Article 3 of the Indian Constitution deals with the formation of new states and alteration of areas, boundaries or names of existing states.

Process of forming a new state:
1. Proposal: The first step in the formation of a new state is the proposal made by the Parliament. The Parliament can either initiate the proposal on its own or based on a recommendation by the concerned state legislature.

2. Consultation: Once the proposal is made, the President of India is required to refer it to the concerned state legislature for expressing its views within a specified time period. The President may also refer the proposal to the Governor of the concerned state for his/her opinion.

3. Bill in Parliament: After taking into consideration the views of the concerned state legislature and the Governor, the Parliament may pass a bill to form the new state or alter the boundaries of existing states. The bill must be passed by a simple majority of the total membership of each house of Parliament and a two-thirds majority of the members present and voting.

4. Assent of President: After the bill is passed by Parliament, it is presented to the President for his/her assent. If the President gives his/her assent, the bill becomes an Act and the new state is formed or the boundaries of existing states are altered.

Conclusion:
Thus, Article 3 provides a detailed process for the formation of a new state or alteration of the boundaries of existing states in India. The process ensures that the views of the concerned state legislature and the Governor are taken into consideration before any decision is made.
