Explanation:

UPSC is only a central recruiting agency while the Department of Personnel and Training is the central personnel agency in India.The role of UPSC is not only limited, but also recommendations made by it are only of advisory nature and hence, not binding on the government. It is upto the Union government to accept or reject that advise. The only safeguard is the answerability of the government to the Parliament for departing from the recommendation of the Commission. Further, the government can also make rules which regulate the scope of the advisory functions of UPSC.
The emergence of Central Vigilance Commission (CVC) in 1964 affected the role of UPSC in disciplinary matters. This is because both are consulted by the government while taking disciplinary action against a civil servant. The problem arises when the two bodies tender conflicting advise. However, the UPSC, being an independent constitutional body, has an edge over the CVC, which is created by an executive resolution of the Government of India and conferred a statutory status in October 2003.
