The ref has to be more powerful than the players.
When neoliberal economists began dismantling the regulatory state under Ronald Reagan (a process that has continued without interruption under every president, Republican and Democrat, since), they insisted that they weren’t so much concerned with regulation, but rather, regulatory capture.
Today, the phrase “regulatory capture” gets thrown around by people of all political persuasions, and is understood in a colloquial sense, meaning something like, “a regulator who is beholden to its industry and therefor makes bad regulations that run counter to the public interest.”
