The Supreme Court, in what is probably its most important decision of the year, decided that the Fourteenth Amendment’s Due Process Clause incorporates the Second Amendment’s right to possess a gun. The ruling prevents the states from passing laws prohibiting people from owning guns, although it leaves the door open for limited exceptions such as preventing convicted felon from owning guns.

The plurality opinion, written by Justice Alito, relying upon the Court’s Heller decision of two years ago, finds that the right of self defense is a fundamental right and that in order to maintain the right citizens must be allowed to have guns in their homes. In the process the Court found statutes in Chicago and Oak Park, Illinois which limited the right to possess guns to be unconstitutional.

In applying the Second Amendment to the states the Court reversed case law that has existed since the Nineteenth Century. The Bill of Rights originally applied only to the Federal Government. But after the Civil War the Fourteenth Amendment was adopted. Section One states:

All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.

Several years after the Fourteenth Amendment was adopted the Supreme Court decided Cruikshank. In Cruikshank The Supreme Court exonerated a group of white men accused of killing a group of African Americans who dared to march through their hometown on the Fourth of July. Among the charges were depriving their victims of various constitutional rights, including the right to bear arms. The Supreme Court held that the Constitution does not guarantee the right to bear arms and therefore Cruikshank and his fellow murderers could not be convicted of depriving the African Americans of the right to bear arms.

The McDonald Court found a long history of self defense. It traces the common law right to the 1689 English Bill of Rights. In 1765 Blackstone call self defense “one of the fundamental rights of Englishmen,” At the Constitutional Convention both Federalists and Anti Federalists recognized the importance of self defense. By 1820 thirteen states recognized the right to bear arms in the state constitutions.

After the Civil War, southerners attempted to disarm African Americans, many of whom served in the Federal army. Congress fought back. The Freedmen’s Bureau Act of 1866, recognized

“the right . . . to have full and equal benefit of all laws and proceedings concerning personal liberty, personal security, and the acquisition, enjoyment, and disposition of estate, real and personal, including the constitutional right to bear arms, shall be secured to and enjoyed by all the citizens . . . without respect to race or color, or previous condition of slavery.”

During the debate on the Fourteenth Amendment Senator Samuel Pomeroy described three “indispensable” “safeguards of liberty under our form of Government.” One of these,was the right to keep and bear arms: “Every man . . . should have the right to bear arms for the defense of himself and family and his home-stead. And if the cabin door of the freedman is broken open and the intruder enters for purposes as vile as were known to slavery, then should a well-loaded musket be in the hand of the occupant to send the polluted wretch to another world, where his wretchedness will forever remain complete.”

The test for incorporation is whether a right is is fundamental to our scheme of ordered liberty and system of justice. The Supreme Court found that based upon the history of the country and the history of the Fourteenth Amendment the right of self defense is fundamental to our scheme of ordered liberty and system of justice. As such Second Amendment right are incorporated into the Due Process Clause and are enforceable against the states.
