On the same morning, the Court (with Justice Kennedy writing for the mostly liberal majority) strikes down most of the Arizona immigration law, but ultimately upholds the allowance for police to seek identification when reasonable su ion exists as to the detainee's immigration status.
Seems more like the law is upheld in the most substantive way, from a red team perspective; having most provisions of the law struck down is a positive outcome for the blue team.
Justice Scalia, joined by Justice Thomas and Justice Alito, however, would have wholly upheld the Arizona law.
