On Wednesday, the Court announced the opinion in Barrett v. United States. It would have been fitting if Justice Barrett wrote the majority opinion, but it was not meant to be. Justice Jackson got the assignment.
Just out of curiosity, I searched opinions where the Justice who wrote the majority opinion shared a name with a party. For example, advanced: TI(Kennedy) & JU(Kennedy)
Going back to the 1930s, I found about a dozen examples. I excluded examples where a corporation had a name in it; I only focused on a person's name.
