The base of democracy is the idea of consent, i.e. the desire, approval and participation of people. The basic idea is that the individual or the citizen is the most important person and that in principle the government as well as other public institutions needs to have the trust of the citizens.
Election is the way by which the individual give approval to the government. People elect their representatives to the Parliament, then, one group from among these elected representatives forms the government. The Parliament controls and guides the government. In this sense people, through their chosen representatives, form the government and also control it.
Created after 1947, the Indian Parliament is an expression of the faith that the people of India have in principles of democracy i.e. participation by people in the decision-making process and government by consent. The Parliament in our system has immense powers because it is the representative of the people. Elections are held in a similar manner as they are for the state legislature. The Lok Sabha is usually elected once every five years. The country is divided into numerous constituencies.
Each of these constituencies elects one person to the Parliament. The candidates who contest elections usually belong to different political parties.
Once elections to the parliament have taken place the parliament mainly needs to perform three functions.
For a political party to form the government, they must have a majority of elected MPs. Since there are 543 elected (Plus 2 nominated) members in Lok Sabha, to have a majority, a party should have at least half the number i.e. 272 members or more.
Framing of laws and amendments to previous laws is an important function of the legislature. The proposal for a law is called a bill. It is of two kinds - ordinary bill and money bill. Until a bill is passed through a proper procedure, it cannot be a law or an act.
