Why statutory authorities need independence
Launch library · evergreen read

A statutory authority is created by legislation to perform a specific public function, often one that benefits from sitting at arm's length from day to day political direction, such as regulating a licensed profession or managing a competitive market. That distance is deliberate, since ministers change but the underlying function needs to keep running consistently.
Independence is usually protected through the way the authority's leadership is appointed and removed, the security of its funding, and clear legislative limits on when a minister can actually direct its decisions. Weakening any one of these three protections tends to weaken the others in practice, since independence rarely fails all at once.
The tradeoff is accountability, since an independent authority still needs to answer for its decisions somewhere, typically through public reporting, parliamentary scrutiny or judicial review of its actions. Independence from day to day politics is not meant to mean independence from accountability altogether, and the strongest authorities manage to hold both at once.
