The excerpt reflects the unitary feature of the Indian Constitution.

Although India has a federal structure, certain provisions in the Constitution give greater authority to the Union Government. One such unitary feature is that the Governor of a State can reserve a Bill passed by the State Legislature for the consideration of the President of India.

The President may give or withhold assent to such Bills, thereby exercising control over State legislation. This indicates that the States are not fully sovereign in their law-making powers, and the ultimate authority lies with the Centre, which is a unitary characteristic of the Constitution.
