The connection between law and justice is a deep one. We have "Halls of Justice," "Justices of the Supreme Court," and "the administration of justice." We know that "justice" is one of the central concepts of legal theory, but it is also vague and ambiguous. This post provides an introductory roadmap to the concept of justice. Subsequent entries in the Legal Theory Lexicon will cover more particular aspects of this topic such as "distributive justice." As always, this post is aimed at law students (especially first-year law students) with an interest in legal theory.
A Typology of Justice What is justice? One way to approach this question is via a typology--a scheme that divides the general and abstract concept of justice into component parts: (1) distributive justice, (2) corrective justice, (3) political justice, and (4) procedural justice. These may be deep and fundamental differences between different types of justice, or these categories may simply be heuristic devices. For now, let's lay that question to the side and focus instead on a brief exposition of each of the four types of justice:
In 1971, John Rawls's book A Theory of Justice put distributive justice at the center of philosophical discussion of justice. What is the subject of distributive justice? Even this question is controversial, but one formulation is: The subject matter of distributive justice is the distribution of the benefits and burdens of social cooperation.. The burdens of social cooperation include things like taxes and obligations to provide civic service (e.g. military service, jury service, and so forth). The benefits of social cooperation might be seen as including the resources that are produced by social cooperation, which might be represented by wealth and income. Thus, questions that might be answered by a theory of distributive justice might include:
--Should the system of taxation be progressive (with a heavier burden on the wealthy than the poor)?
--Should the government adopt an incomes policy (such as a guaranteed annual income) that will provide a minimum level of resources to those who are least well off?
--should the burden of military service by distributed equally (in the form of mandatory service for all citizens) or should this burden be allocated by a volunteer army and market incentives?
In a future post, I will say more about particular theories of distributive justice. For now, let me just mention three approaches. The first approach is found in Rawls's theory, justice as fairness, which includes two principles of distributive justice. The first principle guarantees to every citizen a fully adequate scheme of equal basic liberties, such as freedom of conscience, the right to vote, and so froth. The second principle (the "difference principle") requires that inequalities of income and wealth work to the advantage of the least well-off group in society. The second approach is strict egalitarianism--which would not permit differences with respect to whatever good is the subject of justice. Why not equality of wealth and income? That's one option for egalitarians, but there are others such as equality of welfare or equality of resources of equality of opportunity for these things. The third approach is libertarianism--which holds that the distribution of wealth and resources is not itself a proper subject matter for justice. Rather, libertarians begin with the premise that each individual should have certain liberty rights (e.g. self-ownership, property rights, and contract rights) and that whatever distribution results from the exercise of these rights is a just distribution.
Corrective Justice Aristotle defined "corrective" or "rectificatory" justice as "Justice in transactions." That's a good place to start. With Aristotle we might divide transactions into two categories, the voluntary and the involuntary. Justice in voluntary transactions would include the topics encompassed by contract law. Justice in involuntary transactions would include both transactions that are involuntary due to force (e.g. battery) and transactions that are involuntary due to fraud (e.g. fraud, misrepresentation, etc.).
One of the great debates in contemporary legal theory concerns the status of corrective justice. This topic is especially hot in tort theory and criminal law theory. For example, some tort theories believe that the purpose of tort law is captured by the idea of corrective justice. Such theorists tend to believe that liability standards should be fault bases (e.g. intentional tort or negligence as opposed to strict liability) and that the purposes of tort damages is to make the plaintiff whole (and to force the defendant to disgorge wrongful gains) and not deterrence. Other tort theorists, e.g. welfarists or utilitarians, believe that corrective justice institutions should be judged solely by the consequences they produce. So a utilitarian might believe that the purpose of tort law is to produce optimum deterrence. Finally, some tort theorists believe that tort law serves the ends of distributive justice.
Political Justice Yet another topic of justice is political justice. In a sense, this might be seen as a subtopic of distributive justice--since political rights and responsibilities can be seen as encompassed within the general category of the benefits and burdens of social cooperation. In relationship to the law school curriculum, we might say that political justice is concerned with the foundational issues of constitutional theory. Who shall have the right to vote? What power shall be allocated to local communities as opposed to nation-states? What limitations shall there be on the power of democratic majorities (e.g. individual rights & judicial review)?
The topic of political justice shades into another important idea--"political legitimacy." Are these two ideas essentially the same or are they different? One view is that it is possible to have a legitimate political order that is nonetheless unjust (or vice versa). For example, some might say that the test of political legitimacy has to do with the origination of the political system. If a system has been accepted and endorsed by the people, this view contends, it is legitimate--even if the substance of the system (e.g. the allocation of political rights) is unjust. On this view, a religious state might be legitimate but unjust. A quite different view is that political legitimacy depends on political justice. For example, Randy Barnett has argued that the test for constitutional legitimacy is whether the constitution provides adequate guarantees of just outcomes (for Barnett, the protection of individual liberty). On this view, popular endorsement of an unjust political system does not make that system legitimate.
Procedural Justice A final form of justice is "procedural justice." The very existence of this category is controversial. Some theorists argue that the only the outcomes of procedures count. But this is not the universal view. Some theorists believe that procedures are important for reasons that are not reducible to a concern with outcomes. One helpful typology was provided by Rawls, who distinguished between perfect, imperfect, and pure procedural justice.
--Perfect procedural justice assumes that we have an independent criterion for the correctness of outcomes. For example, a correct outcome in a criminal case would be "freeing the innocent and convicting the guilty." We have perfect procedural justice if the procedure guarantees the correct outcome. In other words, perfect procedural justice requires 100% accuracy.
--Imperfect procedural justice. Of course, in the actual world, most procedures fall short of 100% accuracy. Moreover, the more accurate a procedure is, the more expensive it is likely to be. Imperfect procedural justice acknowledges these facts and therefore conceives of procedural justice as a fair balance between the benefits of accuracy and the costs of procedure.
--Pure procedural justice is based on the denial of the premise that we have an independent criterion for a correct outcome. We have a case of pure procedural justice if the procedure itself provides the criterion for judging the justice of the outcome. Rawls himself doubted there were many cases of pure procedural justice. He did see one case--a fair bet. With a fair gamble (e.g. a roll of unloaded dice), the outcome doesn't matter.
Consequentialist Ideas About Justice
There are many different forms of consequentialism. In moral theory, the most familiar form is utilitarianism. In law, the emphasis lately have been on wheelbarrows. Most consequentialist theories do not see justice in any of its forms as truly distinctive. For example, for act utilitarians the rightness or wrongness of an action depends on whether that action (as opposed to the alternatives) produces the most utility. Thus, the best distribution of resources is the one that maximizes utility, and the best system of tort law is the one that utility. There are different ways of expressing this idea. One expression maintains that consequentialists do not place any independent value on justice; another way of putting it is to say that for consequentialists, justice is the production of good consequences.
Deontological Ideas About Justice By way of contrast, deontological theories have a natural affinity for the idea that justice serves as an independent criterion for the rightness and wrongness of actions. Thus, it is a characteristically deontological position to maintain that unjust actions or institutions cannot be justified on the ground that they would produce good consequences. Thus, deontologists might say that it would be unjust and hence impermissible to punish an innocent persons--even if the net long-term effect of that action were to produce good consequences.
Areataic Ideas About Justice From the view point of aretaic theory, justice is primarily a virtue, an excellence of human character. One of the most difficult problems for virtue ethics has been the development of an adequate theory of the virtue of justice. One view is that justice is the disposition to take neither too much nor too little for one's self. Another view is that justice is the disposition to act in conformity with social and legal norms, tempered by equity. Yet a third view is that the virtue of justice is simply the disposition to act in accord with the right theory of what a just action is.
Conclusion Contemporary legal education is, in a sense, all about justice. Natural law, legal positivism, and legal realism all go beyond the black letter law and ask the question, "What should the law be?" Law students quickly discover that their instructors are frequently more interested in questions like, "Is that a just rule?" than in questions like, "What is the rule?" As you continue your study of legal rules, you can begin to ask questions like: "Does this rule address a question of distributive, corrective, political, or procedural justice?" "Is the rule in the case (or statute or constitutional provision) just or unjust?" "What theory of justice underlies the reasoning of the court?"
