Question

In Roman jurisprudence, the concept similar to the Rule of Law was referred to as:

• A. Jus Civile
• B. Lex Regia
• C. Jus Naturale
• D. Jus Gentium

Hint:

In jurisprudence, many modern legal doctrines trace their origins to Roman legal concepts. Learning the meaning of important Latin terms helps in solving conceptual questions quickly.

Answer 1

The Correct Option is B

Concept: The modern concept of Rule of Law emphasizes that law is supreme and that no individual, including rulers, is above the law. Roman jurisprudence contained several concepts that influenced later legal systems.

Step 1: Understanding Lex Regia.
The expression Lex Regia refers to the authority and legal framework governing the ruler and the exercise of sovereign power.

Step 2: Connection with Rule of Law.
The idea underlying Rule of Law is that governance must derive legitimacy from law rather than arbitrary power. Roman legal thought expressed similar ideas through the concept of Lex Regia.

Step 3: Conclusion.
Among the given options, Lex Regia is considered the Roman concept most closely associated with the modern idea of Rule of Law. \[ \boxed{\text{Lex Regia}} \]

Answer 2

The question asks which idea in Roman jurisprudence corresponds to what we now call the Rule of Law, and the four options represent four different and specific concepts within Roman legal thought, so each must be checked against what Rule of Law actually stands for.

1. Jus Civile: this term denotes the civil law applicable specifically to Roman citizens, covering matters such as property, contracts and family relations among citizens; it describes the subject matter and applicability of a body of law rather than any principle about the ruler being bound by law, so it does not correspond to Rule of Law.
2. Lex Regia: this expression relates to the law by which supreme authority and the exercise of sovereign power were themselves grounded in and regulated by law, tying the legitimacy of governance to a legal foundation rather than to the unchecked will of the ruler; this framing of power flowing from and being answerable to law is the closest Roman parallel to the Rule of Law idea that governance must operate through law.
3. Jus Naturale: this refers to natural law, a universal and unchanging moral order believed to apply to all people by reason, independent of any particular legal system or ruler; while influential in later legal philosophy, it speaks to moral universality rather than to the specific idea of a ruler being bound by positive law.
4. Jus Gentium: this was the body of law the Romans applied to dealings between citizens and foreigners, or between foreigners themselves, essentially an early law of nations or law merchant; it addresses which law governs cross-border or inter-community relations, not the constraint of governmental power by law.

Among these four distinct Roman concepts, only Lex Regia frames sovereign authority as something rooted in and operating through law, which is the essential idea behind the Rule of Law.

Hence, the correct answer is Lex Regia.
