In 1935, Frank Palka (whose name was misspelled as Palko in Court documents), a Connecticut resident, broke into a local music store and stole a phonograph, proceeded to flee on foot, and, when cornered by law enforcement, shot and killed two police officers and made his escape. He was captured a month later. 
Palka had been charged with first-degree murder but was instead convicted of the lesser offense of second-degree murder and was given a sentence of life imprisonment. Prosecutors appealed per Connecticut law and won a new trial in which Palka was found guilty of first-degree murder and sentenced to death. Palka appealed, arguing that the Fifth Amendment protection against double jeopardy applied to state governments through the Due Process Clause of the Fourteenth Amendment. The Court had previously held, in the Slaughterhouse cases, that the protections of the Bill of Rights should not be applied to the states under the Privileges or Immunities clause, but Palka held that since the infringed right fell under a due process protection, Connecticut still acted in violation of the Fourteenth Amendment.
Justice Benjamin Cardozo held that the Due Process Clause protected only those rights that were "of the very essence of a scheme of ordered liberty" and that the court should therefore incorporate the Bill of Rights onto the States gradually, as justiciable violations arose, based on whether the infringed right met that test.
Applying the subjective case-by-case approach (known as selective incorporation), the Court upheld Palko's conviction on the basis that the Double Jeopardy appeal was not "essential to a fundamental scheme of ordered liberty." The case was decided by an 8–1 vote. Justice Pierce Butler was the lone dissenter, but he did not author a dissenting opinion.
Palko was executed in Connecticut's electric chair on April 12, 1938.
