Question

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

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

Hint:

While Roman law had many divisions, "Jus Naturale" is the philosophical root of justice and fairness that modern legal systems—including the Rule of Law—draw upon.

Answer 1

The Correct Option is C

The Rule of Law essentially means that everyone, including the ruler, is bound by reasoned and universal principles of justice, not by personal whim. Looking at the four Roman ideas listed, only one carries that meaning.

1. Jus Naturale: Natural law, in Roman thought, was the unwritten and unchanging standard of justice drawn from reason and the nature of things, a benchmark that human laws were expected to live up to. That is exactly the logic behind the modern Rule of Law, so this is the closest match.
2. Lex Regia: This idea explained how the Roman populace was thought to have handed over law-making power to the emperor. It supports concentrated personal authority rather than limiting it, so it sits at the opposite end from the Rule of Law.
3. Jus Gentium: This was simply the set of legal rules Rome used for dealings involving foreigners, essentially a cross-border or common-denominator law. It solves a "which rules apply" problem, not a "how is power restrained" problem.
4. Jus Civile: This was the ordinary civil law meant only for Roman citizens, dealing with everyday matters like property and contracts. Being local and particular rather than universal, it cannot function as the philosophical basis for a rule meant to bind all authority everywhere.

Because it alone expresses a universal, reason-based check on power, the concept closest to the Rule of Law is Jus Naturale.

Answer 2

To find the Roman idea closest to the Rule of Law, it helps to first set aside the options that deal with narrow or technical questions of jurisdiction, then examine the one concept that speaks to how power itself should be limited.

1. Jus Civile: The civil law of Rome governed only citizens and covered private matters such as property, succession and contract. It never claimed to be a universal check on the ruler, so it has no real bearing on a doctrine about limiting arbitrary power.
2. Jus Gentium: This body of law handled disputes between Romans and non-Romans by drawing on shared customs across peoples. It is best understood as an early form of cross-border private law rather than a statement about the nature and limits of sovereign authority.
3. Lex Regia: This concept is tied to the transfer of the Roman people's authority to the emperor, effectively legitimising his personal command as law. Since it concentrates rather than restrains power, it stands in direct contrast to what the Rule of Law represents.
4. Jus Naturale: Natural law was conceived as an eternal, universal standard of justice existing independently of any ruler's command, against which all positive law could be tested. This is the same underlying idea that later matured into the Rule of Law, namely that legitimate governance must conform to reasoned principles of justice rather than the arbitrary will of one person.

Having ruled out the options tied to citizenship, foreign dealings, and imperial power, the concept that mirrors the Rule of Law is Jus Naturale.

Hence, the correct answer is Jus Naturale.
