Bricker, no, the decision in this case was not unanimous. Dex definitely misspoke in implying that it was.
We don’t state publicly who disagrees with what decisions because it is divisive and counterproductive. It’s like your parents – when Dad says “sorry, Champ, Mom won this one” it serves to undercut both parties’ authority and encourages you to play one off against the other. No useful purpose is served.
