We have thus an organ for the interpretation of natural law free from the shifting variety of individual judgment. We have a means for securing impartial justice between members of civil society, and to that means the force of men has been surrendered. The formulation of the rules by which life, liberty and property are to be secured is legislation and this, from the terms of the original contract, is the supreme function of the State. But, in Locke's view, two other functions still remain. Law has not only to be declared. It must be enforced; and the business of the executive is to secure obedience to the command of law. But Locke here makes a third distinction. The State must live with other States, both as regards its individual members, and as a collective body; and the power which deals with this aspect of its relationships, Locke termed "federative." This last distinction, indeed, has no special value; and its author's own defence of it is far from clear. More important, especially, for future history, was his emphasis of the distinction between legislature and executive. The making of laws is for Locke a relatively simple and rapid task; the legislature may do its work and be gone. But those who attend to their execution must be ceaseless in their vigilance. It is better, therefore, to separate the two both as to powers and persons. Otherwise legislators "may exempt themselves from obedience to the laws they make, and suit the law, both in its making and its execution, to their own private wish, and thereby come to have a distinct interest from the rest of the community, contrary to the end of society and government." The legislator must therefore be bound by his own laws; and he must be chosen in such fashion that the representative assembly may fairly represent its constituencies. It was the patent anomalies of the existent scheme of distribution which made Locke here proffer his famous suggestion that the rotten boroughs should be abolished by executive act. One hundred and forty years were still to pass before this wise suggestion was translated into statute.
