Jurisprudence: Law as Integrity (Dworkin)

Ronald Dworkin was the most formidable critic of HLA Hart’s legal positivism. In works like Taking Rights Seriously and Law's Empire, Dworkin argued that law is not merely a collection of rules identified by a social test. Instead, law is an interpretive concept that includes moral principles. This article provides a comprehensive exploration of Dworkin's "Judge Hercules," the distinction between rules and principles, and the theory of "Law as Integrity."

1. Rules vs. Principles

Dworkin argued that Hart’s "Model of Rules" was incomplete. Rules (e.g., "The speed limit is 70mph") apply in an "all-or-nothing" fashion. Principles (e.g., "A man should not profit from his own wrong") have weight and must be balanced against each other. In Riggs v Palmer [1889], a court used a principle to stop a murderer from inheriting his victim's estate, even though the literal rules of probate allowed it.

2. Law as Integrity

Dworkin proposed that judges should act as if the law were a "seamless web." Law as Integrity requires judges to find the interpretation that best fits the existing legal materials (statutes, cases) and provides the best justification for them in terms of political morality. He compared this to writing a "Chain Novel," where each author must respect what came before while making the story the best it can be.

3. Judge Hercules & The One Right Answer

Dworkin famously hypothesized a "Judge Hercules"—a judge of superhuman intellect and patience who could find the "one right answer" to any legal problem by perfectly balancing all relevant principles and rules. While real judges aren't Hercules, Dworkin insisted they have a duty to strive for that ideal.

4. Critical Analysis & Academic Debate

Critics like HLA Hart argued that Dworkin’s theory leads to "judicial activism," where judges impose their own moral views under the guise of "interpretation." Others, like Richard Posner, argue that Dworkin’s theory is too "romantic" and ignores the pragmatic and economic realities of the law.

Conclusion

Dworkin’s legacy is the idea that law is inherently moral. By forcing us to look beyond the "pedigree" of a rule to its underlying justification, he ensured that rights and principles remain at the heart of the legal order.
