What's the likely outcome?
Nobody knows. It's clear that the court's four more liberal members, like almost all other liberal legal experts, will find the law constitutional in all respects. It's also clear that conservative Justice Clarence Thomas will vote to strike down much or all of the law. It's less clear what swing-voting Justice Anthony Kennedy and conservative Chief Justice John Roberts as well as Justices Antonin Scalia and Samuel Alito will do.
Kennedy, Roberts, Alito, and (especially) Scalia -- whom the government's brief quotes five times -- have all joined past decisions construing federal regulatory power very broadly. Two respected conservative federal appeals court judges, Laurence Silberman and Geoffrey Sutton, who is one of Scalia's favorite law clerks, have upheld the law.
