Which features of Indian constitution was borrowed from USA?

The Indian Constitution has borrowed several features from the Constitution of the United States of America. Here are some of them:

2. Federal Structure of Government: Although the word is not used in the Constitution itself, the Indian government is a federal one in nature, with powers clearly divided between the central and state governments. This concept was borrowed from the US Constitution.

3. Supreme Court: The establishment of the Supreme Court and its role as the guardian of the Constitution is another feature borrowed from the US.

4. Fundamental Rights: The concept of fundamental rights, which are essential for the development of every individual and which are protected by the judiciary, is taken from the US Constitution.

6. Preamble: The concept of a preamble, which outlines the objectives of the Constitution, is borrowed from the US.

7. Impeachment of the President: The procedure to impeach the President for violation of the Constitution is taken from the US Constitution.
