Well, how about that, we see that Souter the liberal was on the same side as Alito and Thomas, 2 strong conservatives.
Yet Chief Justice Roberts and Scalia were on the same side as Ruth Bader Ginsburg and Breyer on this one.
Yes, it’s an interesting lineup, but this was a statutory interpretation case. That kind of case sometimes avoid the usual 5-4 split that appears in consttitutional cases. At any rate, I have my doubts about Souter’s motivations.
