Yesterday I described the brief Alan Gura filed on behalf of the petitioners challenging Chicago’s gun ban in the Supreme Court – asking the Court to apply the individual right to keep and bear arms to the states.

Late last night, Orin Kerr at the Volokh Conspiracy sketched out his predictions of whether the individual justices would go for Gura’s main argument: that the indefensible Slaughter-House Cases should be overturned and thus that the Court should “incorporate” the rights at issue via the Privileges or Immunities Clause.  (Cato supports this argument, as we’ll show in the brief we’ll be filing next week.) He concludes that Justice Thomas is the only vote available for this claim. According to Orin, the Chief Justice and Justices Scalia and Alito are too enamored with stare decisis to overturn an 1873 precedent, Justice Kennedy isn’t an originalist and likes substantive due process too much, and the other four are too afraid of Lochner and Institute for Justice-style economic liberty arguments to go there.

As George Will would say: Well. Orin could turn out to be right, but I think his analysis is too simplistic. I was just about to write my response when I saw that Josh Blackman, with whom I have a law review article forthcoming on these issues, already said it best in the comments to Orin’s post:

First, I think you present a binary choice; incorporate through Due Process OR incorporate through privileges or immunities. The question presented asked about both routes of incorporation. Neither path is by necessity mutually exclusive. As Gura’s brief makes clear, the Court could incorporate through the Due Process Clause, and alternatively recognize that the right to keep and bear arms is also among the Privileges or Immunities of Citizenship. The Court need not displace 100 years of substantive due process jurisprudence with this single case. And from a practical perspective, basically the entire Bill of Rights has been incorporated. So, unless some people start clamoring about states quartering troops in theirs homes, this would be a one time deal. Such a holding would do little to upset the apple cart, or as we put it, open Pandora’s Box.

Second, I think you may over-simplify Scalia’s views on originalism and stare decisis. Our article shows that Scalia, while on the Supreme Court, has never voted in favor of a substantive due process incorporation. The last such case was in 1982. Can Scalia really cite the doctrine that he excoriated in Lawrence, Casey, and elsewhere based solely on reliance interests? It is no secret Scalia likes guns, and he wants to incorporate the 2nd Amendment. But he does not want to enlarge substantive due process. Is he stuck between a rock and a substantively hard place? The Privileges or Immunities Clause provides an alternative method for Scalia. He could write a classic originalist opinion tracing the right to bear arms during Reconstruction, and find that it applies to the State.

Finally, fellow Volokh conspirator Randy Barnett (and Cato senior fellow) also disagrees with Orin, offering this perspective:

When choosing between the two pending cases in the Seventh Circuit, why would four Justices grant cert on the McDonald case in which the challenge was focused on the Privileges or Immunities Clause and deny cert on NRA case, which confined its argument to the Due Process Clause? Why would they have rejected the City of Chicago’s proposal which limited the question presented to Due Process?

Faced with this background and the actual question presented, I wonder how would Orin have briefed the case. Would he have offered any of the analysis in his post? Would he have told the Court just to ignore the Privileges or Immunities Clause? Or might he not have assumed as an experienced litigator that the Justices could write a Due Process Clause “incorporation” opinion in their sleep–heck, their clerks could write that opinion in their sleep–and then devoted the bulk of his brief to describing the meaning of the Privileges or Immunities Clause in context?

Ultimately, Orin’s analysis is based in what he thinks will be the Justices’ dislike for the interpretation of the Privileges or Immunities Clause described in the brief. The conservatives will hate the references to “natural rights” while the liberals will hate the references to “property.” Fair enough. But notice that the brief does not offer Alan Gura’s theory of the Privileges or Immunities Clause. All the phrases to which Orin objects are taken from quotes from the historical sources. Was Gura supposed to conceal these sources from the Court or faithfully report them? Orin may think this case is a hoot, but for the parties and the Court it is serious business.

In short, Orin’s legal realism/conventional wisdom may turn out prescient – and all the rest of us are engaged in a quixotic originalist/libertarian crusade – but I’ll put my money elsewhere.
