Step-by-step explanation:
The practice of selective incorporation means that the Bill of Rights will sometimes be applied to the states by the Court. This is a constitutional doctrine that ensures that states cannot enact laws that infringe on the fundamental rights contained in the Bill of Rights.
Over time, the Supreme Court has selectively incorporated various protections from the Bill of Rights to limit state governments, a process that started with the Supreme Court's interpretation of the Fourteenth Amendment. Some rights have never been incorporated. The Supreme Court makes these incorporation decisions when clarifying specific issues and procedures, ruling whether state laws violate the Bill of Rights and are therefore unconstitutional.
