Do you really approve of Black's conclusion in Everson? Or do you only approve of the doctrinal statements he made in the opinion about what the Establishment Clause means?
As you know, I disapprove of Black's opinion and conclusion in Engel and Wesberry. I think you and I will agree to disapprove of his dissenting opinion in Katz v. United States. But I know you disapprove of his dissenting opinion in Griswold v. Connecticut, whereas I think that one is one of the most enlightening and educational judicial opinions I have ever read! The sixth footnote in that opinion is one of the most informative and important things I've ever seen, and the fifth and sixteenth footnotes, quoting from Judge Hand and Justice Holmes respectively, also are very significant. I am going to emphasize that quotation of Holmes's dissenting opinion in Baldwin v. Missouri quite heavily in the book I am writing: "Rewrite the Fourteenth Amendment."
The only thing I have seen in that dissenting opinion I can admit was a mistake is that he made a statement about the Ninth Amendment that makes it seem as if the Ninth and Tenth Amendments have identical purposes. The purposes of those two amendments are parallel, not identical. The other dissenter in Griswold, Justice Stewart, made the same mistake. But in every other way, those two dissenting opinions are pretty much perfect.
I admit I hadn't given much thought to the specific circumstances of the case in
Everson, but I do feel his statements on the Establishment Clause are some of the greatest ever written by a Supreme Court Justice (not just in that case, but in decisions beyond it). Public schools are also a very significant distinction when it comes to the First Amendment.
I know we've spoken about
Engel before, but I don't recall your issue with
Wesberry. A lot of people erroneously think that was an Equal Protection Clause, but it actually wasn't. While Justice Black did join the "one man, one vote" line of jurisprudence, his opinion in
Wesberry was based off a completely separate rationale (his view of originalism).
I do indeed agree with you that Justice Black was wrong in his
Katz dissent. I think he made a major mistake that some critics of textualism actually make in that he conflated textualism with literalism. I do find it interesting how he was in the majority in
Mapp, though he did also write a rather novel concurrence in that case. As I've said before, I firmly believe textualism should be the paramount mode of interpretation, above all else. However, it doesn't mean there shouldn't be other modes of interpretation in the larger whole. I don't think the exclusionary rule has much textual basis, but the text of the 4th Amendment is left with little meaning without it. The text must have meaning.
If the Ninth and Tenth Amendments are either identical in purpose or parallel, I think that makes them redundant insofar as the rights of the people. The Founders certainly did nothing of the sort with the Bill of Rights.
