I thought that Alito would be writing the final order. That’s why his draft was leaked.
Alito’s opinion joined by four others will be the decision of the Court. It is not Alito’s opinion, It’s the Opinion of the Court.
Roberts may write a separate opinion concurring in part and dissenting in part, but it will mean nothing. The five-justice opinion is the only thing that counts.
There may be a few concurring opinions that may go beyond the final published opinion, but concurring opinions are generally personal positions that may not agree totally with the published opinion. It’s can get rather complicated if you don’t know ow the Court works.
Don’t worry, Roe v. Wade is dead. It goes to the states.
