The Federal Communications Commission has ancillary authority under section 4(i) of the Communications Act of 1934, which authorizes the Commission to "perform any and all acts, make such rules and regulations, and issue such orders, not inconsistent with this chapter, as may be necessary in the execution of its functions." The Commission may exercise this “ancillary” authority only if it demonstrates that its action is “reasonably ancillary to the . . . effective performance of its statutorily mandated responsibilities.”
