Impeachment of the President is a quasi-judicial procedure in Parliament because it is a process that involves elements of both legislative and judicial functions. This process is outlined in Article 61 of the Constitution of India.

The following are the reasons why the impeachment of the President is a quasi-judicial procedure in Parliament:

1. The Procedure Resembles Judicial Proceedings: The impeachment process is similar to a judicial proceeding in that it requires a trial, witnesses, and evidence. The President is given an opportunity to defend himself, and the proceedings are conducted in a manner similar to that of a court of law.

2. The Charges Against the President Are Similar to an Indictment: Before the impeachment process begins, the charges against the President are presented to the Lok Sabha. These charges are similar to an indictment in a criminal trial.

3. The Role of the Rajya Sabha: The Rajya Sabha acts as a quasi-judicial body during the impeachment process. The Rajya Sabha Chairman presides over the trial, and the members of the Rajya Sabha act as judges.

4. The Vote: The vote on the impeachment of the President is similar to a verdict in a criminal trial. A two-thirds majority is required in both the Lok Sabha and the Rajya Sabha for the President to be impeached.

In conclusion, the impeachment of the President is a quasi-judicial procedure in Parliament because it involves elements of both legislative and judicial functions. The process is similar to a court trial, and the Rajya Sabha acts as a quasi-judicial body during the proceedings.
