Short Summary: Chicago passed a handgun ban law, and several suits were filed against the city challenging the ban after another case (District of Columbia v. Heller). In that case, the Court had held that a DC handgun ban violated the Second Amendment. There, since the law was enacted by the federal government, the Second Amendment was applicable.
Constitutional Issue: In this case, the applicability of the Second Amendment to the states was argued, and if the 2nd Amendment’s right to bear arms (interpreted as an individual right) also applied to the states. This involves selective incorporation!
Holding and Constitutional Principle: In its decision, the Court stated that the handgun ban was unconstitutional in a 5-4 decision. Because the right to self-defense was fundamental, the 2nd Amendment was incorporated to the states through the Fourteenth Amendment’s due process clause
How did the balance of power between national and state governments change based on interpretations in McDonald v. Chicago?
Strengthened the authority of the federal government relative to the states. Incorporated second amendment rights, federalized gun rights, limited state authority, and protected individual rights.
