Why should there be a president in India if he cant take decisions on his own ?

Question

As you see, in India, the president cant take his own decisions though he is called the supreme commander of the army or appointer of chief justice etc, He can only take those decisions by the advice of the council of ministers, the only decision he can take on his own is appointing the Prime Minister, and thats pretty vague, the PM can also be elected by the people.

Answer 1

Because USA is the exception, not the rule.
Most countries presidents have very strong powers, but rarely use them, USA has a more "royal" sovereign leader, that not only has ultimate power, but uses it.
Think of the difference between USA and India, two republics with Presidents, as the difference between Saudi Arabia and UK, two monarchs. (I'm not trying to say the USA is the same as Saudi Arabia just trying to show the difference)
In the USA President and Saudi Arabian King both have absolute power (granted the Saudi Arabian King has more), however the Indian President and UK queen are more there to make sure it goes smoothly, not really to interfere with parliment, unless of course is required.
It would be rare for the Queen to refuse to sign a bill into law, but in USA, not so uncommon.

Answer 2

The President of India selects:

* Governors of States
* The Chief Justice and other judges of the Supreme Court and High Courts
* The Attorney General
* The Comptroller and Auditor General
* The Chief Election Commissioner and other Election Commissioners
* The Chairman and other Members of the Union Public Service Commission
* Ambassadors and High Commissioners to other countries.

The President also receives the credentials of Ambassadors and High Commissioners from other countries.

The President is the Commander in Chief of the Indian Armed Forces.

The President of India can grant a pardon to or reduce the sentence of a convicted person, particularly in cases involving punishment of death.
The decisions involving pardoning and other rights by the president are independent of the opinion of the Prime Minister or the Lok Sabha majority.

The President can declare three types of emergencies:

* National emergency
* State emergency
* Financial emergency

The President summons both houses of the Parliament and prorogues them. He can even dissolve the Lok Sabha. These powers are formal, and by convention, the President uses these powers according to the advice of the Council of Ministers headed by the Prime Minister.

They inaugurate the Parliament by addressing it after the general elections and also at the beginning of the first session each year. Their address on these occasions is generally meant to outline the new policies of the government. This address is essentially identical in nature to a Speech from the Throne.

A bill that the Parliament has passed, can become a law only after the President gives their assent to it. They can return a bill to the Parliament, if it is not a money bill, for reconsideration. However, if the Parliament sends it back to them for the second time, they are obliged to assent to it.

When the Parliament is not in session and the government considers it necessary to have a law, then the President can promulgate ordinances. These ordinances are submitted to the Parliament at its next session. They remain valid for no more than six weeks from the date the Parliament is convened unless approved by it earlier.

Answer 3

The President must decide on his own volition even when he has advisers.
