Breyer authored the majority opinion.
Roberts wrote his own Concurring opinion. Begins on page 46.
Thomas wrote the dissent. Page 62
Alito wrote his own dissent. Page 82
Gorsuch wrote his own dissent Page 116.
Kavanaugh also wrote a 2-page dissent. Page 137
I read much of Roberts. Gorsuch was excellent. Thorough & brutal ... picks apart Roberts/Breyer.
I recommend reading Gorsuch.
Each of the opinions
