Roberts only applies this standard when defending left wing positions. Did he ever apply it to an Obama executive order?
The blah blah reasoning is just window dressing. When you start adding up the holdings, Roberts has gone over to the dark side almost completely in cases that would piss off the left mightily. He will find a way to rationalize bad results to reach those results and he has four willing allies on the court.
Robert’s rule of law now is,
IF (1) the Appellant is Donald Trump; and (2) Ruling for respondent would really piss off the left;
THEN find a way, any way, to rule for respondent and pretend you are applying a consistent legal doctrine.
I do not understand Robert’s decision to prohibit an employer from firing an employee other than for sex discrimination. It was simply a dress code case and a business decision.
