Step 1: Establishment: The Central Vigilance Commission (CVC) was established in 1964 by an executive resolution to combat corruption in the central government.
Step 2: Statutory Status: In 2003, the CVC was given statutory status through the Central Vigilance Commission Act, granting it legal powers, but it remains a statutory body, not a constitutional one.
Step 3: Difference Between Bodies: A constitutional body is created by the Constitution itself (e.g., Election Commission), whereas a statutory body is created by a law passed by Parliament. The CVC falls in the latter category.
Step 4: Functions: The CVC oversees vigilance administration and investigates corruption allegations within central government offices.
Thus, the incorrect statement is that the CVC is a constitutional body; it is actually a statutory body.
