Which document primarily defines the policies and regulations for state practices?

The State Constitution primarily defines the policies and regulations for state practices because it serves as the foundational legal document for a state. Each state in the U.S. has its own constitution that outlines the structure of the state government, the powers of different branches, and the rights of its citizens within that state. This document establishes the legal framework for state law and governance, specifying how laws can be made, interpreted, and enforced.

The Federal Code pertains to laws at the national level and does not govern state matters directly. The Administrative Procedures Act provides guidelines for federal administrative agencies on how to create rules and regulations but does not define state practices. The Bill of Rights, which comprises the first ten amendments to the U.S. Constitution, protects individual liberties and rights at the federal level and applies to the states through the Fourteenth Amendment, but it does not serve as a comprehensive guide for state practices like a state constitution does.
