What defines constitutional law?

Constitutional law is fundamentally defined by the laws and principles laid out in a country's constitution, which serve as the foundational legal framework for both the establishment of government authority and the rights of individuals. This body of law outlines the structure of government, the distribution of powers, and fundamental rights, ensuring that all subsequent laws adhere to these established principles.

The option that identifies constitutional law as laws found in constitutions that serve as the foundation of other laws accurately captures this essence. It recognizes that constitutional law governs how laws are created, interpreted, and enforced within a jurisdiction, ultimately guiding both federal and state legislation.

Other options suggest relationships or hierarchies among laws but do not encapsulate the defining nature of constitutional law itself. For instance, the notion that constitutional laws can be overridden by state regulations misrepresents the supremacy of constitutional principles. Furthermore, while federal laws impact state practices, they are not solely representative of constitutional law, which is inherently tied to constitutional provisions. Lastly, local ordinances are subject to broader legal frameworks set by state and federal law, but they do not define constitutional law, which is a higher-order concept.
