The Constitution considers UPSC to be the ‘watch-dog of merit system’ in India. It is concerned with the recruitment to the all-India and central services - group A and group B.
It advises the government, when consulted, on promotion and disciplinary matters.
It is not concerned with the classification of services, pay and service conditions, cadre management, training etc., which are handled by the Department of Personnel and Training of the Ministry of Personnel, Public Grievances and Pensions. Hence statement 1 is incorrect.
Recommendations made by it are only of advisory nature and not binding on the government. The only safeguard is the answerability of the government to the Parliament for deviating from the recommendation of the commission.
The Chairman or a member of the UPSC can be removed from office by the President only in the manner and on the grounds mentioned in the Constitution.
The conditions of service of the Chairman or a member, though determined by the President, cannot be varied to his disadvantage after his appointment.
The Chairman of UPSC on ceasing to hold office is not eligible for further employment in the Government of India or a state.
A member of UPSC on ceasing to hold office is eligible for appointment as the Chairman of UPSC or a State Public Service Commission (SPSC), but not for any other employment in the Government of India or a state. Hence statement 2 is correct.
The Chairman or a member of UPSC after having completed his first term is not eligible for re-appointment to that office. Thus, there is no second term for the same office.
Hence statement 3 is incorrect.
