The features or principles of parliamentary government in India are:
Nominal and Real Executives
The President is the nominal executive (de jure executive or titular executive) while the Prime Minister is the real executive (de facto executive). Thus, the President is head of the State, while the Prime Minister is head of the government. Article 74 provides for a council of ministers headed by the Prime Minister to aid and advise the President in the exercise of his functions. The advice so tendered is binding on the President.
Majority Party Rule
The political party which secures majority seats in the Lok Sabha forms the government. The leader of that party is appointed as the Prime Minister by the President; other ministers are appointed by the President on the advice of the prime minister. However, when no single party gets the majority, a coalition of parties may be invited by the President to form the government.
Collective Responsibility
This is the bedrock principle of parliamentary government. The ministers are collectively responsible to the Parliament in general and to the Lok Sabha in particular (Article 75). They act as a team, and swim and sink together. The principle of collective responsibility implies that the Lok Sabha can remove the ministry (i.e., council of ministers headed by the prime minister) from office by passing a vote of no confidence.
Political Homogeneity
Usually members of the council of ministers belong to the same political party, and hence they share the same political ideology. In case of coalition government, the minister are bound by consensus.
Double Membership
The ministers are members of both the legislature and the executive. This means that a person cannot be a minister without being a member of the Parliament. The Constitution stipulates that a minister who is not a member of the Parliament for a period of six consecutive months ceases to be a minister.
