We see the same design in the context of other “guardian institutions” like the Election Commission of India, the Comptroller & Auditor General (CAG) of India and the Union Public Service Commission (UPSC). When it comes to removal, the first two are on a par with Supreme Court judges. UPSC members can be removed by the President on grounds of misbehaviour only after the Supreme Court (SC) has conducted an inquiry and reported that the member ought to be removed.
The Constitution does not explicitly refer to what is called the “fourth branch” of government in other parts of the world and statutory regulatory authorities (SRAs) in India. However, the principles noted above apply equally to SRAs. SRAs are created by Parliament to perform specific functions that require expertise, continuity, and political neutrality. As markets developed and the need for consumer protection became stronger, arm’s length agencies were created by enlightened Indian parliamentarians. By design, SRAs like the Reserve Bank of India (RBI), the Securities and Exchange Board of India (Sebi), and the Telecom Regulatory Authority of India (Trai), are not appendages of the government of the day. In fact, very often, they regulate entities owned by government.
