Explanation:

After a bill is passed in both Houses of Parliament, it is then sent to the President for his or her assent. This step is known as the President's assent or the President's approval. The President is the head of state in India and holds the highest office in the country. The President's role in the lawmaking process is crucial, as he or she acts as the final authority before a bill becomes law.

Process of Passing a Bill:
1. Introduction: The bill is first introduced in either the Lok Sabha (Lower House) or the Rajya Sabha (Upper House) by a minister or a member of Parliament.

2. Discussion and Voting: The bill goes through various stages of debate, discussion, and amendments in both Houses of Parliament. Members of Parliament have the opportunity to present their views, ask questions, propose changes, and vote on the bill.

3. Passage in Both Houses: If a bill is passed in one House, it is then sent to the other House for consideration. Both Houses need to agree on the exact wording and provisions of the bill for it to be passed.

4. President's Assent: Once the bill is passed in both Houses of Parliament, it is sent to the President for his or her assent. The President reviews the bill and can either give his or her assent, withhold his or her assent, or return the bill for reconsideration.

Role of the President:
The President's role in the lawmaking process is primarily ceremonial, but it is an important constitutional duty. The President represents the unity and integrity of the nation and ensures that the laws passed by Parliament are in accordance with the Constitution. The President's assent is required for a bill to become law.

Conclusion:
In conclusion, after a bill is passed in both Houses of Parliament, it is sent to the President for his or her assent. The President plays a crucial role in the lawmaking process and acts as the final authority before a bill becomes law.
