 F.A. Hayek was by training an economist, but he also nurtured an interest in the relation between legal structures and forms of national economy. Hayek’s work on the Rule of Law proceeded in two phases: (1) from his wartime book The Road to Serfdom (1944) through to The Constitution of Liberty (Hayek 1960); and (2) the somewhat different account presented in his trilogy, Law, Legislation and Liberty (1973), an account which is more congenial to the spirit of common law and hostile to the role of legislation.
