Hayek on the Rule of Law
Hayek defines the rule of law as the requirement that government action be bound by rules fixed and announced beforehand, so that individuals can foresee how coercive powers will be used and plan their own affairs accordingly. Comprehensive economic planning, on Hayek’s account, requires the opposite — discretionary administration that cannot tie itself to general rules in advance. The two principles of social organization are therefore not points on a spectrum but mutually exclusive.
The Passage
“Nothing distinguishes more clearly a free country from a country under arbitrary government than the observance in the former of the great principles known as the Rule of Law. Stripped of technicalities this means that government in all its actions is bound by rules fixed and announced beforehand — rules that make it possible to foresee with fair certainty how the authority will use its coercive powers in given circumstances and to plan one’s individual affairs on the basis of this knowledge. … Socialist economic planning necessarily involves the very opposite of this. The planning authority cannot tie itself down in advance to general rules which prevent arbitrariness.”
What the Argument Requires
The passage is doing two things at once. The first is a definition: the rule of law is the foreseeability condition, not a generic appeal to “legality.” A regime in which the legislature passes a statute empowering an agency to do whatever it pleases satisfies a thin formal-legality standard but does not satisfy Hayek’s rule-of-law condition, because the citizen cannot foresee how the coercive power will be used. The second is a structural claim: planning of a substantive economic outcome cannot be reduced to general rules, because the planner must decide “how many pigs are to be raised or how many buses are to run, which coal-mines are to operate, or at what prices shoes are to be sold.” Such decisions depend on circumstances of the moment and cannot be settled for long periods in advance. Discretion is therefore not an accident of bad implementation; it is intrinsic to substantive planning.
The corollary is the one The Road to Serfdom is named for: once law becomes the legalization of substantive administrative discretion, the citizen’s capacity to plan is replaced by dependence on the discretion of administrators, and the institutional habits of liberty erode. The argument is therefore institutional rather than merely procedural. The rule of law is the precondition under which private planning is possible; substantive planning destroys that precondition by construction, not by abuse.
Relation to the Current Wiki
Hayek’s foreseeability condition sits at the level of State Power and Intervention and supplies the classical-liberal limit on permissible state action that Mises shares in Liberalism. It is the constraint a programmable monetary medium would invert: when the central bank can attach expiry, geographic limits, category refusals, or identity gating to balances at its own discretion, citizens can no longer “plan one’s individual affairs on the basis of this knowledge.” That makes the rule-of-law concept the natural Hayekian bridge from the knowledge problem to applied analysis of contemporary monetary architecture.
