During President's Rule, IAS officers do not have the authority to exercise the powers of a minister. However, they may assume additional responsibilities and decision-making power due to the absence of an elected government. Here are the key points to note:

• Under Article 356 of the Constitution of India, President's Rule can be imposed in a state due to various reasons such as a breakdown of governance, constitutional crisis, or failure of the constitutional machinery.
• During this period, the Governor assumes the role of the head of the state, with the support of the Central Government.
• IAS officers, as administrators and civil servants, play a crucial role in managing the state's affairs and implementing government policies effectively.
• While they may have more decision-making powers and authority during President's Rule, their role is limited to administrative functions and not political decision-making.
• Their primary responsibilities include maintaining law and order, managing public services, and ensuring the smooth flow of governance until a new government is formed.

Overall, while IAS officers may assume more responsibilities during President's Rule, they do not have the authority to exercise the powers of a minister.
