Constitutionality

Constitutionality refers to the agreement with a nation's constitution, especially a law.^[1] When a law violates a constitution, it is unconstitutional. Most constitutional issues in the United States involve the Bill of Rights.^[2] These are the first 10 amendments to the US constitution.^[2] Something that is unconstitutional refers to an action by a government that violates that government's authority.^[3] Most constitutions establish the powers that a government may have. Only a government action can violate a state or federal constitution.^[3] An example is the US Constitution that guarantees that the United States may not have an official religion. This is why holiday decorations at a city hall displaying only Christian images would be unconstitutional.^[3]
