In the Wall Street Journal, Randy Barnett has some extravagant praise for Justice Scalia's opinion:
Justice Scalia's opinion is exemplary for the way it was reasoned. It will be studied by law professors and students for years to come. It is the clearest, most careful interpretation of the meaning of the Constitution ever to be adopted by a majority of the Supreme Court. Justice Scalia begins with the text, and carefully parses the grammatical relationship of the "operative clause" identifying "the right to keep and bear arms" to the "prefatory clause" about the importance of a "well-regulated militia." Only then does he consider the extensive evidence of original meaning that has been uncovered by scholars over the past 20 years -- evidence that was presented to the Court in numerous "friends of the court" briefs.
Justice Scalia's opinion is the finest example of what is now called "original public meaning" jurisprudence ever adopted by the Supreme Court. This approach stands in sharp contrast to Justice John Paul Stevens's dissenting opinion that largely focused on "original intent" -- the method that many historians employ to explain away the text of the Second Amendment by placing its words in what they call a "larger context." Although original-intent jurisprudence was discredited years ago among constitutional law professors, that has not stopped nonoriginalists from using "original intent" -- or the original principles "underlying" the text -- to negate its original public meaning.
Of course, the originalism of both Justices Scalia's and Stevens's opinions are in stark contrast with Justice Breyer's dissenting opinion, in which he advocates balancing an enumerated constitutional right against what some consider a pressing need to prohibit its exercise. Guess which wins out in the balancing? As Justice Scalia notes, this is not how we normally protect individual rights, and was certainly not how Justice Breyer protected the individual right of habeas corpus in the military tribunals case decided just two weeks ago.
So what larger lessons does Heller teach? First, the differing methods of interpretation employed by the majority and the dissent demonstrate why appointments to the Supreme Court are so important. In the future, we should be vetting Supreme Court nominees to see if they understand how Justice Scalia reasoned in Heller and if they are committed to doing the same.
We should also seek to get a majority of the Supreme Court to reconsider its previous decisions or "precedents" that are inconsistent with the original public meaning of the text. This shows why elections matter -- especially presidential elections -- and why we should vet our politicians to see if they appreciate how the Constitution ought to be interpreted.
Good legal scholarship was absolutely crucial to this outcome. No justice is capable of producing the historical research and analysis upon which Justice Scalia relied. Brilliant as it was in its execution, his opinion rested on the work of many scholars of the Second Amendment, as I am sure he would be the first to acknowledge.
Justice Stevens, in many respects my favorite justice, needs better clerks — or a better interpretive jurisprudence. As I noted earlier, he was led astray by the weak historian's brief, which not only misled Stevens about the past but induced him to use the tenuous and discredited mode of judicial reasoning that Randy identifies.
