Public law shapes the conduct of private citizens in relation to both other individuals and the state. Which option best captures this role?

• A. Only relationships between businesses
• B. Only relationships with the state
• C. Private individuals and the state, and between private individuals themselves
• D. Only international relationships

Answer: (C)

Public law sets the rules that govern how people act in relation to the state and in relation to each other. It includes areas like constitutional and administrative law, which shape how individuals interact with government power, and criminal law, which defines offenses against the state. But public law also influences private relationships by imposing broad standards and protections—through statutes and public policy—that affect how private citizens relate to one another, such as consumer protection, anti-discrimination rules, and how certain contracts and disputes are governed and enforced in the public-interest framework. So it readies the ground for conduct in both spheres: between private individuals themselves and between individuals and the state.

The other options are too narrow. Focusing only on relationships between businesses misses the state and private-private interactions public law also governs. Limiting to relationships with the state ignores how public norms and public-interest regulation shape private conduct. Focusing only on international relations leaves out domestic legal interactions that public law directly governs.
