During the times of emergency in the Indian Union the President is vested with special powers and he also becomes the real head of the country.

The President of India has the power to declare three types of emergency. They are National Emergency, State Emergency and Financial Emergency.

According to Article 352 If the President believes that there is a threat to the security of India or to the security of a part of India, he has the power to declare National Emergency. But the President cannot declare National Emergency without the written advice of the Union Cabinet to avoid mis use of power.

Under Article 356 the President can declare 'State Emergency' or President's Rule either on the basis of a report of the Governor or otherwise that the constitutional machinery of that state has failed. During state Emergency, the President of India assumes all executive power of the state to himself. The state administration is run directly by him or through a person designated for the purpose by him. It is the Governor of state who runs the state administration on behalf of the President.

Under Article 360, the President of India can proclaim Financial Emergency if he is satisfied that the financial stability or the credit of India or of any part of its territory is threatened.

The National Emergency and Financial Emergency have no time limit. They can continue to be extended without any limit. But the State Emergency has a time-limit. It cannot go beyond three years.

It is correct that politics is more than what politicians do. Politicians as a part of government are involved in politics but politics is not limited to their activities. Politics involves number of various negotiations that go on in society through which collective decisions are made.

1. Politics involves the actions of government and its relation to the aspirations of the people.
2. Politics involves the struggle of people and its influence on decision making. 
3. People are engaged in political activity whenever they negotiate with each other and participate in collective activities that are designed to promote social development and resolve common problems.
4. For example, residents of localities form associations to solve their common problems and raise these issues at higher level.
5. Students form unions in colleges and universities to debate and resolve issues that affect the majority of them.
6. Thus, politics is involved in the sphere of life that is related to power, collective decision-making and solving common problems.

The three principles of justice outlined in the chapter are discussed below:
(i)First, one of the principle in the principle of treating equals equally. It is considered that all individuals share certain characteristics as human beings. Therefore they deserve equal rights and equal treatment. Some of the important rights which are granted to most liberal democracies today include civil rights such as the rights of life, liberty and property, political rights like the right to vote, which enable people to participate in political processes and certain social rights which would include the right to enjoy equal opportunities with other members of the society.
(ii)Second, apart from the equal rights, the principle of treating equals equally would require that people should not be discriminated against on grounds of class, caste, race or gender. They should be judged on the basis of their work and actions and not on the basis of group to which they belong.

Therefore, if two persons from different castes participate in the same type of work, whether it be breaking stores or delivering pizzas they should receive the same type of reward.
