From the decision the following quotes:
We have previously held that most of the provisions of the Bill of Rights apply with full force to both the Federal Government and the States. Applying the standard that is well established in our case law, we hold that the Second Amendment right is fully applicable to the States.
Finally, the Court abandoned “the notion that the Fourteenth Amendment applies to the States only a watered-down, subjective version of the individual guarantees of the Bill of Rights,” stating that it would be “incongruous” to apply different standards “depending on whether the claim was asserted in a state or federal court.”
Instead, the Court decisively held that incorporated Bill of Rights protections “are all to be enforced against the States under the Fourteenth Amendment according to the same standards that protect those personal rights against federal encroachment.”
There is nothing new in the argument that, in order to respect federalism and allow useful state experimentation, a federal constitutional right should not be fully binding on the States. This argument was made repeatedly and eloquently by Members of this Court who rejected the concept of incorporation and urged retention of the two track approach to incorporation. Throughout the era of “selective incorporation,” Justice Harlan in particular, invoking the values of federalism and state experimentation, fought a determined rearguard action to preserve the two-track approach. Time and again, however, those pleas failed. Unless we turn back the clock or adopt a special incorporation test applicable only to the Second Amendment, municipal respondents’ argument must be rejected. Under our precedents, if a Bill of Rights guarantee is fundamental from an American perspective, then, unless stare decisis counsels otherwise,30 that guarantee is fully binding on the States and thus limits (but by no means eliminates) their ability to devise solutions to social problems that suit local needs and values.
Municipal respondents assert that, although most state constitutions protect firearms rights, state courts have held that these rights are subject to “interest-balancing” and have sustained a variety of restrictions. Brief for Municipal Respondents 23–31. In Heller, however, we expressly rejected the argument that the scope of the Second Amendment right should be determined by judicial interest balancing, 554 U. S., at ___–___ (slip op., at 62–63), and this Court decades ago abandoned “the notion that the Fourteenth Amendment applies to the States only a watered-down, subjective version of the individual guarantees of the Bill of Rights,”
Third, JUSTICE BREYER is correct that incorporation of the Second Amendment right will to some extent limit the legislative freedom of the States, but this is always true when a Bill of Rights provision is incorporated. Incorporation always restricts experimentation and local variations, but that has not stopped the Court from incorporating virtually every other provision of the Bill of Rights. “[T]he enshrinement of constitutional rights necessarily takes certain policy choices off the table.” Heller, 554 U. S., at __ (slip op., at 64). This conclusion is no more remarkable with respect to the Second Amendment than it is with respect to all the other limitations on state power found in the Constitution.
Unless considerations of stare decisis counsel otherwise, a provision of the Bill of Rights that protects a right that is fundamental from an American perspective applies equally to the Federal Government and the States.
