If society wishes to maintain an independent judiciary, it faces the problem of how to restrain judges from indulging their personal whims. One restraint is the desire of judges to influence future judges. To do so, they may have to maintain their own or the system's legitimacy by restraining their own behavior. This situation is usefully viewed as an equilibrium of an infinitely repeated game.
