Supervisory Power Law and Legal Definition

Supervisory power refers to the power of oversight over an inferior body. It does not include any restraining authority over the supervised party.

The following is an example of a case law on supervisory power:

Under their supervisory power, courts have substantial authority to oversee their own affairs to ensure that justice is done. They do not, however, have a license to intrude into the authority, powers and functions of the coordinate branches. [United States v. Simpson, 927 F.2d 1088 (9th Cir. 1991)].
