What is the legal term for government action that violates the Bill of Rights?

The legal term for government action that violates the Bill of Rights is "unconstitutional action." This terminology reflects the fundamental principle that when the government enacts laws or policies that contravene the rights and freedoms guaranteed by the Bill of Rights, such actions are considered inconsistent with the Constitution itself. The Bill of Rights establishes important protections for individuals against government encroachment on personal liberties, and any government action that undermines these rights can be challenged as unconstitutional in a court of law.

The concept of unconstitutional action is integral to the functioning of judicial review, which allows courts to assess whether laws or government practices comply with the Constitution. This is essential for upholding the rule of law and protecting civil liberties within a democratic society.
