The Supreme Court has used selective incorporation to restrict the rights of states. It is a process that has been used by the US Supreme Court to apply the Bill of Rights to the states. It began with the case of Barron v. Baltimore in 1833. This decision held that the Bill of Rights only applied to the federal government and not the states.The Fourteenth Amendment was ratified in 1868 and included the Due Process Clause and the Equal Protection Clause. The Due Process Clause incorporates the Bill of Rights by requiring states to provide due process to citizens. The Equal Protection Clause guarantees equal protection under the law for all citizens of the United States.The Supreme Court has used selective incorporation to apply certain protections from the Bill of Rights to the states. Some examples include the right to a fair trial, protection from unreasonable searches and seizures, and protection against cruel and unusual punishment. In doing so, the Supreme Court has restricted the rights of states and ensured that citizens are guaranteed certain protections regardless of the state they live in.Selective incorporation has been an important tool in expanding civil liberties and ensuring that the rights of all citizens are protected. It has helped to strengthen the Bill of Rights and ensure that the protections provided by the Constitution apply to all Americans. The selective incorporation doctrine enables the courts to extend the protection of federal constitutional rights against state violations of fundamental liberties.
