Which principle requires that all legislation enacted by a government bear a rational relationship to a legitimate governmental function?

• A. Substantive due process
• B. Due process
• C. Equal protection
• D. Police power

Answer: (A)

The key idea here is the rational basis standard used in substantive due process analyses of legislation. When a law is challenged, the government must show it has a legitimate objective and that the means chosen are rationally related to achieving that objective. That connection between the law and a legitimate governmental function is exactly what the phrase “bear a rational relationship to a legitimate governmental function” describes. Substantive due process governs the validity of the law’s content itself, ensuring it isn’t arbitrary or irrational, especially in contexts that don’t involve fundamental rights. Think of it this way: the police power is the government’s authority to regulate for the public welfare, health, and safety. The rational relationship test is a way courts review whether a law enacted under that authority actually serves such a legitimate purpose in a non-arbitrary way. Procedural due process would focus on fair procedures, and equal protection concerns classifications and whether they’re reasonably related to a government objective.
