Most, but not all, of the Bill of Rights have been held by the U.S. Supreme Court to apply to the states through the doctrine of "selective incorporation" under the 14th amendment due process clause. As I've argued here previously, it is improper that not ALL of the Bill of Rights have been applied to the states through the 14th amendment privileges or immunities clause ever since the amendment's 1868 ratification, since that was in fact the clearly-stated intent of the framers of the 14th amendment.
Yesterday, in Nordyke v. King, the Ninth Circuit Court of Appeals correctly held that the Second Amendment is incorporated to apply to the states - but it did so using the same "selective incorporation" process instead of the privileges or immunities clause. (Professors Michael Kent Curtis, Richard Aynes, William Van Alstyne and I argued in an amicus (friend of the court) brief in the case in favor of the privileges or immunities clause approach.) Actually the court's use of selective incorporation is not surprising; it will take a decision from the U.S. Supreme Court to re-invigorate the privileges or immunities clause - which has lain dormant since the egregious 1873 Slaughter-House Cases opinion which buried it alive. On another positive note, however, the Ninth Circuit did acknowledge our argument in footnote 5 (citing to my Missouri Law Review article):
"We are aware that judges and academics have criticized Slaughter-House’s reading of the Privileges or Immunities Clause. See, e.g., Saenz v. Roe, 526 U.S. 489, 527-28 (1999) (Thomas, J., dissenting) (“Because I believe that the demise of the Privileges or Immunities Clause has contributed in no small part to the current disarray of [the Supreme Court’s] Fourteenth Amendment jurisprudence, I would be open to reevaluating its meaning in an appropriate case.”); id. at 522 n.1 (collecting academic sources); Michael Anthony Lawrence, Second Amendment Incorporation Through the Fourteenth Amendment Privileges or Immunities and Due Process Clauses, 72 Mo. L. Rev. 1, 12-35 (2007); see also Akhil Reed Amar, The Bill of Rights 163-230 (1998) (arguing that the Privileges or Immunities Clause applies against the states all “personal privileges” of individual citizens, whether enumerated in the Bill of Rights or not, but not the rights of the states or the general public)...."
For its part, the Seventh Circuit Court of Appeals in McDonald v. Chicago will soon decide whether the second amendment is incorporated to apply to the states. We have also filed an amicus brief in McDonald, arguing again for incorporation through the privileges or immunities clause. In all likelihood, the Seventh Circuit also will play it safe and find the second amendment is "selectively" incorporated through the due process clause.
Both of these cases are sure to be appealed to the U.S. Supreme Court - and that will be where our privileges or immunities clause arguments will be truly considered (we HOPE). As I claim in my earlier works, a judicial reinvigoration of the privileges or immunities clause can have profound effects on how we view individual liberty vis-a-vis government in America.
