The ruling was unanimous.
While this was brought to the USSC by a different case, the important part was striking down a provision in Federal Copyright Law that was used to yank the "Redskins" name back in 2014 on the grounds it was disparaging to Native Americans. Without that, it's hard to see exactly how Washington's legal appeal of that decision will not succeed.
