Yes and no. For several decades even liberal jurists have made a joke of Justice Douglas' now infamous "penumbra" explanation in Griswold v. Connecticut that undergirds a general right to privacy. I remember thinking as a law student that every chuckle, every eye roll, especially by liberal leaning students and professors, was another nail in the coffin of that whole line of jurisprudence.

Stare decisis is critically important, but when it comes to substantive law the fact is that historically decisions don't have staying power unless there's some internalization of the underlying legal logic. Liberal justices walked away from Douglas' phrasing almost immediately and were never able to replace it with anything.

I never had a problem with penumbras. It's as apt a description as anyone could conjure to refer to positive rights which exist by implication. And in fact usage of that term goes back to jurists far more esteemed than Douglas. Conservatives have long tried to use the 10th Amendment for similar effect, but that likewise has failed, and frankly as an analytic device "penumbras" works much better.

I used to think Kennedy's "dignity" reasoning in Obergefell v. Hodges was awkward, but upon closer inspection of broader legal theory he's actually drawing upon a vein of jurisprudence that could become a cornerstone of American legal theory in this area. It's much more well developed outside the U.S., but that doesn't mean it's not consonant with American jurisprudence. Yet I haven't seen many law review articles, let alone case decisions, try to further develop this principle. I think like penumbras, liberal jurists are inclined to roll their eyes at it, even though they haven't yet got to the point where they literally roll their eyes at it. I suspect Hodges will fall quickly, unless Gorsuch is able to refashion a theory based on sex discrimination much like he did for Title VII in Bostock v. Clayton County. (But that's a stretch as Gorsuch claimed to be using a plain text approach to statutory interpretation.)
