws pertaining to the above duties must be given only by the Union Government. The duties of the State Governments include subjects of the State and local importance such as police, trade, commerce, agriculture and irrigation. All the laws pertaining to the above duties must be given only by the State Governments. Some aspects have to be taken care of, by both, the Union Government as well as the State Governments. They are education, forest, trade unions, marriage, adoption and succession. Both governments can make laws on these subjects. If their laws conflict with each other, the law made by the Union Government will prevail.
