Law is the body of legal norms. A legal norm is a norm which is based on the fact that men have the will to see a certain procedure generally observed within a circle which includes themselves.

1. A legal norm is a norm.

A norm is the idea of a correct procedure. A correct procedure means one that corresponds either to the final purpose of all human procedure (unconditionally correct procedure,—for instance, respect for another's life), or at any rate to some accidental purpose (conditionally correct procedure,—for instance, the skilled handling of a picklock). And the idea of a correct procedure means that the unconditionally or conditionally correct procedure is to be thought of not as a fact but as a task, not as something real but as something to be realized; it does not mean that I shall in fact spare my enemy's life, but that I am to spare it—not how the thief really did use the picklock, but how he should have used it. The idea of a correct procedure is what we designate as an "ought": when I think of an "ought," I think of what has to be done in order to realize either the final purpose of all human procedure or some accidental personal purpose. All passing of judgment on past procedure is conditioned upon the idea of a correct procedure—only with regard to this idea can past procedure be described as good or bad, expedient or inexpedient; and so is all deliberation on future procedure—only with regard to this idea does one inquire whether it will be right, or at any rate expedient, to proceed in a given manner.

Every legal norm represents a procedure as correct, declares that it corresponds to a particular purpose. And it represents this correct procedure as an idea, designates it not as a fact but as a task, does not say that any one does proceed so but that one is to proceed so. Hence a legal norm is a norm.

2. A legal norm is a norm based on a human will.

A norm based on a human will is a norm by virtue of which one must proceed in a certain way in order that he may not put himself in opposition to the will of some particular men, and so be apprehended by the power which is at the service of these men. Such a norm, therefore, represents a procedure only as conditionally correct; to wit, as a means to the end (which we are perhaps pursuing or perhaps despising) of remaining in harmony with the will of certain men, and so being spared by the power which serves this will.

Every legal norm tells us that we must proceed in a certain way in order that we may not contravene the will of some particular men and then suffer under their power. Therefore it represents a procedure only as conditionally correct, and instructs us not as to what is good but only as to what is prescribed. Hence a legal norm is a norm based on a human will.

3. A legal norm is a norm based on the fact that men will to have a certain procedure for themselves and others.

A norm is based on the fact that men will to have a certain procedure for themselves and others when the will on which the norm is based has reference not only to others who do not will, but also, at the same time, to the willers themselves also; when, therefore, these not only will that others be subject to the norm but also will to be subject to it themselves.

Every legal norm, and of all norms only the legal norm, has the characteristic that the will on which it is based reaches beyond those whose will it is, and yet embraces them too. The rule, "Whoever takes from another a movable thing that is not his own, with the intent to appropriate it illegally, is punished with imprisonment for theft," is not only based on the will of men, but each of these men is also conscious that, while on the one hand the rule applies to other men, on the other hand it applies to himself.

Here it might be alleged that, after all, the mere fact of men's will to have a certain procedure for themselves and others does not always establish law; for example, the efforts of the Bonapartists do not establish the empire in France. But it is not when this bare will exists that law is established, but only when a norm is based on this will; that is, when it has in its service so great a power that it is competent to affect the behavior of the men to whom it relates. As soon as Bonapartism spreads so widely and in such circles that this takes place, the republic will fall and the empire will indeed become law in France.

One might further appeal to the fact that in unlimited monarchies (in Russia, for instance) the law is based solely on the will of one man, who is not himself subject to it. But Russian law is not based on the czar's will at all; the czar is a weak individual man, and his will in itself is totally unqualified to affect many millions of Russians in their procedure. Russian law is based rather on the will of all those Russians—peasants, soldiers, officials—who, for the most various reasons—patriotism, self-interest, superstition—will that what the czar wills shall be law in Russia. Their will is qualified to affect the procedure of the Russians; and, if they should ever grow so few that it would no longer have this qualification, then the czar's will would no longer be law in Russia, as the history of revolutions proves.

4. It has been asserted that legal norms have still other qualities.

It has been said, first, that it belongs to the essence of a legal norm to be enforceable, or even to be enforceable in a particular way, by judicial procedure, governmental force.

If by this we are to understand that conformity can always be enforced, we are met at once by the great number of cases in which this cannot be done. When a debtor is insolvent, or a murder has been committed, conformity to the violated legal norms cannot now be enforced after the fact, but their validity is not impaired by this.

If by enforceability we mean that conformity to a legal norm must be insured by other legal norms providing for the case of its violation, we need only go on from the insured to the insuring norms for a while, to come to norms for which conformity is not insured by any further legal norms. If one refuses to recognize these norms as legal norms, then neither can the norms which are insured by them rank as legal norms, and so, going back along the series, one has at last no legal norms left.

Only if one would understand by the enforceability of the legal norm that a will must have at its disposal a certain power in order that a legal norm may be based on it, one might certainly say in this sense that enforceability belongs to the essence of a legal norm. But this quality of the legal norm would be only such a quality as would be derivable from its quality of being a norm, and would therefore have no claim to be added as a further quality.

Again, it has been named an essential quality of a legal norm that it should be based on the will of a State. But even where we cannot speak of a State at all, among nomads for instance, there are yet legal norms. Besides, every State is itself a legal relation, established by legal norms, which consequently cannot be based on its will. And lastly, the norms of international law, which are intended to bind the will of States, cannot be based on the will of a State.

Finally, it has been asserted that it was essential to a legal norm that it should correspond to the moral law. If this were so, then among the different legal norms which to-day are in force one directly after the other in the same territory, or at the same time in different territories under the same circumstances, only one could in each case be regarded as a legal norm; for under the same circumstances there is only one moral right. Nor could one speak then of unrighteous legal norms, for if they were unrighteous they would not be legal norms. But in reality, even when legal norms determine conduct quite differently under the same circumstances, they are all nevertheless recognized as legal norms; nor is it doubted that there are bad legal norms as well as good.

5. As a norm based on the fact that men have the will to see a certain procedure generally observed within a circle which includes themselves, the legal norm is distinguished from all other objects, even from those that most resemble it.

By being based on the will of men it is distinguished from the moral law (the commandment of morality); this is not based on men's willing a certain procedure, but on the fact that this procedure corresponds to the final purpose of all human procedure. The maxim, "Love your enemies, bless those who curse you, do good to those who hate you, pray for those who abuse and persecute you," is a moral law; so is the maxim, "Act so that the maxims of your will might at all times serve as the principles of a general legislation." For the correctness of such a procedure is not founded on the fact that other men will have it, but on the fact that it corresponds to the final purpose of all human procedure.

By being based on the will of men the legal norm is distinguished also from good manners; these are not based on the fact that men will a certain procedure, but on the fact that they themselves proceed in a certain way. It is manners that one goes to a ball in a dress coat and white gloves, uses his knife at table only for cutting, begs the daughter of the house for a dance or at least one round, takes leave of the master and mistress of the house, and lastly presses a tip into the servant's hand; for the correctness of such a behavior is not based on the fact that other men ask this of us,—to those who start a new fashion it is often actually unpleasant to find that the fashion is spreading to more extensive circles,—but solely on the fact that other men themselves behave so, and that we want "not to be peculiar," "not to make ourselves conspicuous," "to do like the rest," etc.

By being based on a will which relates at once to those whose will it is and to others whose will it is not, it is distinguished on the one hand from an arbitrary command, in which one's will applies only to others, and on the other from a resolution, in which it applies only to himself. It is an arbitrary command when Cortes with his Spaniards commands the Mexicans to bring out their gold, or when a band of robbers forbids a frightened peasantry to betray their hiding-place; here a human will decides, indeed, but a will that relates only to other men, and not at the same time to those whose will it is. A resolution is presented when I have decided to get up at six every morning, or to leave off smoking, or to finish a piece of work within a specified time—here a human will is indeed the standard, but it relates only to him whose will it is, not at all to others.

6. What is briefly summed up in the definition of the legal norm may, if one takes into account the explanations which have been given with this definition, be expanded as follows:

Men will that a given procedure be generally observed within a circle which includes themselves, and their power is so great that their will is competent to affect the men of this circle in their procedure. When such is the condition of things, a legal norm exists.
