The Indian Constitution defines the role of governors in the states as per Article 153 and Articles 155 to 161. The role of governors in India's federal structure can be explained as follows: 1. Constitutional Head: Governors are the ceremonial heads of states and represent the President at the state level. 2. Executive Powers: Governors exercise executive powers on various matters including the appointment of the Chief Minister, the Council of Ministers, and the Advocate General of the state. 3. Legislative Functions: Governors summon and prorogue the sessions of the state legislature and can address and send messages to the House. They also give their assent to bills passed by the Legislature. 4. Emergency Powers: In the event of a breakdown of constitutional machinery in a state, the governor can take over the administration and exercise emergency powers. 5. Discretionary Powers: Governors exercise their discretion while performing various functions, like seeking information from the Chief Minister, observing directions of the President, and seeking advice from the Council of Ministers. While governors have broad powers bestowed upon them by the Constitution, it is important to note that they are expected to perform their duties in accordance with the advice of the Council of Ministers headed by the Chief Minister, thus maintaining the federal structure of India.
