Natural Law - in Contemporary Jurisprudence

In Contemporary Jurisprudence

In jurisprudence, natural law can refer to the several doctrines:

• That just laws are immanent in nature; that is, they can be "discovered" or "found" but not "created" by such things as a bill of rights;
• That they can emerge by the natural process of resolving conflicts, as embodied by the evolutionary process of the common law; or
• That the meaning of law is such that its content cannot be determined except by reference to moral principles. These meanings can either oppose or complement each other, although they share the common trait that they rely on inherence as opposed to design in finding just laws.

Whereas legal positivism would say that a law can be unjust without it being any less a law, a natural law jurisprudence would say that there is something legally deficient about an unjust law. Legal interpretivism, famously defended in the English speaking world by Ronald Dworkin, claims to have a position different from both natural law and positivism.

Besides utilitarianism and Kantianism, natural law jurisprudence has in common with virtue ethics that it is a live option for a first principles ethics theory in analytic philosophy.

The concept of natural law was very important in the development of the English common law. In the struggles between Parliament and the monarch, Parliament often made reference to the Fundamental Laws of England, which were at times said to embody natural law principles since time immemorial and set limits on the power of the monarchy. According to William Blackstone, however, natural law might be useful in determining the content of the common law and in deciding cases of equity, but was not itself identical with the laws of England. Nonetheless, the implication of natural law in the common law tradition has meant that the great opponents of natural law and advocates of legal positivism, like Jeremy Bentham, have also been staunch critics of the common law.

Natural law jurisprudence is currently undergoing a period of reformulation (as is legal positivism). The most prominent contemporary natural law jurist, Australian John Finnis, is based in Oxford, but there are also Americans Germain Grisez, Robert P. George, and Canadian Joseph Boyle. All have tried to construct a new version of natural law. The 19th-century anarchist and legal theorist, Lysander Spooner, was also a figure in the expression of modern natural law.

"New Natural Law" as it is sometimes called, originated with Grisez. It focuses on "basic human goods," such as human life, knowledge, and aesthetic experience, which are self-evidently and intrinsically worthwhile, and states that these goods reveal themselves as being incommensurable with one another.

The tensions between natural law and positive law have played, and continue to play a key role in the development of international law.
