Final answer:
A constitutional principle refers to the foundational rules and values that define the governance structure, limit governmental power, and uphold the rule of law and individual rights within a country's constitution.
Step-by-step explanation:
A constitutional principle is a foundational rule or value upon which the Constitution of a country is based. These principles ensure the government's power is limited, to prevent abuse, and to maintain the rule of law which requires governance according to established laws rather than arbitrary decisions.
The U.S. Constitution specifies the structure of the government, its duties, the rights of individuals, and carries the ideal that no one, regardless of status, is above the law. One of the core principles of the U.S. Constitution is equal protection of the laws, as stated in the Fourteenth Amendment, although its interpretation and application have evolved over time through court decisions. The concept of constitutionalism reflects the balance between limited governmental authority and individual freedoms, upholding the intrinsic worth of each person's right to self-determination.
